Brève description

Papaya mealy bug Paracoccus marginatus is an invasive pest. The pest was first observed in Coimbatore in Tamil Nadu during 2008 on Papaya crop. Rapid spread of P. marginatus among agricultural and horticultural crops of economic importance was noticed. It was necessary to take up immediate steps to manage it in the places of occurrence to limit the yield and crop losses. Insecticidal treatment against this pest has proved futile in most places and hence, three species of exotic parasitoids effective against the papaya mealy bug were imported from Puerto Rico, and mass multiplied under quarantine at National Bureau of Agriculturally Important Insects (NBAII), Bengaluru. The field releases of these parasitoids gave effective control of the pest in the affected areas. At present there is no report of serious pestilence due to this pest and the pest is below economic threshold level in all the areas where pest is reported in India.
