During surveys for the collection of Chalcidoidea in different parts of India, several taxa were collected and recorded.  One species of Eulophidae is recorded for the first time from India. Nine species of Pteromalidae, two species of Encyrtidae, four species of Eulophidae, two species of Trichogrammatidae and one species of Torymidae, are new records from Karnataka.  One species of Eulophidae is a new record from Jammu & Kashmir. One species of Chalcididae is a new record from Andhra Pradesh.  The details of the species are discussed here in brief. The specimens of the present study are deposited in the collections of Project Directorate of Biological Control (PDBC), Bangalore and Aligarh Muslim University (AMU), Aligarh.

 

Methods

Specimen collection was done by using a sweep net and aspirator. Along with these, various parasitized pupae, scale infested leaves, parasitized larvae, gall formed leaves, etc. were collected and kept in jars for emergence of parasitoids.  Syrphid puparia, pupae of Exelastis atomosa (Walsingham), Saissetia sp. infested leaves, leaves infested with leaf miners, parasitized larvae of Chilo partellus (Swinhoe), gall infested leaves of Eucalyptus sp., pods of Crotolaria sp. and ootheca of praying mantid were also collected and reared in the laboratory. The collected specimens were then dry mounted and labelled according to the standard procedure provided by Noyes 1982.

The specimens were identified in the Biosystematics and Introduction Division of Project Directorate of Biological control, Bangalore, using Leica S8APO Stereo zoom microscope and with the aid of recent literature as well as the Universal Chalcidoidea database (Noyes 2003).
