Life history of Amblyseius herbicolus (Chant) (Acari: Phytoseiidae) on coffee plants.
The predaceous mite Amblyseius herbicolus (Chant) is the second most abundant phytoseiid on coffee plants (Coffea arabica L), after Euseius alatus DeLeon, in Lavras, MG, Brazil, associated to the vector of the coffee ring spot virus, Brevipalpus phoenicis (Geijskes) (Acari: Tenuipalpidae). Its life history was studied taking into account biological aspects, life table, predatory activity and fu...
متن کاملPredation of Amblyseius longispinosus (Acari: Phytoseiidae) on Aponychus corpuzae (Acari: Tetranychidae)
Aponychus corpuzae is a pest of bamboo in Fujian, China. The predatory mite Amblyseius longispinosus was explored as a potential biocontrol agent against Ap. corpuzae in a series of experiments on its predation on Ap. corpuzae . The rate of prey consumption (per predator female) increased linearly with temperature from 1.35 at 15°C to 5.22 at 35°C (the relationship can be described by Y = -1.00...
متن کاملPrey Preference of the Predatory Mite, Amblyseius swirskii between First Instar Western Flower Thrips Frankliniella occidentalis and Nymphs of the Twospotted Spider Mite Tetranychus urticae
The prey preference of polyphagous predators plays an important role in suppressing different species of pest insects. In this study the prey preference of the predatory mite, Amblyseius swirskii (Athias-Henriot) (Acari: Phytoseiidae) was examined between nymphs of the twospotted spider mite, Tetranychus urticae Koch (Acari: Tetranychidae) and first instar larvae of the western flower thrips, F...
متن کاملEffects of starvation and humidity on the development and survival of Amblyseius swirskii, Agistemus exsertus and Amblyseius eharai
The ability of predatory mites to endure starvation or low humidity is very important for them to maintain their populations in unfavorable environments. The effects of starvation and humidity on the development and survival of Amblyseius (Typhlodromips) swirskii, Amblyseius eharai and Agistemus exsertus were studied in the laboratory. The results showed that most eggs of A. eharai and A. exser...
متن کاملCereal forage for dairy cattle
represents considerable thrips pressure. We present the data from yellow traps only to show that many thrips were present in the greenhouse throughout the trial. In the absence of predators, the number of thrips per plant increased consistently throughout the trial to reach 39.28 per plant in the final week (table 1). All treatments significantly reduced thrips numbers (P < 0.05) compared to th...
