Abstract:

Azinphosmethyl and methyl parathion applied at 0.125 pound per acre left greater deposits and caused higher mortality of Anthonomus grandis Boheman on frego than on normal bract cotton squares when: (1) weevils were caged in the field on the 2 types of cotton, (2) weevils were placed in 1-pint cartons with squares removed from the plant after spraying, and (3) when weevils were placed in cartons with squares sprayed after being picked from the plant. These results were confirmed by recovery of approximately 7 times the amount of residue from frego than from normal bract buds sprayed with methyl parathion.
