Effects of Starvation on the Growth and Development of Athetis dissimilis Larvae
The research on the starvation tolerance of Athetis dissimilis larvae is helpful to understand the living habits of this insect and to better control the pest.In this study,the survival rate,growth and development of A.dissimilis larvae were measured by starvation and refeeding after starvation.The results showed that all larvae from 2-day-old to 12-day-old died after starvation treatment,and the hunger tolerance became stronger with the increase of day-old.The average survival time of 12-day-old larvae was 11.90 days after starvation treatment.After starvation treatment,64.4％of 14-day-old larvae could pupate.After the refeeding treatment,life period of 4 and 8-day-old larvae was significantly prolonged and the pupa weight was significantly decreased with the extension of starvation time.After the 12-day-old larvae were starved for a short time,the larval development time increased significantly,but the pupa weight did not decrease significantly.The results indicated that the older the larva,the stronger the ability to resist hunger,and the larva could causerepeated damage after repeated feeding.The results of this study provide a theoretical reference for the scientific control of this insect.
