Abstract

The pheromone-based trapping is a prerequisite in determining the population dynamics of a pest, which in turn helps to take up suitable management practices. The specific sex pheromone traps were used to monitor the adult male population of pink bollworm, Pectinophora gossypiella (Saunders) in the Main Agricultural Research Station, Raichur, Farmer field and also at cotton ginning mills in Raichur. The lures of traps were changed at an interval of 60 days and data were collected weekly. The attraction of male moths of PBW started, at the beginning, of the first week of September and continued till the third week of April at the Main agriculture research station, Raichur and also in the Farmer field whereas, in cotton ginning mills the activity seen throughout the year. The peak catches of the pink bollworm were observed during the last week of December in the Main agriculture research station, Raichur (31.49/trap/week). Whereas in farmer fields peak catches were observed during the second week of January (34.36/trap/week).

Conclusion

The activity of pink bollworm moths monitored through sex pheromone traps from June 2017-April 2018 indicated that the activity of moths started from September and continued till the end March. It clearly indicates that the control measure should be initiated from September with all available suitable methods to manage pink bollworm effectively.
