Biochemical mechanism of chlorantraniliprole resistance in Spodoptera litura (Fab) (Lepidoptera: Noctuidae)

“…Chlorantraniliprole belongs to new insecticide chemistries, which is highly effective against S. litura and S. frugiperda (Bentley et al, 2010;Hardek et al, 2011). Implementation of resistance management program for new class of insecticide can prolong the effective life of that insecticide (Croft et al, 1987).…”

Residual and Systemic Efficacy of Chlorantraniliprole and Flubendiamide Against Corn Earworm (Lepidoptera: Noctuidae) in Soybean

“…In contrast, flubendiamide is only labeled for foliar applications and is not known move systemically to other plant structures. Similar to chlorantraniliprole, flubendiamide has greater residual efficacy compared to other insecticides (Hardke et al 2011). Therefore, the objectives of this study were to determine the systemic and residual efficacy of chlorantraniliprole and flubendiamide against corn earworm through laboratory bioassays when applied as a foliar application to soybean.…”

Insecticide Susceptibility of Three Species of Cutworm (Lepidoptera: Noctuidae) Pests of Grapes

“…The variation in susceptibility to insecticides in species of Abagrotis is not surprising and has been reported for many other noctuids (Brickle et al 2001, Pineda et al 2004, Hardke et al 2011. However, interesting differences were detected within species between neonate and fourth-instar larvae, and responses among the different species were substantial and potentially important for the control of these cutworms in vineyards.…”
