| Abstract: | Based on the morphological characteristics of larva ,pupa and egg of Taiwan rice stem borer Chilotraea auricilia (Dudgeon), the standards for differentiating the instars of larvae and developmental grades of pupae and eggs were determined,and an occurrence time forecast method of this insect pest was proposed by combining the grading standards with the common durations of various stages/instars/grades tested indoor in Nanning condition. After 3 years verifications on 19. 3 thousand hm2 of rice fields,the mean accuracy of the occurrence time forecast was up to 96. 7%,and the mean control effect in accordance with the forecast reports was 85. 8%. |
