Evaluation of Developmental and Reproductive Potential of Lysiphebus ambiguus (Braconidae: Hymenoptera)

Humayun Javed and Muhammad Afzal

Abstract

This study was conducted to find out the developmental and reproductive potential of Lysiphebus ambiguus. None of the aphid species supported complete development of L. ambiguus despite oviposition by the parasitoid except sipha maydis. Maximum number of aphids were parasitized on the consecutive days. Percent emergence from S. maydis parasitized was decreasing from first towards the last day. Being a very specific strain with restricted host range, a stable sex ratio provides significant advantages in survival under less favorable conditions.
