Abstract
Tomato moth larvae, both parasitized and unparasitized by the Tachinid,W. quadriPustulata were subjected to different constant humidity percentages at constant temperature during the pupal period of both host and parasite. The effects of the moisture on the length of the pupal period and the viability were noted. It was found that as the humidity incrtased the viability of the host decreased, while that of the parasite increased. Both host and parasite showed a maximum rate of metamorphosis near 73.4% humidity at 27 degrees Centigrade.This publication has 0 references indexed in Scilit:
