Predator avoidance in phytophagous mites: response to present danger depends on alternative host quality

We studied whether volatiles released by putative host plants affect the antipredator response of an herbivorous mite, Tetranychus urticae, when the patch was invaded by Phytoseiulus persimilis. Tetranychus urticae laid a lower number of eggs on tomato leaves than on lima bean leaves, suggesting that lima bean is a preferred host food source for T. urticae. In addition, T. urticae preferred lima bean plant volatiles to tomato plant volatiles in a Y-tube olfactometer test. To investigate the…

Predator Avoidance by Phytophagous Mites is Affected by the Presence of Herbivores in a Neighboring Patch
- Environmental ScienceJournal of Chemical Ecology
- 2010
This work used laboratory bioassays to examine whether perception of odor from con- or heterospecific competitors on a neighbored lima bean leaf patch influences dispersal behavior of the herbivorous mite Tetranychus urticae when attacked by predatory mites Phytoseiulus persimilis.
Predation-related odours reduce oviposition in a herbivorous mite
- Environmental Science, BiologyExperimental and Applied Acarology

Data suggest that the presence of T. urticae, P. persimilis and a leaf patch are needed for the emission of odours to reduce oviposition in T. Urticae.
Antipredator responses in Tetranychus urticae differ with predator specialization
- Environmental Science
- 2016
The behavioural response of Tetranychus urticae to chemical cues from specialist predatory mites, Phytoseiulus persimilis, or generalist predatory bugs on either bean or strawberry was studied, emphasizing the importance of specialization in the predator species complex for the degree and type of antipredator responses and resulting biological control.

It is shown that the omnivore induces direct plant defences in sweet pepper plants, which negatively affects the performance of two of three of its prey: spider mites and thrips, but not of aphids.
Effect of a heterospecific predator on the oviposition behavior of Phytoseiulus persimilis

The oviposition rate of Phytoseiulus persimilis was examined for a response for signals emanating from its heterospecific competitor, Frankliniella occidentalis in the presence of their shared prey, Tetranychus urticae on rose and bean leaf patches.
The role of leaf volatiles in predator avoidance by phytophagous mites

This study studied whether the herbivorous mites change their dispersal to the alternative patch with either conspecifics, or cowpea aphids, or common cutworms when they perceived volatiles from the patch infested by the competitors.

The results suggest that the generalist A. swirskii, but not I. degenerans, may be efficient in regulating prey populations through egg consumption, and represents an alternative to the effective specialist predator.

Odors of both adult ladybirds and of conspecifics being attacked by ladybird larvae were required for reduced leaving, suggesting predation risks on current and alternative patches might affect the antipredator responses of aphids.
