Effect of two different host plants on biological features of Neoseiulus californicus (McGregor)
International Journal of Acarology 25 (2), 145-150
Abstract: The biological parameters of Neoseiulus californicus (McGregor) preying on Tetranychus urticae Koch of tomato and strawbery were compared. Developmental times were unaffected either by the host plant or by the T. urticae strain. However, sex ratio, mortality and oviposition were more advantageous on strawberry. The worst performance was observed in the second generation on tomato (estimated r_m = 0.118 day^-1); only after numerous generations on this plant the estimated r_m increased to 0.256 day^-1 and was similar to those registered on strawberry.
