摘要

The invasive mealybug Phenacoccus madeirensis Green was recorded from cultivated cotton crop near Bandipur National park, Karnataka. Although the mealybug was recorded previously on Cestrum nocturnum during the current year, severe infestation was recorded for the first time on cotton crop. The parasitoid fauna recorded from P. madeirensis included predominantly Anagyrus quadrii, Anagyrus loecki and Alotropa spp.
