Cotesia plutellae (Kurdjumov) is an indigenous, larval endoparasitoid that attacks mid instar larvae of the diamond back moth (DBM). Although the parasitoid is distributed widely, not all local populations appear to be equally effective in controlling the DBM. Bacterial endosymbionts may play regulatory role in determining their efficiency. Field collected C. plutellae populations from cauliflower fields were assessed for the prevalence of the bacterial endosymbionts. Bacterial endosymbionts in the genus Wolbachia were detected in the populations obtained from Hoskote (Karnataka) and Thirupathi (Andhra Pradesh). PCR amplification using specific primers for Wolbachia revealed 528 and 518 bp for the populations, respectively. Sequencing of the Wolbachia surface protein, wsp, revealed Wolbachia infection to be related to Wolbachia endosymbiont of Cotesia glomerata outer surface protein, wsp gene (Genbank Accession No. AB094202) with maximum identity of 99% with BLAST search of NCBI. The sequence was submitted to the GenBank with the Accession No. JF421566. The detection of Wolbachia in the parasitoid signifying its role in biological manipulations of the parasitoid for enhanced efficiency is discussed.Keywords

The cytochrome oxidase gene (COI) was employed to assess the genetic variation in different populations of Cotesia flavipes. Partial sequences of the COI gene for the populations from Bangalore, Hyderabad, New Delhi and Shimla were analyzed to assess the homology and the usefulness of this genetic region for phylogenetic studies. PCR using COI-F and COI-R primers amplified a product of approximately 550 bp which was similar for all the four populations. Populations were by and large similar in the COI gene sequenced and there was no variation with our sequences and those of sequences worldwide. The multiple alignments were performed for four populations which revealed similarity of the partial COI gene sequences. Comparative analysis of partial sequences of COI gene produced a phylogenetic tree. Phylogenetic analysis revealed that all our populations were in a single clade with high boot strap value, suggesting highest similarity.Keywords

The Chrysoperla species (carnea-group) widely used in India in augmentative biological control programmes was found to be Chrysoperla zastrowi arabica Henry et al. The acoustic profile of the mating song of this species was analyzed and found to match that of C. zastrowi arabica, the song species characterized earlier as 'Cc5 generator'. The correct taxonomic name for this species remains to be determined as it is morphologically identical to C. sillemi (Esben-Petersen), a species already known from India. Molecular characterization of the species was also done and the DNA sequence of the ITS-2 region was deposited in GenBank (Accession No. DQ 825504, as that of C. sillemi). The implications of this finding are discussed.Keywords
