Sublethal effects of neonicotinoid insecticide on calling behavior and pheromone production of tortricid moths

摘要: In moths, sexual behavior combines female sex pheromone production and calling behavior. The normal functioning of these periodic events requires an intact nervous system. Neurotoxic insecticide residues in the agroecosystem could impact communication through alteration this study we assess whether sublethal concentrations neonicotinoid thiacloprid, that competitively modulates nicotinic acetylcholine receptors at dendrite, affect adults three economically important tortricid moth pests; Cydia pomonella (L.), Grapholita molesta (Busck), Lobesia botrana (Denis & Schiffermuller). Thiacloprid significantly reduced amount C. females LC0.001 (a lethal concentration kills only 1 105 individuals), altered its period LC1, both cases effect was dose-dependent. other two species similar but started higher LCs, relatively small L. botrana. Pheromone pomonella, with a reduction major compound, codlemone, one minor component, starting LC10. Since pheromones neonicotinoids are used together management species, our results have implications regarding interaction between pest control methods.
