(Lepidoptera: Noctuidae), is widely distributed throughout North and South America. It appears on important crop hosts with mixed populations of other looper species, especially the cabbage looper, Trichoplusia ni (Hübner) (Lepidoptera: Noctuidae). One of the earliest attempts to distinguish between the 2 species was to examine the legs of caterpillars, and those that possessed \"black\" legs were considered soybean loopers. However, it was demonstrated that this characteristic was variable and not under simple genetic expression. We examined 3 different environmental factors (temperature, light duration, and rearing density) to determine if these had an impact on the development of dark coloration on soybean looper legs. Larvae were exposed to 5 distinct levels of each environmental variable. We found that all 3 factors impacted the amount of dark coloration in the legs. Larvae reared at the coldest temperature and most light displayed darker-colored legs as early as the third instar of larval development. As larval rearing density increased, dark coloration on legs also increased, but this was not apparent until the fifth instar of larval development. There was a general trend for pupal weight to decrease and days to pupation to increase as the percentage of darkness on soybean loopers' legs increased within the various treatments of the study. Overall, dark leg coloration was largely dependent on environment and an apparent fitness cost was associated with larvae exhibiting darker legs within the various rearing conditions examined.","PeriodicalId":11751,"journal":{"name":"Environmental Entomology","volume":" ","pages":"565-573"},"PeriodicalIF":1.8,"publicationDate":"2025-06-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143729488","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}

The wavelet analysis revealed different patterns of population peaks between aphid species and their parasitoids. Aphids, such as Rhopalosiphum padi L., Sitobion avenae (Fabricius), Schizaphis graminum (Rondani), and Metopolophium dirhodum (Walker), showed varied peak frequencies, with M. dirhodum consistently exhibiting a shortening interval between outbreaks. In contrast, parasitoids maintained more-constant patterns, with peak frequencies predominantly around 12 mo. Cluster analysis identified 4 highly synchronized aphid-parasitoid pairs: S. graminum-Diaeretiella rapae (MacIntosh), R. padi-Aphidius platensis Brèthes, S. avenae-Aphidius uzbekistanicus Luzhetzki, and M. dirhodum-Aphidius rhopalosiphi De Stefani-Perez. The wavelet coherence (WC) showed significant correlations between the time series of these pairs, ranging from in-phase to anti-phase relationships over time. The results indicate that wavelet analysis is a viable tool for characterizing non-stationary time series, such as aphid and parasitoid populations. Understanding these dynamics and synchronization patterns can support integrated pest-management strategies, enabling more effective and sustainable agricultural interventions.","PeriodicalId":11751,"journal":{"name":"Environmental Entomology","volume":" ","pages":"644-653"},"PeriodicalIF":1.8,"publicationDate":"2025-06-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143996763","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}

The emerald ash borer (EAB), Agrilus planipennis Fairmaire (Coleoptera: Buprestidae), is an invasive pest of ash trees (Fraxinus spp.) within its introduced range. As adults, EAB must feed upon foliage to sexually mature. We compared the influence of 4 North American ash species on EAB via foliage feeding to assess impacts on female lifespan and reproductive metrics. We fed 136 female EAB, 34 in each foliage group, either black, green, tropical, or white ash throughout their adult life. We performed daily inspections for adult mortality, oviposition, and egg hatching. We found that the mean female lifespan, fertility rate, and mean egg development time were not affected by the ash species. Potential and realized fecundity each increased with summed female group lifespan (days), but this rate differed among ash species. Consequently, there was a statistically significant interaction effect of the summed female group lifespan and the host foliage. Green ash-fed EAB laid (2.94 ± 0.86 eggs/female days) and hatched (1.67 ± 0.59 eggs/female days) the most eggs, more than double the rates of EAB feeding on black (1.39 ± 0.48 laid and 0.75 ± 0.30 hatched eggs/female days) and white (1.08 ± 0.35 laid and 0.65 ± 0.22 hatched eggs/female days) ash. Adults feeding on green ash resulted in the greatest EAB fecundity suggesting that the presence of green ash may promote population growth and provide a pathway to overwhelm other ash species nearby.","PeriodicalId":11751,"journal":{"name":"Environmental Entomology","volume":" ","pages":"593-602"},"PeriodicalIF":1.8,"publicationDate":"2025-06-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12199364/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143968491","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Trees were protected from EAB colonization until 2012. We recorded current-year woodpecker holes and EAB adult exits on live trees annually from 2017 to 2022. Annual radial growth was quantified on increment cores from live trees and cross-sections from EAB-killed trees. Every Fraxinus nigra was killed by EAB by 2013. By August 2022, 63% of F. pennsylvanica, 12% of F. americana and 86% of F. chinensis trees had died. In contrast, F. quadrangulata trees were minimally colonized and remained healthy through 2022. Average (± SE) annual increment from 2007-2021 ranged from 2.65 ± 0.18 mm for F. quadrangulata to 4.61 ± 0.46 mm for F. chinensis. In an adjacent plantation planted in 2010, we assessed size, growth and EAB signs in 2022 on 12 live F. pennsylvanica and 12 Asian F. mandshurica. All F. mandshurica remained healthy with little evidence of EAB injury. Despite heavy EAB infestation, F. pennsylvanica radial growth in 2011 to 2022 remained relatively high. Results show F. nigra is highly preferred and vulnerable to EAB, followed by F. pennsylvanica, while F. americana is an intermediate host and F. quadrangulata is resistant.

As a step toward addressing this issue, we conducted novel acute oral, topical, and soil-based toxicity assays on 9 ground beetle species (Coleopetera: Carabidae) in response to the neonicotinoid insecticides clothianidin, thiamethoxam, and imidacloprid. From these assays, we calculated 24 h TD50, TC50, LD50, and LC50 values, measured 24 h feeding activity, and recorded beetle survival for 7 d after exposure. Field-realistic oral, topical, or soil-based exposure to neonicotinoids rarely led to acute (<24 h) beetle mortality. Field-realistic topical and oral exposure of multiple tested species did, however, lead to significant sublethal effects-changes to mobility and feeding behavior-and decreased week-long survival. Under field conditions, carabids exposed to neonicotinoid sprays or contaminated food will be at higher risk of mortality from other factors (eg predation and starvation) which may affect their ability to contribute to biocontrol in agroecosystems.

However, pheromone components seem conserved within the genus Monochamus (Coleoptera: Cerambycidae) with the compound 2-(undecyloxy)ethanol (referred to as monochamol) being identified as the sex-aggregation pheromone or putative pheromone attractant for at least 15 species in this genus. This pheromone parsimony suggests the existence of additional isolating mechanisms. Here we describe the results of laboratory and field assays of additional mechanisms, including laboratory volatile collections and field trapping experiments that assessed the potential presence of additional pheromone components, diel rhythms of pheromone production, and phenological/diel flight activity in the reproductive isolation of sympatric populations of three species of Monochamus in the Great Lakes Forest Region of Ontario, Canada. Chemical analyses of volatile extractions indicate that monochamol is produced by male Monochamus maculosus and Monochamus scutellatus, but no qualitative differences were observed in male extracts of these two species suggesting that there are no additional pheromone components that confer specificity. No quantitative differences were found in the production of monochamol by male M. scutellatus during the photophase and scotophase suggesting there is no diel rhythm in pheromone production. Our results indicate that M. scutellatus flies earlier in the season and day than M. maculosus and Monochamus notatus, which could partially contribute to their reproductive isolation. Overall, no obvious differences in pheromone composition were observed but minor differences in flight times were observed, suggesting other isolating mechanisms may exist.","PeriodicalId":11751,"journal":{"name":"Environmental Entomology","volume":" ","pages":"233-242"},"PeriodicalIF":1.8,"publicationDate":"2025-04-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12005948/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143556191","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Consequently, it can impact mosquitoes' survival and efficiency in transmitting disease. Different mosquito species are known to show preferences for flower nectar from certain plants, yet despite the importance of these plant-mosquito associations, knowledge of such biotic interactions is sparse. Here, we present a systematic map to address the question: \"Which nectar do mosquitoes feed on?.\" The mapping process identified 49 articles (comprising 51 studies) meeting inclusion criteria, detailing 397 records of 74 mosquito species feeding on nectar from 145 plant species and 109 genera. Data extracted from the map were then analyzed to better understand if mosquitoes showed preferences for specific plant nectar. A key finding from this study is clear evidence supporting the hypothesis that mosquitoes exhibit preferences for nectar from particular plant species, including 77 species of plants and 58 genera for Aedes species, 18 species of plants and 17 genera for Anopheles species, and 16 species of plants and 16 genera for Culex species (all 3 genera belong in Diptera: Culicidae). Our study also highlighted the need for further field and laboratory work in time and space and using methods that randomly selects plant species for investigation.

There are an array of abiotic and biotic agents that have been shown to trigger hormesis; most commonly studied are chemicals, temperature, and low oxygen. Investigations into low-oxygen exposures that activate the hormetic response reveal that insect performance can be dramatically improved by single short low-oxygen events, but the focus of this work has been primarily on short-term, transitory protection afforded by hormesis. Few reports examine whether the effect is longer lasting or lifelong. We previously reported that one hour of anoxia was enough to induce a hormetic response in the alfalfa leafcutting bee, Megachile rotundata (Hymenoptera: Megachilidae). Here, we investigated the long-term effects of this response by looking at starvation resistance, flight, and locomotory activity throughout the life of the adult bees. In addition, we studied the effects of anoxia hormesis on multiple reproductive metrics. Anoxia hormesis had lifelong positive effects for flight in both sexes. We also recorded higher starvation survival in bees that experienced hormesis. This improvement in performance came at a steep reproductive cost (ie reduction in fecundity). However, no costs or benefits were passed to the next generation. We hypothesize that using anoxia hormesis in the context of pollination services by this species should result in bees that are more active in the field, thereby increasing the numbers of visits to flowers throughout their entire life.","PeriodicalId":11751,"journal":{"name":"Environmental Entomology","volume":" ","pages":"320-330"},"PeriodicalIF":1.8,"publicationDate":"2025-04-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143623765","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}

The interannual abundance of H. zea is closely linked to climactic variables that influence overwintering survival, as well as within-season host plant availability that drives generational population increases. Although the abiotic and biotic drivers of H. zea populations have been well documented, prior temporal H. zea modeling studies have largely focused on mechanistic/simulation approaches, long term distribution characterization, or degree day-based phenology within the growing season. While these modeling approaches provide insight into H. zea population ecology, growers remain interested in approaches that forecast the interannual magnitude of moth flights which is a key knowledge gap limiting early warning before crops are planted. Our study used trap data from 48 site-by-year combinations distributed across North Carolina between 2008 and 2021 to forecast H. zea abundance in advance of the growing season. To do this, meteorological data from weather stations were combined with crop and soil data to create predictor variables for a random forest H. zea forecasting model. Overall model performance was strong (R2 = 0.92, RMSE = 350) and demonstrates a first step toward development of contemporary model-based forecasting tools that enable proactive approaches in support of integrated pest management plans. Similar methods could be applied at a larger spatial extent by leveraging national gridded climate and crop data paired with trap counts to expand forecasting models throughout the H. zea overwintering range.","PeriodicalId":11751,"journal":{"name":"Environmental Entomology","volume":" ","pages":"378-385"},"PeriodicalIF":1.8,"publicationDate":"2025-04-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12005949/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143074280","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
