Asitic apple leafminer, Phyllonorycter ringoniella Matsumura, is an important pest in apple orchard, however its reproductive characteristics and seasonal adaption is poorly understood. The longevity and fecundity of P. ringoniella were investigated at seven constant temperatures (13.7, 15.6, 20.5, 23.7, 26.1, 30.2, and 32.3℃), 60-80% RH, and a photoperiod of 14:10 (L:D) h. Female adult longevity increased as the temperature decreased. The highest fecundity was obtained at 15.6℃ (65.2 eggs/female), and the fecundity decreased as temperature increased. The oviposition model were comprised by four components: adult aging rate model, total fecundity model, age-specific oviposition rate model, and age-specific survival rate model. Female adult aging rates were well described by an inverse second-order polynomial function and the total fecundity model was well described by an extreme value function. Age-specific cumulative oviposition rate was well fitted to a three-parameter Weibull function and age-specific survival rate to a sigmoid function, respectively. The model would be useful in developing population model for P. ringoniella and establishing management strategy against P. ringoniella in apple orchards.

RNAi (RNA interference) is a tool for silencing of target genes through sequence-specific manner. Spodoptera exigua belongs to Noctuidae family of Lepidoptera and is serious threat to crops of economic importance. One of S. exigua chymotrypsin gene (SeCHY2) was cloned into the L4440 vector to produce sequence specific dsRNAs (double-stranded RNAs). Recombinant L4440 vectors were transformed into Escherichia coli strain HT115 (DE3). Oral delivery of bacterially expressed dsRNA gave significant larval mortality. Quantitative real-time PCR results showed that expression level of target SeCHY2 gene in the larval gut tissue was significantly down-regulated. Pretreatment with an ultra-sonication and heating to disrupt bacterial cell wall/membrane significantly increased the insecticidal activity of the transformed bacteria

Monitoring of four major lepidopteran pests in corn field and management of the Helicoverpa armigera
Increasing Lepidopteran pests such as Helicoverpa armigera are emerging pests of corn in Korea. They cause huge yield losses and deteriorate the quality of corn crop. We monitored the four major lepidopteran pests in major highland corn growing areas of Korea by employing sex pheromone trap during 2012 to 2015 for understanding those population dynamics. Among these species, H. armigera was found to be the main pest based on the damage intensity (80 ~ 90% of total damage). Some effective insecticides were selected such as Indoxacarb etc. Optimal timing of spraying was estimated at around 70 days after planting (earing season) to control H. armigera. Additional, two species of parasitoids (Therion circumflexum and Ophioninae sp.) was identified from H. armigera. However, more extensive survey for natural enemies is needed to set the natural enemy based control program.

Negative effects of insecticides on non-target organism can be reduced by using selective and less toxic insecticides. We assessed the effect of subsequent application of flonicamid and Beauveria bassiana GHA on pests and natural enemies in soybean fields by recording their density in 6-8 d interval. Flonicamid controlled Aphis glycines Matsumura in 6 day after spray (DAS). Nymphs of Riptortus pedestris (F.) were also reduced by 46 and 48% in 12 and 19 DAS, respectively. Application of B. bassiana reduced R. pedestris nymph 50% in 16 DAS whereas adult R. pedestris, Medythia nigrobilineata Motschulsky and A. glycines were not significantly reduced in treated fields. Ladybird beetles, syrphid flies, hymenopteran wasps, and parasitism rate of R. pedestris eggs were not different between the treatment and control. These results suggest that flonicamid and B. bassiana showed less negative effect on the natural enemies and effective against aphids and nymphs stage of R. pedestris.

Tomato yellow leaf curl virus (TYLCV) causes a highly serious disease in tomatoes in many countries. The most important thing in management is the prevention of virus transmission. TYLCV had been known to be only transmitted by a vector, the sweetpotato whitelfy, Bemisia tabaci. However, we identified two other important routes of TYLCV transmission into tomatoes. It is seed-transmissible. Many seeds available in domestic and global markets were infected by TYLCV. It is also infective into various weeds and other horticultural crops and transmit virus through vector insects. Therefore, we need a new strategy for the virus and vector management.

Agrobacterium tumefaciens-mediated transformation (AtMT) has been widely used for generation of fungal transformants and recently applied to Beauveria bassiana. In this study to comprehend how the AtMT promoter influences on the expression of selection marker (hygromycin B resistance gene; hph), two different Ti-Plasmids were constructed: pCeg (gpdA promoter-based) and pCambia-egfp (CaMV 35S promoter-based). Putative transformants were subjected to the PCR, RT-PCR and qRT-PCR to inspect the T-DNA insertion rate and gene expression level. In conclusion, more than 80% of the colonies succeeded in AtMT transformation and the hph expression level of AtMT/pCeg colonies was higher than that of AtMT/pCambia-egfp colonies. This result can provide useful information on the AtMT of B. bassiana, especially antibiotics susceptibility and promoter-dependant expression level.

Effects of temperature on development and ovipistion of Amblyseius eharai, were examined at 11 constant temperatures (18.0, 20.1, 21.6, 24.0, 24.1, 27.4, 28.6, 30.2, 32.0, 33.2 and 35.9 °C), and six constant temperatures (18.0, 21.6, 24.1, 27.4, 30.2 and 33.2 °C) by using Tetranychus urticae as prey. Developmental rates were fitted with a nonlinear Briere 1 model, which estimated optimal temperatures for the development as 30.6 °C for total immature stage. In a linear model, the lower thresholds and thermal requirements (DD) were 13.2 °C (71.94 DD) for total immature stage. Fecundity was well described with the Extreme value function, which indicated optimal temperatures for the oviposition as 24.3 °C. Overall, findings herein provide comprehensive data and explanations on the temperature-dependent development and oviposition of A. eharai, and prove the probability of A. eharai as a good biological agent for T. urticae in early or late crop seasons, and/or at low temperature cultivation farm lands.

Potato tuber moth (PTM), phthorimaea operculella, invaded into Korea in 1968 but recently expanding the distribution possibly due to climate change. Ten insecticides were evaluated against the neonates and eggs of PTM. Vial contact test for neonates and dipping for eggs were conducted. LT50 at recommended dose and LC50 at 24 h were determined. Shortest LT50 was observed for fenthion (0.37 h) whereas longest LT50 from spinetoram (13.56 h). LC50 at 24 h was lowest in Abamectin (0.0052 ppm) followed by Emamectin benzoate (0.0084 ppm). Cartap hydrochloride significantly inhibited hatchability of 1, 2, 3, 4 day-old eggs (95.7, 94.0, 94.2, 89.8 % respectivly). Our result indicated that cartap hydrochloride was effective against both neonate and eggs of PTM.

Nitric oxide (NO) is an immune mediator in several insects. In addition, eicosanoids mediate various immune responses in response to microbial challenges. This study focuses on cross-talk between two immune mediators. Nitric oxide synthase (SeNOS) of Spodoptera exigua was predicted in its cDNA sequence by interrogation to the transcriptomes and validated by RT-PCR against developmental stage and larval tissues. RNA interference (RNAi) of SeNOS suppressed nodule formation of S. exigua larvae against heat-killed Xenorhabdus hominickii. RNAi of SeNOS also suppressed NO levels in fat body and hemocytes along with suppression of PLA2 activity. NOS-specific inhibitor, L-NAME, also inhibited PLA2 activity, but its enantiomer, D-NAME, did not. However, PLA2 of dexamethasone or oxindole did not suppress NO levels in the immune tissues. In addition, X hominickii did not inhibit up-regulation of NO levels. These results suggest that NO signal activates PLA2 to produce eicosanoids to mediate immune responses

Reactive oxygen species (ROS) induces oxidation against various biomolecules including fatty acids. Calcium-independent cellular phospholipase A2 (iPLA2) has been known to function maintenance of fatty acids in phospholipids in mammals. An insect iPLA2 (Pi-iPLA2) was predicted from transciptomes of the Indianmeal moth, Plodia interpunctella. It was expressed in all developmental stages from egg to adult. RNA interference (RNAi) against Pi-iPLA2 was performed with specific double-stranded RNA (dsRNA) with more than 70% efficiency in reduction of its expression. Under this RNAi condition, P. interpuctella exhibited developmental retardation with significant accumulation of lipid peroxidation measured by the amount of melondialdehyde

Phospholipase A2 (PLA2) hydrolyzes phospholipids at sn-2 position to release free fatty acids. PLA2 consists of a superfamily mainly categorized as secretory PLA2 (sPLA2), cellular Ca 2+ -dependent PLA2 (cPLA2), and cellular Ca 2+ -independent PLA2 (iPLA2). We are the first to report iPLA2 in insect. Here an objective of our study is to purify a recombinant iPLA2 protein (SeiPLA2) of Spodoptera exigua using bacterial expression system. An open reading frame of SeiPLA2 was cloned into an expression vector and then transformed into Escherichia coli BL21. Over-expression with IPTG yielded recombinant SeiPLA2 (rSeiPLA2), which was then purified by an affinity chromatography using Ni-NTA column. The purified rSeiPLA2 gave significant PLA2 activity using a pyrene substrate. Its activity was inhibited by an iPLA2 specific inhibitor (BEL), but not by sPLA2 inhibitor (BPB) or cPLA2 inhibitor (MAFP

Swarming alates of termite Macrotermes sp. has been accepted as food among people of Benishangul Gumuz zone in west Ethiopia bordering with Sudan. The preference seems to be for the reproductive caste. We assessed the nutritional composition of nymph and alate of Macrotermes sp. of Ethiopia. The adult contained higher amino acids (31%) compared to nymph (21%). However, the distribution of amino acids in the protein was similar (ap. 4:6 essential to non-essential amino acids). Both stages tend to have high fat contents (50%). Fat supplement could be a possible reason behind the human consumption of termites. Beside the bio-prospection of termite as food or oil source, termite foraging would have important evolutionary biology due to their significant amount of energy-yielding nutrients which could presumably be critical resource for development of larger brained hominines.

남한에 분포하는 우리딱정벌레류는 현재까지 총 6종 20아종이 알려져 있다(Imura et Kezuka, 1992; Park et al., 2013; Rapuzzi, 2015). 우리딱정벌레류의 분류는 수컷의 aedeagus 형태가 중요하게 다루어지고 있다(Kwon et Lee, 1984; Imura, 1997; Rapuzzi, 2015). 그러나 우리딱정벌레류를 포함한 몇몇 딱정벌레아과의 종들은 외부 특징으로 구별하는 것이 거의 불가능하며(Janovska et al, 2013), aedeagus의 형태로 명확한 구분이 어려운 종들이 있다(Kwon et Lee, 1984). 최근 이러한 분류군에서 inflated endophallus의 구조의 연구는 많은 분류학적 문제를 해결하고 있다(Brinev, 2002; Anichtchenko, 2004; Janovska et al, 2013). 국내에서는 Kwon et Lee, 1984에서 처음으로 딱정벌레아과의 endophallus 에 대한 연구가 있었으나 최근까지도 inflated endophallus의 구조에 대한 연구는 부족한 실정이다. 본 연구에서는 남한지역에 분포하는 우리딱정벌레속 6종을 대상으로 inflated endophallus의 형태를 확인하였으며, 그 결과 종간에 endophallus의 형태가 큰 차이가 있음을 확인하였다
