Abstract

In a field survey, Aceria fictis, Tetranychtis urticae and the predator, Phytoseius finitimtis, were registered on fig trees from mid of March 2013 to mid of January 2014. A. fiicus population reached its peak at mid September with mean number of 29.05 individuals/leaf. T. iirticne at the end of August with mean number of 10.9 individuals/leaf, whereas the predator,
P. finitim us reached at mid September. For control, the highest reduction percentages in eriophyid mite population occurred when P. finitimtis was released by 1 predator/3 Eriophyid mite, resulting in reduction of 90.21 %. The tested pesticides: Acaristop, Dumper and High point, recorded reduction percentages 88.14, 86.84, and 85.06 % in eriophyid mite population, respectively, while red pepper plant extract gave 82.39 %. Numbers of T. urticae decreased after all levels of release, where the highest decrease was at the level of 1 predator: 3 preys (0.03, 0.8 individual/ leaf) after 2 and 4 weeks, respectively, when compared with check. The study recommend the efficiency of the predatory mite, P. finitimu8 at release levels of 1: 3 and 1: 5, in addition to red pepper plant extract 10 %.
