Plant Traits and Reproduction in a Multitrophic System: The Role of Aphids, Parasitoids and Hyperparasitoids

open access: yesEntomologia Experimentalis et Applicata, EarlyView.
This field mesocosm study examined the top‐down effects of hyperparasitoids, parasitoids and aphids on plant growth and fitness. Parasitoids reduced aphid populations, but this effect was attenuated by hyperparasitoids. However, these multitrophic interactions did not affect plant traits and reproduction, likely due to the plant's fast life cycle and ...

Do aphid endosymbiotic bacteria influence parasitoid searching behaviour through changes in aphid honeydew production?

open access: yesEcological Entomology, EarlyView.
Hamiltonella defensa infection increases honeydew production in certain aphid genotypes, potentially modifying aphid feeding behaviour. Parasitoid wasps, Aphidius ervi, are more attracted to honeydew from H. defensa‐infected aphids; though larger honeydew amounts may slightly deter searching.

A defensive symbiont and a plant virus confer direct and discrete phenotypes to a cereal aphid in a context‐dependent manner

open access: yesEcological Entomology, EarlyView.
Different BYDV‐PAV isolates exert contrasting effects on aphid fitness, including reproduction and winged production. Different BYDV‐PAV isolates have contrasting effects on aphid dispersal patterns. Aphid feeding behaviour is modulated by the presence of endosymbionts and plant viruses.

First record of Serangium montazerii (Coleoptera: Coccinellidae): A new exotic predator of Aleurocanthus spiniferus (Hemiptera: Aleyrodidae) in Greece

open access: yesEPPO Bulletin, EarlyView.
Abstract The biodiversity of Greek agroecosystems is constantly changing, with the influx of new species reshaping food webs. The present study contributes to the documentation of Greek fauna by reporting, for the first time, the occurrence of the Asian predatory ladybird Serangium montazerii Fürsch (Coleoptera: Coccinellidae). The species was detected

She Doesn't Whisper: Female‐Prominent Stridulation Shaped by Morphology in a Buthid Scorpion and Insights on Its Function

open access: yesEthology, EarlyView.
Sexual dimorphism and stress‐induced stridulatory responses in Jaguajir rochae (Borelli, 1910). Females exhibited greater absolute pectinal size and higher sound pressure levels, whereas males showed higher pectinal allometric ratios relative to body size, lower sound frequencies, and shorter delta times.
