We focus on the woolly whitefly, <i>Aleurothrixus floccosus</i>, and its parasitoid wasp, <i>Cales noacki</i>, used for biological control. This research is motivated by the challenges of managing whitefly populations, intensified by the limitations of pesticides and the increasing prevalence of whitefly infestations in new regions worldwide. Our findings reveal that parasitism by <i>Cales noacki</i> prolongs the development time of woolly whiteflies when the whitefly eventually overcomes the parasitoid. Wasps emerging from the fourth instar of the whitefly nymphs were larger and had higher reproductive potential than those emerging from earlier instars. We found a positive correlation between wasp size and the number of eggs in the ovary for wasps emerging from the third instar of the whitefly nymphs. However, no such correlation was found for wasps emerging from the fourth instar. Additionally, competition between whiteflies and other common pests, such as citrus mealybugs and citrus mites, seemed to hinder the emergence success of whiteflies, suggesting that multi-pest interactions could affect biological control strategies. These results demonstrate the complex life-history interactions between woolly whiteflies and their parasitoid wasps, pointing to the importance of integrating ecological considerations into pest management practices. Understanding these dynamics is important for developing effective control methods, especially in the face of global climate change, which might further reduce the efficiency of parasitoid wasps.</p>\u0000 </div>","PeriodicalId":14987,"journal":{"name":"Journal of Applied Entomology","volume":"149 4","pages":"549-557"},"PeriodicalIF":1.7,"publicationDate":"2025-01-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143831092","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}

However, our own greenhouse experiments revealed that ‘GL Sunrise’ was not resistant to PNYDV but showed a similar susceptibility such as other common varieties, for example, ‘Fuego’. Therefore, we suspected varietal host traits were affecting the reproductive potential of virus vector species with reduced virus transmission, probably explaining the empirical superior health status in the field.

Furthermore, vector abundance assessments in multisite varietal showed <i>A. pisum</i> as the predominant species. In overall cross-year and -site evaluation, early aphid census in ‘GL Sunrise’ at growth stage BBCH 61–65 indicated significantly lower primary <i>A. pisum</i>-infestation pressure (factor 0,43 relative to ‘Fuego’).

These results support the hypothesis of ampelovirus assistance towards vitivirus during transmission. Transmission experiments with <i>P. corni</i> and different GLRaV-4 strains showed a single transmission of strain 5. No transmission was observed with <i>P. persicae</i> after acquisition on GLRaV-1, -3 and GVA coinfected source vines. <i>P. corni</i> L2 collected from an infected vine and placed on a nonhost plant tested positive for GLRaV-1 and -3 until at least 30 and 50 days, respectively. These results contrast with the few days retention times generally reported in mealybugs. More work is needed to determine whether virions are conserved and, if so, their location inside the insects.</p>","PeriodicalId":14987,"journal":{"name":"Journal of Applied Entomology","volume":"149 3","pages":"405-416"},"PeriodicalIF":1.7,"publicationDate":"2024-12-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/jen.13387","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143629756","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
