Mani, M., & Krishnamoorthy, A. 1998 Biological control studies on the mango green shield scale Chloropulvinaria polygonata (Ckll.) (Homoptera, Coccidae) in India.. Entomon 23(2): 105-110.

Notes: The green shield scale Chloropulvinaria polygonata (Ckll.) has become a serious pest of mango in the Indian subcontinent in spite of the application of insecticides. C. polygonata was attacked by three parasitoids namely Coccophagus bivittatits, C. nigricorpus sp. nr. Metaphycus helvolus, and three predators viz. Cryptolaemus montrouzieri, Mallada astur and Spalgis epius in mango orchards around Bangalore. The coccinelid C. montrouzieri is a new record on C. polygonata, though it has been recorded on other species of Chloropulvinaria. A study conducted on the predatory potential of C. montrouzieri revealed that the predator consumed about 2400 eggs of C. polygonata in its larval developmental period of +15.40 days. C. montrouzieri was found to be very effective in suppressing the scale population in two mango orchards near Bangalore.
