Biology of Neoseiulus californicus feeding on two-spotted spider mite

open access: yesBiotemas, 2013
Tetranychus urticae (Koch) stands out as a polyphagous mite. In a strawberry plant, this mite develops on the underside of leaves, causing a significant injury. This study aimed to know the biological characteristics of Neoseiulus californicus (McGregor), from cultivated strawberry plants.

The presence of webbing affects the oviposition rate of two-spotted spider mites, Tetranychus urticae (Acari: Tetranychidae) [PDF]

open access: yes, 2009
Several species of tetranychid mites including Tetranychus urticae Koch (Acari: Tetranychidae) construct complicated three-dimensional webs on plant leaves. These webs provide protection against biotic and abiotic stress.

Mate choice promotes inbreeding avoidance in the two-spotted spider mite [PDF]

open access: yesExperimental and Applied Acarology, 2011
Since inbreeding in Tetranychus urticae can reduce offspring fitness, sexual selection may favour disassortative mate choice with respect to relatedness of the mating partners. We tested whether T. urticae shows this preference for mating with unrelated partners.
