Imidacloprid is a largely commercialized neonicotinoid insecticide, and it is used effectively against a variety of sap-sucking insect pests including melon aphid, Aphis gossypii. In this study, the inhibitory and stimulatory effects of low and sublethal concentrations of imidacloprid were investigated on two successive generations of A....

The melon aphid, Aphis gossypii Glover (Hemiptera: Aphididae) is a major pest affecting plants of Cucurbitaceae family worldwide. Clothianidin has been broadly used for the control of this insect pest. In this study, we investigated the impact of clothianidin on the demographical traits and expression changes of vitellogenin and ecdysone...

Cytochrome P450 monooxygenases (P450s) are highly conserved multifunctional enzymes that play crucial roles in insecticide resistance development. In this study, the molecular mechanisms of P450s in acetamiprid resistance development to melon aphid, Aphis gossypii was investigated. Acetamiprid resistant (32.64-fold resistance) population...

Ecdysone receptor (EcR) plays important roles in molting, metamorphosis, and reproduction of insects. EcR ortholog and its function in melon aphid Aphis gossypii have not been documented yet. RNA interference (RNAi) is a reverse-genetic approach used to study functional genomics, but recently, it has also shown promise as a novel tool that...

The frequency and magnitude of climate extremes, especially temperature extremes (TE), are increasing, which are exposing insect populations. However, insect responses to TE are poorly understood. In this study, we investigated the impact of high-temperature (HT: 38 °C) and low-temperature (LT: 3 °C) stresses on demographic parameters and...

Stimulatory effects (hormesis) of acetamiprid on demographical traits and vitellogenin gene expression of melon aphid, Aphis gossypii Glover, were examined. The longevity and fecundity of the parental aphids (F-0) were both reduced by a low lethal concentration of acetamiprid (LC15), while no effect was observed when exposed to a sublethal...

Climate change generally influences all the living world, including insects, so all organisms cope with these stresses to survive. Temperature rise leads to increased insect pest severity, while cold acclimation helps insects to survive in temperate areas in several complex ways. The Oriental fruit fly, Bactrocera dorsalis, is one of the most...

Buprofezin, a chitin synthesis inhibitor that can be used for the control of hemipteran pests, especially melon aphid, Aphis gossypii. The impact of low lethal concentrations of buprofezin on the biological parameters and expression profile of CHS1 gene were estimated for two successive generations of A. gossypii. The present result shows that...
