Five phytoseiid mite species: Phytoseiulus persimilis Athias-Henriot, Neoseiulus californicus（McGregor）, womersleyi（Schicha）, Amblyseius eharai Amitai and Swirski, Euseius sojaensis（Ehara）（Acari: Phytoseiidae）were collected from commercial Japanese pear orchards in Shizuoka Prefecture. To evaluate the suppressive effect of generalist species on spider Tetranychus kanzawai Kishida（Acari: Tetrany...

This study aimed to determine the predatory performance of Phytoseiulus persimilis Athias-Henriot (Acari: Phytoseiidae) against Tetranychus urticae Koch Tetranychidae) on six different cotton varieties (Gloria, Lima, Carla, DP-396, Edessa, ST-468) with leaf characteristics. The eggs and protonymph stages prey densities (5, 10, 20, 40, 80 160) were separately offered a single female predator its...

The tomato red spider mite, Tetranychus evansi Baker and Pritchard, has emerged as a destructive invasive pest of solanaceous crops worldwide. It was first recorded in Syria 2011, Latakia governorate, the coastal region. Successful management T. given region benefits from information about its distribution, host plants, associated natural enemies. Therefore, we investigated, 2019 2020, status o...

We investigated the role of polyamines (PAs) in lima bean (Phaseolus lunatus) leaves on the production of herbivorous mite (Tetranychus urticae)-induced plant volatiles that attract carnivorous natural enemies of the herbivores. To do this, we focused on the effects of the exogenous PAs [cadaverine, putrescine, spermidine and spermine (Spm)] on the production of volatiles, H(2)O(2) and jasmonic...
