Endosymbiotic Bacteria Associated with the Mealy Bug, Rhizoecus amorphophalli (Hemiptera: Pseudococcidae)

Autor: C. A. Jayaprakas, Sasidharan Nishanth Kumar, L Ragesh, R.S. Sreerag

Publikováno v: International Scholarly Research Notices

The mealy bug, Rhizoecus amorphophalli, is a menace to the aroid farmers due to the intensive infestation on stored tubers. Spraying of pesticides was able to control this pest but it always left a chance for fungal growth. Bacterial endosymbionts as
