Functional and numerical responses of the predatory mite, Neoseiulus longispinosus (Evans) (Acari: Phytoseiidae) to the red spider mite, Oligonychus coffeae Nietner (Acari: Tetranychidae), infesting tea were determined in a laboratory on leaf discs. Prey consumption increased with increases in temperature and prey density. Handling time decreased and successful attack rate increased with increa...

Identification of spider mites based on morphological characteristics is difficult because morphological differences between species may be subtle and in some groups, including the Tetranychus Dufour species, detectable only in adult males, which usually correspond to a small proportion of a population. The utility of an alternative method, phosphoglucomutase (PGM) zymogram, is demonstrated in ...

C1A plant cysteine proteases are synthesized as pre-pro-enzymes that need to be processed to become active by the pro-peptide claves off from its cognate enzyme. These pro-sequences play multifunctional roles including the capacity to specifically inhibit their own as well as other C1A protease activities from diverse origin. In this study, it is analysed the potential role of C1A pro-regions f...

A study was conducted during 2009-10 to assess the toxicity of chloroform extracts of Pogostemon parviflorus (Benth.) and Polygonum hydropiper (L) against red spider mite (Oigonychus coffeae, Neitner) under laboratory condition using leaf detached method. Both the plant extracts possesed the acaricidal properties on developmental stages of red spider mite. The treatment with both plant extracts...

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

salinity stress is one of the most important abiotic factors that restrict the growth and yield of many plants. salinity can increasingly influence the host susceptibility, occurrence and development of plant diseases due to its negative effects on the host plants. mycorrhizal fungi are able to increase the tolerance of some plants to salinity. in this study, the biological effects of glomus mo...

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 is one of the polyphagous pests of crops worldwide. due to undesirable effects of synthetic pesticides such as expression of resistance in mites, this research was conducted to achieve alternative safe compounds to environment. therefore, ovicidal activity of essential oils of eucalyptus salmonophloia f. muell and eucalyptus kingsmillii maide...

The two-spotted spider mite Tetranychus urticae Koch is one of the economically most important pests in a wide range of outdoor and protected crops worldwide. Its control has been and still is largely based on the use of insecticides and acaricides. However, due to its short life cycle, abundant progeny and arrhenotokous reproduction, it is able to develop resistance to these compounds very rap...
