Subject:
Aphididae; Cameraria ohridella; Cecidomyiidae; Euura; invasive species; Armenia
Abstract:
... In July 2019 four species of invasive alien phytophagous insects were recorded during the surveys of woody green spaces in Dilijan (Armenia): Cameraria ohridella Deschka et Dimić, 1986 (Lepidoptera: Gracillariidae), Obolodiplosis robiniae (Haldeman, 1847) (Diptera: Cecidomyiidae), Prociphilus (Meliarhizophagus) fraxinifolii (Riley, 1879) (Hemiptera: Aphididae) and Euura tibialis Newman, 1837 ...

Abstract:
... Chlorophyll (Chl) is a natural compound that is found in all autotrophic plants. Since phytophagous insects ingest the photosynthetically active material with the plant leaves, the question arises if and how herbivores deal with Chl and its degradation products. Here we review findings on Chl degradation in phytophagous insects and highlight the role of these ubiquitous plant metabolites ...

Abstract:
... The development and physiological status of pest insects are important factors that affect the effectiveness of biological control. Current knowledge reveals that heavy metals can be transferred to phytophagous insects through food chains and cause various chronic toxicological effects on the growth and physiology of phytophagous insects. These findings potentially attribute heavy metal ...

Abstract:
... The density of phytophagous insect pest populations is related (directly and indirectly) to several groups of factors that can be broadly divided into: abiotic, biotic and anthropogenic. Each extreme in the abiotic environment at a macro-level leads to a series of consecutive extremes in the biotic environment, which eventually results in micro-level responses in the individual organisms ...

Abstract:
... Insect herbivores require a variety of habitats across their life cycle, with behavior often mediating transitions between life stages or habitats. Human management strongly alters urban habitats, yet herbivore behavior is rarely examined in cities. We review the existing literature on several key behaviors: host finding, feeding, egg placement and pupation location, and antipredator defense. We e ...

Abstract:
... Host specificity of phytophagous insects plays a critical role in the maintenance of plant diversity. However, a lack of approaches to identify the larvae of phytophagous insects, which usually have similar morphology, can lead to misinterpretation of their host ranges. Acorn weevils are seed‐exploiting parasites of Fagaceae species, a dominant plant group in subtropical evergreen broad‐leaved ...

Abstract:

Hence, we tested the hypothesis that the efficiency of these food-based buffering mechanisms may vary between different larval instars of a phytophagous insect. Using larvae of the moth Lobesia botrana, we examined the importance of post-stress food quality in insect ...

Abstract:
... Recursive adaptations and counter‐adaptations of plant‐feeding insects are thought to have driven chemical and physical diversity in plant defenses. Among existing theories on defensive diversity, the syndromes hypothesis predicts that plants may evolve suites of covarying defense traits along evolutionary arms races with herbivores. We use the large, phenotypically diverse angiosperm genus Ficus ...

Abstract:
... Sodium (Na) is an essential element for all animals, but not for plants. Soil Na supplies vary geographically. Animals that primarily consume plants thus have the potential to be Na limited and plants that uptake Na may be subject to higher rates of herbivory, but their high Na content also may attract beneficial partners such as pollinators and seed dispersers. To test for the effects of Na bioge ...

Although the induction of this ‘cry for help’ has been well documented, only a few studies have investigated the inhibition of HIPVs by herbivores and little is known about whether herbivores have evolved mechanisms to inhibit the release of HIPVs. To examine ...

Abstract:
... Arbuscular mycorrhizal (AM) fungi are ubiquitous symbionts of most terrestrial plants that can augment plant defences against insect herbivores. A clearer understanding of the mechanisms underpinning community-specific effects of AM fungi on plant resistance to herbivores is needed. Here, we report how plant (Triticum aestivum) phenolic-based resistance to an insect herbivore is differentially aff ...

Abstract:
... To predict shrub responses under climate change in tundra, we need to understand how thermal conditions and herbivory contribute to growth. We hypothesise that shrub growth increases with thermal conditions and precipitation, but that this increase is counteracted by insect herbivory, and that these climate–insect herbivory relationships are modified by both browsing and plant age. We use empirica ...

In a warming world, changes in climate may result in species‐level responses as well as changes in community structure through knock‐on effects on ecological interactions such as predation and herbivory. Yet, the links between these responses at different levels are still inadequately understood. Assessing how microclimatic conditions affect each of them at local scales provides information essent ...
