While nucleopolyhedrovirus (NPVs) and Bacillus thuringiensis (Bt) Berliner (Bacillales: Bacillaceae) have been widely used as microbial insecticides, their combined effects against A. ipsilon remain poorly understood. This study evaluated the pathogenicity of different NPVs and Bt strains against A. ipsilon larvae, both individually and in combination. Pathogenicity varied significantly among treatments, with Mamestra brassicae multiple nucleopolyhedrovirus (MbMNPV) exhibiting the highest virulence, causing 84.62% insect mortality at the lowest tested concentration (1 × 105 OBs/ml). Insect mortality generally increased with higher NPVs concentrations, reaching over 90% at 1 × 108 OBs/ml. In contrast, Spodoptera litura (Fabricius) multiple nucleopolyhedrovirus (SlMNPV) showed moderate lethality compared to MbMNPV, while Spodoptera exigua (Hübner) multiple nucleopolyhedrovirus (SeMNPV) and 2 Bt strains exhibited even lower pathogenicity. The interactions between NPVs and Bt varied depending on pathogen combinations and concentrations. Synergistic effects were observed in SlMNPV-Bt mixtures, leading to increased larval mortality and distinct survival curves compared to treatments with SlMNPV or Bt alone. MbMNPV-Bt combinations produced stable additive effects in most cases, whereas SeMNPV-Bt combinations exhibited varied effects, including synergistic, antagonistic, and additive effects. These findings provide insights into optimizing NPV-Bt combinations for A. ipsilon control, offering a potential alternative to chemical insecticides.","PeriodicalId":94077,"journal":{"name":"Journal of economic entomology","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-09-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145126951","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The rearing process requires feeding honey bee (Hymenoptera: Apidae: Apis mellifera (Linnaeus, 1758))-collected multifloral pollen mixes to developing bumble bee colonies. Honey bees and bumble bees, however, preferentially forage on pollens with different nutritional profiles to meet different nutritional needs. Therefore, developing supplements to increase palatability and nutrition in pollen diets for these managed bumble bee colonies may better meet their needs. Oyster mushroom (Pleurotus spp.) mycelium is an abundant, renewable, and nutritional resource, making it a promising candidate for such supplements. We evaluated the influences of oyster mushroom mycelium-augmented pollen on bumble bee development and colony growth. We hypothesized that: (i) microcolonies provided with mycelium-augmented pollen produce more offspring; and (ii) mycelium-augmented pollen provides a nutritional benefit to developing bumble bee larvae by increasing their fat content, weight, and body size. We established Bombus impatiens microcolonies and provided them with pollen provisions containing a 1% concentration of two species of oyster mushroom mycelium (Pleurotus columbinus (Agaricales: Pleurotaceae: Pleurotus ostreatus var. columbinus (Quél, 1886), or Pleurotus djamor (Agaricales: Pleurotaceae: Pleurotus djamor (Fries, 1821))) or a mycelium-free control. Microcolonies given P. columbinus-augmented pollen had more offspring with faster development times that were higher in weight and fat content than P. djamor and mycelium-free colonies. This suggests that P. columbinus mycelium has the potential to be a beneficial dietary additive to managed B. impatiens diets to increase colony success and offspring development.","PeriodicalId":94077,"journal":{"name":"Journal of economic entomology","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-09-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145115789","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Three common blueberry varieties ('Bluecrop,' 'Blueray,' and 'Elliott') were also examined to identify berry characteristics known to influence D. suzukii infestation.

Based on the combined degree-day model, monitoring traps should be deployed in early June, as the first detection of D. suzukii typically occurred in mid-June. Additionally, the model predicts that peak activity, marked by 50% of cumulative trap capture, will occur by late July. The late season 'Elliott' berries were more susceptible to infestation, while firmer berries had lower infestation rates, regardless of blueberry variety.

Their rapid geographic expansion and abundance of multiple vector species emphasize the need for systematic tick surveillance. Current tick surveillance efforts target the host-seeking phase, even though ticks spend most of their life in the upper soil in a quiescent state. In an effort to expand the existing tick surveillance strategies, a novel molecular approach was developed for the detection, identification, and relative quantification of tick DNA in soil samples. Amblyomma americanum Linnaeus, Ixodes scapularis Say, Rhipicephalus annulatus Say, and R. sanguineus Latreille (Ixodida: Ixodidae), all species of medical and veterinary health importance, were employed for protocol optimization. Ticks (individual or pooled) from all life stages were spiked in soil, and DNA was extracted using a verified protocol adapted for arthropods. Tick DNA was detected with multiplex Polymerase Chain Reaction (PCR) using novel species-specific primers designed based on sequence dissimilarities at the ribosomal RNA gene cluster (5.8S-ITS2-28S rRNA genes) so that the PCR products for each species would be distinguishable by size in gel electrophoresis. Individual target species were successfully detected and identified from soil, while in pooled samples, all 4 species were clearly distinguishable. Detection sensitivity was as low as 5 eggs/40 ml of soil. Specificity tests revealed the absence of cross-reaction between species-specific primers and nontarget species. This approach could provide a robust, standardized, and cost-efficient technique for tick detection in locations of putative tick abundance, complementing existing surveillance methods and facilitating control interventions.","PeriodicalId":94077,"journal":{"name":"Journal of economic entomology","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-09-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145093345","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study combined field observations and simulated datasets to assess whether the resilience of pollination exists in agricultural ecosystems and to what extent it can maintain crop pollination. Fourteen squash (Cucurbita pepo L.) fields along a gradient of semi-natural habitats were selected in Kunming, Yunnan Province, China. Pollinator abundance and visitation density were sampled in 2020 and 2021. The resilience of pollination was quantified as the increase in pollen deposition by honey bees following experimental exclusion of bumble bees. Codes were developed to simulate the amount of pollen grains deposited by honey bees and bumble bees respectively. Results showed that bumble bee abundance increased significantly with semi-natural habitats, while honey bee abundance remained stable. Bumble bee exclusion resulted in a significant increase in honey bee visitation density. The proportion of semi-natural habitats significantly positively influenced the resilience of pollination. Furthermore, the resilience of pollination maintained squash pollination to 1,200 pollen grains per flower, thereby securing squash pollination. In conclusion, semi-natural habitats can enhance the resilience of squash pollination at an acceptable level in agricultural landscapes.","PeriodicalId":94077,"journal":{"name":"Journal of economic entomology","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-09-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145093347","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Notably, CYP450 significantly affects trehalose metabolism of Tribolium castaneum (Herbst) (Coleoptera: Tenebrionidae), a devastating stored pest. To explore whether trehalose enhances CYP gene responses to CO2 stress, investigations were conducted on the 95% CO2 tolerance in 8th-instar T. castaneum larvae, whose specific CYP genes-TcCYP4BN1, TcCYP9F2, and TcCYP9AB1-were silenced, across different trehalose dietary regimes (50% flour + 50% trehalose or 100% trehalose). The 95% CO2 tolerance response was systematically evaluated through multi-dimensional analysis of gene expression levels, carbohydrate contents, and enzyme activities. Results indicated that compared with the 50% flour + 50% trehalose feeding regimen, trehalose-only diet groups exhibited downregulation of trehalose metabolism-related genes, with the notable exception of the dsCYP9F2 experimental group. As to carbohydrate contents, glucose content increased significantly on 100% trehalose diet by inhibiting the expression of TcCYP9AB1, but it decreased in the other 2 groups, a pattern that also held true for glycogen. Together, these results demonstrate that trehalose does enhance the response of CYP genes to CO2 stress, and that TcCYP9AB1 is more responsible for modulating trehalose metabolism. Future research could investigate the molecular mechanisms underlying these regulatory processes and their practical applications, potentially enhancing biocontrol techniques and advancing pest management solutions.","PeriodicalId":94077,"journal":{"name":"Journal of economic entomology","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-09-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145093359","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this study, we investigated the bacterial community composition and functional profiles in the SLF gut, TOH leaves, and TOH rhizosphere soil using amplicon and metagenomic sequencing. This study showed that the bacterial alpha-diversity differed significantly among the 3 sample types (P < 0.05). Venn analysis identified 4 shared amplicon sequence variants (ASVs) between the TOH rhizosphere soil and SLF gut, suggesting potential bacterial interactions or transfer. Further source-tracking analysis indicated that most gut bacteria originated from the rhizosphere soil. However, the dominant taxa varied across compartments: Proteobacteria dominated both the SLF gut and TOH leaves, while Acidobacteria predominated in the TOH rhizosphere soil. Network analysis revealed significant correlations between gut and rhizosphere microbes, notably Candidatus Vidania and Fastidiosipila (P < 0.05, r = 1). Functional profiling showed that the rhizosphere microbiome was enriched in nitrogen cycling and carbon fixation pathways, whereas the gut microbiome was associated with carbohydrate metabolism and nutrient assimilation. These results provide new insights into the potential roles of microbiomes in mediating plant-insect interactions and underscore the rhizosphere as a critical microbial source for SLF.

Both the flowers of B. ramiflora and their headspace extracts exhibited significant attractive effects on M. usitatus.

The antennae of M. usitatus demonstrate distinct sensitivities to different volatiles, with the appearance of their EAG response peaks being affected by the dosage levels at which these volatiles are applied.

Monitoring of adult flies over multiple years revealed R. mendax activity shifting approximately 3 wk earlier in the season at times when D. suzukii activity is low. Larval sampling in infested blueberry fields over 11 yr showed a similar changing pattern of activity. Berries collected from a multicultivar planting over 3 yr revealed that R. mendax laid eggs most often in ripening fruit and can even lay eggs in green fruit, indicating risk of infestation before D. suzukii infestation risk. Significantly more R. mendax were detected in later ripening cultivars than earlier cultivars, reflecting overlap between ripening stage and fly activity. When collected pupae were placed in non-overwintering conditions, approximately 1% emerged as adults within the first 57 d, showing that non-diapausing individuals have potential to also extend activity late in the season.

Flight intercept traps, including Lindgren funnel traps and cross-vane panel traps, are widely used in surveillance and monitoring programs for forest beetles. Their performance varies among species and the mechanisms underlying their function remain poorly understood. Previous research on trap design effects has predominantly relied on end-point assays, which fail to capture the behavioral processes driving trap performance and often result in oversimplified or teleological explanations, thereby limiting improvements in trap design. We developed and applied a simple 3-step model of trap function to understand the effects of trap design: (i) approach, where insects initiate directed movement toward the trap; (ii) capture, where contact with the trap results in either capture or escape; and (iii) retention, where captured insects remain in the trap or escape. Using observational experiments in the field, we investigated the behavioral responses of Monochamus spp. (Coleoptera: Cerambycidae) to intercept trap designs and collection cup treatments. Observation of beetle approaches to intercept traps revealed that a higher proportion of beetles progressed from 1 m to trap contact with panel traps compared to funnel traps, while escape rates from both wet and dry collection cup treatments were negligible. These findings highlight the importance of behavioral observations in improving our understanding of trap function and identifying features that enhance performance. By providing a mechanistic framework for insect-trap interactions, this work supports the development of more effective tools for monitoring insects.","PeriodicalId":94077,"journal":{"name":"Journal of economic entomology","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-09-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145093318","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
