Abstract

The intensity of diapause of field-collected diapausing larvae of Cliilo partcllus (Swinhoe) and Cliilo oriclmlcocilielltis Strand (Lepidoptera: Pyrnlidae) was compared in the laboratory at 28 ± 0.5°C under a photopcriod of 12:12 (L:D)h. Chilo partcllus terminated diapause faster than C. oriclmlcociliellus. Mean time to diapause termination was 9.7 days for C. parlellus and 14.4 days for C. oriclinlcociliellns. Male and female C. parlellns larvae terminated diapause and adults emerged at the same time, while significant differences were found in diapause termination and in emergence times between male and female C. orichnlcocilk'llits. © 1999 ICIPE.
