Description
Summary:Six insecticides commonly used on cabbage were tested at the lowest recommended label rates. Each insecticide was dissolved in 30 ml acetone. Five ml of the solution was pipetted into a 1700 mm2 glass vial and distributed on the inside surface by swirling for 1 minute. The solution was poured out and the vials were dried under a ventilation hood for 4 hours. Fifteen replicates vials were prepared for each insecticide. DBM collected from a cabbage field at Kula, Hawaii were used to initiate a laboratory culture. Five to ten 7-day old fourth generation adults were placed in each treated vial. Adults were confined in the vial by a piece of organdy secured with a rubber band. Mortality was determined 4, 8, and 24 hours after introduction. Individuals were counted as dead when no movement was observed as the vial was gently shook.
