Ibrahim Y.B., . and Seo W.M., . Behaviour of the predatory mite Amblyseius longispinosus (Evans) on twospotted spider mite as prey (Acarina: Phytoseiidae; Tetranychidae). pp. 67-72. ISSN 0126-8643
Abstract
Experiments were conducted to determine the development reproduction life table and feeding behaviour of the predatory mite Amblyseius longispinosus (Evans) when subsisted either on the normal twospotted spider mite (TSSM) or the red form of TSSM (RSM). The predator has a typical life cycle and the duration did not differ significantly when fed either TSSM or RSM. Both prey species were acceptable hosts for the development of the predator. It was also found that: the males reached adulthood 2-5 h sooner than females; the percentages reaching maturity were rather similar; and 71 percent and 66 percent of those fed with TSSM and RSM respectively became females. Life table parameters revealed that the predator's development and reproduction were slightly better when subsisted on RSM than on TSSM. This was as expected since in nature the predators preferred firstly larvae nymphs eggs and lastly the adults (P0.005). Adult preys were observed to be difficult to pursue by A. longispinosus because of their larger size and ability to move away when attacked. There was no difference in the consumption between the two prey species for all developmental stages
