Herbivory-Induced Stomatal Opening Triggers the Dispersal of an Invasive Insect Herbivore. [PDF]

Adv Sci (Weinh)
The invasive leafminer Phthorimaea absoluta uniquely manipulates plant defenses by inducing stomatal opening in tomato. This response, mediated by the stomatal regulator IQM1, enhances the release of the repellent volatile benzaldehyde. This volatile triggers the dispersal of adult moths, facilitates colonization of new hosts, and leads to rapid ...

Water availability and plant-herbivore interactions. [PDF]

, 2022
Water is essential to plant growth and drives plant evolution and interactions with other organisms, such as herbivores. However, water availability fluctuates, and these fluctuations are intensified by climate change.

Experimental support of the stress‐gradient hypothesis in herbivore–herbivore interactions [PDF]

New Phytologist, 2012
Summary The stress‐gradient hypothesis (SGH) postulates an increase in the frequency of positive species interactions at increasing amounts of stress. While the SGH has been extensively tested in plant–plant interactions along abiotic stresses, it remains unclear whether this hypothesis could apply to higher trophic levels, such as herbivores, along ...

Noncrop flowering plants restore top-down herbivore control in agricultural fields [PDF]

, 2013
Herbivore populations are regulated by bottom-up control through food availability and quality and by top-down control through natural enemies. Intensive agricultural monocultures provide abundant food to specialized herbivores and at the same time ...

Prey and Non-prey Arthropods Sharing a Host Plant: Effects on Induced Volatile Emission and Predator Attraction [PDF]

, 2008
It is well established that plants infested with a single herbivore species can attract specific natural enemies through the emission of herbivore-induced volatiles.

Population-related variation in plant defense more strongly affects survival of an herbivore than its solitary parasitoid wasp [PDF]

, 2011
The performance of natural enemies, such as parasitoid wasps, is affected by differences in the quality of the host’s diet, frequently mediated by species or population-related differences in plant allelochemistry. Here, we compared survival, development

Plant volatiles as regulators of plant defense and herbivore immunity: molecular mechanisms and unanswered questions [PDF]

, 2021
Plants release distinct blends of herbivore-induced plant volatiles (HIPVs) upon herbivore attack. HIPVs have long been known to influence the behavior of herbivores and natural enemies.

Plant defense and herbivore counter-defense: benzoxazinoids and insect herbivores [PDF]

Phytochemistry Reviews, 2016
Benzoxazinoids are a class of indole-derived plant chemical defenses comprising compounds with a 2-hydroxy-2H-1,4-benzoxazin-3(4H)-one skeleton and their derivatives. These phytochemicals are widespread in grasses, including important cereal crops such as maize, wheat and rye, as well as a few dicot species, and display a wide range of antifeedant ...

Differential effects of jasmonic acid treatment of Brassica nigra on the attraction of pollinators, parasitoids, and butterflies [PDF]

, 2008
Herbivore-induced plant defences influence the behaviour of herbivores as well as that of their natural enemies. Jasmonic acid is one of the key hormones involved in both these direct and indirect induced defences.

Performance of specialist and generalist herbivores feeding on cabbage cultivars is not explained by glucosinolate profiles [PDF]

, 2008
Plants display a wide range of chemical defences that may differ in effectiveness against generalist and specialist insect herbivores. Host plant-specific secondary chemicals such as glucosinolates (GS) in Brassicaceae typically reduce the performance of
