E-resource on mass production protocols for agriculturally important insects contains mass production protocols developed in India for important host insects, parasitoids and predators based on information generated through a thorough literature survey. This database is developed by use of simple HTML tags. It is user friendly and retrieval of information is easy. It contains mass production protocols of around 42 host insects including Spodoptera litura (Lepidoptera: Noctuidae), Helicoverpa armigera (Lepidoptera: Noctuidae) and Corcyra cephalonica (Lepidoptera: Pyralidae), 52 parasitoids including species from Trichogrammatidae, Braconidae, Scelionidae, Ichneumonidae, and 21 predators including species from Chrysopidae, Anthocoridae, Syrphidae and Coccinellidae. The database contains abstracts which have been published in different scientific journals. It also contains some video clips, which help to easily understand the methodologies involved in mass production. This e-resource can be used as a demonstration tool for extension workers. This IT-based Web portal can be a handy-tool for students, researchers, entrepreneurs, extension workers and farmers to absorb the information related with mass production protocols for macrobials.
