Argentine Ant Control on Protea, Hawaii, 1984

Abstract

Durban 50WP and Dycarb 76WP were tested as a barrier treatment against Argentine ants foraging into protea flowers. Trees were pruned to assure no connection to the ground, except for the main tree trunk. Insecticides were applied on 17 Aug and 28 Sep around the base of the tree (1-ft radius on the ground to 1-ft above the base of the tree) with a compressed air sprayer equipped with a No. 8004 Teejet® nozzle. The experiment was arranged in a randomized complete block design with 5 trees per treatment. Flowers were harvested weekly and observed for ants.
