説明

The effect of temperature on the longevity and feeding frequency of adults of the Fruit Sucking Moth, Oraesia emarginata FABRICIUS was investigated at constant temperatures from 8°C to 29°C at a photoperiod of 15L-9D. The mean longevity was maximum (about 100 days) at 14°C and gradually decreased as temperature rose or tell (30 days at 29°C and 17 days at 8°C). Males survived 6 to 12 days longer than females above 17°C. There were no sex-related differences below 14°C. Feeding was most frequent at 20°C in males and at 17°C in females. The frequency gradually decreased as temperature diverged and was almost zero at 8°C. The number of days when moths showed feeding activity was 8 to 11 days longer in males than in females above 17°C. Below 14°C no difference was found between the sexes. The ratio of feeding days to longevity increased gradually with rising temperature and peaked at 26°C. There was no difference in feeding frequency between virgin females and mated females at 26°C. There is a high correlation between feeding frequency and early night temperature (from 18:00 to 22:00) under natural conditions. The regression equation predicts that the critical temperature for feeding is 11°C.
