Abstract

Vegetable leafminers, Liriomyza sativae Blanchard, were reared from `2-14' celery foliage held at different constant temperatures to determine the influence of temperature on pupal development and on host and parasite emergence. Significantly (P@?0.05) greater numbers of leafminer pupae were obtained from celery leaflets held at 32.2@*C than at 15.6@*C. The percent emergence of adult leafminers was significantly greater (P@*0.05) at the higher rearing temperature (75% emergence above 20@*C and 45% emergence below 20@*C). Larval parasite emergence (Diglyphus intermedius (Grit.) and Chrysonotomyia formosa (Westwood)) was significantly (P@?0.05) greater at temperatures below 23@*C (43%) than at higher temperatures (29%). Leafminer pupal developmental time under constant rearing temperatures increased from 5-7 days at 32.2@*C to 21.0 days at 15.6@*C. Pupal development required a mean 127.8 degree-days, with an estimated lower threshold temperature of 10.0@*C. The degree-day requirements for pupal development were not significantly different at constant rearing temperatures of 15-35@*C.
