temperature effects on development and life table parameters of tetranychus urticae (acari: tetranychidae)
development, reproduction and life table parameters of tetranychus urticae koch were determined on leaves of peach (g. h. hale cultivar) at different temperatures, ranging from 13 to 33°c under laboratory conditions. no development was observed at 13°c. egg-to-adult developmental time decreased gradually from 17 to 27°c and increased at higher temperatures (27 to 33°c). an average of 136.43 deg...

J. Agric. Entomol. l(}(3):197-203 (July 1993) ABSTRACT Based on data from apple trees without the presence of any predatory mites, the effect of the pyrethroid lambdacyhalothrin on population density of the twospotted spider mite, Tetranychus urticae Koch, is reported. Results show that significantly (P < 0.05) higher numbers of T. urticae were found in pyrethroid·treatcd trees relative to the ...
متن کاملReproductive parameters of Phytoseiulus macropilis (Banks) fed with Tetranychus urticae Koch (Acari: Phytoseiidae, Tetranychidae) in laboratory.
Predatory mites that belong to the Phytoseiidae family are one of the main natural enemies of phytophagous mites, thus allowing for their use as a biological control. Phytoseiulus macropilis (Banks, 1904) (Acari: Phytoseiidae) is among the main species of predatory mites used for this purpose. Tetranychus urticae Koch, 1836 (Acari: Tetranychidae) is considered to be one of the most important sp...
متن کاملLife Table and Predation Capacity of Phytoseiulus persimilis Athias-Henriot (Acari: Phytoseiidae) Feeding on Tetranychus urticae Koch (Acari: Tetranychidae) on Rose
The life history and predation rate were determined for all stages of female and male of Phytoseiulus persimilis Athias-Henriot fed on the eggs of Tetranychus urticae Koch ˗ as the preferred prey-stage ˗ on rose (cv ‘blarodje’) leaf discs under laboratory conditions at 25±1°C, 75±5% RH, and 16 L: 8 D hour photoperiod. According to the age-stage, two-sex life table model, the intrinsic rate of i...
