Reproductive biology of the European pine shoot moth Rhyacionia buoliana (Schiffermüller) (Lepidoptera : Olethreutidae), with special reference to mating behavior, sex attraction, and fecundity

Creator:: Daterman, Gary E.
Abstract:: Major objectives of the study involved development of a laboratory procedure to obtain mating, determining characteristics of female sex attraction, and determination of the effects of temperature and humidity on mating and fecundity. The second of two methods devised to obtain mating, "the vertical airflow technique," was convenient to employ...
