The Efficiency of Parasitoid Cotesia sesamaie (Hymenoptera Braconidae) to Control the Larvae of Tarucus rosacea In Al-Diwaniyah City

Abstract

The present search include the recognize the efficiency of pasitoid C. sesamiae on control the larvae of Tarucus rosacea in farm to period from May/2013 until April/2014, this parasitoid discern that infected all the larval stages of the host but in disparate issues. The highest number of parasitoid on the 3^rd larval instar (73), while the lowest number on the 1^st larval instar (8). The highest parasitism percent will be at November 2013 reach to (63.15%) on 3^rd larval instar, while the lowest average of parasitism in the same month at the 1^st larval instar (14.28%). The females of parasitoid appear its ability to recognize between the infected and non infected larvae of the host in farm from laying one egg only per larva.
