The fall armyworm (FAW), Spodoptera frugiperda, is an invasive pest species in Africa and Asia, which is native to the Western hemisphere. Invaded FAW was corn feeding strain. We study the developmental and biology of the corn strain FAW on the rice plants compare the result with corn feeding up to F2- generation. The development periods of F0, F1 and F2 generations of the rice-fed colony were 21.7%, 18.3% and 18.9% longer than corn-fed colony. The rice-fed colony was significantly lower in the body weight of larvae and pupae, and pre-adult survival rate and the fecundity than corn-fed colony. Our results showed that the corn strain FAW can survive and complete its life cycle by feeding rice plants up to several generations under laboratory condition, but their development and fecundity were reduced in comparison to the corn feeding colony. However, this study suggests potential impact of invaded FAW to the infestation of rice fields in Asian countries.

Palaclemensia is a genus within the family Incurvariidae, and it has been reported to be a monophagous or narrow oligophagous genus, like other incurvariids, except for two polyphagous species, Paraclemensia incerta and P. acerifoliella. Paraclemensia incerta is one of the common species in Japan and Korea, and seven host plant families are recognized. However, these host records aren’t based on DNA analysis or detailed morphological comparison. Therefore, it was hypothesized that there is genetic differentiation among host races in P. incerta. To investigate this hypothesis, DNA analysis and morphological comparison were performed on Paraclemensia species collected from Japan. As a result, genetic divergence among populations feeding different host plants was not confirmed. Moreover, not only P. incerta but also P. caerulea were suggested to be polyphagous. In contrast, geographic genetic divergence in P. incerta and P. caerulea was observed in Japan. Additionally, it is suggested that P. viridis, P. oligospina, and P. cyanea, despite external morphological differences, could be the same species.

Microbes in insect gut significantly influence host physiology. While Lepidoptera is a diverse insect order, the relationship between microbial symbiosis and host development remains elusive, especially concerning role of gut-colonizing bacteria in metamorphosis. We investigated the gut microbial diversity in Galleria mellonella throughout its life cycle using 16S rRNA amplicon sequencing. Our findings revealed a predominance of Enterococcus spp. in larvae and Enterobacter spp. in pupae. Remarkably, removing Enterococcus spp. hastened the larval-to-pupal transition. Transcriptome analysis showed an upregulation of immune response genes in pupae and hormone genes in larvae. Notably, the production of antimicrobial peptides in the host gut varied with developmental stages. Some of these peptides suppressed the growth of Enterococcus innesii, a dominant gut bacterium in G. mellonella larvae. This research underscores the pivotal role of gut microbiota shifts in metamorphosis, driven by the secretion of antimicrobial peptides in the G. mellonella digestive system.

The cucumber flower does’t seem to be supplying enough nectar and pollen to the natural enemies. Among the natural enemies that can be used in the cucumber greenhouse, especially Orius laevigatus may require flower nectar and pollen for settlement and reproduction. In our previous study, we selected basil as a natural enemy banker plant. Using this, the effect of thrips control in cucumber greenhouse was examined. The major pests of cucumber in 2023 were Aphis gossypii, Frankliniella occidentalis, Thrips palmi and Trialeurodes vaporariorum. A. gossypii occurred most frequently, and the next occurred pests were F. occidentalis and T. palmi. The densities of O. laevigatus remained stable on basil banker plants. After releasing O. laevigatus and adding the basil banker plants, the densities of T. palmi were kept low at less than 3 per leaf, and the densities of F. occidentalis were kept low at less than 10 per 3 flowers but increased slightly since late May. As a result, the density of thrips during cucumber cultivation was effectively suppressed after the use of natural enemies.

Root-knot nematode (RKN), Meloidogyne incognita, inflicts significant greenhouse crop damage, causing over 40% economic losses. While chemical agents effectively control RKN, they leave harmful residue in soil and crops. To address this issue, we investigated soil-derived entomopathogenic fungi (EPF) in this study. We assessed the nematicidal impact of ten EPF species through in vivo and in vitro tests. Beauveria bassiana JEF-503 exhibited nematicidal effectiveness exceeding 65% in both experimental settings. In a semi-field test using greenhouse pots, we experimented with the application of B. bassiana JEF-503 suspension during tomato growth, which is an uncommon practice in comparison to chemical treatments due to residue concerns. B. bassiana JEF-503 was applied during transplantation, and the same application was repeated four weeks later. JEF-503 One-time and abamectin treatments were used as control groups. The JEF-503 two-time application notably reduced root damage compared to single JEF-503 or abamectin treatment. In conclusion, JEF-503 offers a promising, residue-free, and environmentally friendly alternative to chemical agents for RKN management.

Feltiella acarisuga(Vallot) is a common gall midge that feeds on many species of spider mites. The effect of temperature and humidity on the development of F. acarisuga female were determined using eggs of the twos potted spider mite, Tetranychus urticae(Koch), as prey under laboratory condition (27.9±0.5℃, 90% RH, and 14:10 [L:D] h). F. acarisuga female laid the most eggs on the 5th day after mating, and the acumulative fecundity reached it speak on the 13th day. The sex ratio of F. acarisuga was 6:4, male to female. The average number of eggs per day during life was 2.7 but during the egg-laying period was 3.1. The female’s lifespan was about 3.5 days longer than that of the male in the adult stage but 6.2 days longer including the egg and larval period. The temperature did not affect the female survival and fecundity, but as humidity was lowered, the female’s survival period washortened and fecundity decreased. When using F. acarisuga as natural enemies, the optimal temperature rage was 20 to 30℃ and the relative humidity was 80 to 95%.

In moths, mating behavior is induced by sex pheromones released by the female being recognized by the males’s chemosensory systems. In this study, to understand the recognition of sex pheromones in Maruca vitrata, chemosensory genes were identified via transcriptome analysis of male and female antennae and heads. Approximately, 11.1Gb, 10.8Gb, 12.1Gb, and 11.6Gb of data were obtained from the antennae and heads of the male and female, respectively. Thirty-seven odorant binding proteins (OBPs), 21 chemosensory proteins, 7 sensory neuron membrane proteins, 102 odorant receptors (ORs), 36 ionotropic receptors, and 39 gustatory Receptors were identified as chemosensory genes from the M. vitrata. Among these genes, 5 OBPs and 4 ORs were specifically expressed in male antennae. These genes are likely to be involved in the sex pheromone recognition of M. vitrata.

Golden apple snails(GAS) are native to warm regions such as Central and South America and Southeast Asia, and were first introduced as a high-protein food. GAS are omnivorous and have a habit of eating plants submerged in water, so they have been used for eco-friendly weed control in rice fields since 1992. When the GAS was first introduced, it was thought that it would be impossible to overwinter in Korea. However after 2000, overwintering individuals were founded and damage to rice occurred and the development of means to control GAS has been required. In this study, we tested the effectiveness of an eco-friendly pest control agent using Styrax japonicus that grow naturally in Korea. As a result of exposing GAS to S. japonicus fruit powder, a 100% molluscicidal effect was confirmed at 66.7ppm. To investigate the duration of effect, treatment was performed at the same concentration and molluscicidal effect of more than 90% was up to 3 days after treatment. The killing effect of each part of the S. japonicus was compared, and the seed extracts showed no killing effect at all concentrations, while the sarcocarp extracts showed a 100% killing effect up to 33.3ppm, and the fruit extracts showed a 100% killing effect up to 200ppm.

Bemisia tabaci is a polyphagous pest that transmits various viruses, including tomato yellow leaf curl virus (TYLCV) while feeding on crops. Prior to identifying attractants of B. tabaci, the pheromone biosynthesis activating neuropeptide (PBAN) sequence was obtained via transcriptome analysis of female adults. After injecting artificially synthesized PBAN into the female adults, the compounds contained in the female adults were extracted using hexane, and gas chromatography-mass spectrometry (GC-MS) was performed. As a result, 22 compounds showed quantitative differences after PBAN injection. Among them, it was confirmed that B. tabaci is attracted to 2-ethylhexanoic acid and phytol. These results suggest that 2-ethylhexanoic acid and phytol can be used as attractants for the control of B. tabaci.

Sweet pepper(paprika) belongs to the genus Capsicum, and is one of the most important export product from Korea to Japan and Southeast Asia. So it is important to eradicate plant quarantine pests before export sweet pepper. Aphids, whiteflies and mites are major pests that can damage to sweet peppers. Fumigation is normally used to eradicate pests in plant quarantine, but phytotoxicity may can be appeared that affect the quality of the product. Low-temperature treatment, one of the most popular physical treatment, can reduce crop damage to preserve product quality, but it takes long time to kill pests, which can cause quality degradation. In this study, phytotoxicity of fumigants, phosphine(PH3), ethyl formate(EF) and PH3+EF on sweet peppers was investigated to use as basic data for physicochemical treatment. When treated with more than 35 mg/L of EF, phytotoxicity was occurred, and was not occurred with PH3. When low-temperature of 1.7 degrees treated for 15 days after fumigation, it seems to be no direct damage from low-temperature treatment. But quality of top of sweet pepper was decreased from 7 days after fumigation.

생활권 수목이란 주민들이 생활하는 지역에 식재된 수목으로, 가로수, 학교수목, 아파트 수목 등 종류가 다양 하며 도시경관과 생활환경 개선의 이점을 제공한다. 그러므로 생활권 수목의 유지와 관리에 있어서도 인근 주민 에 혐오감이나 피해가 없도록 방제를 수행하는 것이 매우 중요하다. 일반적인 경엽살포의 경우, 약액 비산에 의해 주민들의 활동 제한, 안전사고 및 재산상 피해가 발생할 수 있으므로 사용이 제한적이다. 이러한 문제를 해결하기 위해, 나무에 약제를 직접 주입하는 나무주사(trunk injection)가 보편적인 생활권 수목 방제법으로 주목 받고 있으며, 이는 주입물질의 손실이 없고, 외부환경에 크게 영향 받지 않는다는 장점이 있다. 하지만 생활권 수목 전반에 대한 나무주사 처리방법이 명확하지 않아 약효가 일부 가지에서만 나타나는 등 사후 검증 및 관리가 미흡한 실정이다. 본 연구는 생활권 수목 병해충 방제 나무주사 제품의 효과제고를 위한 기존 처리방법 개선 및 최적의 약제처리 방법을 검증하였다. 느티나무외줄면충(Colopha moriokaensis)을 대상으로 시험을 진행하였 으며, Acetamiprid을 시험약제로 사용하였다. 느티나무에 대하여 약제처리 위치, 주입량, 천공수, 주사시기에 따른 약효 및 약해를 확인하였으며, 이를 바탕으로 최적의 약제처리 방법을 제시하였다.

Drosophila suzukii (Diptera, Drosophilidae) can damage thin-skinned fruits (plums, cherries, peaches, blueberries, and strawberries) by laying eggs inside the fruit. In this study, a basic experiment was conducted to investigate the preference of D. suzukii to export table grape varieties. Four varieties of grapes (Kyoho grape, Shine muscat, Campbell grape, and Black sapphire) were placed in a cage containing more than 2,500 number of D. suzukii adults for 6, 8, 10, 12, and 24 hours and the egg-laying in grape has been induced. After 2 weeks, the number of pupae that emerged was counted. As a result, the largest number of pupae was generated in Kyoho grape among the four types of grapes, indicating that D. suzukii prefers to lay egg in Kyoho grape. Through this experiment, it was determined that 6 h was the appropriate inoculation time, and then an inoculation experiment was conducted on Kyoho grape. The total weight of the Kyoho grape used in the experiment was 36.119 kg, and a total of 2594 pupae were generated. The average number of D. suzukii per cluster was about 50. All stages of D. suzukii treated with low temperature(1℃) for 10 days were completely controlled.

매년 국내로 비래해 오는 해충인 벼멸구는 그 기원이 중국 또는 중국 남부일 것으로 예상해왔으나, 이에 대한 유전학적 근거는 Mun et al. (1999)에 의해 제시된 세 가지 COI haplotype 비교가 유일하다. Mun et al. (1999)은 국내에 서 확인된 두 가지 haplotype 유형이 인도차이나반도 이남의 균일한 한 가지 haplotype 집단 유형과 중국에서 확인 된 또 다른 haplotype 집단 유형임을 근거로 국내 벼멸구의 기원을 중국으로 특정한 바 있다. 본 연구는 국내 및 동남아시아 5개국(부탄, 미얀마, 캄보디아, 라오스 및 태국)으로부터 직간접적으로 확보한 개체들을 대상으로 GBS (genotyping by sequencing) 및 NGS 기법을 통해 PCA를 포함한 다양한 집단유전학적 분석을 수행하였다. 그 결과 인도차이나반도의 벼멸구 집단은 크게 북부와 남부로 나뉘며, 국내 개체들은 북부에 비해 남부(캄보디 아, 태국)에 더 가깝다는 사실을 확인하였다. 따라서 벼멸구의 국내 비래는 중국으로부터의 기원 이전에 장마전 선이 형성될 무렵부터 인도차이나반도 남쪽의 고온다습한 서풍이 남남서풍으로 바뀌면서 중국 내륙을 거쳐 국내로 비래하는 경로를 따르는 것으로 보인다. 하지만 태안의 개체 중에는 인도차이나반도 집단들의 외군으로 확인되는 개체가 있었고, 이는 인도차이나반도 외의 샘플링되지 않은 다른 지역에서도 벼멸구가 국내로 비래할 수 있다는 가능성을 제시하였다. 따라서 국내로 유입되는 벼멸구의 유전적 기원을 확인하기 위해서는 인도차이 나반도 남쪽 지역에서 시작한 동아시아 여름 몬순의 바람이 한국으로 도착하는 경로에 위치한 다른 지역에서의 추가적인 샘플링 및 지속적인 관심과 추적이 필요할 것이다.
