although host plant resistance is the healthiest, most reliable and cheapest way of pest control, to achieve a successful integrated pest management, pest-resistant plant varieties should be compatibity with the biological control agents. throughout the present study, the performance of the predatory mite, phytoseiulus persimilis، on four common bean cultivars (naz, khomein, akhtar and g11867) ...
medicinal plants were used from past to present. different small arthropods such as acari were found on these plants. therefore a study on the acari fauna associated with some medicinal plants (family: asteraceae) in hamedan region was carried out during 2008–2009. in this survey, 23 species belonging 18 genera from 15 different families of the subclass acari were collected and identified. two ...
Plants under herbivore attack are able to initiate indirect defense by synthesizing and releasing complex blends of volatiles that attract natural enemies of the herbivore. However, little is known about how plants respond to infestation by multiple herbivores, particularly if these belong to different feeding guilds. Here, we report the interference by a phloem-feeding insect, the whitefly Bem...
We report the first occurrence in Africa, Burkina Faso, of an exotic spider mite, Tetranychus truncatus, including new host records. Due to morphological variation specimens we observed, used molecular and approaches obtain a reliable identification this alien species. Sampling events also disclosed two mite records for Eutetranychus orientalis urticae several plant
BACKGROUND Prenatal or embryonic learning, behavioral change following experience made prior to birth, may have significant consequences for postnatal foraging behavior in a wide variety of animals, including mammals, birds, fish, amphibians, and molluscs. However, prenatal learning has not been previously shown in arthropods such as insects, spiders and mites. METHODOLOGY/PRINCIPAL FINDINGS ...
BACKGROUND: Chemical control of spider mites and thrips in everbearer strawberry is difficult as few efficient chemicals are available and residues represent a risk. In the north the success of biocontrol of mites and thrips in open fields compared with tunnels needs to be evaluated. OBJECTIVES: To investigate the need for control of spider mites and thrips and evaluate the effectiveness of bio...
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...

RNA interference (RNAi) can be used for the protection against agricultural pests through the silencing of genes required for pest fitness. To assess the potential of RNAi approaches in the two-spotted spider mite, Tetranychus urticae, we compared 5 methods for the delivery of double-stranded RNA (dsRNA). These methods include mite feeding on either (i) leaves floating on a dsRNA solution, (ii)...
