Mealybugs are found to infest pigeon pea (redgram) Cajanus cajan in India, Trinidad, Africa and Ghana. Coccidohystrix insolita found causing damage to pigeon pea in Gujarat and Tamil Nadu, in India. The affected leaflets turn yellow and drop off. The plant becomes stunted initially.

Severe incidence causes wilting and drying of plants. Maconellicoccus hirstutus has been reported to cause 15 % plant infestation on pigeonpea in Gujarat, India, Paracoccus marginatus was reported to cause 25 % damage to pigeon pea in Tamil Nadu. In Haryana, nymphs and adults of the mealybug Ferrisia virgata were found mainly on the inflorescences causing withering and dropping of flowers. In Bangalore, India, Dysmicoccus brevipes was found infesting the root nodules of red gram in southern India. More than 95 % reduction in field population of C. insolita was observed with the applications of lambda cyhalothrin, dichlorvos and profenophos in Tamil Nadu. There are many parasitic wasps and various predatory insects that feed on mealybugs. Cryptolaemus montrouzieri can be used to control the mealybugs in general. Host specific parasitoid Acerophagus papayae Noyes and Schauff for P.marginatus can be used to control the Pa. marginatus.
