Effect of Verticillium lecanii on biological characteristics and life table of Serangium japonicum (Coleoptera: Coccinellidae), a predator of whiteflies under laboratory conditions
Insect Science 15 (4), 327-333
Abstract: Effects of entomopathogenic fungus Verticillium lecanii on biological characteristics and life table of Serangium japonicum, a predator of whiteflies against five different conidial concentrations (1×10⁴, 1×10⁵, 1×10⁶, 1×10⁷, and 1×10⁸ conidia/mL) were studied under laboratory conditions. The developmental periods for all immature stages (from eggs, 1st, 2nd, 3rd, 4th instar nymph and pupae up to emergence) among the treatments were significantly different when compared to that of control, and the longest development period was observed as treated with 1×10⁸ spore/mL. However, no significant difference on the percent survival of all immature stages was observed among the treatments and control. Also, there were no significantly different effects of V. lecanii on mean generation time, intrinsic rate, the finite rate of increase and longevity of S. japonicum among the treatments and control.
