The direct impingement of insecticides on Anthonomus grandis Boheman was determined by affixing the weevils to toothpicks and placing them in the target area prior to insecticidal applications. While affixed to the toothpicks, the weevils lived in the field for approximately 7 days. Fluorescent particles were agitated with the insecticides and the size of spray droplets was calculated indirectly by the number of fluorescent particles that impinged on each weevil. Mortality occurred when the sum total of droplets, regardless of size, that impinged upon a weevil carried 4 or more fluorescent particles. |
