Wheat containing adults and eggs of Graphognathus spp. was treated with a 15 ppm dichlorvos spray as it was conveyed into storage. All adult beetles were killed within 1 day after a 24-hour exposure. The treatment prevented oviposition by the adults but did not kill all the eggs that were in the wheat. Dichlorvos residues on the wheat immediately after application ranged from 1.3 to 6.8 ppm. |
