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

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

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

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.

What omnivores don't eat : Nonconsumptive ecological effects of phytophagy by Macrolophus pygmaeus

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.

Herbaceous Weeds as Potential Host Plants for Tetranychus urticae and Predation Efficacy of Typhlodromips capsicum on Preferred Host Plants

Tetranychidae), is one of the most serious polyphagous pests worldwide. During intercropping periods, TSSM transfers to available green plants either economic or weeds. The objective of the current

Foraging and antipredator behaviour in an acarine predator-prey system on tomato

Investigation of whether the predatory mites P. longipes and P. macropilis can find and discriminate between prey through perception of cues from infested plants finds that these predators are able to recognize T. evansi.

Efficiency against the Two-spotted spider mite Tetranychus urticae and prey-age-related choice of three predatory mites

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.

Antipredator response of pea aphids Acyrthosiphon pisum (Hemiptera: Aphididae): effects of predation risks from an alternative patch on a current patch

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.

Lima bean leaves exposed to herbivore-induced conspecific plant volatiles attract herbivores in addition to carnivores

The response of the herbivorous mite Tetranychus urticae to uninfested lima bean leaves exposed to herbivore-induced conspecific plant volatiles is tested by using a Y-tube olfactometer and the role of the volatile from the exposed plants in a tritrophic system is discussed.
