Occurrence of Papaya Mealybug, Paracoccus marginatus Williams and Granara De Willink (Hemiptera:Pseudococcidae), on Cotton


  • Central Institute for Cotton Research, Department of Entomology, Regional Station, Coimbatore, Tamil Nadu, 641003, India


The papaya mealy bug, Paracoccus marginatus Williams and Granara de Willink, was recorded in severe form on cotton in Coimbatore in 2008-09. Infestation leads to drying of the sympodial branches and both Bt and non-Bt cotton hybrids have been observed to be infested. Spalgis epius (Westwood) (Lepidoptera: Lycaenidae) was recorded as a predator on P. marginatus infesting cotton and other hosts like papaya, silk cotton, subabul, Ixora sp., Crotons, Gliricidia sp. and Hibiscus sp. The larvae of S. epius were found to be voraciously feeding on the egg masses, nymphs and adults of the mealybugs.
