Geographic susceptibility of Chilo suppressalis Walker (Lepidoptera: Crambidae), to chlorantraniliprole in China

Abstract

These results revealed great geographical variations in chlorantraniliprole susceptibilities among different geographic populations of RSSBs, which might indicate the potential for RSSBs to develop resistance to chlorantraniliprole. The effective execution of insecticide resistance monitoring programs and management strategies is urgently needed in China to sustain RSSB susceptibility to chlorantraniliprole.

Constitutive overexpression of cytochrome P450 monooxygenase genes contributes to chlorantraniliprole resistance in Chilo suppressalis (Walker)

“…SSB is difficult to control because most of its life cycle is spent inside rice stems; besides, this pest seems to have a remarkable ability to develop resistance to various insecticides . As early as the 1960s, resistance of SSB to trichlorfon, parathion, parathion‐methyl, and sumithion was recorded in Japan .…”

“…The control of SSB mainly depends on chemical insecticides. Since 2008, chlorantraniliprole has been registered in China for the selective control of Lepidoptera pests . Thus, it provides a valid measure for pest resistance management.…”

Sublethal effects of chlorantraniliprole on development, reproduction and vitellogenin gene (CsVg) expression in the rice stem borer,Chilo suppressalis

“…Chlorantraniliprole has received considerable interest because of its novel mode of action, low mammalian toxicity and high insecticidal activity against lepidopteran insects as well as some species in the orders Coleoptera, Diptera and Hemiptera . Since its introduction in China in 2008, chlorantraniliprole has been widely used to control several lepidopteran pests, including C. suppressalis …”

Molecular characterization and expression profiles of nicotinic acetylcholine receptors in the rice striped stem borer, Chilo suppressalis (Lepidoptera: Crambidae)

“…Chemical control is still the major approach used to protect rice from damage by the rice stem borer. Unfortunately, C. suppressalis has developed high resistance to organophosphate and nereistoxin insecticides due to their sustained application in the field, and the estimated cost of controlling this pest is approximately US$160 million annually (Wu et al, 2013a;Chang et al, 2014;Su et al, 2014). However, insecticides are not always effective due to the narrow window for damage control between hatching and penetration into the plant stem of rice stem larvae (Wang et al, 2014).…”
