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...

abstract common bean (phaseolus vulgaris l.) is one of the most important crops in lorestan province with about 23000 ha. in this area, two spotted spider mite (tssm) tetranychus urticae koch is the key pest of this crop. to study the effect of macroelements (npk) fertilizers, on controlling tssm and their effect on some agronomic characters of derakhshan bean cultivar, two same trails (1. trea...

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...

The two-spotted spider mite, Tetranychus urticae, is an important pest of horticultural crops worldwide and has developed resistance against multiple kinds pesticides. To date, information on the to pesticides inadequate for T. urticae populations in Hainan, south China. In current study, we determined seven five field that were collected cucurbit Hainan 2021. results showed high extremely abam...

Biological control can be severely disrupted by hot and dry environmental conditions associated with climate change. These may alter the food web configuration of arthropod communities through their effects on species interactions. They could disrupt competition between phytoseiid predators Euseius stipulatus, Neoseiulus californicus, Phytoseiulus persimilis, which are key natural enemies Tetra...

In this study, in order to find novel biologically active pyrazole oxime derivatives, twenty-eight new pyrazole oxime compounds containing a substituted isoxazole ring were synthesized and evaluated for their acaricidaland insecticidal activities. Bioassays exhibited that some target compounds indicated good acaricidal and insecticidal activities against Tetranychus cinnabarinus, Aphis medicagi...

Tetranychus urticae (Acari: Tetranychidae) is a phytophagous mite that forms colonies of several thousand individuals. Like spiders, every individual produces abundant silk strands and is able to construct a common web for the entire colony. Despite the importance of this silk for the biology of this worldwide species, only one previous study suggested how to visualize it. To analyze the web st...

today, with the advanced statistical techniques and neural networks, predictive models of distribution have been rapidly developed in ecology. purpose of this research is to predict and map the distribution of tetranychus urticae koch (acari: tetranychidae) using mlp neural networks combined with genetic algorithm in surface of farm. population data of pest was obtained in 2016 by sampling in 1...
