We evaluate possible interactions between three parasitoid species, the native Telenomus nizwaensis and the imported Trichogramma brassicae and Trichogramma evanescens, when presented with Deudorix livia host eggs under high-density laboratory conditions. Deudorix livia is a butterfly which is an economically damaging pest in the Omani pomegranate agro-ecosystem. Most (73.5% overall) of the observed parasitism was by T. nizwaensis. It performed best when presented with host eggs in the absence of either of the Trichogramma species. These imported species thus have some potential to disrupt suppression of the pest by the indigenous natural enemy under lower-density conditions in the field, and neither of them achieved high parasitism rates themselves (laboratory conditions: T. brassicae = 12.5%; T. evanescens = 18.5%; with no evidence for any parasitism of field-collected eggs). Future efforts in this agro-ecosystem would best be directed towards encouraging T. nizwaensis, rather than towards importation of Trichogramma. Screening for negative effects of natural enemies on the pest suppression provided by other natural enemies is recommended.","PeriodicalId":16736,"journal":{"name":"Journal of Pest Science","volume":"11 1","pages":""},"PeriodicalIF":4.8,"publicationDate":"2024-07-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141769071","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Lavender oil, derived from Lavandula angustifolia, was chosen as the plant-based material. The microcapsules’ morphology and the fabric’s surface were examined using optical and scanning electron microscopes. Dynamic light scattering was utilized to measure the capsule size and zeta potential. The mosquito repellent efficacy was evaluated through cage tests before and after multiple wash cycles and after exposure to different environments. A cytotoxicity assay was conducted on functionalized fabrics in order to assess their biocompatibility. Additionally, comfort properties such as breathability and water absorbency were assessed and compared to a control fabric. The results indicated that a higher concentration of lavender oil microcapsules (15 wt%) on the fabric exhibited excellent mosquito repellent efficacy (95.7%) prior to washing, which remained effective as 84.5% even after 40 washes. Furthermore, the functionalized fabric maintained its repellent properties following exposure to temperatures of 25 °C and 37 °C for 4 weeks. The cytotoxicity results indicated that the functionalized fabric exhibited non-toxic properties toward L929 cells, thereby confirming its favorable biocompatibility. This study successfully demonstrated the synthesis and application of silk-based lavender oil microcapsules on textiles, resulting in highly durable mosquito repellent fabrics effective against Aedes aegypti mosquitoes. These findings highlight the potential of this eco-friendly approach for developing effective and long-lasting mosquito repellent textiles.","PeriodicalId":16736,"journal":{"name":"Journal of Pest Science","volume":"28 1","pages":""},"PeriodicalIF":4.8,"publicationDate":"2024-07-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141755266","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Endophytic colonization and relative expression of plant defense genes were tracked using molecular techniques alongside evaluation of antibiosis effects on S. littoralis and plant tolerance to larval-induced leaf injuries. Inoculated plants exhibited antibiosis and potential growth compensation in responses to various S. littoralis challenges, which resulted in increased fresh and dry weight, chlorophyll content, number of secondary branches and stem diameter. Furthermore, up-regulation in the relative expression of ethylene (ACO1, ACO3, EIN2, EIN3) and jasmonic acid (LOX2)-related genes were observed, with the endophytic B. bassiana- induction of ethylene and jasmonic acid production being higher in S. littoralis infested plants.

Known pyrethroid resistance-associated point mutations within the voltage-gated sodium channel were undetected in the cDNA and gDNA of resistant strains or field populations. The whole-genome de novo assembly of a Korean-resistant strain was performed (GCA_026262555.1), and 13 genomes of susceptible and resistant individuals were re-sequenced using field populations. Approximately 3,369,837 variants (SNPs and indels) were compared with our reference H. armigera genome, and 1,032,689 variants were identified from open reading frames. A resistance-specific CYP3 subfamily gene with five variants (CYP321A1v1–v5) was identified in the resistant strains, indicating the potential role of these variants in resistance. RNA-seq analysis identified 36,720 transcripts from 45 Illumina RNA-seq datasets of the fatbody, gut, and the rest of the body. Differential gene expression analysis revealed some differently overexpressed detoxification enzyme genes in the resistant strains, particularly cytochrome P450 genes. This finding was consistent with the results of bioassay tests using PBO-based synergists that inhibit enzymes belong to cytochrome P450 family, further supporting the role of detoxification enzymes in resistance. Therefore, H. armigera may acquire deltamethrin resistance through a combination of actions, including the overexpression of various detoxification enzymes, such as CYP321A5 identified in this study may serve as a basis for understanding insecticide resistance at the molecular level and can be applied as diagnostic markers for resistance.","PeriodicalId":16736,"journal":{"name":"Journal of Pest Science","volume":"31 1","pages":""},"PeriodicalIF":4.8,"publicationDate":"2024-07-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141726257","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In addition to sex-biased gene expression networks, these traits often involve variations in hormone levels. Juvenile hormone (JH), which is synthesized by corpora allata (CA), regulates development and reproduction in insects. However, there is limited understanding regarding sex-biased gene expression in CA and the sexually dimorphic functions of JH. We discovered sexual dimorphism in JH levels in cockroaches. To explore the underlying mechanism, we analyzed RNA-sequencing data from CA tissues in the adult females and males of the American cockroach, Periplaneta americana. Our investigation revealed significant variation in sex-biased gene expression, with female-biased genes primarily involved in cytochrome P450, glutathione S-transferase and peroxidase pathways, associating with resistance to environmental stress. Notably, exposure to the insecticide imidacloprid, injection of Escherichia coli and H2O2 led to a higher mortality rate in males, whereas females exhibited resistance. Importantly, the application of the JH analog methoprene following the injection of E. coli and H2O2 rescued survival and the expression of stress response-related genes in males. Furthermore, these stressors resulted in reduced JH biosynthesis in males, while females remained unaffected. In summary, our results reveal that sexually dimorphic JH levels and gene expression modulate stress responses in P. americana. These findings shed light on sex-specific responses to environmental stress, offering tailored strategies for pest control based on gender.","PeriodicalId":16736,"journal":{"name":"Journal of Pest Science","volume":"19 1","pages":""},"PeriodicalIF":4.8,"publicationDate":"2024-07-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141726258","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

For larval identification, the mitochondrial gene cytochrome c oxidase I (COXI) was amplified by polymerase chain reaction (PCR). Fungal isolates from wood and insects collected from the sampled oaks were identified by morphology, acid production on creatine sucrose agar (CREA) medium, phylogeny of DNA sequence data for the β-tubulin gene and the internal transcribed spacer (ITS) rDNA. To detect P. formosus in larvae and adult insects, we used a nested PCR assay with the species-specific primer pairs PaMF and PaMR. The insects that most often tested positive for P. formosus were larvae of the buprestids Acmaeodera sp. and Chrysobothris affinis, and larvae of the cerambycid Trichoferus campestris. Adults of C. affinis and Calchaenesthes diversicolis (Cerambycidae), which were collected from within their galleries, also tested positive. Beetle larvae of Anthaxia sp.

This review summarizes current research, examining the spectrum of VOC-mediated plant defense priming in terms of anti-herbivore or anti-pathogen properties, the cost–benefit implications for plants, and the influence of abiotic factors on the priming. Additionally, we explore two promising approaches within the framework of Integrated Pest Management (IPM): the implementation of companion sentinel intercropping and the application of synthetic VOCs.

Plant peptides may represent a more environmentally-friendly tool to manage olive fly, due to their recognized role to activate and/or prime plant defence responses against pests. In this work, behavioural experiments (no-choice and two-choice) and analysis of volatile compounds were carried out to evaluate the impact of the exogenous application of the peptide systemin to olive tree on olive fly infestation, and to elucidate its mode of action to prime plant defence. The treatment of olive branches with 10 nM systemin showed to confer protection against olive fly, by reducing significantly the ovipositions (up to 3.0-fold) and the number of infested fruits (up to 2.9-fold) when compared to non-treated branches. This protective effect was even detected in neighbouring non-treated branches, suggesting the ability of systemin to trigger plant-to-plant communication. The deterrent activity of the primed olives was associated with the emission of the volatiles 2-ethyl-1-hexanol, 4-tert-butylcyclohexyl acetate and 1, 2, 3-trimethyl-benzene, which were negatively correlated with oviposition and fly infestation. Systemin has also showed to trigger the biosynthesis of specific volatiles (esters) in olives in response to fly attacks. Overall, the observed protection conferred by systemin against olive fly is likely due to the emission of specific volatiles that can act as a defence and/or as signalling molecules to upregulate the plant defence response. Thus, systemin represents a novel and useful tool to manage olive fruit fly.","PeriodicalId":16736,"journal":{"name":"Journal of Pest Science","volume":"17 1","pages":""},"PeriodicalIF":4.8,"publicationDate":"2024-07-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141556771","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, biological control of this pest on tomato is often difficult because the plant’s glandular trichomes release substances that are toxic to arthropods and hinder the foraging of natural enemies. Therefore, adaptation of natural enemies to this crop is one of the selection criteria for potential biocontrol agents. We collected predatory mites from wild and feral tomato plants and found the species Amblyseius herbicolus and A. tamatavensis. Whereas the latter is known to feed on B. tabaci eggs, we investigated the ability of A. herbicolus to develop and reproduce when feeding on this prey stage, and assessed whether both species can feed and develop on B. tabaci crawlers. To verify the adaptation of these predators to tomato, we assessed their ability to disperse on tomato plants and their establishment on clean tomato plants with pollen as an alternative food. Finally, we evaluated whether the predators were effective in controlling B. tabaci on tomato plants with different pollen dosages as alternative food. We show that both predators fed and reproduced on B. tabaci immatures. A. herbicolus established and dispersed better on tomato plants supplemented with cattail pollen than A. tamatavensis and only A. herbicolus was able to control B. tabaci in two population dynamics experiments. Our results suggest that A. herbicolus is better adapted to tomato than A. tamatavensis and may therefore be a promising biocontrol agent on tomato.","PeriodicalId":16736,"journal":{"name":"Journal of Pest Science","volume":"25 1","pages":""},"PeriodicalIF":4.8,"publicationDate":"2024-07-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141553339","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
