“…Nuclear polyhedrosis viruses recorded in India includes Helicoverpa armigera, Spodoptera littura, Spodoptera exigua, Amsacta moorei, Agrotis ipsilon, Agrotis segetum, Anadividia peponis, Trichoplusia ni, Thysanoplusia orichalcea, Adisura atkinsoni, Plutella xylostella, Corcyra cephalonica, Mythimna separata and Phthorimaea operculella (Erayya et al, 2013). Field evaluation of Lymantria obfuscata multiple nucleopolyhedrovirus for the management of Indian gypsy moth in Jammu and Kashmir, India were reported (Gupta et al, 2016). Optimization with respect to the host insect, insect diet, insect age, virus dosage, incubation, environment, selection of harvesting time and preservation of virus infectivity consist some of the major factors (Gupta et al, 2007), in maximizing the yield of NPV production in individual larvae (Grazywacz et al, 1998).The combined use of microbial formulations has attained greater option among agricultural community as a successful tool in integrated pest management strategies (Purwar and Sachan, 2006).…”
