Abstract
Three greenhouse experiments were established in the Adjuntas substation of the Agricultural Experiment Station, University of Puerto Rico, to evaluate the action of fluvalinate aquaflow (Minadox) and permethrin 3.2 E.C. (Pounce) in controlling the coffee leaf miner at different life stages: larvae, pupae and moths. Data were recorded on the percentage control (P.C.) and percentage mine increase treated with fluvalinate aquaflow at three dosages (0.21, 0.42 and 0.64 ml/500 ml water) and permethrin at 1 ml/500 ml water. Permethrin at 0.64 ml (388 ml/ha) controlled 84.1% leaf miner larvae and pupae 7 days after application and 87.1% 15 days after application, respectively. Fluvalinate aquaflow also demonstrated its properties to control leaf miner moths effectively. Fluvalinate at rates of 200 and 300 ml/ha (0.42 and 0.64 ml/500 ml water) permitted mine increase in the order of 6.3 and 0%, respectively. The check treatment (no insecticide) and permethrin gave 23.7 and 18.1% mine increase, respectively. Both insecticides decreased leaf miner population.
