Abstract
Directional cone-orifice traps were suitable for monitoring population densities of five Lepidoptera species, provided the captured moths were removed from the traps on a regular basis of at least once a week throughout the flight period. Omni-directional traps with circular screen barriers in the entrance area and a slow-release insecticide in the receiver to kill the captured moths functioned well over extended periods of unattended use. These traps would be useful for monitoring and mass trapping purposes. Similar traps without the circular screen barriers were less efficient but, due to their simplicity, they would also be suitable for monitoring purposes. The optimum quantity of pheromone per dispenser was the same for the directional cone-orifice and omni-directional traps.This publication has 13 references indexed in Scilit:
