Plant-feeding may explain why the generalist predator Euseius stipulatus does better on less defended citrus plants but Tetranychus-specialists Neoseiulus californicus and Phytoseiulus persimilis do not

Ambulatory and Aerial Dispersal Among Specialist and Generalist Predatory Mites (Acari: Phytoseiidae)
Predator-prey systems having a specialist predator often are over-exploitive, unstable and transient while similar systems having a generalist predator show less ßuctuation, more stability and regulation of prey at lower densities. These population dynamics also affect dispersal patterns between specialist and generalist predators. In this study, ambulatory and aerial dispersal were assessed fo...
متن کاملSex-specific developmental plasticity of generalist and specialist predatory mites (Acari: Phytoseiidae) in response to food stress
We studied developmental plasticity under food stress in three female-biased size dimorphic predatory mite species, Phytoseiulus persimilis, Neoseiulus californicus, and Amblyseius andersoni. All three species prey on two-spotted spider mites but differ in the degree of adaptation to this prey. Phytoseiulus persimilis is a specialized spider mite predator, N. californicus is a generalist with a...
متن کاملAttraction of Phytoseiulus persimilis (Acari: Phytoseiidae) towards volatiles from various Tetranychus urticae-infested plant species.
Plants infested with the spider mite Tetranychus urticae Koch, may indirectly defend themselves by releasing volatiles that attract the predatory mite Phytoseiulus persimilis Athias-Henriot. Several plants from different plant families that varied in the level of spider mite acceptance were tested in an olfactometer. The predatory mites were significantly attracted to the spider mite-infested l...
متن کاملFood stress causes sex-specific maternal effects in mites
Life history theory predicts that females should produce few large eggs under food stress and many small eggs when food is abundant. We tested this prediction in three female-biased size-dimorphic predatory mites feeding on herbivorous spider mite prey: Phytoseiulus persimilis, a specialized spider mite predator; Neoseiulus californicus, a generalist preferring spider mites; Amblyseius anderson...
متن کاملHow Does Phytoseiulus Persimilis Find Its Prey When Foraging within a Bean Plant?
The role of herbivore‐induced volatile substances in prey‐finding by phytoseiid mites has been repeatedly documented using an olfactometer. The objective of the present paper is to test the hypothesis that movement by Phytoseiulus persimilis is affected by these volatiles even on plants. Two series of laboratory experiments were carried out. In the first series we stud...
