Abstract:

The paper aims to study the occurrence dynamics of sorghum borer and solve the problem of appropriate control of pests. In this study, three-year field experiments were conducted to monitor the occurrence dynamics of Mythimna separata, Proceras venosatum, Ostrinia furnacalis, Conogethes punctiferalis, Spodoptera frugiperda and Chilo suppressalis on sorghum by using green control techniques such as sex pheromone. The results showed that: Ostrinia furnacalis and Proceras venosatum were the most serious pests, accounting for more than 70% of Lepidoptera pests. The occurrence period of various Lepidoptera pests was from early May to early August, mainly from the end of May to the middle and late July. This study provides support for more scientific and reasonable prediction of the occurrence and damage of Lepidoptera pests on sorghum, and also a practical basis for formulating control methods of Lepidoptera pests in local organic sorghum production.

Key words: organic sorghum, sex attractant, Spodoptera frugiperda, prediction, pest
