A herbivore that manipulates plant defence

The spider mite Tetranychus evansi suppresses the induction of the salicylic acid and jasmonic acid signalling routes involved in induced plant defences in tomato, providing a new perspective on plant–herbivore interactions, plant protection and plant resistance to invasive species.
Phytoseiid predators as potential biological control agents for Bemisia tabaci

Predatory mites found to co-occur with whiteflies in the Middle East for control of B. tabaci indicate that some of the species should be capable of suppressing local populations of whitefly, and the ability of predators to use alternative food was tested.
Habitat structure affects intraguild predation.

Habitat structure may increase persistence of the intrag guild prey by decreasing the strength of the interaction between intrag Guild predator and intraguild prey.
Odour-mediated responses of phytophagous mites to conspecific and heterospecific competitors

Investigating the response of one species of herbivore to odours emanating from cucumber plants infested by conspecific or heterospecific herbivores found that spider mites prefer clean plants over thrips-infested plants, since thrips are not only competitors, but are also known as intraguild predators of spider mite.
Herbivore arthropods benefit from vectoring plant-viruses

It is proposed that plant pathogens in general have evolved mechanisms to overcome plant defences against their vectors, thus promoting pathogen spread.
INTRAGUILD PREDATION USUALLY DOES NOT DISRUPT BIOLOGICAL CONTROL

It is clear that intraguild predation most often does not increase pest densities as was predicted from theory, but more research is needed to reveal why theory does not meet practice.
Biological control of thrips and whiteflies by a shared predator: Two pests are better than one

Evolution of Life-History Patterns in the Phytoseiidae
- M. Sabelis, A. Janssen
- Biology
- 1994
The approach taken here is to formulate hypotheses independent of the actual life-history data, because there is a danger that the range of species studied is biased towards phytoseiids that are successful predators of economically important plant mites.
Mechanisms and ecological consequences of plant defence induction and suppression in herbivore communities.

- 1 June 2015
Herbivores have evolved diverse strategies to decrease the negative effects of plant defences in order to maximize the conversion of plant material into offspring, and the ability to suppress induced plant defences appears to occur across plant parasites from different kingdoms.
Phytoseiid predators of whiteflies feed and reproduce on non-prey food sources

Biological control of whiteflies may benefit from both pollen and honeydew because these non-prey food sources have a positive effect on the life history of the two predator species, especially E. scutalis.
