Abstract:
... The relevance of interspecific resource competition in the context of community assembly by herbivorous insects is a well-known topic in ecology. Most previous studies focused on local species assemblies that shared host plants. Few studies evaluated species pairs within a single taxon when investigating the effects of host plant sharing at the regional scale. Herein, we explore the effect of plan ...

Abstract:
... Classic research on elevational gradients in plant–herbivore interactions holds that insect herbivore pressure is stronger under warmer, less seasonal climates characteristic of low elevations, and that this in turn selects for increased defence in low‐ (relative to high‐) elevation plants. However, recent work has questioned this paradigm, arguing that it overly simplifies the ecological complexi ...

Abstract:
... Oligophagous insects can consume a wide range of different host plant species, but how these host plants vary in their metabolite compositions and the extent to which this variation affects the biochemistry of the insect herbivores is largely unknown. An understanding of how defensive metabolites from plants are processed by insects may help us develop more effective pesticides. We studied the int ...

Abstract:
... Divergence and escalation in defences promote chemical diversity in plants, and consequently the diversity of insect herbivores. This diversification cascades to insect parasitoids through direct effects on host herbivore susceptibility, changes in herbivore community composition, or disparity in plant volatiles. Large tropical plant genera represent an ideal model for studying these trends due to ...

They are very common in the south of Syria, in particular in Damascus and Al Suwayda, and are found in fallow fields, pastures, roadsides and neglected areas. In 2015–2017, several sites with large populations of Onopordum spp. were identified. Weekly surveys of some of the sites, mainly in the regions of Dama ...

Abstract:
... Ecological niche indicators have been scarcely adopted to assess the biological control of insect herbivores by their natural enemies. We hypothesize that plant diversification promotes the biocontrol services by narrowing the niches of herbivores and broadening the niches of natural enemies. In a large-scale experiment, we found that the abundance of natural enemies was increased by 38.1%, and th ...

Abstract:
... Parasitoids (parasitic wasps) are ubiquitous components of nearly all communities containing plant–insect herbivore associations. Plant toxin defenses against herbivores may also affect higher trophic levels by directly (e.g., plant toxins encountered in host hemolymph) or indirectly (e.g., plant toxins reduce host size/quality or alter the host’s immunity against parasitoids). Yet, whether parasi ...

Abstract:
... Not all herbivory is detrimental to plants. In some cases, plants can compensate for herbivory, maintain growth and fitness following damage, or even overcompensate for herbivory and perform better than if left undamaged. Examples of overcompensation to vertebrate herbivory are well known, but here we review the literature for examples of reproductive overcompensation (i.e., increased production o ...

Although insect responses to these cues typically are assessed separately, in nature herbivores respond to olfactory and visual cues simultaneously. We demonstrate the functionality of a “double-stacked y-tube device” (D-SYD) to measure bioassay responses of a specialist herbivore to olfactory and visual cues of po ...

Abstract:
... Plants defend themselves against diverse communities of herbivorous insects. This requires an investment of limited resources, for which plants also compete with neighbours. The consequences of an investment in defence are determined by the metabolic costs of defence as well as indirect or ecological costs through interactions with other organisms. These ecological costs have a potentially strong ...

Abstract:
... Phenolics have a role in defenses against herbivores, but the defensive functions of specific groups of phenolics are still poorly understood. For example, ellagitannins (a type of hydrolyzable tannin) are predicted to decrease insect herbivore performance, but the effect of different types of ellagitannins on generalist and specialist herbivores has rarely been assessed. Here, we test the effects ...

Abstract:
... Herbivore‐plant interactions should be studied using a tri‐trophic approach, but we lack a quantitative measure of the combined effect of top‐down and bottom‐up forces on herbivore fitness. We propose the combination of the bi‐trophic fitness slopes as a tri‐trophic fitness measure. We use the relationship between fitness associated with top‐down and bottom‐up forces and the frequency of host plan ...

We conducted a factorial fertilisation experiment manipulating macron ...

Abstract:
... Plant volatiles are used not only by herbivorous insects to find their host plants, but also by the natural enemies of the herbivores to find their prey. There is also increasing evidence that plant volatiles, in addition to species-specific pheromones, help these insects to find mating partners. Plant structures such as flowers, fruit, and leaves are frequently rendezvous sites for mate-seeking i ...
