In the process of revising the tachinid genus Linnaemya Robineau-Desvoidy in Korea, we have discovered two species for the first time in Korea. They closely resemble each other and need to be identified with caution. We here provide detailed redescriptions and illustrations with their diagnostic characters indicated. L. atriventris can be distinguished from L. hirtipennis by the combination of the following characteristics: 1) abdomen black in ground color; 2) wing vein R1 without setulose; 3) hypandrium without secondary posterior lobe; 4) male with antero-basal 1/3 of flagellomere I distinctly swollen; and 5) postgonite very weakly curved dorsally.

Prorops Waterston is a small genus of the family Bethylidae (Hymenoptera) with just four species known worldwide: P. nasuta Waterston (cosmopolitan), P. petila Evans (Nearctic, Neotropical); P. obsoleta Evans (Neotropical); P. rakan Terayama (Palaearctic). A new species is recognized from the tropic rain forest of Cambodia. It is characterized from congeneric species by ‘the elongated median process on the lower part of frons and the flat-broad mandible downwardly developed’. The new species is described and illustrated with a key to world species of the genus Prorops.

In a revision of four Eurydema speices recorded in Far East Asia, we confirm only two species, one of which consists of two subspecies: E. dominulus (Scopoli 1763) [=E. pulchra (Westwood 1837), syn. nov.], E. gebleri gebleri Kolenati 1846, and E. gebleri rugosa Motschulsky 1861 [stat. nov.]. In order to prove the above taxonomic changes, we compared three major characters; (1) the color patterns, (2) the mitochondrial COI (DNA barcoding) and (3) cross– breeding fertility (inter–specific copulation). Two subspecies, E. g. rugosa and E. g. gebleri, preserve their own unique coloration patterns, confirmed by the intra–subspecific copulation and breeding. Interestingly, the 1st progeny from the inter–subspecific copulation of E. g. rugosa♂ X E. g. gebleri♀ (or E. g. gebleri♂ X E. g. rugosa♀) take the coloration patterns inherited from E. g. gebleri.

The genus Illinoia is originally distributing in North America, few species found in other continents as exotics with the introduction of their hosts as ornamental plants and weeds. Recently, we confirmed two Illinoia species in Korea as the first record of this genus in the Eastern Part of Palaearctic: Illinoia goldamaryae (Knowlton 1938) on Erigeron sp. (Asteraceae) and I. liriodendri (Monell 1879) on Liriodendron tulipifera (Magnoliaceae). Two exotic aphids are illustrated, diagnosed, and discussed for their host plants, distribution, etc.

We reviewed the Korean species belonging to the Tribe Dendrometrini. Of the previous Korean records. Athousius humeralis (Miwa, 1927) and Limoniscus rufipennis (Lewis, 1984) are confirmed as the misidentification of Ampedus basalis (Mennerheim, 1852) and Corymbitodes sp. recorded by Kishii and Paik (2002), respectively, and, in addition, the records of Limonius eximus (Lewis, 1874) and Limoniscus vittatus (Candeze, 1873) are also questionable since no specimens available in this study. A new species Cidnopus sp. nov. and a new record of Cidnopus koltzei (Reitter, 1895) is recognized in Korea. Limonius scutellaris (Dolin, 2003) comb. nov. is newly proposed. Tribe Dendrometrini Gistel, 1856 Athousisu humeralis (Miwa, 1927) - misidentification Cidnopus sp. nov. Cidnopus koltzei (Reitter, 1895) - new to Korea Limonius eximus (Lewis, 1894) - Korean specimen unavailable Limonius scutellaris (Dolin, 2003) comb. nov. - new to Korea Limoniscus kraatzi kraatzi (Candèze, 1879) Limoniscus vittatus ((Candèze, 1873) - Korean specimen unavailable Limoniscus rufipennis (Lewis, 1894) -misidentification

The sweetpotato whitefly, Bemisia tabaci, is a vector of more than 100 plantdiseased viruses as well as a serious pest to various horticultural crops. Virus acquisition affects the vector’s development and reproduction, but its mechanism is largely unknown. Here we compared the temperature responses between non-viruliferous and TYLCV-viruliferous Q biotype of B. tabaci. When both non-viruliferous and viruliferous whiteflies were exposed for 1 and 3 h at 4, 25, and 35°C, the mortality rate of viruliferous whiteflies is higher than nonviruliferous after exposure at 4°C and 35°C, but no differences at 25°C between them. Analysis of the expression levels of heat shock protein (hsp) genes using the quantitative realtime PCR showed that viruliferous whiteflies has higher expression in hsp70, and hsp90 at both 4°C and 35°C, but no differences at 25°C. The results suggest that vector insects may not be durable to unfavorable temperature conditions when they acquisite plant viruses.

Temperature and nutrition are the two most important environmental factors influencing growth and survival in immature insects. There is ample evidence of interactions between these two factors but still little is known how changes in thermal environment affect feeding and nutrient utilization insect ectotherms. The aim of this study is to investigate the potential effects of ambient temperature on food selection and post-ingestive nutritional physiology in a generalist-feeding caterpillar of Spodorptera litura. Two separate experiments were performed. The first was a food choice experiment in which caterpillars were maintained through their final larval stadium under one of three constant temperatures(20,25,30°) and given a choice between two nutritionally unbalanced diets that differed in protein(p) and carbohydrate(c) content (p42:c0 vs p7:c35 and p35:c7 vs p7:c35). In the second experiment, caterpillars were kept at the same thermal conditions as the first experiment but received a single diet from three no-choice feeding treatments(p35:c7,p21:c21and p7:c35). When raised at the highest temperature (30C), caterpillars from the choice experiment selected significantly more carbohydrate than those on lower temperatures whereas protein intake did not differ significantly between caterpillars across three test temperatures. Results from the no-choice experiment showed that lipid storage efficiency was reduced when caterpillars were maintained at the highest temperature(30C). In both experiments, growth rate increased progressively with rising temperature. However, there was a significant temperature-by-diet interaction, with growth rates increasing more rapidly on p21:c21 diet than on the other diets(p35:c7 and p7:c35). Our results demonstrate that caterpillars adjust their nutrient preference to meet the increased energetic demand at high ambient temperature.

The sweetpotato whitefly, Bemisia tabaci, acts as a vector of more than 100 plant viruses. B. tabaci is known to harbor a primary endosymbiont (Portiera) and 6 secondary endosymbionts (Arsenophonus, Cardinium, Fritschea, Hamiltonella, Rickettsia and Wolbachia). These endosymbionts play important roles in the acquisition and transmission of plant viruses. Using PCR analysis, we identified endosymbiotic bacteria in various B. tabaci populations collected from different places of Korea. Distribution of endosymbionts was different according to the biotype of B. tabaci. Subsequently, their relative densities of endosymbionts were compared between TYLCV-viruliferous and non-viruliferous populations of the Q biotype using quantitative realtime PCR. We found that the densities of Portiera, Cardinium and Hamiltonella are higher in viruliferous than non-viruliferous whiteflies. Our results suggest the role of endosymbiont for the TYLCV transmission of whiteflies.

Cinnamaldehyde as the main component of Cinnamomum plants is well known as mammalian transient receptor potential ankyrin 1 (TRPA1) agonist, also activated by low temperature stimuli and mechanosensation. The other TRP subfamily, transient receptor potential vanilloid-1 (TRPV1) sensitive to pungent compounds such as capsaicin and allicin mediates the feeling of warmth. Both TRPA1 and TRPV1 channels are abundantly distributed in sensory neurons. Thus, there is possibility that these channels modulate repellent behaviors of mosquitoes and Drosophila through olfactory receptor neurons (ORNs). In order to confirm this hypothesis, we carried out laboratory repellent tests with cinnamaldehyde to Aedes aegypti females using arm-in-cage test and to a wild type and two TRP channel mutants Drosophila lines using a choice assay. Cinnamaldehyde showed strong repellency against Ae. aegypti and Drosophila wild adults at tested concentrations. However, a mutant fly line did not discriminate or detect the existence of the repellent. These behavioral data suggest that cinnamaldehyde may directly target the TRP channel. More studies to elucidate neural correlates of repellency to ainnamaldehyde compound are as follows: 1) Identifying the ORNs mediating cinnamaldehyde detection using single-sensillum recording techniques, 2) Co-localization of TRP genes on olfactory organs of Ae. aegypti and Drosophila using in situ hybridization and 3) Whether the Aedes TRP homologs might function in cinnamaldehyde repellency using rescued TRP chennels of Drosophila.

Monoalkenyl acetates are used as one of lepidopteran pheromone components. However, (Z)-3-alkenylacetate as pheromone components is rarely known. Among them, (Z)-3-dodecenylacetate is used as pheromone components of Aproaerema anthyllidella and Tecia solanivora. Recently, (Z)-3-dodecenylacetate was identified as one of pheromone components for an insect pest in Korea (unpublisheddata). For the demand of development of mating disruption against thepest, large amount of (Z)-3-dodecenylacetate (Z3-C12Ac) was needed. Here, we reported the synthetic procedures for (Z)-3-decenylacetate (Z3-C12AC). The Grignard reagent from 1-decyne and ethyl magnesium bromide was reacted with ethylene oxide in dry tetrahydrofuran (THF). Thus synthesized 3-dodecyn-1-ol was reduced to (Z)-3-dodecen-1-ol (Z3-C12OH) by hydrogenation over Lindlar’s catalyst. The alcohol was acetylated to desired (Z)-3-dodecenylacetate (Z3-12Ac) with acetic anhydride by general procedures. The yield was 62.6% through the all procedures. Thepurity was 98.0% (by GC-MS). The isomeric purity was >99% (by NMR).

In the previous study, we found an orange-eyed mutant of the brown planthopper (BPH). And we confirmed that it’s orange phenotype is controlled by single recessive allele in the autosome. To understand the effect of the orange eye color on mating of BPH, we designed two different combinations of the mate choice test with three virgin female and male BPH adults. The one consisted of orange-eyed female (org/org), orange-eyed male (org/org), and homozygous normal-eyed male (+/+) (female mate choice). The other was composed of orange-eyed male (org/org), orange-eyed female (org/org), and homozygous normal-eyed female (+/+) (male mate choice). In female mate choice test, four mating types could be distinguished according to the distribution of the eye-color phenotype in F1 progeny and their hatching-order in each mating pair. Two mating types showed only one eye-color phenotype, normal and orange, respectively, and the other two produced both eye-color phenotypes in a different hatching-order. In male mate choice test, both phenotypes of offsprings were also produced in most mating pairs. From these results, the effect of eye color on mating of BPH was not clearly found, but the multiple mating in both sexes and the mating preference by female are cautiously suggested.

Paratlanticus ussuriensis enter prolonged diapause at an egg stage. Environmental conditions, such as temperature, can modify the diapause duration at initial diapause. Eggs enter initial diapause at 20℃, but continued early embryonic development at 30℃. Final diapause at a fully developed embryonic stage is obligatory regardless of temperature conditions. To determine temperature effects on diapause mechanism of P. ussuriensis eggs, we compared weights, DNA and RNA amounts of eggs incubated at either 20℃ or 30℃ for 50 days after oviposition. Both egg weight and total amount of DNA were constant at 20℃ but gradually increased at 30℃. However, total RNA level was rapidly increased at 15 days-old eggs at 30℃ and maintained high levels during further period whereas its level was constant at 20℃. In addition, we identified three heat shock protein 70 (hsp70a, hap70b, hsp70c) genes of P. ussuriensis and determined those expression levels at different temperature conditions. The levels of hsp70a and hsp70b was not detectable until 20 days after oviposition at both temperature conditions, but highly increased at 50 and 60 days when incubated at 30℃. In contrast, hsp70c level was rapidly peaked at 20 days after oviposition, which is the time of initial diapause entrance. Our results suggest that high temperature breakdown initial diapause and a certain hsp gene, such as hsp70c, may involve in the initial diapause mechanism of P. ussuriensis eggs.

Alzheimer’s disease (AD) is a fatal disorder wherein patients suffer from sensory, motor, and cognitive loss. Currently, the identification and validation of biomarkers for diagnosing AD and other forms of dementia are increasingly important. Olfactory dysfunction is present in patients diagnosed with Alzheimer’s disease or idiopathic Parkinson's disease. Alzheimer’s patients show neuropathological changes in areas of the brain central to the olfactory processing center, suggesting the theoretical importance and potential diagnostic utility of investigating functional changes in olfaction in these patients. However, the usefulness of olfactory screens to serve as informative indicators of Alzheimer’s is precluded by the lack of knowledge regarding neural and molecular mechanisms underlying olfactory dysfunction onto Alzheimer's diseases. To test these ultimate questions, we used molecular and electrophysiological recording techniques to find out the difference of olfactory responses and AD related protein expression patterns by using fly model, Drosophila melanogaster that over-expresses the human β -amyloid, tau protein. We postulated that such flies would present with progressive olfactory impairments compared with age-matched wild type control flies. In this study, our hypothesis is that there is a correlation between olfactory deficits and the spatial expression pattern of β-amyloid and tau protein deposition. Therefore, we demonstrate a specific concentration of lesions in central olfactory structures such as antenna and Maxillary palps. Our study indicates that deficits on olfactory identification may occur in AD, which will be valuable as an indicator of neuropathogenesis.

팥나방(Matsumuraeses phaseoli)과 어리팥나방(M. falcana)은 외부 형태로 쉽 게 구분할 수 없으나, 수컷 생식기 형태와 미토콘드리아 시토크롬 옥시다제 I 유전 자 염기서열에서의 차이가 보고되어 왔다. 또 두 종이 성페로몬으로 3개의 화합물 을 같이 사용하고 있으나, 그 조성은 서로 다른 것으로 보고되었다. 그러나 각 종에 대해 밝혀진 조성으로 제작된 합성 성페로몬 미끼를 이용하여, 야외에서 각 종을 트랩에 유인하고, 포획된 수컷들의 생식기 형태와 미토콘트리아 옥시다제 I 유전 자 표지로 종을 구분한 결과는, 각 곤충종의 트랩에 두 종이 동시에 유인되는 것을 보였다. 이 결과는 한편으로 성페로몬 조성이 각 종에 대해 완벽하게 밝혀지지 않 았을 가능성과, 다른 한편으로 야외에서 이들 두 종이 생식적으로 완전하게 분리 되어 있지 않았을 가능성을 나타내었다. 또 두 종의 교잡실험에서도 후대 세대가 생성될 수도 있음을 보였다. 따라서 본 연구에서는 각 종의 짝짓기 통신에 절대적 인 특이성이 있는가를 관찰하기 위해 처녀 암컷을 미끼로 이용하여 수컷을 포획하 는 시도를 하였다. 결과에서 어리팥나방 암컷 트랩에 잡힌 수컷들의 대부분은 어 리팥나방이었는데, 팥나방 암컷 트랩에 잡힌 수컷들에서는 팥나방 보다는 어리팥 나방의 수가 더 많았다. 미끼를 설치하지 않은 트랩에는 두 종 모두 포획되지 않아, 이 결과가 우연한 것이 아님을 보였는데, 결국 이 결과로 두 종 사이에 생식 격리 메커니즘이 완벽하게 작동하고 있지 않다고 추정하였다.

From our previous studies in a farm in Songcheon, Andong where a series of crops was cultivated in 2008 and 2009, occurrence patterns of Riptortus pedestris (Fabricius) (Hemiptera: Alydidae) and its egg parasitism by Ooencyrtus nezarae Ishii (Hymenoptera: Encyrtidae) and Gryon japonicum (Ashmead) (Hymenoptera: Scelionidae) were reported. With an objective to verify the trend of the occurrence pattern, a year long monitoring of R. pedestris and its egg parasitism was continued in 2010 in the same location where barley, sesame, and soybean were cultivated in series. We placed four aggregation pheromone traps added with 50 refrigerated eggs of R. pedestris each along the perimeter of the field from 11 April to 31 October. Weekly occurrence patterns of R. pedestris and its parasitism in 2010 were generally similar to the patterns of previous years. Riptortus pedestris population first appeared in the last week of April, peaked after the third week of August, and declined in October. Parasitism by G. japonicum was recorded up to 64% in July, 2010 which was much higher than previous years. This study verifies that G. japonicum is the first colonizer that appears as early as May and remains active until September. Ooencyrtus nezarae, however, starts to occur late from the last week of August and exist in the field until October.

Apple borers such as oriental fruit moth (OFM) Grapholita molesta (Busck) (Lepidoptera: Totricidae), and peach fruit moth Carposina sasakii Matsumura (Lepidoptera: Carposinidae) can reduce the yield and its quality if not managed properly. Even peach fruit moth infestation in harvested apple could produce quarantine problem in exportation. We investigated the temporal distribution of apple borers infestation in an apple orchard where the infestation level of fruit was around 95% from September to early December, 2010. Every week, 150 apples were harvested from the apple orchard in Giran, Andong, Korea and 50 apples were cut to monitor the number of larval infestation. At the same time another 100 apples were kept in plastic container inside and outside the laboratory 50 each to check the escape of the infested larvae for overwintering cocoon formation. All larvae collected were identified based on the morphology and also verified by DNA sequence. The study indicates that the numbers of the infested larvae increased from September to October second week and then slightly decreased until early December with similar number of holes per apple. The holes produced by the escaping larvae were mostly found on dorsal side of the apple, but less on basal portion. Most of the infested larvae escaped from apple during late October to early November. Based on morphological characters such as anal comb, crocket and pupation shelter, the collected larvae were identified. 42.31% of larvae were G.molesta, 52.59% of larvae were C.sasakii and 5.10% were other species not identified.

Light brown apple moth, Epiphyas postvittana, is a significant horticultural pest native to Australia, and currently with a limited global distribution. However it can tolerate very heterogeneous climatic and vegetation conditions and has recently invaded California with considerable consequences for US international and domestic trade. A genetic factor that may contribute to its environmental adaptability, and consequently invasive capability, is the phosphoglucose isomerase gene (pgi). This gene codes for a key enzyme in the second step of glycolysis and for which the isozyme composition has been associated with the fitness and dispersal capacity of other moths. As a first step, to determine if this locus is variable within E. postvittana, novel primers were designed enabling access to 957 bp of the coding region across exons 4 to 11 of pgi. Exon-primed intron-crossing (EPIC) primers were then designed to compare sequences of 17 specimens across one laboratory and three wild New Zealand populations from a laditudinal range of ~39-45°S. A total of 70 segregating sites in the exons were found, including 61 synonymous and nine nonsynonymous. Introns 3 to 11 (excluding intron 10) were also sequenced for 13 individuals revealing significant length variation within and between introns and populations. The level of variation revealed here indicates that this could be a useful target gene to assess fitness factors associated with invasibility of E. postvittana.

In order to achieve the optimized pest control, correct estimation of pest densities is a prerequisite to monitor pest damage and to provide efficient pest management plans. Parameters regarding diffusion (e.g., diffusion constant) and population size (e.g., growth rate) were estimated by using diffusion equation. The time series dispersal data of Whiteflies collected in greenhouse were used for modeling. Cross-correlation analysis was conducted to reveal the range and direction of pest population invasion. Sampling theory was further investigated regarding estimation of densities, and population dynamics of Whiteflies were discussed in two dimensions.
