Adult weevils are managed with insecticides. Reduced risk management could include the development of traps for monitoring. Adult weevils form mating aggregations on soybean and produce low-volume sounds. The objective was to characterize the sounds produced by groups of males and females, and to determine whether the weevil group size influences the acoustic signals. Adult weevils were field collected and then sorted into groups of males and females in the laboratory. Groups of adult males or females (3, 5, or 10) were used for acoustic recordings. Adobe Audition software was used to visualize and measure the duration and peak fundamental frequency of the sounds. Two acoustic signal patterns were produced by both males and females: paired chirps and a series of chirps. Paired chirps were produced by all group sizes of males and females. The series of chirps was produced by larger groups of males more frequently than smaller groups. For females, the series of chirps was detected more frequently in small groups of 3 females than in larger groups. Paired chirps may play a role in species identification; they have been characterized for other weevil species, and chirp durations vary among the species recorded. The series of chirps produced occur in other weevil species as well and are associated with stress or disturbance. The acoustic patterns produced by R. nigerrimus and their behavioral context could be further explored for potential inclusion in an acoustic trap to detect and monitor this weevil.","PeriodicalId":94077,"journal":{"name":"Journal of economic entomology","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-07-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144639109","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}

Insecticides are used to manage this pest, and application frequency typically depends on H. zea abundance in the field. Pheromone-baited traps are used to estimate H. zea abundance, but differences in trap designs and lure types likely impact moth capture. This study comprehensively evaluated the influence of currently available traps, pheromone lures, and their combinations on H. zea moth captures across the eastern United States in 2022 and 2023. Moth capture was evaluated using combinations of the Hartstack, Heliothis, and green bucket traps with the Hercon (87% (Z)-11-hexadecenal, 8% (n)-hexadecanal, 3% (Z)-9-hexadecenal, and 2% (Z)-7-hexadecenal), Scentry, Trécé, and Alpha Scents (all 3 lures contained 97% (Z)-11-hexadecenal and 3% (Z)-9-hexadecenal) pheromone lures. Additionally, moth capture was evaluated using a modified Hartstack trap, which had the same bottom opening size as the Heliothis trap. Results demonstrated that the Hartstack trap captured significantly more moths than the Heliothis trap, but the modified Hartstack captured similar numbers of moths as the Heliothis trap, suggesting that the Hartstack's larger trap opening may increase moth capture compared with the modified Hartstack. The Hercon lure attracted significantly more moths than the Trécé and Alpha Scents lures, but attracted a similar number of moths as the Scentry lure. These findings are valuable for improving H. zea moth capture and will inform future studies that refine insecticide application frequency guidelines based on moth capture rates.","PeriodicalId":94077,"journal":{"name":"Journal of economic entomology","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-07-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144639114","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 emerald ash borer is established in eastern North America, it was recently detected in Forest Grove, Oregon and in Vancouver, British Columbia, raising concerns that it may spread across the Pacific Northwest riparian ecosystems dominated by ash. A quarantine zone has been established in Oregon, but future mitigation depends on assessing the spread to new regions. Here, we used habitat suitability models and dispersal simulations to predict the potential spread of emerald ash borer. Specifically, we compared climate spaces occupied by Oregon and British Columbia populations with other native and introduced populations, and then used habitat suitability models and dispersal simulations to predict future distributions. We show that the newly established Oregon and British Columbia populations currently occupy relatively narrow climate niche, and many suitable niche spaces are unoccupied in the Pacific Northwest, indicating potential for range expansion. We also show there are vast areas of suitable habitat that extend south of the present quarantine zone throughout inland western Oregon and north into Washington. In Vancouver, the most suitable habitat was found along the Fraser River, where emerald ash borer could disperse inland. Dispersal models suggest that, without intervention, emerald ash borer could disperse into Washington within 2 yr, throughout western Oregon in 15 yr, and reach California in 20 yr. Our work supports intensive quarantine efforts for emerald ash borer and identifies areas where monitoring and management efforts should focus.","PeriodicalId":94077,"journal":{"name":"Journal of economic entomology","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-07-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144639111","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}

Spirotetramat, a systemic insecticide, is currently recommended for early season use in bulb onion production, but its residual effects based on application timing, frequency, and plant age are poorly understood. From 2016 to 2023, we conducted a series of trials assessing the impact of these factors on thrips control. We compared 2 application timings and frequencies on onion thrips management in bulb onions. Finally, we conducted a separate green onion experiment, altering plant age and application frequency to determine the effect on onion thrips populations and spirotetramat uptake by the plant. Our results showed that 2 sequential applications of spirotetramat reduced onion thrips densities by 50%, but application timing had no impact on thrips densities in both bulb and green onions. Green onions that received 2 applications of spirotetramat had significantly higher spirotetramat levels in the leaf tissue than those treated once. In green onions, more spirotetramat was detected in young plants compared with older ones, and there was a negative correlation between spirotetramat levels in leaf tissue and onion thrips densities on plants. Overall, our results indicated that 2 applications of spirotetramat are necessary for effective onion thrips control on bulb onion and green onion, likely due to increased insecticide levels in plant tissue.","PeriodicalId":94077,"journal":{"name":"Journal of economic entomology","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-07-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144639113","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}

Integrated pest management strategies are being explored, but current options remain limited and often insufficient. In invaded regions, local natural enemies are mostly generalist pupal parasitoids, which have proven inadequate for controlling this rapidly spreading pest. Conversely, in its native range, D. suzukii is host to more specialized larval parasitoids that may mitigate its impact on fruit crops. Extensive foreign exploration and risk assessments identified the larval endoparasitoid Ganaspis kimorum (Hymenoptera: Figitidae) as the most suitable candidate for classical biological control. In 2021, Italy launched a propagative biocontrol program utilizing a Japanese population of G. kimorum. Here, we present the results from the first 4 yr of releases conducted in Northeast Italy, where the parasitoid was released at 20 different locations. We provide an overview of the monitoring activities at these sites to determine whether G. kimorum has successfully established and to assess its parasitism levels on both the target pest and nontarget species. Results confirmed that G. kimorum is a specialist on D. suzukii and likely does not compete with local parasitoids for reproductive resources. Collected data also suggest that the parasitoid has become established in several locations, and it is gradually expanding its range from the initial release sites. Four years after the initial release of G. kimorum, the data gathered offers valuable insights into the efficacy and ecological implications of this biocontrol strategy.","PeriodicalId":94077,"journal":{"name":"Journal of economic entomology","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-07-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144639112","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}

Conservation practitioners are managing Hemlock woolly adelgid through a statewide, landscape-level pesticide management plan. The traditional method of using randomized branch sampling to estimate infestation levels is time-consuming but allows managers to monitor how Hemlock woolly adelgid responds to treatments. Our main objective was to determine if alternative sampling techniques produce data that is equivalent to field methods, such as randomized branch sampling, for estimating infestation levels. We selected 6 treated sites and 3 untreated sites in west Michigan. During the fall and winter of 2022, we estimated the densities of the sistens generation using a randomized branch sampling method, and during the summer of 2023, we deployed 5 traps at each site to capture adelgid crawlers and performed qPCR analysis to quantify Hemlock woolly adelgid DNA. To determine if trap data could be used as a method to assess Hemlock woolly adelgid infestation levels, we evaluated the relationships between (i) crawler counts and qPCR values (gene copies/reaction), (ii) sistens counts and qPCR values, and (iii) sistens counts and crawler counts. We found that trap data (ie qPCR values and adelgid crawler counts) had comparable correlations with traditional methods, particularly during the peak crawler period. However, the strength of these relationships is influenced by factors such as infestation level and temporal variation.","PeriodicalId":94077,"journal":{"name":"Journal of economic entomology","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-07-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144628343","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}

Legumes (family Fabaceae), unlike grapevines (Vitis vinifera L.), are preferred feeding and reproductive hosts for S. festinus. Here, we analyzed the development and behavior of S. festinus on snap beans (Phaseolus vulgaris) in comparison to alfalfa (Medicago sativa) and grapevines, with an emphasis on colony establishment and population growth. Snap beans supported all stages of S. festinus development, promoting feeding, reproduction, and colony establishment, as well as supporting a faster life cycle, particularly on detached trifoliates in controlled environmental chambers, compared with alfalfa. Moreso, social aggregation of S. festinus adults was observed on snap bean plants with the petiole as a preferred feeding site. A preference toward grapevine petioles was also seen, though their survival and aggregation behaviors drastically declined on this nonlegume host. Dissecting the alimentary canal of S. festinus revealed more orange, refractive oil droplets, and air bubbles in specimens from grapevine compared to specimens from snap bean or alfalfa, suggesting possible disruptions in digestive processing or nutritional deficiencies with the former host. Together, our findings highlight snap bean as an ideal host for rearing populations of S. festinus to be used in grapevine red blotch virus transmission studies.","PeriodicalId":94077,"journal":{"name":"Journal of economic entomology","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-07-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144610735","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}

However, they also cause extensive damage in live trees and pose serious risks to tree health as a result. The urban tree canopy in areas with established populations of Coptotermes are therefore at risk of loss of trees over time, and many urban forests within municipality parks in their introduced range may experience tangible canopy alteration. This can have wide-reaching negative impacts on the ecology of these parks and to the public that utilize them. This 5-yr long study utilized eight parks (1,304 trees) to demonstrate how a simple visual monitoring/bait approach can identify and eliminate termite colonies infesting trees and maintain minimal termite activity within public green spaces. Here, we demonstrate that the systematic direct application of an experimental above-ground chitin synthesis inhibitor (CSI) bait formulation to trees can eliminate termite activity and protect trees. However, owing to high termite pressure, colony reinfestation is likely over time, and municipalities may have to establish perennial programs that would include regular monitoring and treatment as needed. Such a long-term strategy would minimize tree loss, while using a termite-specific formulated pesticide with a low amount of active ingredient. This pilot study demonstrates that it can be achieved, but ultimately, the success of this approach relies on technically competent staff that can readily identify the signs of active Coptotermes infestation in trees and access to above ground CSI bait formulations.","PeriodicalId":94077,"journal":{"name":"Journal of economic entomology","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-07-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144610724","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}
