Abstract

The development time, survivorship and reproduction of the Sarucallis kahawaluokalani (Kirkaldy), Eucallipterus tiliae L., Capitophorus elaeagni del Guercio, Aphis nerii Boyer de Fonscolombe, Cinara cedri Mimeur were studied on the Lagerstroemia indica L., Tilia tomentosa Moench, Elaeagnus angustifolia L., Nerium oleander L. and Cedrus libani Loud. at four constant temperatures (20C, 22.5C, 25C and 27.5C). Total nymphal development time ranged from 7.78 d at 22.5C to 9.81 d at 25C of C.elaeagni, 9.32 d at 25C to 12.5 d at 20C of E. tiliae, 7.08 d at 27,5C to 11.14 d at 20C of S. kahawaluokalani, 15.85 d at 25C to 12.57 d at 20C of A. nerii and 13.00 d at 20C to 10.07 d at 25C of C. cedri. The intrinsic rate of increase (rm) at 22.5C had the highest value for S. kahawaluokalani and C. elaeagni (0.5703) and (0.2945) among all tested constant temperatures. The calculated rm was higher at 25C for E. tiliae (1.4124) and C. cedri (0.2975) and at 20C A. nerii (0.2648). That the optimal temperature for E. tiliae and C.cedri on T. tomentosa and C. libani was 25C, for C. elaeagni and E. tiliae was 22.5C on E. angustifolia and T. tomentosa and for A. nerii was 20C on N. oleander.
