Occasional reports linking neonicotinoid insecticide applications to field population outbreaks of the spider mite have been a topic of concern for integrated pest management programs. To elucidate the impacts of a neonicotinoid insecticide on the carmine spider mite, Tetranychus cinnabarinus Boisduval (Acari: Tetranychidae), the survivorship, reproduction, and vitellin contents of the mite wer...

the effect of fenpyroximate on life table parameters of two-spotted spider mite tetranychus urticae koch was evaluated under laboratory conditions (25±20c, 60±5% rh and 16:8 l:d). data were analyzed on the basis of age-stage, two-sex life table theory. the estimated value of lc50 for t. urticae was found to be 380 ml/l. durations of total preadult stage and preoviposition period in t. urticae t...

Remote sensing techniques can decrease pest monitoring costs in orchards. To evaluate the feasibility of detecting spider mite damage in orchards, we measured visible and near infrared reflectance of 1153 leaves and 392 canopies in 11 peach orchards in California. Pairs of significant wavelengths, identified by Partial Least Squares regression, were combined into normalized difference indices. ...

European red mites are the most frequent mite in Uzbekistan apple orchards, and they may be found from early spring through harvest. The orange-colored adults of twospotted spider overwinter beneath bark trees or on weeds. In spring, populations typically cluster tree nearby areas broadleaf weeds, brambles, sucker growth. Damage. Twospotted induce bronzing leaves. Spider leave a characteristic ...

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...

the entomopathogenic fungus beauveria bassiana (bals.) vuill. is one of the important arthropod pathogens that can play an important role in the regulation of mite populations in agricultural ecosystems. in this study, the combined effect of a native isolate of fungus b. bassiana (eut105) and ether-extract of plant, ginkgo biloba was evaluated against the two-spotted spider mite, tetranychus ur...
