Although varietal differences in susceptibility to codling moth infestation have been reported, substantial damage may occur under inadequate management practices. The recent establishment of this pest in the apple-growing regions of Jammu and Kashmir, India, has highlighted the need for a better understanding of varietal preference and the influence of weather parameters on pest population dynamics. The present study was conducted during 2021 and 2022 in the karewas of Nadihal village, Baramulla district, to assess the varietal preference of codling moth based on fruit damage and infestation levels, and to determine the relationship between pest incidence and key meteorological factors. Ten apple varieties-Red Delicious, American Apirouge, Sur Saharanpuri, Hazratbali, Maharaji, Chamoora, Rail, Kisri, Titu, and Condition-were evaluated at different fruit developmental stages on both fallen and on-tree fruits. Red Delicious consistently recorded the highest fruit damage and infestation, whereas American Apirouge was the least susceptible. Infestation increased progressively with fruit development, with the lowest levels observed during May (fruit development stage I). Late-maturing varieties generally suffered higher damage intensity. Correlation analysis showed a positive association between codling moth infestation and maximum and minimum temperatures, while rainfall and relative humidity (morning and evening) were negatively associated with pest incidence. These findings support the use of varietal selection and weather-based monitoring for developing effective integrated pest management strategies against codling moth.","PeriodicalId":11751,"journal":{"name":"Environmental Entomology","volume":"55 5","pages":""},"PeriodicalIF":1.8,"publicationDate":"2026-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149015873","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, surveillance of microbial pathogens in tropical wild bee communities remains severely limited. We investigated Nosema ceranae detection prevalence in the orchid bee Euglossa imperialis across seasons at 2 ecologically contrasting sites in the Panama Canal corridor: a protected tropical forest and a semi-urban landscape. Using species-specific polymerase chain reaction (PCR) assays, we detected N. ceranae DNA in gut tissues of this euglossine bee. Detection prevalence was significantly higher at the protected forest site (34/44; 77.3%) than at the semi-urban site (12/38; 31.6%), with no seasonal effect observed. A literature synthesis revealed that Nosema parasites have been reported across at least 9 hymenopteran families, with N. ceranae showing the broadest distribution of reported associations among named species, including detections in managed and wild bees as well as social wasps. This study provides the first molecular detection of N. ceranae in E. imperialis and indicates that N. ceranae DNA is detectable in wild pollinator communities at 2 ecologically contrasting sites in the Panama Canal corridor. The higher detection prevalence at the forest site suggests that local spatial or ecological context may be an important correlate of exposure in this system, a hypothesis that will require testing with additional replicated sites and environmental covariates. These findings highlight the need for expanded pathogen monitoring in Neotropical pollinator communities and underscore the importance of integrating ecological surveillance with molecular diagnostics to assess emerging pathogen risks in tropical ecosystems.","PeriodicalId":11751,"journal":{"name":"Environmental Entomology","volume":"55 5","pages":""},"PeriodicalIF":1.8,"publicationDate":"2026-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149165069","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Previous studies on its life parameters often used detached soybean leaves, which may not accurately reflect development and reproduction due to disrupted nutrient flow. This study compared survival, development, and reproduction of A. solani on living versus detached leaves at 19, 22, 25, 28, 31, and 34 °C. Between 19 and 28 °C, aphids developed and reproduced successfully on both leaf types. At 31 °C, nymphs failed to mature on detached leaves but reached adulthood on living leaves, though no nymphs were produced. At 19, 22, and 25 °C, fecundity and net reproductive rate were overestimated on detached leaves. At 28 and 31 °C, adult longevity, total longevity, oviposition day, fecundity, intrinsic and finite rates of increase, and net reproductive rate were underestimated on detached leaves. The mean developmental rate (y, reciprocal of nymph duration) on living leaves in relation to temperature (x) follows the equation y = 0.0088 x-0.0717. The lower developmental threshold is 8.15 °C, and the effective cumulative temperature required for nymph-to-adult development is 113.64 degree-days. On detached leaves, the equation y = 0.0055 x + 0.0043 yields an invalid threshold of -0.78 °C and 181.82 degree-days.

Current management relies heavily on insecticides, with limited options for organic or biological control. This study evaluated the overwintering survivability of Beauveria bassiana (Balsamo) Vuillemin (Hypocreales: Cordycipitaceae) spores on lanternfly egg masses to assess the feasibility of winter and spring, preemergence applications during vine dormancy. Laboratory bioassays suggested treatments of commercially available B. bassiana to spotted lanternfly egg masses resulted in infection of newly eclosed neonates. The optimal timing of spray applications on egg masses was approximately 2 wk before emergence. However, infection was also observed in newly emerged nymphs when treatments were applied even 20 wk before insect hatch. Treatments 20 wk before hatch significantly reduced the viability of conidial residues with wettable powder formulations exhibiting higher germination rates than oil-based formulations. These findings highlight the influence of environmental conditions on fungal spore persistence and underscore the potential for refining formulations and application timing to enhance biological control of spotted lanternfly. Two field trials demonstrated the applicability of mycoinsecticide treatments to overwintering spotted lanternfly egg masses. Both field trials demonstrated infection of hatching nymphs at levels greater than those observed in laboratory bioassays. This management approach would provide growers with a viable, low-toxicity, and Organic Materials Review Institute approved solution for managing spotted lanternfly months to weeks before the predicted hatch of spotted lanternfly.","PeriodicalId":11751,"journal":{"name":"Environmental Entomology","volume":"55 4","pages":""},"PeriodicalIF":1.8,"publicationDate":"2026-07-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148403847","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In the present study, surveys of egg parasitoids of the genus Trissolcus and 3 fruit-piercing stink bugs: H. halys, Plautia stali Scott (Hemiptera: Pentatomidae), and Glaucias subpunctatus (Walker) (Hemiptera: Pentatomidae), were conducted with sweep nets from 2018 to 2020 in Japan to clarify their species compositions. This method is independent of the type and condition of egg masses unlike the sentinel egg mass exposure method. Therefore, it is possible to capture the adult egg parasitoid assemblage associated with host habitats. Although a diverse composition of fruit-piercing stink bugs was observed depending on the sampling site, Trissolcus japonicus (Ashmead) (Hymenoptera: Scelionidae) was the dominant species in most areas. These areas contained a low percentage of H. halys and a high percentage of P. stali or G. subpunctatus. Trissolcus japonicus is considered the most important natural enemy of H. halys in its native region, as inferred from its preference results. However, it has often been observed that T. japonicus emerges from eggs of P. stali and G. subpunctatus in Japan, and the frequent collection of T. japonicus in habitats dominated by these stink bugs in this study is consistent with a relatively broad host range in the field. Therefore, further research is needed on the comprehensive relationship between T. japonicus and the available stink bug species, including H. halys, that can serve as hosts in their native regions.","PeriodicalId":11751,"journal":{"name":"Environmental Entomology","volume":"55 4","pages":""},"PeriodicalIF":1.8,"publicationDate":"2026-07-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148403857","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the abundance of floral resources changes throughout the season, potentially altering bee visitation rate per flower. This could affect pathogen transmission by influencing both the likelihood of pathogen deposition on flowers and of new hosts encountering pathogens. We assessed the effect of peak bloom timing on transmission of a bumble bee (Bombus impatiens Cresson) (Hymenoptera: Apidae) pathogen (Crithidia bombi Lipa & Triggiani) in a 2-wk tent experiment. We manipulated floral abundance using Monarda fistulosa L to provide more flowers either in the first week (early peak bloom) or second week (late peak bloom). Each tent received 1 infected (donor) and 1 uninfected (recipient) microcolony. We recorded floral visitation, and after 2 wk, assessed infection prevalence and intensity in both microcolonies. We found that peak bloom timing affected donor bee infection, but not transmission to recipient bees. Donor infection intensity was lower when bees had more flowers available early than late in the experiment. However, peak bloom timing did not affect the probability of infection in donor or recipient microcolonies, or the intensity of infection of recipient microcolonies. Furthermore, donor probability of infection and recipient infection intensity were positively related to inflorescence visitation rates in the second week. These results suggest that peak bloom timing could influence bee-pathogen dynamics by altering visitation rates per flower, highlighting the importance of phenological changes in plant-pollinator interactions for pollinator health.","PeriodicalId":11751,"journal":{"name":"Environmental Entomology","volume":"55 4","pages":""},"PeriodicalIF":1.8,"publicationDate":"2026-07-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148374937","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Despite the potential implications of this emerging threat, X. monographus remains poorly studied. The only in-depth account of its biology and ecology dates to 1964. Beyond that, references are scattered across gray literature, regional journals, and diverse linguistic sources, leaving researchers and land managers without a centralized foundation from which to respond to its spread in North America.

We consolidate all available information on X. monographus, including taxonomy, distribution, microbiome, life history, host associations, and ecological impacts. Across the literature, X. monographus emerges as a species likely adapted to detecting and exploiting weakened hosts in patchy landscapes with few tested management options.

Ant foraging can also influence the abundance of insect herbivores and their associated natural enemies. A 2-yr field experiment (2023-2024) was conducted to evaluate the effects of ant exclusion on pecan aphids (yellow pecan aphid complex and black pecan aphid) and their associated natural enemies (lady beetles, lacewings, and long-legged flies) at 3 canopy heights (upper, middle, and lower). Seasonal trends in aphid abundance were generally similar between treatments across both years, and on most sampling dates; no treatment effects were detected for aphids or aphidophagous predators. However, on specific sampling dates, aphid abundance was lower in ant-excluded trees, and peak ant activity coincided with the aphid activity, suggesting that the strength of ant-aphid interactions varies with aphid population density. In contrast, parasitized aphid mummies were significantly more abundant on control trees in 2023. It was found that lady beetle and lacewing activity was higher and coincided with the peak activity during July and August. Additionally, long-legged flies were more abundant in ant-excluded trees during 2023 and were influenced by canopy height in both years. Collectively, these results indicate that ant exclusion can influence aphid-natural enemy interactions in pecan orchards, but these effects are episodic, natural enemy-specific, and variable by growing season.","PeriodicalId":11751,"journal":{"name":"Environmental Entomology","volume":"55 4","pages":""},"PeriodicalIF":1.8,"publicationDate":"2026-07-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148701053","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
