Abstract

The population fluctuation of important lepidopteran pests was studied from July, 2013 to December, 2019 at College of Agriculture, Anand Agricultural University, Vaso, Gujarat through sex pheromone trap. Based on moth catches in pheromone traps, Helicoverpa armigera male moth activity found around the year except 13th SMW of March as well as 14th and 16th SMW of April. The higher moth catches were found during September to December with peak in the month of October. Male moth catches of Spodoptera litura was observed in pheromone traps throughout the year, however, higher moth catches were found during July to December with peak in the month of October. In case of Scirpophaga incertulas male moth catches were found from 21st to 52nd SMW. The higher moth catches of S. incertulas was found during August to October with peak in the month of October. Therefore, these results from the activities of the main lepidopteran pests will satisfy the fundamental requirement for the development of successful integrated pest management strategies.

Conclusion

The population fluctuation study on major lepidopteran pests through moths caught in respective sex pheromone trap revealed that the relatively higher male moth catches of H. armigera, S. litura and S. incertulas found during July to December, September to December and August to October, respectively with peak in the month of October. Hence, one can keep watch on the host crop of the pests grow during this period and take prompt action by adopting suitable integrated pest management tools.
