Biochemical and molecular analyses of insecticide resistance in greenhouse populations of Bemisia tabaci (Hemiptera: Aleyrodidae) in Türkiye
Abstract
The sweet potato/cotton whitefly Bemisia tabaci (Gennadius) (Hemiptera: Aleyrodidae) is one of the most destructive vegetable pests in greenhouses in Türkiye. While the preferred method of control primarily relies on insecticides such as neonicotinoids, organophosphates and pyrethroids, their intensive use has caused whiteflies to rapidly become resistant. Samples were collected from 13 Turkish B. tabaci greenhouse populations. Bioassays from the Marmara Region identified as high as a 53-fold increase in resistance to chlorpyrifos-ethyl, a 303-fold increase to imidacloprid and a 282-fold increase to acetamiprid. Bioassays in the Central Anatolia Region reported a 76-fold increase in resistance to deltamethrin and—15-fold increase to thiamethoxam. Most of the populations showed cross-resistance for neonicotinoids. All collected B. tabaci populations were determined to be MEAM 1 (also referred to as biotype B) for diagnostic band E0.14. The E0.14 esterase variant that helps to diagnose biotype B insects was found in all individuals from field populations. Almost all populations showed higher non-specific esterase, glutathione-S-transferase (GST) and monooxygenase activity when compared to susceptible SUD-S population. AChE insensitivity assays for individual B. tabaci suggest a target-site modification as a mechanism of resistance to chlorpyrifos-ethyl. This is the first report of AChE variants identified based on their sensitivities to chlorpyrifos ethyl-oxon and pirimicarb in Turkish B. tabaci populations. Fixed ace mutations in the target-site of organophosphates and pyrethroids were identified in six populations. Resistance to organophosphates and neonicotinoids were at least partially related to both ace mutations and insensitive AChE and monooxygenase activities, respectively. The results will help develop effective resistance management programs of B. tabaci in Türkiye.
期刊介绍：
Phytoparasitica is an international journal on Plant Protection, that publishes original research contributions on the biological, chemical and molecular aspects of Entomology, Plant Pathology, Virology, Nematology, and Weed Sciences, which strives to improve scientific knowledge and technology for IPM, in forest and agroecosystems. Phytoparasitica emphasizes new insights into plant disease and pest etiology, epidemiology, host-parasite/pest biochemistry and cell biology, ecology and population biology, host genetics and resistance, disease vector biology, plant stress and biotic disorders, postharvest pathology and mycotoxins. Research can cover aspects related to the nature of plant diseases, pests and weeds, the causal agents, their spread, the losses they cause, crop loss assessment, and novel tactics and approaches for their management.
