Диапауза яблонного плодового пилильщика (Hoplocampa testudinеа Кlug) в условиях предгорного Крыма

Abstract

As a result of the observations during 1963—19&7 it was established that Hoplocam-' pa testudineae Klug, under conditions of the Crimean foothill had a two- and three-year diapause. Not less than 15% of the larvae in cocoons remain annually in a state of the two-year diapause, and from 3.7 to 5.2% in a state of the three-year diapause. The temperature and moisture of soil are basic factors affecting the duration of the diapause of the pest's larvae.
