However, widespread pyrethroid resistance increases the probability that cockroaches will survive treatments in the field. Many insecticides are applied concurrently or repetitively on a periodic basis, meaning survivors have the chance to be re-treated, but any lasting physiological effects from initial survival may impact the performance of subsequent treatments. We investigated the effects of sublethal deltamethrin exposure on the susceptibility of susceptible (UCR) and resistant (Ryan) strains of German cockroaches. Ineffective pyrethroid treatment was simulated by treating cockroaches with the LD20 of deltamethrin. Survivors were treated again with the same dose of deltamethrin, a food source containing the LC50 of fipronil, or a food source containing the LC50 of indoxacarb. Both strains of cockroaches experienced greater mortality when treated with deltamethrin 3 d (49.8% to 67.6%), after the sublethal exposure. No impact on fipronil or indoxacarb susceptibility was observed after pre-treatment with deltamethrin. Because surviving a deltamethrin treatment did not induce tolerance to deltamethrin or other insecticides, this suggests no within-generation drawback of current conventional management practices of applying multiple treatments in the same site. Furthermore, sequential exposure to deltamethrin caused greater mortality than expected, indicating that this insecticide may remain useful even if initial efficacy is low. Comprehensive examinations of additional resistant strains treated with formulated products are warranted to understand whether these effects may impact field control.","PeriodicalId":94077,"journal":{"name":"Journal of economic entomology","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-06-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144512936","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}

It can kill stressed trees and transmit ophiostomoid fungi that cause blue staining of wood and reduce the commercial value of timber. Ips grandicollis uses semiochemicals produced by conspecifics to locate mates, while semiochemicals from competitors and nonhosts may reduce the reaction to attractants. To investigate methods to exploit these behaviors in a management strategy, we evaluated the impact of 12 potential semiochemical inhibitors of I. grandicollis attraction using traps baited with aggregation pheromone (ipsenol and cis-verbenol) in the beetle's native (northeast Georgia and central Louisiana, USA) and invasive (southeast Queensland, Australia) ranges over 2 yr. In the first trapping experiment (2022 to 2023), 2 semiochemicals (2-phenylethanol and methyl eugenol) significantly decreased attraction to the lure by 35% to 39% in the native range and 55% to 56% in the invasive range. Camphor reduced trap catches in Louisiana (26%) and Queensland (41%) but not in Georgia. In the second experiment (2023 to 2024), the inhibitory effects of methyl eugenol, 2-phenylethanol, and camphor were tested alone and in binary and ternary combinations. The binary combination of methyl eugenol and 2-phenylethanol reduced attraction by 66% in Georgia. However, such differences were not observed in Louisiana. The ternary combination of these compounds reduced attraction by 76% in the invasive range. Further research on these inhibitors could lead to a sustainable push-pull management strategy for protecting pine trees and log stacks from I. grandicollis attacks.","PeriodicalId":94077,"journal":{"name":"Journal of economic entomology","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-06-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144512953","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 case study, we analyzed colony migrations related to flow, modeling distances traveled, and costs per hive using official data systematically collected in Slovenia between 2014 and 2022. During this period, beekeepers recorded between 3,000 and 4,000 migrations annually. In response to economically important forage availability, between 67,000 and 96,300 hives were relocated each year. The most sought-after forage was acacia (Robinia pseudoacacia, 23%), followed by chestnut (Castanea sativa, 22%) and fir (Abies alba, 20%). Migration dynamics varied between years due to weather conditions, resulting in a broad range of cumulative travel distances per year, from 125,161 to 212,080 km. The estimated costs of hive transport per km included motorway tolls, fuel prices, and estimated fuel consumption. Regarding vehicle choice, using a car to relocate a small number of hives (8 to 10) was the most expensive option. A 28-hive trailer for a family car proved to be a near-optimal option, while the most cost-effective method was migration with a truck carrying 72 hives. Nonetheless, throughout the observed period, the cost of migrating 28 hives over 200 km was less than the retail value of 10 kg of honey.","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":"144499955","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}

Several models predicting the interactions have been proposed, each based on different assumption regarding mixture toxicity. However, the lack of consensus on which model to adopt for insecticidal activity has hindered the accurate prediction of mixture toxicity and the identification of synergistic or antagonistic interactions. In the present study, we compared the dose-responses of 14 synthetic insecticides in 3 modes of action groups assigned by the Insecticide Resistance Action Committee. The structure-activity relationships of dose-response parameters were analyzed, with a particular focus on LD50 and Hill slope values, which play pivotal roles in some models. Four widely adopted models, Bliss, Loewe, Highest Single Agent, and Schindler, were evaluated to predict mixture toxicity using Musca domestica L. (Diptera: Muscidae) as the model insect. The Loewe and Bliss models demonstrated 79.1% and 76.9% predictability, respectively, for 91 binary mixtures. To improve predictive accuracy, a 2-step framework was devised. Combinations were grouped based on the similarity of their modes of action, and then the models were selectively applied to the corresponding group. These findings contribute to a better understanding of the development and assessment of mixture-based insecticidal products.","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":"144512891","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}

This is due in part to the number of cockroach baits on the market with various matrix compositions and active ingredients, aiding in the control of insecticide-resistant cockroach populations through bait rotation. However, it remains unclear how cockroach gel baits perform over time and under different environmental conditions. Therefore, we aged six cockroach gel baits for varying times (24 h, 1 mo, 3 mo, and 6 mo) and at three relative humidities (15%, 40%, and 80%), and tested their performance (consumption and efficacy) against fresh baits. German cockroaches consumed various quantities of bait depending upon both bait product and age, with significant declines in aged bait consumption compared to fresh bait consumption for most products tested. However, all baits aged over 24 h caused greater than 93% mortality in all B. germanica (L.) populations. Low relative humidity (15%) did not significantly affect bait consumption or efficacy compared to standard relative humidity (40%), but high humidity (80%) resulted in excessive mold growth (Mucoraceae) in all trials, preventing testing of aged baits at high humidity. Our findings show that cockroach gel baits remain palatable and effective up to 6 mo after application at 40% and 15% relative humidity in laboratory conditions. This suggests that even though consumption declines in comparison to fresh baits, aged baits may play a role in cockroach control for an extended time after application.","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":"144512897","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}

We confirmed that Delftia sp. W1 and Serratia marcescens R1 facilitate the growth of A. lucorum on cotton. The A. lucorum exhibits retarded growth on cotton by removal of these two strains, and its growth performance is restored upon recolonization with these strains. The capabilities of both strains in protein degradation are evident, with S. marcescens R1 exhibiting the most pronounced degradation ability. This study reveals the crucial role of gut microbiota in A. lucorum's adaptation to cotton. We identified two strains from the gut microbiota which contribute to protein digestion in A. lucorum.

This study assessed the susceptibility of a laboratory-susceptible strain (SS) of A. spiraecola to abamectin, imidacloprid, thiamethoxam, and acetamiprid. The LC50 values of A. spiraecola to abamectin, imidacloprid, thiamethoxam, and acetamiprid were 0.13, 1.44, 1.76, and 1.19 mg L-1, respectively. The resistance levels of 8 A. spiraecola field populations in a major apple-growing region were investigated in 2021 to 2023. The resistance ratios (RR) varied in different years and regions. The resistance level of A. spiraecola in the XP (Xingping) region to abamectin was the highest (RR = 42.08) in 2021. Most field populations displayed low or moderate levels of resistance to 3 neonicotinoids. However, the field population of A. spiraecola in LQ (Liquan) region had a high resistance level to thiamethoxam in 2021 with an LC50 of 109.63 mg L-1 and a resistance ratio of 62.29. The resistance levels of A. spiraecola to 4 pesticides were found to be decreasing in 3 yr. Compared to the SS strain, the field populations of A. spiraecola showed no mutations in nAChR, GABA receptor, or GluCl, suggesting that target site insensitivity may not contribute to the resistance.

Since its arrival in Pennsylvania in 2014, L. delicatula has infested 16 additional states and damaged a variety of ornamental plants, trees, and fruit crops: most notably, cultivated grapevines. While available insecticides are effective at killing L. delicatula in vineyards, they require repeated applications due to constant re-infestation by the insect, leading to increased production costs and potential secondary pest outbreaks. An alternative approach would be to repel L. delicatula from vineyards, which offers a more sustainable strategy to prevent initial and subsequent infestations. By utilizing mark-release-recapture studies under semi-field conditions in 2022, we identified lavender essential oil and CNR-1 (a proprietary emulsifiable essential oil blend) as two potential repellents for L. delicatula adults in the context of grapevines. We further evaluated the response of adult L. delicatula to lavender oil and CNR-1 SPLAT polymer matrix formulations in highly infested vineyards during September 2022. Lavender oil significantly repelled L. delicatula in early September on Vitis hybrid 'Traminette' when compared with untreated and SPLAT control treatments. We also observed L. delicatula adults shift their preference to V. hybrid 'Traminette' over V. vinifera 'Syrah' in late September, which may be attributed to cultivar preference and/or difference in senescence timing. Here, we provide evidence that lavender essential oil could serve as an additional tool for managing L. delicatula in vineyards.","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":"144512949","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}
