Native to China and the Korean peninsula, ALB is invasive in both North America and Europe. Due to the large environmental and economic impacts associated with ALB, much effort has been placed on its management and eradication from invaded areas. Eradication programs consist of visual surveys, regulatory quarantines, host removal, public outreach and education, and in some cases, insecticides. Host removal is effective but is laborious and costly, and while insecticides have been useful as a component of some eradication programs, they can be expensive, ineffective, and environmentally detrimental. Thus, several arthropod biological control agents (BCAs) have been evaluated which could support a more environmentally friendly management strategy to supplement traditional ALB management tactics. Here, we review the biological control strategy for ALB, including the exploration within the native and invaded ranges of the pest, to find potential arthropod BCAs. We discuss the ecological premise behind the method as well as the potential for its success, and we identify knowledge gaps and future considerations for the enactment of this method. While biological control shows promise, care will be needed in utilizing this method, and further research must explore the success of BCAs in field settings.","PeriodicalId":11751,"journal":{"name":"Environmental Entomology","volume":" ","pages":"679-690"},"PeriodicalIF":1.5,"publicationDate":"2025-08-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12364626/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142681289","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}

Population dynamics, growth rates, and life cycle durations were assessed through destructive sampling every 4 d for each temperature treatment. To analyze temperature-dependent growth and development, a nonlinear model was fitted to the intrinsic growth rate values at each temperature, allowing us to determine the species' optimal temperature and corresponding maximum growth rate. In the laboratory, X. bispinatus exhibited optimal growth rates between 26 °C and 29 °C, with rates of 0.10 and 0.12, individuals/individuals/day, and life cycle durations of 20 and 16 d, respectively. However, based on the fitted growth curve, the thermal optimum was estimated at 26.2 °C, where the maximum intrinsic growth rate reached 0.13 individuals/individuals/day. Given its potential to transmit Harringtonia lauricola, these findings provide valuable insights into the thermal effects on X. bispinatus throughout its life cycle and offer a practical approach for estimating growth rates and thresholds in species with cryptic behavior or where cohort tracking is challenging for demographic assessments.","PeriodicalId":11751,"journal":{"name":"Environmental Entomology","volume":" ","pages":"976-988"},"PeriodicalIF":1.5,"publicationDate":"2025-08-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144505163","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}

Here, the effects of Russian olive on soil chemical properties and invertebrate communities in riparian zones of the southwestern United States were investigated. Russian olive stands were compared to native cottonwood stands and restoration sites by analyzing soil nitrogen (N), phosphorus (P), and moisture levels, and arthropod diversity and abundance. Sites where Russian olive is present led to a net increase in soil nitrogen, a decrease in soil phosphorus, and greater soil moisture compared to both native cottonwood stands and restoration sites. Native cottonwood stands showed lower soil N and higher P levels, as well as higher arthropod diversity. This increased diversity could be linked to the soil's nutrient stoichiometry, as there is a negative correlation between taxonomic diversity and the soil N:P ratio. Moreover, there was a greater abundance of detritivorous arthropods in Russian olive stands compared to native vegetation. Soil nitrate (NO3-) levels showed a strong positive correlation with detritivorous arthropod abundance (r2 = 0.98), but only a moderate correlation with herbivores (r2 = 0.38), and NO3- was unrelated to predator abundance (r2 = 0.01). These results suggest that Russian olive stands can alter soil chemistry in ways that disproportionately benefit detritivores, potentially disrupting the balance of arthropod communities and reducing overall biodiversity in riparian ecosystems. The study underscores the need for careful management of invasive, symbiotic N2-fixing plant species to preserve the ecological integrity of riparian habitats.","PeriodicalId":11751,"journal":{"name":"Environmental Entomology","volume":" ","pages":"773-789"},"PeriodicalIF":1.5,"publicationDate":"2025-08-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144625617","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}

First, we evaluated symbiotic effects on the female reproductive capacity with varying numbers of males available to a female. Overall, symbiotic females displayed on average a 1.8-fold increase in egg production compared to aposymbiotic individuals. However, eggs from symbiotic females were on average 42% less viable, compared to those from the aposymbiotic, when paired with single male. The decrease in the hatchability was alleviated to 12% when paired with 3 males. Consequently, this yielded significant increase in the number of viable offspring by symbiotic females when multiple males were available. Second, we evaluated symbiotic effects on male morphometric characteristics including hind legs used as weapon, and found significant increases in hind leg sizes associated with symbiosis. Finally, we investigated mating behaviors between a female and 2 males of different symbiotic status. Symbiotic females displayed on average a 1.4-fold increase in the number of copulations compared to the aposymbiotic. From both female types, however, no significant difference was observed in their mate choice and copulation success rate between aposymbiotic and symbiotic males. However, symbiotic females exhibited on average 17% reduction in copulation duration compared to the aposymbiotic. Copulation failure was caused more frequently by female's rejection than by intruder male's disruption for both female types. Our study demonstrates that symbiotic females benefit from the symbiosis increasing their reproductive capacity and copulation frequency.","PeriodicalId":11751,"journal":{"name":"Environmental Entomology","volume":" ","pages":"810-818"},"PeriodicalIF":1.5,"publicationDate":"2025-08-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144157570","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}

These clearings can be large and influence plant communities affecting rangeland management. In some cases, colony density may be increased by grazing but studies are sparse with conflicting results. We examined the effects of grazing on 2 harvester ant species (Pogonomyrmex occidentalis and Pogonomyrmex rugosus) at 5 sites in northern Arizona. We used preestablished grazing-exclusion treatments to compare colony density and spacing adjacent to and within grazed areas. At all sites, colony density was marginally higher in excluded treatments. Only P. occidentalis showed significant spatial patterns in response to grazing, where nests were evenly spaced on small distances (>5 m) in the grazing-excluded treatment. We observed large differences in nest size and density between ant species. Pogonomyrmex occidentalis made larger nests and cleared more land area than P. rugosus. Pogonomyrmex occidentalis peaked in density at 37 nests/ha occupying 1.87% of land area with smaller nearest neighbor distances (10.6 to 13.6 m), while P. rugosus peaked at 16 nests/ha occupying 0.20% of land area with larger nearest neighbor distances (17.9 to 24.3 m). Together our results provide limited but interesting evidence of negative effects of grazing on harvester ant nests. We discuss our findings in the context of other studies measuring colony densities in rangelands and conclude that grazing effects on nest spatial arrangements are inconsistent and differ among locations, highlighting the need for future studies.","PeriodicalId":11751,"journal":{"name":"Environmental Entomology","volume":" ","pages":"764-772"},"PeriodicalIF":1.5,"publicationDate":"2025-08-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144505158","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}

Fruiting patterns differed among plants. Oregon grape and bitter cherry fruited once in relatively narrow temporal windows, while red osier dogwood and snowberry fruited multiple times or more widely through the season. Fruiting times differed for plants from earlier to later: based on fruit set, Oregon grape < red osier dogwood = bitter cherry < snowberry; first ripening fruit, Oregon grape < bitter cherry = snowberry; percent mature fruit in early August, Oregon grape = red osier dogwood < bitter cherry < snowberry. Mean fly eclosion times generally matched host fruiting times: red osier dogwood fly < Oregon grape fly = bitter cherry fly < snowberry fly. Parasitoid and fly eclosion matched except snowberry fly wasps eclosed before bitter cherry fly wasps. Differences in eclosion times between flies or wasps resulted in allochronic isolation from 1% to 96%. Nonconcordance between timing of fruit maturity and fly/wasp eclosion may be related to differences in precise host fruit or fly stages attacked by different species.

Beginning in 1998, studies of fungal entomopathogens for ALB control were begun, followed by studies with entomopathogenic nematodes, Bacillus thuringiensis Berliner, and microsporidia. Studies with entomopathogenic fungi initially focused on a commercialized method used for application of Beauveria asiatica against adult cerambycids in Japanese orchards: cerambycids walk across bands covered with infective spores of entomopathogenic fungi that are attached around trees. For use in the United States, Metarhizium brunneum Petch F52 was grown in fungal bands and tested against adult ALB in US quarantine labs as well as in the field in China. Fungal infection reduced female longevity, fitness, and flight. Long-lived M. brunneum microsclerotia formulated in hydromulch were investigated as an alternative application method. Several species of entomopathogenic nematodes applied to ALB emergence holes showed promise for infecting and killing ALB larvae.
