Mishra, D., Mukhopadhyay, A.K., & Pramanik, A. 2004 Biology of the mealybug Phenacoccus bengalensis Pramanik and Ghose, 1999 (Homoptera: Pseudococcidae).. Uttar Pradesh Journal of Zoology 24(2): 155-159.

Notes: The biology of the mealybug, P. bengalensis, was studied on sprouted potato tubers in the laboratory at 28.8-32 deg C and 88-96% RH. The nymphs completed their ecdysis at the age of 20.01 plus or minus 2.32 days and all of them became adult females. The females started oviposition at the age of 31-42 days. The preoviposition and oviposition period, fecundity and incubation period of eggs were 14.20 plus or minus 1.93 days, 9.08 plus or minus 1.89 days, 67.42 plus or minus 8.62 eggs per female and 4.57 plus or minus 1.55 days, respectively. The starvation of females had little effect by reducing 22.28% fecundity and 18.50% oviposition period. The longevity of adult female ranged from 47 to 55 (50 plus or minus 2.94) days and the species reproduced parthenogenetically.
