Each chiral semiochemical usually consists of 2 enantiomer structures that are non-superimposable mirror images. These contain at least one asymmetric carbon yielding absolute R- or S-stereo configurations that rotate plane-polarized light in a polarimeter in opposite directions to specific amounts. Most chiral insect semiochemicals consist of only one bioactive enantiomer functioning in communication with conspecifics (pheromones) or in interspecific interactions (allomones). Once the absolute configuration of each enantiomer is established, usually by chemical syntheses, and associated with the (±) optical rotations via polarimetry, then chiral gas chromatography-mass spectrometry (GC-MS) and polarimeters are used to identify the bioactive component in behavioral research. We present equations that use the optical rotations of compounds in a polarimeter to characterize the optical purity, specific rotation, enantiomeric excess, and percentage of each enantiomer in solution. We extend the polarimetry equations iteratively to solve for the specific rotation of a compound of interest in solutions of multiple chiral impurities with known proportions and specific rotations (from literature and analyzed by chiral GC-MS and polarimetry). The software allows for improved accuracy in measuring specific rotations of chiral semiochemicals in mixtures, as exemplified in previous literature and test samples. The equations implemented in Java software or webpages for personal computers and smartphones will aid research on the identification of volatile chiral molecules functioning in insect-insect and insect-plant interactions as well as in pest management.","PeriodicalId":11751,"journal":{"name":"Environmental Entomology","volume":"55 3","pages":""},"PeriodicalIF":1.8,"publicationDate":"2026-05-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147835191","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}

We evaluated whether the already widespread use of grain aeration is feasible in the Middle East in silico given the arid and hot weather conditions prevalent in the region. Historical weather data from 2004 to 2023 was obtained for 77 sites in 13 countries in the Middle East, and Sitophilus oryzae populations were predicted for a subset of 10 locations spanning the range of climates in the region. We investigated the potential efficacy of aeration triggered at 15, 18, or 21 °C (compared to unaerated) in silico starting in one of five months from July to November. There was little accumulation of hours below 15 °C, a key developmental threshold, in most of the countries prior to November. Modelled S. oryzae populations were highest in hot desert and warm Mediterranean climates. Aeration was predicted to not suppress populations in the hot desert climate, especially in Egypt, but aeration is predicted to suppress population increase in the relatively milder Mediterranean climates. The strength and direction of the correlation (eg strongly positive) between predicted S. oryzae abundance and grain temperature or hours below threshold indicates effective aeration. Thus, when grain is aerated in locations with climate close to the upper developmental threshold of S. oryzae, it will not be effective. Our study illustrates grain aeration is predicted to be effective in some locations of the Middle East, with climatic features of the biome determining efficacy.","PeriodicalId":11751,"journal":{"name":"Environmental Entomology","volume":"55 3","pages":""},"PeriodicalIF":1.8,"publicationDate":"2026-05-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148250115","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}

Although Ap. certus has displayed the capacity to suppress aphid infestations below pesticide spray thresholds, control levels are variable. Previous research has found hyperparasitoids attacking Ap. certus in the field, but the impact of hyperparasitism on the control of aphid populations remains unclear. This laboratory study investigates some key life history attributes of Alloxysta brevis (Thomson), an aphid hyperparasitoid in North America, and its impact on Ap. certus and soybean aphid populations. First, we dissected Al. brevis adults to show that females emerge with an average of 10 mature eggs, continue to produce eggs after adult eclosion, and can hold over 20 mature eggs at a time. We then investigated hyperparasitism across different Ap. certus larval instars and demonstrated that the highest proportion of Al. brevis adults emerges from first-instar larvae. These results provided context for a mesocosm cage study evaluating the population dynamics between soybean aphid, Ap. certus, and Al. brevis. Hyperparasitism by Al. brevis significantly reduced Ap. certus abundance but did not eliminate its ability to suppress aphid populations in a caged setting, indicating that even under high hyperparasitism pressure Ap. certus can still provide substantial biological control of soybean aphid. Results of the cage study suggest that hyperparasitism could have a stabilizing effect on the Ap. certus population, highlighting the need for further investigation into the impact of hyperparasitoids on pest suppression by primary parasitoids.","PeriodicalId":11751,"journal":{"name":"Environmental Entomology","volume":"55 3","pages":""},"PeriodicalIF":1.8,"publicationDate":"2026-05-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148276361","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}

We examined tree-arthropod relationships across elevational gradients in northern Arizona, comparing foliar and trunk communities on the 2 dominant tree species, pinyon and juniper. Understanding these dynamics is vital for climate-change adaptation and biodiversity management. Using trunk-refugia traps and sweep-netting, we sampled arthropods on trunks and foliage of both hosts and tested how host tree, elevation, and precipitation structured assemblages. We hypothesized (i) trunk and foliar communities would be compositionally distinct; (ii) communities would differ between pinyon and juniper because of host-specific taxa rather than dominance by a single tree species; and (iii) peaks in foliar diversity would occur where cooler, wetter conditions coincided (mid-elevation sites). The study confirmed distinct foliar and trunk communities and strong, taxon-specific host-tree effects. Juniper foliage supported higher foliar richness and diversity in both years, whereas pinyon trunks supported higher arthropod abundance and several trunk-associated taxa. Pinyons and junipers therefore supported unique trunk and foliar assemblages, contradicting previous studies on ground arthropods. We observed host-specific preferences, with spiders, leafhoppers, and parasitoid wasps more common on juniper foliage, while mites were more abundant in pinyon foliage. Climate associations were year- and taxon-specific: precipitation and elevation structured foliar richness in 2019 but were weaker in 2020. Our findings show that host-tree identity was the more consistent predictor in this dataset, whereas elevation and precipitation proxies captured site-level associations with long-term climatic context rather than year-specific weather, providing a spatial baseline for future monitoring under vegetation and climate change.","PeriodicalId":11751,"journal":{"name":"Environmental Entomology","volume":"55 3","pages":""},"PeriodicalIF":1.8,"publicationDate":"2026-05-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13223744/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148137303","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}

Recent increases in S. fulvus damage and resistance to pyrethroids show a need for additional tools to complement insecticides. Cultural practices to advance sunflower bloom before S. fulvus emergence is complete were shown to be effective in the 1980s, but are not in use today. To address growers' concerns, insecticide-free field trials were conducted to assess the efficacy, profitability, and sustainability of S. fulvus avoidance with early planting and early maturing hybrids. In central and western South Dakota, May plantings reduced S. fulvus damage by 60% or more relative to typical plantings from 15 to 20 June, and an early maturing hybrid may further reduce seed damage. However, in North Dakota, early planting did not provide a clear advantage, likely because of relatively low S. fulvus populations. Yields generally showed no negative effect from planting early, but yields were lower for the most common planting period (15-20 June) in central South Dakota. Adult S. fulvus emerged earlier where early planted sunflowers were grown in the previous year, but the benefits of weevil avoidance were not eliminated. The strategy of S. fulvus avoidance through early planting (before ≈ 15 May) and early maturing hybrids seems justified in South Dakota where pest populations are very high and insecticide efficacy is low because of resistance to pyrethroid active ingredients. For other key sunflower-growing areas including North Dakota, avoidance may become useful in the future if S. fulvus populations increase.","PeriodicalId":11751,"journal":{"name":"Environmental Entomology","volume":"55 3","pages":""},"PeriodicalIF":1.8,"publicationDate":"2026-05-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13166878/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147927382","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}

We conducted a 2-yr survey (2024 to 2025) in 316 soybean fields in Missouri to quantify parasitism of adult stink bugs by tachinid flies (Diptera: Tachinidae). In addition, stink bug egg masses were sampled for the presence of egg parasitoids once in 152 soybean fields across the state, and weekly at three locations during the 2025 growing season. Overall, 7.4% of adult stink bugs were parasitized, with higher parasitism observed in males than in females; adult parasitism also varied significantly between years, with 10.4% in 2024 and 6.5% in 2025. Egg parasitism was detected in 9.4% of egg masses and 4.1% of individual eggs collected statewide. Season-long monitoring showed significant differences among locations. Parasitism differed among stink bug species, with eggs of the Brown complex (Euschistus spp.) exhibiting significantly higher parasitism rates than those of Chinavia hilaris (Say) (Hemiptera: Pentatomidae). The egg parasitoids Trissolcus edessae Fouts (Hymenoptera: Scelionidae) and Telenomus podisi Ashmead (Hymenoptera: Scelionidae) were found parasitizing stink bug eggs.

This is especially important for juvenile stages, which are confined to the body of water where they hatched and are unable to relocate for thermoregulation. In an urban desert like Maricopa County, Arizona, where Culex tarsalis and Culex quinquefasciatus are prominent, the macroclimate is strongly influenced by the urban heat island effect where larval thermal maxima are frequently exceeded. Understanding the local temperatures (microclimates) of sites that mosquitoes choose for egg laying and larval development is important for managing mosquito populations and reducing disease risk. We deployed small temperature loggers at multiple breeding sites throughout the city and compared those temperatures to gridded reanalysis macroclimate data. We found that the recorded aquatic microclimates were consistently cooler than corresponding macroclimates and that higher canopy cover further buffered hot temperatures. This suggests that using interpolated macroclimate data to estimate mosquito population dynamics overestimates the thermal stress local mosquitoes actually experience. By using microclimate measures, we can better predict mosquito survival and development, allowing us to better understand disease risk both now and with future warming.","PeriodicalId":11751,"journal":{"name":"Environmental Entomology","volume":"55 3","pages":""},"PeriodicalIF":1.8,"publicationDate":"2026-05-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148276409","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 temporal dynamics varied slightly between years. In 2023, adult emergence began in early May, with a population increase in late May and a peak density in early June. In 2024, emergence occurred earlier (late April); the population abundance increased in mid-May, reaching maximum abundance by late May. The developmental duration of M. aurolineatus varied markedly, with the larval stage lasting the longest (281.71 d) and the egg stage the shortest (13.49 d). Oviposition peaked between mid-June and early July. Larvae began hatching in mid-June and inhibited the soil until the subsequent April. Pupation occurred in mid-April, marking the onset of adult emergence in late April. The ovarian development process could be divided into 6 grades, from grade I to grade VI. Field sampling revealed that by late May, adults at the oviposition peak grade (grade IV) had already appeared, and subsequently collected adults were all sexually mature. Taken together, the analyses of population dynamics and ovarian development indicate that the optimal time for controlling M. aurolineatus is before late May, when the adult population has reached peak abundance but females have not yet oviposited, thereby providing valuable guidance for its management.","PeriodicalId":11751,"journal":{"name":"Environmental Entomology","volume":"55 3","pages":""},"PeriodicalIF":1.5,"publicationDate":"2026-05-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148239221","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}
