Title: The effects of some factors on the diapause induction of Asian corn borer ( Ostrinia furnacalis )
Abstract: This paper deals with the effects of food,temperature and photoperiod on the diapause of Asian corn borer, Ostrinia furnacalis (Guene'e).The results showed that the effects of different food on the diapause induction of Asian corn borer were significantly different.The sensitivity of diapause induction by photoperiod of the larvae fed by corn ear was stronger than that of the larvae fed by cotton boll.To some extent,higher concentration of soluble sugar in the food promoted the induction of larval diapause,while higher concentration of protein suppressed it.Higher temperature was favorable to suppress the induction of larval diapause,while lower temperature was favorable to the induction of diapause.There were not determined sensitive stages of larval diapause induction by short photoperiod,but the population was more sensitive in 2 and 3 instars.The induction effects by short photoperiod were additive.
