The spider mite Tetranychus evansi is an emerging pest of solanaceous crops worldwide. Like many other emerging pests, its small size, confusing taxonomy, complex history of associations with humans, and propensity to start new populations from small inocula, make the study of its invasion biology difficult. Here, we use recent developments in Approximate Bayesian Computation (ABC) and variatio...

reproductive performance and life expectancy of the two-spotted spider mite (tssm), tetranychus urticae koch were determined on seven eggplant cultivars (isfahan, dezful, shend-abad, neishabour, bandar-abbas, jahrom and borazjan) at 25 ± 1°c, 60 ± 5% r.h. and a photoperiod of 16:8 (l:d) hours. the results revealed that the tssm gross hatch rate varied from 59% on bandar-abbas to 83% on dezful. ...

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 ...

food choice in omnivorous animals is influenced by the balance of nutritional needs, food availability, and quality of a particular food items. here, we study whether omnivorous onion thrips, thrips tabaci lindeman, feed on the eggs of its competitor tetranychus urticae koch (acari: tetranychidae) when an alternative supplemental source is, or is not, available. thrips were either fed a cucumbe...

The spider mite, Tetranychus truncatus, is a polyphagous agricultural pest harboring various endosymbionts, such as Wolbachia and Spiroplasma. How they interact with each other in the same host not clear. temperature impacts their interaction endosymbionts remains largely unknown. Furthermore, little known about bacterial communities of truncatus molecular mechanism underlying regulation genes....
