This surge in solid waste accumulation is putting immense pressure on landfill capacities, underscoring the urgent need for innovative waste management strategies, especially in regions still heavily dependent on traditional systems. This study investigates the potential of black soldier fly larvae to process 3 distinct types of landfill waste: food waste, aged landfill waste, and municipal solid waste sludge. Neonate larvae (0-1-day-old) were applied to 2.5 ± 0.02 kg of waste to assess key performance metrics, including waste reduction (% dry matter), survival rate (%), bioconversion rate (% dry matter), and waste conversion efficiency (% dry matter). The results revealed that black soldier fly larvae effectively reduced waste by 41.6-55.8%. However, across all treatment groups, the larvae exhibited low efficiency in converting waste into biomass. Notably, while performance comparisons with the control feed (commercial chicken feed) yielded predominantly adverse outcomes, the fresh waste treatment showed a marginally positive impact on waste reduction. These findings highlight the potential of black soldier fly larvae in landfill waste management while also identifying significant limitations in bioconversion efficiency. To optimize the application of black soldier fly larvae in sustainable waste management practices, further research is warranted to explore innovative pretreatment methods and other factors that could enhance their efficacy in biomass production.","PeriodicalId":11751,"journal":{"name":"Environmental Entomology","volume":" ","pages":""},"PeriodicalIF":1.5,"publicationDate":"2025-09-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144991762","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, all bark beetles vector fungi that may provide nutrition to them, improve substrate conditions, or act as antagonists, hindering their success. This study introduces a paired-tube choice test arena to assess bark beetle-fungal interactions using minimal phloem-media. We hypothesized that primary bark beetles with mycangial fungi (eg Dendroctonus frontalis Zimmermann and Dendroctonus barberi Hopkins) avoid phloem infested with nonmycangial fungi such as Ophiostoma minus (Hedgcock) Sydow & P. Sydow, while secondary beetles like Ips pini Say, which do not rely on mycangial fungi, show no preference for fungal-infested or fungus-free phloem. Our findings revealed that D. barberi preferred uninfested phloem, whereas I. pini preferred the O. minus-infested phloem. Interestingly, D. frontalis did not show a preference for either uninfested phloem or O. minus-infested phloem. These results underscore the importance of understanding the effects of fungal symbionts on tunneling behavior, with potential applications in pest management, such as deploying cues from antagonistic fungi as repellents.","PeriodicalId":11751,"journal":{"name":"Environmental Entomology","volume":" ","pages":"819-827"},"PeriodicalIF":1.5,"publicationDate":"2025-08-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144505156","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}

Understanding the dominant natural enemies of pests in the crop is crucial for optimizing conservation strategies to enhance ecological services. Through field surveys, this study revealed that ladybugs and lacewings had the highest dominance and temporal niche breadth indices among predatory insects. The temporal niche overlap index between ladybugs (predominantly Hippodamia variegata (Goeze)), and C. juglandicola was the highest, with their population peaks strongly coinciding. In cage experiments with H. variegata under varying predator/aphid ratios (1 : 50, 1 : 100, 1 : 150, 1 : 200, 0), we found that a predator-to-prey ratio exceeding 1:100 effectively suppressed C. juglandicola population growth, achieving over 70% biocontrol efficacy within 1 wk. Furthermore, in the field, the growth rate of C. juglandicola was significantly and negatively correlated with the ratio of ladybugs to aphids. Path analysis indicated that for every unit increase in the predator-to-aphid ratio, biocontrol efficacy improved by 63.4% (the standardized effect coefficient in path analysis), and the aphid population growth rate decreased by 65.2%. This study confirmed that H. variegata is the dominant predator of C. juglandicola in walnut orchards of southern Xinjiang. A predator/aphid ratio exceeding 1:100 effectively suppressed aphid population growth, maintaining it at low levels. These findings provided critical theoretical support for developing biological control strategies using H. variegata to manage C. juglandicola in walnut orchards of southern Xinjiang.","PeriodicalId":11751,"journal":{"name":"Environmental Entomology","volume":" ","pages":"747-755"},"PeriodicalIF":1.5,"publicationDate":"2025-08-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144505159","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}

Attempts to resolve this paradox using population genetics strategies have been hindered by the lack of gene flow-genetic drift equilibrium in much of North America related to this species' recent range expansion out of the Great Plains across the Corn Belt. We addressed this challenge by studying a longer-established population in northeastern Colorado and western Kansas, where D. v. virgifera has been resident for >175 yr. We assessed population differentiation using 2,036 single-nucleotide polymorphism markers to obtain indirect estimates of dispersal distances. Significant isolation by distance and pairwise FST estimates across 14 locations suggest these populations are at or near gene flow-genetic drift equilibrium. Low FST values and shallow isolation-by-distance slopes suggest gene flow over longer distances (280 km) than supported by many direct measures of dispersal distance, another type of dilemma known as Slatkin's Paradox. Indeed, based on estimates of adult population density and Wright's neighborhood at each location, median estimated lifetime dispersal of ~87% of adults was only 174 m. Together, our genetic evidence and findings from earlier studies suggest that D. v. virgifera populations consist of 2 behavioral phenotypes, migrants that engage in long-distance dispersal and residents that disperse only locally by diffusion. The resulting bimodal dispersal distribution resolves both Reid's and Slatkin's paradoxes.","PeriodicalId":11751,"journal":{"name":"Environmental Entomology","volume":" ","pages":"989-1005"},"PeriodicalIF":1.5,"publicationDate":"2025-08-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144186813","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 aims of this study were to determine how the introduction of S. oryzae, A. flavus, or both in a grain mass affected (i) the fitness of S. oryzae, and (ii) the abiotic conditions in a grain mass. Containers with 300 g of wheat were established with no insects or added microbes, 75 mixed-sex S. oryzae adults only, 11.6 g of A. flavus-inoculated grain only, or both, and dataloggers were placed in the masses to record temperature and relative humidity every 5 min. After 60 d, progeny were counted, and grain moisture was also measured. Although mean temperature was not consistently altered in the presence of A. flavus or S. oryzae, the combined inoculation of A. flavus and S. oryzae in a grain mass consistently elevated relative humidity by 7% to 8%. The presence of A. flavus or S. oryzae consistently elevated grain moisture from 10.8% prior to the experiment to about 13%. Importantly, there were 203-fold more F1 progeny produced by S. oryzae when A. flavus was present compared to when it was absent in a grain mass, possibly indicating a mutualistic relationship.

We used field-collected egg masses from Pennsylvania, USA, and treated them with short (1 or 12 h) and long (10 or 15 d) low temperature exposures (0 °C to -25 °C). We determined that eggs were chill susceptible, and their supercooling points ranged from -17.4 °C to -27.7°C. We observed successful hatch after short- and long-term exposure to temperatures below -20 °C. Hatch rates were lower at or below -20 °C in the short exposures, or -15 °C in our long exposures experiments than hatch rate in egg masses not exposed to any treatment. Because L. delicatula eggs survived temperatures near their supercooling points, -27.7 °C could be used as an estimate of the lower lethal temperature. Our findings suggest that L. delicatula may be able to survive in colder climates than initially thought. Of the locations where L. delicatula has been intercepted in Canada-central and eastern provinces-Winnipeg is the only location where frequent or intense cold spells are likely to prevent hatch. Thus, low winter temperatures may not limit L. delicatula overwinter survival in many regions of Canada or other parts of the world that experience similar winter conditions.","PeriodicalId":11751,"journal":{"name":"Environmental Entomology","volume":" ","pages":"890-898"},"PeriodicalIF":1.5,"publicationDate":"2025-08-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144526959","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 assessed the exposure and impact of Clarifly (active ingredient [a.i.] diflubenzuron), LongRange (a.i. eprinomectin), and Safe-guard (a.i. fenbendazole) on beetles and flies. Using high-performance liquid chromatography, we quantified the residual concentrations of these chemicals in cattle feces for 150 d. We found fenbendazole excreted within the first 3 d after treatment, while diflubenzuron and eprinomectin persisted for 8 to 12 wk. To estimate the concentrations of these active ingredients that are toxic to beetles, we dosed cattle dung with diflubenzuron, eprinomectin, or fenbendazole, allowed insects to colonize in the field, and monitored the emergence of beetles. Dung beetle (Scarabaeidae) abundance was negatively impacted by diflubenzuron and eprinomectin while fenbendazole had no negative effects. Predatory beetles, families Carabidae, Histeridae, Hydrophilidae, and Staphylinidae, were unaffected by all chemicals. We found that dung from animals treated with LongRange was toxic to Scarabaeidae for 30 to 90 d after treatment. Similarly, diflubenzuron was toxic to Scarabaeidae when cattle consistently consumed it, although concentration of diflubenzuron in dung varied when cattle were fed using Clarifly. In contrast, the active ingredient in Safe-guard, fenbendazole, was not toxic at 10 mg/kg. Although, we found this product excreted at higher concentrations for 1 d after treatment, it likely poses little risk.
