We investigated effects of feeding on novaluron-treated foliage on reproductive success of Colorado potato beetles. Exposure to novaluron did not affect the number of eggs produced by females. However, the hatch rate of those eggs was signficantly reduced compared to the eggs laid by control females.

Species 1: Coleoptera Chrysomelidae Leptinotarsa decemlineata (Colorado potato beetle)
