This study aimed to determine the effects of plant species on biological parameters Tetranychus urticae Koch and time mite infestation physiology in Ocimum basilicum L., Melissa officinalis L. Salvia Mite induced various levels oxidative stress depending duration infestation. Host plants affected T. life table parameters. The low level susceptibility was characteristic S. officinalis, which app...

Bioassays of Rosmarinus officinalis L. essential oil and blends of its major constituents were conducted using host-specific strains of the two-spotted spider mite, Tetranychus urticae Koch, on bean and tomato plants. Two constituents tested individually against a bean host strain and five constituents tested individually against a tomato host strain accounted for most of the toxicity of the na...

two-spotted spider mite, tetranychus urticae koch. is one of the most harmful pest of common bean in most areas of iran, including lorestan province. the appropriate unit and universe sampling of mite population were investigated in common bean fields in borujerd, dorud and azna in 2008. the results showed that samples should be taken from top, middle and bottom of the plant height. in addition...

In group living, species spatial distribution results from responses to environmental heterogeneity and/or mutual interactions between individuals. These mutual interactions can be regulated by genetic and/or epigenetic factors. In this study, we focus on genetic factors and investigate how the spatial distribution of some individuals colonizing a new environment is influenced by inbreeding. Ou...


 Argentina is the second largest peanut (Arachis hypogaea L.) exporter in world. The main pest our country two-spotted spider mite (Tetranychus urticae Koch 1836). To date, there no validated method to quantify this pest. aim of work was develop and validate a logarithmic diagrammatic scale assess damage by peanut. In 2015-16, 200 leaflets were collected from plot infested with Damaged le...

Abstract Background The two-spotted spider mite, Tetranychus urticae (Koch) (Acari: Tetranychidae), is a widely distributed plant-feeding pest that causes significant yield losses in wide range of crops. Newly developed or improved environmentally friendly biocontrol agents serve as an alternative to traditional control tools. Experiment the effects 2 local fungal isolates Beauveria bassiana (B...
