Article
Monthly abundance of Tetranychus urticae along with its predators, Phytoseiulus persimilis, Scolothrips longicornis and Stethorus gilvifrons were studied on Cucumis sativus and Solanum melongena at different sites. This study was conducted for one year, extending from February 2014 to January 2015 at two namely: Sarabium and Wasfia regions, in Isma...
Article
This study investigates the acaricidal, ovicidal, and repellent effects of the Tagetes patula Linn. (Asteraceae) leaf extract against both the adult female and egg stages of Tetranychus urticae Koch (Trombidiformes: Tetranychidae) under laboratory conditions. The Tagetes patula ethanolic leaf extract [Tp EtOH70% ] was screened for adulticide and ov...
Article
The aim of this study was to investigate the effect of site and temperature on the percentage of leaves infested by the two-spotted spider mite, Tetranychus urticae Koch, and on the density of the spider mite and its predators on three crop species of economic importance. From February 2014 to January 2015, a survey was conducted on cucumber (Cucum...
Article
Field evaluation for the acaricidal activity of jatropha (Jatropha curcas L.) and castor bean oils (Ricinus communis L.) against the nymphs and adults stages of the two-spotted spider mite, Tetranychus urticae on Alcea rosea L. were studied. The field trial was conducted out in May 2016 on A. rosea in the experimental farm of Faculty of Agriculture...

Article
The objective of this research was to study the abundance and prevalence of Brevipalpus phoenicis and its predators on Gerbera jamesonii Bolus and its relation with different weather variables during a one-year study 2015 at Ismailia Governorate, Egypt. The abundance of B. phoenicis life stages was monitored monthly. The effects of mite's infestati...
Article
The acaricidal activity of some essential and fixed oils against the two-spotted spider mite, Tetranychus urticae Koch were evaluated at 15 °C, 27 °C and 35 °C under laboratory conditions. The essential oils namely, rosemary (0.125%), garlic (0.5%), jojoba (0.25%) and the fixed vegetable oil (soyabean and sunflower oil (0.125%)) were tested in this...

Article
A comparison was made for studying the effect of some Essential oils: Rosemary, Garlic, Jojoba and Fixed/Vegetable oils on the important mite pest, Tetranychus urticae. The sublethal concentrations of Rosemary oil (0.125%), Garlic oil (0.5%), Jojoba oil (0.25%) and Vegetable oil (0.125%) were used. Biological tests were carried out for a susceptibl...
Article
Certain effects of different spectral light colors were studied on some biological attributes of the two-spotted spider mite, Tetranychus urticae. Rearing of animals was carried out under conditions of 27±0.5°C; 60% R.H. and 16 L/8 D photoperiod on Sweet Potato leaves. Thus, 5 artificial light colors were applied under controlled laboratory conditi...
Article
n s the present study, the seasonal abundance of the two-spotted pider mite (TSSM), Tetranychus urticae Koch, and the relation with the naturally occurring predatory arthropods were investigated to explain variations in population numbers of the mite infecting the Castor bean crops. During a one-year study on Castor bean trees, results showed that,...

Spinosad is a bioinsecticide with a high degree of selective toxicity towards insects of different orders, but its toxicity towards the two-spotted spider mite (TSSM), Tetranychus urticae Koch (Acari: Tetranychidae) is under debate. In this study, we compared the acaricidal properties of spinosad with the commercial bioacaricide abamectin on the li...
