Biology of Phytoselulus persimilis (Acari: Phytoseiidae) on different temperatures

Abstract

The Phytoseiid mite Phytoseiulus Persimilis (Athias-Henriot) (Acari: Phytoseiidae) was reared individually on Tetranychus urticae Koch (Acari: Tetranychidae) and its developmental period, the longevity of female, males and also female fecundity was recorded under various temperatures 20 and 25 Cº about 70% RH. The longevity of females and also female fecundity were recorded under alternating temperatures of 10-20 Cº and 15 -20 Cº about 70% RH. The female developed faster when they were reared at a higher temperature of 25 Cº and they showed higher longevity and fecundity at 25 C֠ than at 2 Cº also, the fecundity and longevity were higher at 15 -20 Cº than at 10-20 Cº.
