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...

Abstract Zoophytophagous arthropods can elicit plant defense responses affecting potential prey beyond predation. Phytophagy prevails as the main trigger for these responses, in case of Euseius stipulatus (Athias-Henriot) (Mesostigmata: Phytoseiidae), a predator occurring citrus. Because other triggers cannot be excluded, our aim was to examine whether phytoseiids co-occurring with E. but not e...

Abstract Background Selection of suitable predators for the control spider mite, Panonychus citri is always a challenge due to lack their reliable predicted efficacy. In this laboratory study, biological potential Neoseiulus californicus , N. cucumeris and Scapulaseius newsami, against P. using “Relative Control Potential” (RCP) metric compare efficacies was evaluated. The functional response t...
