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....

Climate change and global trade are two main drivers of shifts in the distribution of invasive insect pests. The Oriental fruit fly, Bactrocera dorsalis Hendel, is one of the most economically important invasive pests having detrimental effects on several vegetables and fruits. This highly invasive species originating from mainland Asia has now...

Cytochrome P450s (CYPs) genes are associated with insecticide resistance through overexpression and detoxification mechanisms in several insect-pest species. However, little is known about the role of P450s genes and their response to clothianidin resistance development in cotton-melon aphid, Aphis gossypii, a serious crop pest. In this study,...

Clothianidin is a second-generation neonicotinoid insecticide, widely used against sap-sucking insect pest including melon aphid,Aphis gossypiiGlover (Hemiptera: Aphididae). This pest causes severe economic damage to Cucurbitaceae plants worldwide. In this study, we investigated clothianidin resistance development under continuous selection...

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...

In agroecosystems, insects have to compete with chemical insecticides, which are frequently present at sublethal concentrations. The exposure of insects to these modest stresses is now well-established to generate hormesis effects, which has implications for controlling insect pests. In this study, we assessed the sublethal effects of...

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...

The bird cherry-oat aphid, Rhopalosiphum padi (L.) (Hemiptera: Aphididae) is one of the most economically important pests of wheat crops worldwide. Thiamethoxam, bifenthrin, and flonicamid are extensively used insecticides for controlling this key pest. However, the indiscriminate use of chemical insecticides has led to the development of...

The green bug, Schizaphis graminum Rondani (Hemiptera: Aphididae), is a major pest of wheat plants through direct feeding and indirectly by transmitting several viruses around the world. Insecticides including thiamethoxam, bifenthrin, and flonicamid, are widely used to control this pest. However, indiscriminate chemical applications cause...

The chive maggot, Bradysia odoriphaga Yang and Zhang (Diptera: Sciaridae) is an economically important insect pest, affecting many important vegetables, including Chinese chive, especially in northern China. Clothianidin is a second-generation of neonicotinoid insecticide that is currently used for the management of B. odoriphaga. In the...

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...

Climate change and biological invasions of insect pests are interlinked global concerns that drive shifts in the distribution of invasive insects. The peach fruit fly, Bactrocera zonata Saunders, is one of the most economically important Tephritidae species that attack several host plants and causes serious damage in Asia and Africa. Currently,...

The chemical application is considered one of the most crucial methods for controlling insect pests, especially in intensive farming practices. Owing to the chemical application, insect pests are exposed to toxic chemical insecticides along with other stress factors in the environment. Insects require energy and resources for survival and...

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...

In agroecosystems, insects contend with chemical insecticides often encountered at sublethal concentrations. Insects' exposure to these mild stresses may induce hormetic effects, which has consequences for managing insect pests. In this study, we used an electrical penetration graph (EPG) technique to investigate the feeding behavior and an...

Thiamethoxam, a second-generation neonicotinoid insecticide is widely used for controlling sap-sucking insect pests including Rhopalosiphum padi. The current study aimed to investigate the life-history parameters and feeding behavior of R. padi following treatments with sublethal concentrations of thiamethoxam. The lethal concentration 50...

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...

Insects are vital arthropods that significantly impact various ecosystems. Their successful colonization of diverse habitats spanning from cold to warm environments is made possible by numerous adaptations shaped by environmental selection. This comprehensive review delves into the spectrum of physiological adaptations exhibited by insects to...

Flonicamid is a novel systemic insecticide that efficiently controls sap-sucking insect pests. However, the impact of sublethal concentrations of flonicamid on key demographic parameters and the feeding behavior of greenbug, Schizaphis graminum has not yet been studied. In this study, we used the age stage, two-sex life table approach, and...

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.
