Life history of Neoseiulus agrestis (Karg) (Acari: Phytoseiidae) fed on the storage mite, Thyreophagus sp. (Acari: Acaridae) at different temperatures

The development and life history parameters of Neoseiulus agrestis feeding on the storage mite, Thyreophagus sp., were studied at three different temperatures 20, 25, 30 °C. results show that juvenile oviposition period as well reproductive potential this predatory mite are significantly affected by temperature. times immature expectancy adults ranged from 11.36 to 6.06 days 58.71 38.65 days, respectively, depending average total number eggs laid per female 20 °C (27.21), 25 (46.38), (61.12) differed each other. highest net rate (R<sub>0</sub>) was 51.95 (offspring/individual) °C, although there no significant difference obtained (37.10). Furthermore, intrinsic increase (r<sub>m</sub>) is 0.286 day<sup>-1</sup> Moreover, finite (λ = 1.331 day<sup>-1</sup>) shortest mean generation time (T 13.786 days) doubling (DT 2.418 also determined Our indicate N. successfully completed can survive reproduce all tested.
