AbstractAn improved cage arrangement resulted in 73% of the female European pine shoot moths being mated during a 48-hour test. Key factors were continual airflow from females to males and a light-to-dark illumination change. The ponderosa pine tip moth, Rhyacionia zozana(Kearf.), the black-headed budworm, Acleris gloverana(Wlsm.), and two species of spruce budworm, Choristoneura occidentalisFreeman and C. viridisFreeman, were also tested in the apparatus with some success in every case. |
