the developmental period, prey consumption of different nymph instars, survival, reproduction and longevity of orius albidipennis were studied on three different diets including the two-spotted spider mite, tetranychus urticae plus corn pollen; two-spotted spider mite; and eggs of sitotroga cerealella plus corn pollen under laboratory conditions. leaves of pelargonium hortom served as ovipositi...

repeatability, (the consistency with which a given trait is expressed) of aggressiveness against prey (attack latency) in gravid females of the predatory mite neoseiulus californicus (mcgregor) was examined. in two experiments, prey - conspecific individuals, the onion thrips thrips tabaci (lindeman), and the two-spotted spider mite tetranychus urticae koch- were repeatedly offered in various n...

The two-spotted spider mite, Tetranychus urticae Koch, is a constant threat to sustainable production of numerous economically important crops globally. Management T. heavily reliant on the application synthetic acaricides. However, has rapidly developed resistance most acaricides available for its control due very broad host plant range, extremely short lifecycle, high fecundity, arrhenotokous...

This paper presents and compares four mathematical models with unique spatial effects for a prey-predator system, with Tetranychus urticae as prey and Phytoseiulus persimilis as predator. Tetranychus urticae, also known as two-spotted spider mite, is a harmful plant-feeding pest that causes damage to over 300 species of plants. Its predator, Phytoseiulus persimilis, a mite in the Family Phytose...

The two-spotted spider mite, Tetranychus urticae Koch (Acari: Tetranychidae) is a cosmopolitan pest that causes considerable damage to vegetables, fruit and flower plants. acaricidal, ovicidal repellent activity of four different extracts Aloe vera L. (Asphodelaceae) leaves were evaluated against T. under laboratory conditions. Four solvents A. leaf tested at concentrations 0.25, 0.50, 1.0 2.0%...

Tetranychus urticae is one of the most important pests of strawberry cultures in Morocco. Current control of this pest relies almost exclusively on acaricides. Unfortunately, this mite has developed resistance to most of the available acaricides. Moreover, insecticide treatments are responsible for the reduction or suppression of beneficial species such as natural predators. Thus, identificatio...

Tetranychus urticae (T. urticae) Koch is a cosmopolitan, polyphagous mite which causes economic losses in both agricultural and ornamental plants. Some traits of T. urticae hamper its management, including a short life cycle, arrhenotokous parthenogenesis, its haplodiploid sex determination system, and its extraordinary ability to adapt to different hosts and environmental conditions. Currently...
