Twelve field experiments and one laboratory experiment were conducted to determine the effects of furrow applied aldicarb and seed treatments of thiamethoxam, imidacloprid, Avicta (thiamethoxam + abamectin), Aeris (imidacloprid + thiodicarb), and acephate on twospotted spider mite, Tetranychus urticae Koch, on cotton, Cossypium hirsutum L. For the field experiments, data were pooled across all ...
Black bean genotypes have high resistance to the important pests and diseases of common bean. To evaluate the effectiveness of four genes in the direct (plant negatively effects on biology and reproduction of herbivore by its physical and biochemical barriers) and or indirect)by attracting natural enemies of herbivores(in black beans against two spotted spider mite, expression levels of these g...
A comparative study was made between the acaricidal activities of some essential oils: rosemary (Rosmarinus officinalis L.), lavandula (Lavandula angustifolia Mill.), thyme (Thymus vulgaris L.) and ziziphora (Ziziphora clinopodioides Lam.) on the important mite pest, Tetranychus cinnabarinus Boisduval, the carmine spider mite, oncut roses during 2010-2012. The sublethal concentrations of ziziph...
the two-spotted spider mite, tetranychus urticae koch (acari: tetranychidae), is an economically important pest of ornamental plant in iran. the population abundance and spatial distribution were studied on five rosa cultivars including maroussia, wendela, elderado, wenedetta, and hot lady during two growing seasons of 2011 and 2012 in greenhouse. the k parameter, index of dispersion, lloyd’s m...
Most molecular-genetic studies of plant defense responses to arthropod herbivores have focused on insects. However, plant-feeding mites are also pests of diverse plants, and mites induce different patterns of damage to plant tissues than do well-studied insects (e.g. lepidopteran larvae or aphids). The two-spotted spider mite (Tetranychus urticae) is among the most significant mite pests in agr...
BACKGROUND Studies in patients with allergic rhinitis living in the Free State have showed grass pollens to be the predominant allergens, with house-dust mite sensitisation being less prevalent than in the coastal areas and a low rate of sensitisation to the storage mite Lepidoglyphus destructor. No studies have been conducted on sensitisation to the other storage mites, spider mites or cockroa...
Integrated pest management (IPM) tactics may effectively control focal pests, but it is also important to test the compatibility of different tactics, and consider non-target organisms. We investigated the effects of a neonicotinoid seed treatment and Rag resistance genes used for soybean aphid (Aphis glycines Matsumura) control on reproduction of a non-target herbivore (twospotted spider mite,...
Acaricide is a pesticide designed to control harmful species of mites (Acari)1. In crop protection practices, acaricides are used against phytophagous mites, pests causing economic injuries to agricultural crops and ornamental plants. Until mid-twentieth century, in agroecosystems of low-level productivity, phytophagous mite populations usually stayed below economic injury levels, due to natura...
Adult female twospotted spider mites, Tetranychus urticae Koch, reared on lima bean plants were moved to cucumber, maize, or new lima bean plants (the latter being a control) and evaluated after 24 h or 7 d for changes in susceptibility to three pesticides and in levels of related detoxification enzymes. The largest and most consistent changes were observed in mites feeding on cucumber. Suscept...
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 ...
