Chemical Spray and Mango Hopper
Use of chemical insecticides and pesticieds will reduce flower pollination and fruit setting capacity. Without pollinators the yield of mango is very much declined when comparing with natuural pollinator honey bees.

Biological Control for hopper and other pests in mango Biological control is regarded as effective, long-term solution to the mealy bug infestation because parasites and predators are self-perpetuating, persists even when the mealy bug is at low population densities, and they continue to attack the mealy bugs, keeping populations below economic injury levels. The coccinellied beetles such as Cheilomenes sexmaculata, Rodolia fumida, Scymnus coccivora, Aulis vestita, Coccinella septempunctata and Nephus regularis are important predators of mealy bug nymphs. Biological control by release of natural enemies has proved very successful. Among the biological control agents introduction of Cryptolaemus montrouzieri (Australian Ladybird), Anagyrus pseudococci, Leptomastix dactylopi, Hypoaspis sp., Verticillium lecanii and Beauveria bassiana are effective in managing the infestation. Hypoaspis is a small mite feeds on crawlers. Soil application of the spores of the fungus, B. bassiana will ensure further reduction of the pest population
