Spider mites of the genus Tetranychus are difficult to identify due to their limited diagnostic characters. Many of them are morphologically similar and males are needed for species-level identification. Tetranychus urticae is a common interception and non-regulated pest at New Zealand's borders, however, most of the intercepted specimens are females and the identification was left at Tetranych...

INTRODUCTION Several arthropod pests infest strawberry crop in California and cause a significant yield loss according to Zalom, Bolda, Dara, and Joseph [1]. Strawberry is an important commercial crop and the annual report from California Department of Pesticide Regulations [2] indicates that large quantities of acaricides, fungicides, herbicides, and insecticides are applied to manage a variet...

The prey preference of polyphagous predators plays an important role in suppressing different species of pest insects. In this study the prey preference of the predatory mite, Amblyseius swirskii (Athias-Henriot) (Acari: Phytoseiidae) was examined between nymphs of the twospotted spider mite, Tetranychus urticae Koch (Acari: Tetranychidae) and first instar larvae of the western flower thrips, F...

Jasmine Jasminum sambac L. is an important ornamental crop that fetches recurrent income to farmers. The present study was carried out in three locations Sevandhanagar, Navalurkuttappattu and Horticulture farm, TNAU, Tiruchirappalli, Tamil Nadu, India from August 2019 September 2020. seasonal incidence of major insect pests such as Hendecasis duplifascialis Hampson, Nausinoe geometralis Guenee,...

Two spotted spider mite (TSSM), Tetranychus urticae Koch, is an important pests on bean in Markazi Province (center of Iran). To evaluate the bioacaricidal activity of extracts of three essential oils of thyme (Thymus vulgaris), lavender (Lavandula officinalis)  and eucalyptus (Eucalyptus camaldulensis) against T. urticae on cherry bean (Vigna unguiculta subsp. sinensis), five different concent...

Changes in plants following insect attack are referred to as induced responses. These responses are widely viewed as a form of defence against further insect attack. In the current study we explore whether it is possible to make generalizations about induced plant responses given the unpredictability and variability observed in insect-plant interactions. Experiments were conducted to test for c...

Phytoseiulus persimilis Athias-Henriot is an important biocontrol agent for controlling spider mites (Tetranychus spp). Rearing P. relatively expensive due to the need raise (e.g. Tetranychus urticae Koch), as prey, on live plants. Frozen eggs of T. can be easily stored and used a potential feed laboratory rearing persimilis. This study investigated performance frozen compared with fresh food U...
