Biocontrol Agents and Biopesticides in Mango IPM Next
Background The use of natural enemies of pests to reduce their population at a level below economic losses is termed as biocontrol. Traditionally, this method was employed to control insect pests by parasitoids, predators and insect pathogens. Biological control practices involve three major techniques viz. , introduction, conservation and augmentation. Like for other crop pests, several natural enemies/ bioagents are also being deployed for the management of insect pests in mango. End Previous Next
Biocontrol Agents and Biopesticides: Hoppers Conservation of biocontrol agents like predator, Mallada boninensis, Chrysopa lacciperda, egg parasite, Polynema spp. Gonatocerus sp. , Tetrastichus sp. , and fungus, Verticillium lecanii Spraying of 0. 2% Nimbicidin or Azadirachtin 3000 ppm@2 m/l at initial stage of hopper population.

Biocontrol Agents and Biopesticides in Mango IPM Conservation of biocontrol agents, Beauveria bassiana, predators, Menochilus sexmaculatus, Rodolia fumida and Sumnius renardi, and release of 10 -15 grubs of cocinellid predator, per tree reduces mealy bug population buildup. End Previous Next
The natural enemies viz. , a mite (Rhizoglyphus sp), ants (Camponatus sp. , Monomorium sp. and Oecophylla smaragdina), and fungus, Aspergillus sp. and Beauveria bassiana were recorded and found effective in mango weevil control. End Previous Next
Summary A large number of parasites, predator and pathogens are very active against pests of mango in the fields. These are Rodolia fumida, Suminus renardi, Coccinellids, Beauveria bassiana, Verticillium lacani, Mallada boninensis, Chrysopa spp. , Tertrastichus spp. , Gonatocerus spp. , Podynema spp. , Platygaster sp. , Eupulmus sp. , Systasis dasynearue, Micronimus timidis, Baccha pulchrifrons, etc. Which pay a significant role in population suppression of various insect pests. These natural enemies should be conserved in the field. End Previous
