Abstract:
The effect of a 24-h exposure of adults of Carpophilus hemipterus to artificial diets treated on the surface with different concentrations of benzoylphenylureas, on the hatchability of eggs laid during the subsequent 14 days, was investigated. The order of persistence of sterilization at 5 ppm was chlorfluazuron (IKI-7899), 12 days > XRD-473, 10 days > diflubenzuron, 6 days > teflubenzuron (CME 134), 4 days. Three of the substances (chlorfluazuron, diflubenzuron and teflubenzuron) had no direct ovicidal effect when C. hemipterus eggs were dipped in 1000 ppm dilutions, but the larvae that hatched from the treatments died within 2 days. © 1986, Springer Science + Business Media B.V..
