Abstract
A preliminary study was carried out to control the two-spotted spider mite, Tetranychus urticee Koch on cucumber in a net greenhouse and in open field by releasing the predatory mite, Phytoselutus macropilis (Banks). The T. urticae reduction in the greenhouse reached about 90 % after 24 and 28 days from the predator release at the rate of 4 and 2 individuals/pot, respectively. Maximum reduction of the pest in open field was 85 and 90 % after 4 weeks from the predator release at the rate of 5 and 10 individuals/pot, respectively. The previous study indicated the possibility to control the two-spotted spider mite, t union on cucumber by using P. macropilis as a biocontrol agent.
