A First Indication That Rainforest Vine Proliferation Does Not Enhance Predator–Prey Interactions on the Forest Floor

open access: yesEntomologia Experimentalis et Applicata, EarlyView.
Vine proliferation is a widespread consequence of tropical forest disturbance, yet its effects on ground‐level predator–prey interactions remain poorly understood. Using plasticine caterpillars deployed on the rainforest floor in north Queensland, Australia, we show that overall predation rates were unaffected by vine‐to‐tree ratio. Instead, fine‐scale

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

open access: yesEntomologia 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.

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

open access: yesEntomologia 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

open access: yesEntomologia 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 ...

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

open access: yesEcological 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.

Inducible tomato defences persist in detached leaves, despite differential plant variety and gene‐dependent expression

open access: yesEcological Entomology, EarlyView.
Short‐ and long‐term expression of PPO‐D, PI‐IIc and PR‐1a were assessed in intact plants and detached tomato leaves of two varieties infested with Tetranhycus urticae. Tomato defences were induced in both intact and detached leaves, but the induction levels varied with plant variety and gene assessed.
