Increasing landscape diversity (Shannon diversity) significantly reduced pest abundance and increased the diversity of pests and predators as well as predator abundance. Predator abundance and diversity matrices played a significant role in herbivore suppression suggesting a strong top-down effect. Number of fruits was higher in triple cropping.

The WCT coconut variety exhibited moderate resistance to exotic whitefly infestation through the accumulation of boric acid. Furthermore, the activation of the biosynthetic pathway for unsaturated fatty acids, leading to increased levels of docosahexaenoic acid and arachidonic acid, played a significant role in its defense response. In WCT, the uninfested top leaves showed higher levels of shikimic acid, stearic acid, threonic acid, lactic acid, and palmitic acid, suggesting these compounds contribute to its defensive strategy. The abundance of sugars in the bottom leaves of COD likely facilitated the feeding and development of the whiteflies, making it a more favorable host for the pest. This study highlights distinct metabolic responses to whitefly resistance and lays the foundation for future research aimed at developing pest-resistant coconut cultivars.</p></div>","PeriodicalId":8409,"journal":{"name":"Arthropod-Plant Interactions","volume":"19 5","pages":""},"PeriodicalIF":1.3,"publicationDate":"2025-09-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145037035","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
