Abstract

The sugar beet moth, Scrobipalpa ocellatella Boyd. (Lep.: Gelechidae( is the specific pest of beet. The aim of the present study was to identify the Parasitoids of the moth. In this regard, sampling was conducted in Fields of Khorasan-e-Razavi Province during 2010 from early July until October. Larvae and pupa were collected along with tubers of sugar beet and then were reared under controlled conditions, 25±2°C, 65±5% Rh and 14L:10D until the emergence of parasitoid adults. Tubers were investigated daily and emerged parasitoids were collected. These parasitoids were put in alcohol 75°. In this study two species of larval parasitoids were collected and identified including Bracon intercessor Nees and Microchelonus subcontractus Abdinbekova and both of them belong to family Braconidae.  B.  intercessor is larval parasitoid and M. subcontractus is larva-pupal parasitoid. Paratype samples of the collected parasitoids are maintained in Laboratory of Entomology, Shahed University.
