In this study, we investigated the effects of 5 different concentrations of Ca(NO3)2 (0, 2, 4, 6, and 8 mM) on cotton plants and the performance of Aphis gossypii. Our results demonstrated that nitrogen application significantly enhanced the growth indices of cotton seedlings (eg plant height, aboveground fresh weight) and plant biochemistry parameters (eg nitrogen, chlorophyll, and tannin). Nitrogen also affected the life history parameters of A. gossypii (eg longevity, reproductive days, fecundity, intrinsic rate of increase, finite rate of increase, and net reproductive rate). Notably, the positive effects on cotton seedling growth and A. gossypii performance observed at the 6 mM level diminished at the 8 mM level. Additionally, the highest soluble sugar content was observed in the unfertilized plants (the 0 mM treatment). Electrical penetration graph analysis revealed that A. gossypii spent less time on intercellular probing and more time feeding on phloem with increasing nitrogen levels, suggesting improved nutrient acquisition from phloem, which supported the observed increase in fecundity. The above results indicate that the bottom-up effects of nitrogen fertilizer could trigger outbreaks of A. gossypii. These findings provide a scientific basis for optimizing nitrogen fertilizer within integrated pest management programs so as to protect yields, reduce the risk of aphid outbreaks, as well as the costs for labor and ecological environment.</p>","PeriodicalId":94077,"journal":{"name":"Journal of economic entomology","volume":" ","pages":"1225-1234"},"PeriodicalIF":0.0,"publicationDate":"2025-06-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144060724","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}

Synthetic insecticides are commonly used to manage these pests. However, developing effective biological control methods is essential to reduce reliance on chemical insecticides and their associated impacts. Entomopathogenic nematodes (EPNs) are effective biocontrol agents used against various lepidopteran and coleopteran pests in different cropping systems. The objectives of the current study were to identify the naturally abundant EPNs in pecan orchards and evaluate their effectiveness against fall webworm, walnut caterpillar, and nut curculio. EPNs were recovered from all sampled orchards. However, 46.43% of the samples were positive for the presence of EPN, which were identified to 5 EPN species, Heterorhabditis indica, H. zealandica, Metarhabditis rainai, Oscheius myriophilus, and Steinernema glaseri. Additionally, the effectiveness of these local EPNs was compared with 2 commercial EPN strains, H. bacteriophora (HP88) and S. carpocapsae (All). Laboratory assays indicated that H. indica and H. zealandica have high virulence against both the larvae and pupae of fall webworm, walnut caterpillar, as well as larvae of nut curculio. In contrast, M. rainai, O. myriophilus, and S. glaseri exhibited low virulence against the larvae of fall webworm and walnut caterpillar.

We asked whether feeding bumble bees sunflower pollen diets prior to pathogen exposure decreases Crithidia infection compared to buckwheat pollen (Fagopyrum esculentum Moench; Polygonales: Polygonaceae). Buckwheat pollen was used as a comparison since it has a similar protein concentration as sunflower pollen, but results in higher Crithidia counts more comparable to typical wildflower pollen when consumed post-infection. Bumble bees were fed sunflower or buckwheat pollen for 7 d, inoculated with Crithidia, and then fed a wildflower pollen control diet for seven more days before assessing infection. We found that consuming a sunflower pollen diet before inoculation did not reduce Crithidia cell counts compared to buckwheat pollen. Furthermore, bumble bee survival and consumption of sucrose solution and pollen did not differ between these diets.
