funded by the Indian Council of Agricultural Research, New Delhi. Dr. P. M Sureshan, Scientist, Gopalpur-On-
sea, Orissa is gratefully acknowledged for providing literature and Dr. M. Hayat, AMU, for identifying some encyrtids.
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 labelledaccording 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 LeicaS8APO Stereo zoom microscope and with the aid of recent literature as well as
the Universal Chalcidoidea database (Noyes 2003).
