Abstract

The developmental time, longevity, fecundity, sex ratio, duration of preoviposition, oviposition and 
postoviposition, number of nymphs and life table parameters of Pseudococcus cryptus (Hempel)
(Hemiptera: Pseudococcidae) were studied on four citrus (Rutaceae) species (Citrus paradisi, C. limon,C. unshiu, C. sinensis ), in an acclimatized room at 25±2C, 60-70% relative humidity and 14:10h (l:d)photoperiod. The results suggest that some of the parameters for P. cryptus populations were affected bythe species of citrus, and that C. limon was the preferred host plant. The population parameters on C. limonwere determined as rm = 0.1526 d-1; R0 0= 65.8 offspring/individual and T = 27.4 days.

The results suggest that some of the parameters for P cryptus populations were affected by the species of citrus, and that C. limon was the preferred host plant. The population parameters on C. limon were determined as r(m) = 0.1526 d(-1); R-0= 65.8 offspring/individual and T-0 = 27.4 days.
