Effect of Capsicum frutescens L. (Solanaceae) Aqueous Pod Extract against Aphis craccivora (Homoptera: Aphididae)

Abstract

The present study highlights the effects of aqueous pod extract of Capsicum frutescens ("Kochchi") as a soil drench and foliar spray on host location, survival and reproduction of Aphis craccivora infesting Yard-long bean plants. The findings showed that the extract negatively affected the survival and reproduction of females via the systemic activity when applied as a soil drench. Maximum reduction in survival and nymphal production were 50% and 86%, respectively. Moreover, foliar application of the extract served as the repellent against host location and opposition deterrent of A craccivora. The findings indicated that extract of Capsicum frutescens ["Kochchi could be used as an alternative candidate for synthetic chemicals for the management of A craccivora in Integrated Pest Management systems.
