Biological control of diamondback moth Plutella xylostella (L.), an Indian scenario with reference to past and future strategies
Diamondback moth (DBM), Plutella xylostella (L.)(Lepidoptera: Yponomeutidae) is a major pest of cabbage and cauliflower in India, Several natural enemies such as parasitoids, predators and insect pathogens have been reported from different parts of the country. Only very few parasitoids have been exploited for the control of DBM either as a sole method of biological control or incorporated as one of the components in Integrated Pest Management strategies. Trichogrammatoidea bactrae Nagaraja and Cotesia plutellae Kurdj, were studied exhaustively and used against DBM. No effort has been made either to conserve the predators or to exploit for the control of DBM. Entomopathogens will certainly play a vital role in the suppression of DBM when used as insecticidal sprays. Bacillus thuringiensis (Bt) has been used for the control of DBM. Other agents have not been exploited. A future strategy in biological control of DBM in India suggested here is the integration of inundative releases of the egg parasitoid, T. bactrae, conservation of C. plutellae and spraying of Paecilomyces farinosus (Holmskiold) Brown and Smith or granulosis virus or Greater wax moth nuclear ployhredrosis virus.
