Biodiversity of braconid pest biological control agents from southern Maharashtra.

Abstract

Thirty-seven species of braconid (Braconidae) parasitoids were identified in southern Maharashtra, India, during a study conducted in 1994-2003. Cotesia, Apanteles, Dolichogenidea, Microplitis, Bracon, Chilenus, Glyptapanteles, Meteorus and Rhigoplitis species were the most common in this region. Cotesia flavipes, Cotesia chilonis and Cotesia sesamiae parasitized 22, 5 and 7% of the larvae of Chilo partellus, respectively. Cotesia ruficrus attacked 8% of the larvae of Helicoverpa armigera. Cotesia glomerata parasitized 4% of the larvae of Pieris brassicae, whereas Cotesia orientalis and Cotesia diurnii parasitized 30 and 11% of Exelastis atomosa larvae, respectively. Meteorus dichomeridis and Meteorus spilosomae parasitized the larvae of Spilosoma obliqua [Spilarctia obliqua] (34 and 12%). Parasitism by Apanteles spp. ranged from 5 to 34%. Bracon brevicornis parasitized the larvae of Earias fabia [E. vittella] (18%) and Earias insulana (7.5%). D. mythimna was an effective parasitoid of Mythimna separata (36%). G. malshri parasitized 13% of Plutella xylostella larvae.
