Abstract: | Summary The problem of arrested or delayed development was examined in the sugar cane borer,Diatraea saccharalis. It was found that the insect can either enter diapause or exhibit a period of delayed metamorphosis according to the photoperiod conditions prevailing. We have observed the development characteristics ofD. saccharalis and conclude that a distinction should be made between a delayed metamorphosis phase and a diapause stage.This work was supported by a grant from NSERC. |
