Abstract
Development of the artichoke plume moth, Platyptilia carduidactyla (Riley), was studied at several constant laboratory temperatures ranging from 7°C–31°C. The lower developmental thresholds for egg stage, 4 larval Instars, and pupal stage were determined from the linear relationship between temperature and rate of development. The 4 larval instars showed a declining trend in developmental threshold as their values decreased from 8.7°C for 1st instar to 1.5°C for 4th. Thermal units required for development from egg to adult were 476.2 C°-days in the laboratory and 502.5 C°-days in the field at a base temperature of 7°C. Fecundity In the laboratory was reduced at lO°C and 28°C and maximum fecundity attained at 19°C. Survival period of adults decreased as temperature increased.This publication has 0 references indexed in Scilit:
