The family Chrysomelidae represents one of the most economically and ecologically important groups within Coleoptera, with species acting as agricultural pests and contributing substantially to biodiversity in arid regions. Based on bioclimatic, topographic, and vegetation data, the current and future distributions of 4 chrysomelids (Caryedon acaciae (Gyllenhal, 1833), Chaetocnema pulla Chapuis, 1879, Phyllotreta cheiranthi Weise, 1903, and Spermophagus sericeus (Geoffroy, 1785)) in Saudi Arabia were predicted using MaxEnt modeling for 2050 under 2 Shared Socioeconomic Pathways (SSPs), SSP126 (low emission) and SSP585 (high emission) scenarios. The leaf beetle models showed strong performance, with average area under the curve (AUC) values ranging from 0.86 to 0.96 and average TSS values ranging from 0.52 to 0.65. Five predictors were chosen for each species from 21 environmental variables. The results show that the key ecological factors that influence species distributions varied, with vegetation being the most influential. According to habitat suitability maps, in the future, such distribution will be severely altered, mostly by climate change. More precisely, C. acaciae will face minor range shifts, while C. pulla, P. cheiranthi, and S. sericeus will expand their ranges substantially, especially in the Eastern Province. Our results confirm the importance of implementing adaptive pest-management strategies to address the potential range expansions of various agricultural pests, which could intensify local ecological challenges and pose a heightened threat to agricultural systems.","PeriodicalId":94077,"journal":{"name":"Journal of economic entomology","volume":" ","pages":"600-613"},"PeriodicalIF":0.0,"publicationDate":"2025-04-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143558803","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}

Harmonia axyridis (Pallas) (Coleoptera: Coccinellidae), an invasive predator, significantly impacts native predators through IGP in certain countries. Pyemotes zhonghuajia (Yu, Zhang & He) (Prostigmata: Pyemotidae), a small ectoparasitoid, parasitizes various pests from the orders Lepidoptera, Coleoptera, and Hemiptera. Although both natural enemies are essential in controlling pests like Neotoxoptera formosana (Takahashi) (Hemiptera: Aphididae), their interactions and effects on pest management remain poorly understood. The study investigates the functional response of H. axyridis to N. formosana, the lethal ability of P. zhonghuajia against N. formosana, and how intraguild interactions affect the mortality rates of both N. formosana and H. axyridis when exposed to P. zhonghuajia. Our findings revealed that H. axyridis exhibited a Holling type II functional response to N. formosana, with female adults being the most effective predators. Pyemotes zhonghuajia demonstrated significant lethality against N. formosana, particularly at higher mite densities. However, the presence of P. zhonghuajia also increased the mortality rate of H. axyridis, highlighting a parasitism-driven intraguild interaction in which the mite dominates the predator. These results challenge conventional views of predator-parasitoid dynamics and highlight the complexity of interactions among natural enemies in pest control systems.","PeriodicalId":94077,"journal":{"name":"Journal of economic entomology","volume":" ","pages":"505-513"},"PeriodicalIF":0.0,"publicationDate":"2025-04-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143477269","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}

To proactively prepare for this possibility, 12 US-registered formulations and 1 experimental formulation were assessed in the laboratory for efficacy against O. hyalinipennis, using both contact and ingestion bioassays. Six formulations, consisting of acephate, dinotefuran, flupyradifurone, and imidacloprid with initial efficacy against O. hyalinipennis were used for subsequent dose-response bioassays.

Outbreaks of the A. goyerana have been isolated to southeastern Louisiana, where they have caused reduced growth, crown dieback, and limited tree death. However, aerial detection surveys indicated that severe defoliation by A. goyerana has been affecting wetlands further east within the region. Given the possibility of expanding outbreaks, it is important to understand the timing of A. goyerana activity, duration of the flight period, and efficacy of different trap types to guide survey efforts. We deployed traps in a paired design, one bucket trap and one delta trap, each baited with synthetic A. goyerana sex pheromone at 30 sites throughout the range of baldcypress. Over 2 field seasons, we checked traps weekly and quantified the number of A. goyerana caught per trap type, ability of each trap type to detect a single moth (trap sensitivity), and growing degree days, using a base temperature of 5 °C accumulated at the onset, peak, and cessation of the flight period. We found that delta traps caught more moths but sensitivity of traps was equal between the 2 trap types. Analyses of phenology indicated that A. goyerana flight occurred between ~1,000 and 1,600 growing degree days. Optimizing trapping practices for A. goyerana may improve detection of endemic populations and help identify areas potentially at risk of experiencing outbreaks.","PeriodicalId":94077,"journal":{"name":"Journal of economic entomology","volume":" ","pages":"635-645"},"PeriodicalIF":0.0,"publicationDate":"2025-04-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143071310","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}

Additionally, we compared adult C. capitata performance under environmental chamber and outdoor conditions to determine if temperature and humidity as simulated in the chambers resulted in similar performance outcomes for the insects as being outdoors. Male C. capitata under the 10 °C range treatment had higher survival probability at 55 d postemergence compared to the constant temperature regime, while females showed no significant differences in survivorship among temperature regimes.

In 2019 and 2020, shothole leafminers caused high levels of damage to oak trees in several states in the mid-Atlantic region. The objectives of this study were to compare oak shothole leafminer damage on the genus Quercus L. (Fagales: Fagaceae) including northern red oak (Quercus rubra L), chestnut oak (Q. montana Willd.), white oak (Q. alba L), scarlet oaks (Quercus coccinea Münchh.), and to fill critical knowledge gaps of oak shothole leafminer biology. Leaf area reduction, percent damaged leaves, foliage transparency, and crown dieback were calculated to compare damage experienced by the different oak species. Emergence and Malaise traps were used to assess adult population sizes. Chestnut oak was consistently the oak species with the least leaf area reduction and foliage transparency. The injuries on chestnut oak leaves were primarily small and uniform holes (\"shotholes\") due to this leafminer. In contrast, northern red oak and scarlet oaks showed high susceptibility. Damaged leaves of these species frequently were deformed or incomplete, and the shotholes varied in size, resulting in greater leaf area reduction. Experiments showed that the conspicuous shothole damage caused by this leafminer is related to puncturing by the female flies into leaves of young buds. In conclusion, oak shothole leafminer is a native cryptic pest and outbreaks are visually apparent only when emergence coincides with oak bud and early leaf development.","PeriodicalId":94077,"journal":{"name":"Journal of economic entomology","volume":" ","pages":"770-779"},"PeriodicalIF":0.0,"publicationDate":"2025-04-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143627071","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}

Effective management of D. antiqua has historically relied on insecticide seed treatments, with spinosad being among the most commonly used options. However, declining control efficacy observed on a New York onion farm over several years raised concerns about the potential development of insecticide resistance. The purpose of this research was to (i) evaluate the efficacy of spinosad seed treatment in managing D. antiqua in the affected field from 2021 to 2024 and (ii) to assess the population's susceptibility to spinosad using a laboratory bioassay. Results from field trials revealed that the percentage of control of D. antiqua using spinosad seed treatment relative to a noninsecticide treatment declined from 51% in 2021 to -83% in 2024. Laboratory bioassay results showed an increase in LC50 values from insects collected from nontreated and spinosad-treated plants in 2023. These results document the first case of reduction in spinosad seed treatment efficacy in D. antiqua that has practical consequences for pest control (practical resistance).
