Abstract

Carbofuran at 2 oz AI/acre caused a 94% reduction in 3rd- and 4th-instar larvae of alfalfa weevil. There was a 67% reduction in 1st- and 2nd-instar larvae which were protected within the buds. Carbofuran did not reduce the percentage parasitism by Bathyplectes curculionis (Thomson) although the total parasitoids that developed per unit area was less.
