(Hymenoptera: Apidae) winter colony mortality has reached sustained high levels and beekeepers depend on the availability of mated honey bee queens in early spring to recoup colony losses. Unfortunately, importing mated queens from other countries is currently the only reliable option meeting the demands of commercial beekeeping each spring in Canada. However, relying on queen imports brings another set of challenges, as supply chains can be disrupted, border crossings closed, imports prohibited, and the transportation of live animals can be stressful. This study explored the potential for Canadian beekeepers to supply queens in early spring by overwintering queens in queen banks that mated the previous summer. Queens were overwintered indoors in five queen banks. The following spring, the overwintered banked queens and a group of newly mated imported queens were introduced to colonies to evaluate queen introduction success and colony performance and survival over the following year. Queen survival in overwintered queen banks was low, with only 15% queen survival overall. Sperm viability of the banked queens prior to overwintering in queen banks was 30% higher than queens post-overwintering in queen banks. However, queen introduction success in the spring 2021, colony size, honey yield, and winter survival did not differ among queens that overwintered in queen banks and newly mated queens that were imported that spring. These results suggest banked overwintered queens have comparable performance to newly mated imported queens; although, overwintering mated queens in queen banks is risky, as entire queen banks can be lost, significantly reducing queen survival and the availability of mated queens in early spring.","PeriodicalId":94077,"journal":{"name":"Journal of economic entomology","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-06-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144512950","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

High temperature significantly decreased the water content, but increased malondialdehyde content in female and male adults with the increase in temperature.

In this study, we first evaluated the feasibility of using the currently approved methyl bromide (MB) treatment for imported nursery plants (IMP) against the longtailed mealybug, Pseudococcus longispinus. We then assessed ethyl formate (EF) fumigation as a potential MB-alternative treatment and tested 2 nematicides against the root-lesion nematode, Pratylenchus penetrans C. Additionally, we examined the impacts of these treatments on the quality of the IMP. During commercial trials at an importing port in Republic of Korea, the approved MB treatment of 40 g/m³ for 2 h for IMP did not result in complete control of P. longispinus. Moreover, the MB treatment caused severe and irreversible damage to the treated plants. In contrast, the suggested dose of EF (35 g/m3 for 4 h) caused significantly less phytotoxicity on the treated plants than did MB, and 66% of tested species that suffered moderate to severe treatment damage recovered within the 30 d post-fumigation period. The efficacy of EF was also confirmed in a commercial-scale trial, suggesting that EF is a feasible alternative to MB, showing similar efficacy on P. longispinus but much lower phytotoxicity. For P. penetrans, dipping plant roots in Allstar or Nemakick at 0.5 ml/L for 1 h or 4 ml/L for 10 min resulted in complete control of P. penetrans with no apparent phytotoxicity on the treated IMP.

When damaged by insect herbivores, plants emit herbivore-induced plant volatiles (HIPVs) that can affect pest performance, recruit biocontrol agents, and trigger defence responses in neighboring plants. While plant communication via HIPVs has been well-documented over the past few decades, key aspects, such as the specific biochemical mechanisms underlying defence activation in neighboring plants and the variation in response to herbivory, remain poorly understood. This study aims to investigate the effect of HIPVs released by aphid (Brevicoryne brassicae)-infested Brassica napus (emitter) plants on neighboring uninfested conspecific plants (receiver). After 48 h exposure, emitter plants were discarded, and receiver plants were utilized in bioassays to assess aphid performance (fecundity and survival), preference, as well as amino acid and glucosinolates contents of receiver host plants. Results revealed that receiver plants showed a significant reduction in aphid fecundity, although no significant effect on aphid survival was observed. Aphid feeding preference was significantly altered, with B. brassicae showing a reduced preference for receiver plants. Additionally, significant increases in some key amino acids and total concentrations were recorded in receiver plants. Glucosinolates (GSs) analysis showed a significant change in total GS content, with a significant increase in the individual GSs, glucoiberin (GIB), and glucoraphanin (GRA). Current findings provide evidence that receiver plants activate their defence mechanism against B. brassicae by altering amino acid and glucosinolate levels. This study highlights the potential of HIPVs to enhance sustainable pest management strategies.","PeriodicalId":94077,"journal":{"name":"Journal of economic entomology","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-06-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144512952","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this study, the development and reproduction of N. californicus reared on natural prey Tetranychus urticae Koch (Acari: Tetranychidae) and alternative prey Oulenziella bakeri Hughes (Acari: Winterschmidtiidae) were compared using age-stage, two-sex life tables.

Life table results showed that the natural prey strain developed faster, lived longer, and had a higher fecundity than the alternative prey strain. The population parameters (except for the mean generation time) of the natural prey strain were higher than the alternative prey strain. The mate choice study revealed that females of most mating combinations preferred to mate with the males of their own strain. Moreover, with an increase the number of male mites, the mating latency of the two strains gradually increased, while the mating duration shortened.

One of the factors making E. giganteana difficult to manage is the lack of knowledge about when pest management tactics should be applied for maximum effect. To aid with proper timing, our objectives were to determine a lower activity threshold, then use it to develop a growing degree day model to estimate important phenological events in the life history of adult E. giganteana in the field. In addition, we found a good fit between the actual phenological events for E. giganteana from 2020, 2023, and 2024 and the predicted phenological events from trapping data collected in 2019 in Salina, Kansas. The lower activity threshold was determined to be 17 °C using a series of environmental chamber experiments with overwintering E. giganteana larvae. Furthermore, we found a significant correlation between predicted growing degree days for phenological events in 2019 and the actual degree day measurements for those events in subsequent years. Finally, the model was able to accurately predict adult E. giganteana emergence in the field during 2024. We anticipate the model will continue to provide accurate predictions for the coming years, which would allow for improved timing of pest management practices for E. giganteana to be implemented.","PeriodicalId":94077,"journal":{"name":"Journal of economic entomology","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-06-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144512894","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

(Cucurbitales: Cucurbitaceae), is a major vegetable crop in tropical and subtropical regions. Honeybees are considered the primary pollinators of bitter gourd, but they often favor male flowers, which offer nectar and pollen rewards, over female flowers, which do not. This preference can lead to pollination deficiency in bitter gourd. Therefore, exploring alternative pollinators for bitter gourd is crucial to ensure efficient pollination and optimal fruit production, especially in greenhouse settings where honeybee pollination may be less effective. We investigated the pollination efficiency of diurnal hawkmoths and compared it with that of honeybees, bumblebees, and small bees. Our findings revealed that hawkmoths exhibit equal visitation rates to both male and female bitter gourd flowers and deposit a significantly greater number of pollen grains per visit than those bees. This high pollination efficiency, combined with their nonselective flower visitation behavior, makes hawkmoths a promising alternative pollinator for bitter gourd. Our results suggest that hawkmoths could be effective pollinator agents for bitter gourd, especially in greenhouse settings. This discovery opens up new possibilities for sustainable agriculture and could lead to improved pollination strategies for bitter gourd and other cucurbit crops.","PeriodicalId":94077,"journal":{"name":"Journal of economic entomology","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-06-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144512896","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

While there has been some work assessing the microbial ecology of S. zeamais, none has directly assessed whether they transfer microbes to new food patches. Thus, we evaluated the ability of both species to vector microbes when given the opportunity to forage on sterilized potato dextrose agar dishes after a 0, 24, or 72 h dispersal period in a sterilized container. We subsequently photographed the dishes at 3 and 5 d after introduction and quantified the microbial growth using ImageJ. In addition, we isolated unique morphotypes of fungi, extracted DNA and amplified the internal transcribed spacer 5/4 intergenic spacer region, then sequenced to determine fungal identity. We found that 3 species readily vectored several plant pathogenic microbes, including 21 taxa from more than 11 genera, notably Aspergillus spp. Increasing dispersal period (0, 24, 72 h) resulted in a third less microbial growth (mean microbial growth or mean greyscale value from 0 to 255) by S. zeamais after 72 h, while for P. truncatus it resulted in a 2.7-fold increase in microbial growth. Dispersal by S. zeamais (0, 24, 72 h) resulted in 6.6-fold more microbial growth than dispersal by P. truncatus. There was 1.5- to 3.7-fold more microbial growth after 5 d than 3 d by each species.

Here, we re-tool previously developed AK practices for H. halys management using long-lasting insecticide netting (LLIN) as a low-input, effective killing agent. Simple LLIN AK stations were evaluated for efficacy compared with grower standard practices when hung directly on orchard perimeter fruit trees, hung on posts near, but not touching perimeter trees, and placed outside the orchard perimeter in commercial Mid-Atlantic apple orchards from 2017 to 2019. Treatments in which LLIN stations were attached to or hung near perimeter trees were equivalent to grower standards in terms of H. halys injury. In commercial pear orchards in Washington State in 2018 to 2020, efficacies of several LLIN station designs were evaluated as supplements to grower standard practices. A novel LLIN station design, referred to as the poncho trap, consistently caught nearly 3-fold more H. halys compared to a simple post-deployed \"ghost trap\" design when installed outside orchard perimeters. However, only LLIN stations mounted directly to perimeter trees provided statistically significant reductions in fruit damage. Our overall findings underscore the importance of positioning the pheromone lure, host plant (fruit tree), and LLIN in close proximity for successful AK H. halys management. Results also indicate that poncho trap LLIN fabric flaps could be integrated into near-mounted LLIN stations to further increase efficacy.","PeriodicalId":94077,"journal":{"name":"Journal of economic entomology","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-06-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144512932","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
