Molecular characterization and functional expression of voltage-gated sodium channel variants in Apolygus lucorum (Meyer-Dür).

Background: Apolygus lucorum (Meyer-Dür) is a serious worldwide agricultural pest, especially for Bt cotton in China. Pyrethroids, neonicotinoids and organophosphates are the most effective insecticides to control piercing and sucking insects, including A. lucorum.

Assessment of the effects of lethal and sublethal exposure to dinotefuran on the wheat aphid Rhopalosiphum padi (Linnaeus).

The wheat aphid Rhopalosiphum padi (Linnaeus) (Hemiptera: Aphididae) is a devastating pest of wheat crops worldwide. Dinotefuran, a novel neonicotinoid insecticide, has been used to prevent piercing-sucking agricultural insects, such as R. padi.

Genome Analysis of Cytochrome in Dinotefuran-Treated Apolygus lucorum (Meyer-Dür).

In this study, two CYP genes, CYP395G1 and CYP4EY1, were analyzed in Apolygus lucorum (Hemiptera: Miridae). The expression pattern in different developmental stages of both CYP395G1 and CYP4EY1 revealed that first instar nymphs possessed the highest gene-transcript levels. After 12 h of dinotefuran treatments, the expression levels of CYP395G1 increased by 1.
