Sequence alignment and phylogenetic tree analysis showed that GmolOR7 is closely related to Cydia pomonella OR54, with the amino acid sequence identity of 80.21%. Furthermore, the different developmental stages and tissues of GmolOR7 in G. molesta were analyzed by real-time quantitative polymerase chain reaction. The results demonstrated that GmolOR7 was expressed at higher levels in adults, and particularly in the antennae of females. GmolOR7 expression was the highest in 3-d-old adults.

In this study, we collected related data on C. sasakii, the market price of jujube, and costs of its prevention and management. The potential economic losses of China's jujube industry caused by C. sasakii were predicted using @RISK (Palisade, Raleigh, NC) software and a stochastic simulation method, which is the universal model of potential economic loss assessment for economically important fruit flies. Our results showed that the total economic losses potentially caused by C. sasakii to China's jujube industry are approximately 8,643.41–350,524.15 million RMB (RMB is the legal tender in China; approximately 1,338.00–54,261.14 million USD) if the pest was not managed and approximately 2,487.15–123,242.12 million RMB (about 385.01–19, 077.88 million USD) when management was applied. Therefore, a loss of approximately 841.83–244,144.06 million RMB (approximately 130.32–37,793.50 million USD) can be logically retrieved after controlling this pest. As a result, we suggest that related organizations and pest management practitioners strengthen prevention and control measures of C. sasakii to reduce the risk of economic loss by decreasing the infestation level of C. sasakii in jujube production and, thus, economic losses after infestation.","PeriodicalId":15765,"journal":{"name":"Journal of Entomological Science","volume":null,"pages":null},"PeriodicalIF":0.9,"publicationDate":"2023-04-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43390702","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Citrus mealybug causes direct plant damage when feeding on plant leaves, stems, flowers, and fruits, and this damage can result in substantial economic losses. Insecticides are used to manage citrus mealybug populations in greenhouse production systems. Although entomopathogenic fungal-based insecticides are labeled for use against citrus mealybug, there is no quantitative information on their efficacy against this insect pest under greenhouse conditions. Consequently, four experiments were conducted in a research greenhouse at Kansas State University (Manhattan) from 2020 to 2022 to determine the efficacy of three commercially available entomopathogenic fungal-based insecticides on citrus mealybug feeding on coleus, Solenostemon scutellarioides (L.) Codd (Lamiales: Lamiaceae), plants: Beauveria bassiana strain GHA (BotaniGard®, Laverlam International Corp., Butte, MT), B. bassiana strain PPRI 5339 (Velifer™, BASF, Research Triangle, NC), and Isaria fumosorosea Apopka strain 97 (Ancora®, OHP, Inc., Bluffton, SC). The surfactant polyether and polyether-polymethylsiloxane-copolymer (CapSil®, Aquatrols, Paulsboro, NJ) was added to spray solutions to determine whether the surfactant would enhance efficacy. The entomopathogenic fungal-based insecticides, with or without the surfactant, were not effective in managing citrus mealybug populations, with <50% mortality in all four experiments. Our study indicates that entomopathogenic fungal-based insecticides are not effective in managing citrus mealybug populations in greenhouses.","PeriodicalId":15765,"journal":{"name":"Journal of Entomological Science","volume":null,"pages":null},"PeriodicalIF":0.9,"publicationDate":"2023-04-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47446512","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The cumulative percentage of emerged larvae at 24 h and 48 h posttreatment was recorded as a measure of response to the hot air treatment. In the untreated control, which was exposed to room temperature (26 ± 2°C), the cumulative emergence of larvae at 48 h was 99.2 ± 1.7%. The cumulative percentage of larval emergence at 48 h ranged from 97.2% at 87 ± 2°C to 67.7% at 147 ± 2.4°C. The biological efficacy of this proposed hot air treatment was, thus, not acceptable.

We studied the interaction of trifluralin and earthworms, Eisenia foetide Savigny (Annelida: Lumbricidae), to provide additional information for assessing the risk of trifluralin to ecological safety in soils. Contact toxicity assays established median lethal concentrations (LC50) of 726.298 µg/L at 24 h, 418.783 µg/L at 48 h, and 82.007 µg/L at 72 h of exposure to trifluralin. Within 24 to 48 h of exposure to trifluralin, antioxidant activity (e.g., superoxide dismutase, catalase, peroxidase) increased in vivo, but by 72 h of exposure the activity was inhibited and, at high concentrations of trifluralin, death occurred. Based on the activity of glutathione S-transferase (GST) and multifunction oxidase (MFO), it appears that GSTs may be involved in the detoxification of trifluralin in vivo, and that MFOs may be the key detoxification enzymes involved. Earthworm degradation of trifluralin shortened the half-life of trifluralin in soil by as much as 1.78 d.
