“…Thiamethoxam, another neonicotinoid pesticide, affected the feeding behavior of soybean aphid A. glycines by shortening the phloem ingestion and prolonging the duration of non-probing events (Stamm et al, 2013). Dinotefuran exerted an effect on the proportion of non-probing, the pathway activity and phloem-feeding patterns of M. persicae (Seo et al, 2009). In the present study, cycloxaprid caused various effects on A. gossypii feeding behaviors.…”

Aphis gossypii Glover (Hemiptera: Aphididae) is a key pest in cotton crops, notably owing to its increasing resistance to commonly used pesticides. Such resistance prompts for the development of integrated pest management (IPM) programs that include novel pesticides being effective against the aphid. In the present study, we assessed lethal and sublethal effects of cycloxaprid, a novel chiral neonicotinoid pesticide developed in China, on A. gossypii. The lethal concentration at 50% (LC ) value of cycloxaprid on A. gossypii was estimated, using the dipping method, at 7.73 mg/L. The impact of a sublethal concentration (LC ) and a lethal concentration (LC ) of cycloxaprid on A. gossypii population growth and feeding behavior (using electrical penetration graph technique [EPG]), and its transgenerational effect were further assessed. Adult longevity and fecundity significantly decreased after exposure to LC or LC of cycloxaprid. Cycloxaprid with sublethal concentrations (especially LC ) had negative effects on phloem ingestion by A. gossypii. Additionally, the offspring of the adults exposed to LC of cycloxaprid had shorter nymphal development duration and adult longevity than the control, and those from LC and LC treatments had lower adult fecundity and net productive rate. We demonstrated that cycloxaprid is a pesticide showing both lethal and sublethal activities, and transgenerational effects on A. gossypii; it may be useful for implementation in IPM programs against this aphid pest.
