Generation Rather Than Sex Shapes Wing Morphology in Cydalima perspectalis (Lepidoptera, Crambidae): Insights From Geometric Morphometrics and Climate‐Based Projections

Entomologia Experimentalis et Applicata, EarlyView.
An integrated framework combining geometric morphometrics and ecological niche modeling was applied to Cydalima perspectalis to assess intergenerational morphological variation, test sexual dimorphism, and predict future distribution under climate scenarios. Wing shape effectively discriminated between generations but not between sexes.

Insect herbivory response to Populus nigra genetic diversity

, 2010
Recent research suggests that genetic diversity in tree population may shape associated species assemblages and then drive ecosystem processes. Trees can support large numbers of insect species and some functional traits of trees have been shown to have ...

Birch Leaves as a Minefield: Do Trichomes Mediate Neonate Caterpillar Site Selection?

Entomologia Experimentalis et Applicata, EarlyView.
We investigated whether neonate Drepana arcuata caterpillars select leaf sites based on trichome distribution. Specifically, we assessed where larvae establish on leaves, quantified trichome distribution on leaves, and tested whether neonates avoid leaf trichomes. Neonates preferentially established and fed on areas with fewer trichomes, especially the

Methyl Jasmonate and Methyl Salicylate Differentially Modulate Direct and Indirect Defenses in Coffee Plants Against the White Mealybug

Entomologia Experimentalis et Applicata, EarlyView.
MeJA application strengthened both direct and indirect coffee defenses against the white mealybug Planococcus citri, whereas the effects of MeSA were variable and context‐dependent across the defensive traits examined. The combined application of both elicitors produced an effect similar to MeSA on direct defenses, but resembled MeJA when indirect ...

Insect herbivory releases more nutrients in warmer and drier forests

Climate, forest successional stage, and soil substrate age can alter herbivore communities and their effects on biogeochemical cycling, but the size and spatial variability of these effects are poorly quantified.

Two Metschnikowia nectar yeast species have similar volatile profiles but elicit differential foraging in bee pollinators

Ecological Entomology, EarlyView.
Yeasts that specialize in flower nectar play an important role in pollination ecology. Metschnikowia reukaufii and Metschnikowia koreensis were the most prevalent nectar yeasts found in our field sites. Bee pollinators exhibited different behavioural responses to nectar yeasts in field experiments. Bees visited more flowers with M.

GLOBAL MODELS OF HERBIVORY VARIABILITY: DATA FROM THE HERBVAR PROJECT [PDF]

Herbivory is a major selection pressure on plants, which have evolved many different physical and chemical adaptations to prevent animals from eating their tissues. Mean herbivory patterns have been well studied in ecology.

Does the munch affect the bunch? Using community science to explore insect herbivory and fruit production in an understory plant

Ecological Entomology, EarlyView.
We used iNaturalist records, a longitudinal field survey, and a simulated herbivory experiment to explore how insect herbivory factors are associated with Cornus canadensis fruit production. Naturally observed internal and external insect herbivory was mostly low intensity and did not have a strong relationship with fruit production.

Parasitic wasp‐associated polydnavirus and venom affect arthropod community assembly on wild cabbage via the caterpillar host

Ecological Entomology, EarlyView.
Cotesia glomerata polydnavirus and venom, either alone or in combination, affect colonisation by members of the arthropod community in a natural field setting. Plants damaged by P. brassicae injected with both polydnavirus and venom were colonised more often by Mamestra brassicae caterpillars, Myzus persicae aphids and aphid parasitoids compared to ...

Temperature elevation broadens the dietary niche of an insect herbivore

Ecological Entomology, EarlyView.
The realised dietary niche in Chrysomela lapponica was the narrowest at 10°C, whereas higher temperatures (15–25°C) broadened the dietary niche by increasing preference for and survival on suboptimal host plants. Elevated temperature broadened the realised dietary niche through both direct effects on beetles and indirect effects mediated by temperature‐
