Abstract
Response of male San Jose scale, Quadraspidiotus perniciosus (Comstock), to female produced and synthetic sex pheromones was studied in Washington and California. Males responded equally well to two isomers of pheromone at rates of 33–900 μg/trap. Pheromone cap loads of 100 μg were more attractive than 300 virgin female scales on gourds. Simplified trap designs were evaluated with synthetic pheromone caps, and were comparable in male collections to the standard 473-ml carton traps normally used with virgin females. Observations of males in the field indicated a lower flight threshold temperature of ca. 17°C, and active flight at wind velocities of less than 1.8 m/sec (4.0 mph). In greenhouse tests, most males responded to pheromones at light values between 4.6 and 32.5 lux.This publication has 3 references indexed in Scilit:
