The small brown planthopper (SBPH), Laodelphax striatellus, is one of the most serious pest insects of rice plants.Buprofezin has been used to control SBPH for more than a decade, however, the occurrence of buprofezin resistant SBPHwas reported recently. To develop an alternative pest control an alternative pest control strategy, RNA-seq of buprofezin-treatedSBPH was performed to screen the insecticidal target genes for RNA interference (RNAi). Six genes were selected fordsRNA synthesis, and applied to SBPH to assess the insecticidal efficacy. Two and three of those dsRNAs showed moderatedand substantial insecticidal activity up to 60% of mortality in one week, respectively. These results demonstrated the potentialof gene screening strategy for the development of RNAi-based pest management program.

Entomopathogenic fungi have been widely studied for their potential as the effective biological control agents. Theyproduce variety of secondary metabolites with insecticidal activities, and it is reasonable to assume that entomopathogenicfungi might produce secondary metabolites modulating juvenile hormone for their survival against defense mechanismsof host insect. In this study, Acetone extracts of 189 entomopathogenic fungi cultured on unpolished rice medium werescreened for their juvenile hormone antagonist (JHAN) activities using the yeast-two hybrid system. Among them, 14extracts showed high level of JHAN activities and their insecticidal activities against Aedes albopictus were investigated.

Amblyseius eharai is a native predatory mite in Korea and a candidate of biological control agent to control spidermites. To evaluate the predation ability of A. eharai, its functional response was tested at 10, 30, 50, 70 and 130 larvaeof Tetranychus urticae. A. eharai showed the Type 2 functional response. The attack rate of female and male A. eharaiwas 0.109 and 0.019, respectively. The handling time of female and male was 0.164 h and 0.234 h, respectively. Theattack rate was significantly different between male and females at 95% confidence interval. However, handling time wasnot statistically different. In comparison with Neoseiulus californicus, attack rate and handling time of A. eharai werebetter than N. californicus. These result should be helpful for evaluation of A. eharai for a biological agent against T.urticae.

We compared the genetic structures of overwintered indigenous Korean and Chinese populations. The eight Koreanpopulations consisted of 33 haplotypes, and 16 haplotypes were newly identified. The genetic diversity of the Koreanpopulation revealed high haplotype diversity and low nucleotide diversity of 0.86 and 0.0024 on average, respectively,due to the high dispersal ability, which is similar to that of the Chinese population (Sun et al., 2015). Comparison with30 Chinese populations using a population tree showed that the Korean populations grouped with 12 Chinese populationsand that 67% were located near Jiangsu province. Moreover, the three frequent migration regions by migratory SBPH,including the Buan, Shinan and Taean counties, were grouped together with high supporting values. These results mightsupport the presence of gene flow between the Korean and Chinese populations by migratory SBPHs.

2010년 무렵부터 남부지방의 매실 과수원을 중심으로 수확 직전에 대부분의 과실이 낙과하는 원인은 복숭아씨살이좀벌 유충이 과일의 핵 속에서 씨앗을 섭식하기 때문이었고, 유충이 매실의 핵 속에서 성장하기 때문에 효과적인방제방법을 적용하기가 어렵다. 본 연구는 복숭아씨살이좀벌 암컷성충의 산란을 회피할 수 있는 방법을 살펴보고자2016년 전남북 5개 지역의 매실 과원에서 과일의 크기를 측정하였다. 복숭아씨쌀이좀벌 암컷성충의 산란관 길이는평균 5.0mm로 측정되었고, 매실의 핵이 형성되는 시기는 과일의 단경이 8mm 정도였으며, 20mm 이상이 되면 과육의두께가 5mm 이상이 되고 핵이 단단해졌다. 따라서 과일 단경이 8-20mm일 때 산란이 가능하며, 이 시기는 암컷성충의발생일과 거의 일치하므로 50% 우화일(지역별 4월 19일-28일)을 기점으로 5-7일 전과 후 3회 정도 약제를 살포하면산란회피가 가능할 것으로 확인이다.

It is necessary to understand of temporal and spatial dynamics by establishing a periodical monitoring system for theproper management in small brown planthopper (SBPH). A dataset is including the number of SBPHs by location, collectionmethod [aerial collection net (AeCN) or light trap (LT)] and period (May~Aug.) for five years (2011~2015), and missingvalues were imputed using multiple imputation methods. Of the 15,848 individuals collected, approximately 47% and 52.9%were collected using the AeCN and LT methods, respectively. A high incidence of migratory SBPHs was observed duringJulian days 144-166 using the AeCN method. Generally, the migratory SBPHs from China composed 39.4% of the totalpopulations of SBPHs. These results would provide valuable information to predict the incidence period of migratory SBPHsand establish a proactive management system against SBPH.

The red flour beetle, Tribolium castaneum, is one of economically important pests and can transmit several fungalspecies with their movement in stored grains. We collected T. castaneum samples from 34 rice processing complexes(RPC) nationwide during 2016-2017 and identified the contamination of fungal species on the surface of T. castaneum.Using sequence analysis of ITS region, 24 fungal genera were found. Among them, the genus Aspergillus spp. (28.8%)was the most frequently presented, followed by Cladosporium spp. (12.3%), Hyphopichia spp. (8.9%), Penicillium spp.(8.2%), and so on. In addition, as a known mycotoxin-producing fungal species, Aspergillus flavus (16 isolates) and Fusariumspp. (3 isolates) were also identified. Our study indicates that T. castaneum would play an important role in the contaminationof fungi and contribute potential production of mycotoxin in storage rice.

The two-spotted spider (Tetranychus urticae) is an important pest of many agricultural crops. Laboratory bioassayswere conducted to determine the toxicity of Pyflubumide and Cyenopyrafen against three populations of T. urticae collectedfrom apple orchards. The adults and eggs of three populations all showed susceptibility to Pyflubumide and Cyenopyrafen,as the 50% lethal concentration (LC50) values were all lower than each of the recommended concentrations. There wereconsiderable differences in susceptibility of the acaricides between eggs and adults in different populations. Pyflubumideshowed highest toxicity to adults of Yeongju population (LC50 = 1.40 mg/l) and eggs of Andong population (LC50 =0.54 mg/l). Cyenopyrafen showed lowest toxicity to adults of Andong population (LC50 = 20.29 mg/l) while displayedhighest toxicity to their eggs (LC50 = 2.64 mg/l). These results suggested that T. urticae had not developed resistancein these three regions, Pyflubumide and Cyenopyrafen can serve as alternative chemical candidate for integrated mite managementin apple orchards.

The potato tuber moth, Phthorimaea operculella (Zeller), is a ubiquitous pest on potatoes, tobacco, tomato and othercrops. The small hive beetle (SHB), Aethina tumida Murray, is a pest of European honeybees (Apis mellifera L.) in severalcountries in the world. Propolis is a balm-like substance collected from plants by bees. Its chemical composition variesand depends mainly on the flora in the region in which it is collected as well as the bee species. Hitherto biologicalproperties and the chemical composition of the essential oil extracted from propolis of Korean origin are unknown. Inthis study, while searching for an environmentally friendly method to control these pests we evaluated the repellent effectsof essential oil of propolis collected from Bee Lab of Andong National University and found that it possess repellentactivity against both small hive beetle and potato tuber moth. Moreover, a total of 171 constituents of the oil were identifiedof which 6 were major compounds using GC/MS analysis. We also compared the chemical composition of this oil withthose from 2 Ethiopian regions.

Nitiric oxide (NO) and eicosanoids function as crucial immune mediators in insects. This study focuses on cross-talkbetween two immune mediators in term of humoral immune response in Spodoptera exigua. Up-regulation of eight differentanti-microbial peptides (AMP) was observed against bacterial challenge. In contrast, injection of E. coli along with L-NAMEsignificantly down regulation the AMP production whereas D-NAME was not effective. The injection of E. coli withdexamethasone or SNAP also decreased AMP production whereas arachidonic acid (AA) compensated the dexamethasoneeffects. RNA inerferece against SeNOS showed the down-regulation of defensin mRNA level, whereas dsNOS injectionswith AA reversed the gene regulation.

Frankliniella intonsa (Trybom) (Thysanoptera: Thripidae) is an important pest in protected culture. We assessed fourrepellents (carvacrol, cis-jasmone, methyl jasmonate, and methyl salicylate) of Frankliniella occidentalis (Pergande)(Thysanoptera: Thripidae) known from literatures to develop a behavioral management tactic against F. intonsa. We measuredthe repellency of F. intonsa that exposed to 100 times diluted repellents on leaf disc. Repellency was 2.60 times higherin methyl jasmonate followed by methyl salicylate (2.16 times), cis-jasmone (2.15 times) and carvacrol (2.08 times) comparedto control. These results suggest that methyl jasmonate can be incorporated as a component of integrated managementof F. intonsa.

Orius minutus (L.) (Hemiptera: Anthocoridae) is a native predators of soft body insects such as mites, thrips, and aphids.We compared 24 h consumption rate of O. minutus with that of a commercialized O. laevigatus (Fieber) on egg andadult stage of Tetranychus urticae Koch (Acari: Tetranychidae). Orius minutus predated 1.4 times more adult T. urticae(58 mites) in 24 h than O. laevigatus. Similarly, O. minutus consumed 128 eggs while O. laevigatus consumed 98 eggsin 24 h without statistical difference. These results suggest that native O. minutus can be applied for the augmentativebiological control after the development of mass-rearing method.

As a broad-spectrum insecticide azadirachtin may cause acute toxicity and alter behavior of natural enemies. We evaluatedthe toxicity of azadirachtin on two egg parasitoids of Riptortus pedestris (Fabricius) (Hemiptera: Alydidae), Ooencyrtusnezarae Ishii (Hymenoptera: Encyrtidae) and Gryon japonicum (Ashmead) (Hymenoptera: Platygastridae), by pre-treatinghost eggs with five concentrations, i.e., 15, 10, 7.5, 5, and 2.5 mL/L. Azadirachtin significantly reduced parasitism byG. japonicum in 15 and 10 mL/L concentrations than other lower concentrations. Similar effect was also observed inO. nezarae. The parasitism reduction capacity (R) for G. japonicum was 40.8 and 33.1% in 15 and 10 mL/L concentrations,but it was 81.6 and 71.4% in O. nezarae, respectively. Based on the IOBC guideline, azadirachtin can be slightly ormoderately harmful to O. nezarae and slightly harmful or harmless to G. japonicum.

Potato tuber moth (PTM) is damaging pest of solanaceous crop invasive to Korea. We showed earlier that it inflicteddamage to tomato. So in this study, we evaluated accessions of Solanum lycopersicum (Money maker, Campari, AilsaCraig, LA3475 and e6203) and a wild variety of S. pimpinellifolium for resistance variability. A day old larvae of PTMwere inoculated to leaves and fruits. The result showed high survivability on leaves of Ailsa Craig (95.6%±4.4 SE) andlow on fruits of S. pimpinellifolium (14.0%±6.0). Leaves of LA3475 and fruits of S. pimpinellifolium were less preferred.Volatile compounds could be the cause. Density of trichomes could also influence PTM activity on leaves. These resultsgive us information on resistance variability which could be utilized if there is a host shift due to climate change.
