Tetranychus urticae is considered one of the main plagues in the world. Its occurrence in Pernambuco was registered for the first time in 1985 and it has caused considerable damage to the farmers, attacking different cultures of agricultural interest. The essential oils from different parts of Vitex agnus-castus harvested in the Atlantic forest in the state of Pernambuco, Brazil, were obtained ...

Seasonal abundance of spider mites and their predators on red raspberry was studied in 1993 and 1994 at 2 agricultural locations near Quebec City, Canada. Three raspberry systems, wild raspberry, pesticide-free cultivated raspberry, and commercial raspberry treated with a variety of pesticides, were sampled at frequent intervals. Tetranychus mcdanieli McGregor accounted for 87.5, 80.6, and 95.0...

Dispersal and competition have both been suggested to drive variation in adaptability to a new environment, either positively or negatively. A simultaneous experimental test of both mechanisms is however lacking. Here, we experimentally investigate how population dynamics and local adaptation to a new host plant in a model species, the two-spotted spider mite (Tetranychus urticae), are affected...

The carmine spider mite (CSM), Tetranychus cinnabarinus, is an important pest mite in agriculture, because it can develop insecticide resistance easily. To gain valuable gene information and molecular basis for the future insecticide resistance study of CSM, the first transcriptome analysis of CSM was conducted. A total of 45,016 contigs and 25,519 unigenes were generated from the de novo trans...

The main insect pests vary in different geographical areas. Studies have shown that the pomegranate biocenosis is dominated by such as Euzophera punicaella Mooze, Aphis punicae Theob, Pseudococcus komstoci Kuw, common spider (Tetranychus urticae Koch) damage was detected. Pomegranate juice gives 10-12 generations of pomegranates a year. These mainly orchards Tashkent region.

Phytoseiulus persimilis Athias-Henriot is an important biocontrol agent for controlling spider mites (Tetranychus spp). Rearing P. relatively expensive due to the need raise (e.g. Tetranychus urticae Koch), as prey, on live plants. Frozen eggs of T. can be easily stored and used a potential feed laboratory rearing persimilis. This study investigated performance frozen compared with fresh food U...

Ebu Mansûr Mâtürîdî (238- 333 /852-944) İslam düşünce tarihinde özel bir yere sahiptir. O, taraftan kelamcıların öncüsü, Müslümanların akaidini yanlışlardan arındıran bilgin, Ehl-i Sünnet anlayışının kurucusu, hidayet meşalesi ve önderi gibi sıfatlarla anılır. Diğer birçok ilim mezhep tarihçisi eserlerinde ona yer vermemiş, hatta takipçileri bazı görüşlerini Eş’arî anlayışa uydurmuşlardır. Mâtü...

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...

Tetranychus evansi Baker & Pritchard, 1960 (Tetranychidae) is a phytophagous mite with wide distribution and high importance for agriculture. This study reports the occurrence of T. in Nicotiana alata Link Otto, forgetiana Sander ex W. Watson (Solanaceae) their putative hybrids greenhouse Rio Grande do Sul state, Brazil. Different stages development were found N. hybrids.

two-spotted spider mite, tetranychus urticae koch (acari: tetranychidae), is one of the most injurious pests of fruits, vegetables and ornamental plants worldwide, both outdoor and indoors. currently the main method of control of this pest is through application of pesticides which is mostly accompanied by the resistance of the pest against pesticide(s). the resurgence of resistant mite populat...
