Hemipteran vectors of stylet‐borne plant viruses: Aphids lead the charge

open access: yesInsect Science, EarlyView.
Among all sap‐feeding hemipterans, aphids stand out by far as the most important vectors of noncirculative plant viruses. Compared to whiteflies and mealybugs, aphids’ highly specialized stylet anatomy and distinct feeding behaviors contribute, together with other features of their biology, to their remarkable efficiency in transmitting stylet‐borne ...

Reduced fertilization regimes could boost biocontrol service without reducing crop yield

open access: yesInsect Science, EarlyView.
Fertilization level influences pest control effectiveness in tomato crops. High fertilization increases plant growth and aphid density but reduces the performance of the parasitoid Aphidius ervi. In contrast, the predator Adalia bipunctata maintains consistent aphid suppression regardless of fertilization regime.

TcALS knockdown accelerates metamorphosis via insulin signaling in Tribolium castaneum

open access: yesInsect Science, EarlyView.
RNAi silencing of TcALS accelerates larva‐to‐pupa metamorphosis in Tribolium castaneum. Abstract Insect metamorphosis is an evolutionary adaptation precisely regulated by nutritional and hormonal cues. The red flour beetle Tribolium castaneum, a major stored‐product pest, serves as an excellent model for studying this process.

Consistent Choice of Prey Source Habitat Across Diverse Landscapes by a Selective Insectivorous Bat

open access: yesIntegrative Zoology, EarlyView.
After analyzing the diet of the greater horseshoe bats in three distinct colonies, we identified significant spatial and temporal differences, particularly noting a stronger reliance on riparian habitats in Mediterranean areas. The species exhibits great ecological adaptability with strong plasticity in prey source habitats, shifting preferences among ...

Supplementing beef cattle diets with brown seaweed affects coprophagous beetles' dung use

open access: yesAgricultural and Forest Entomology, EarlyView.
Supplementing beef cattle diets with brown seaweed reduced the attractiveness of dung for a common dung beetle (Onthophagus nuchicornis). Dietary supplementation with brown seaweed appeared to reduce the proportion of major males in the F1 generation.

Status of ash (Fraxinus spp.) in mixed hardwood post‐outbreak forests near the epicentre of the emerald ash borer invasion

open access: yesAgricultural and Forest Entomology, EarlyView.
The persistence and health of ash populations were characterized in post‐outbreak forests near the epicentre of the emerald ash borer (EAB) invasion in North America. Regenerating ash remained abundant, but densities of understory ash were higher in wetlands (hydric), while ash remained at the seedling stage in riparian (mesic) and upland (xeric ...

Host desiccation and interspecific competition limit reproductive performance of a bark beetle

open access: yesAgricultural and Forest Entomology, EarlyView.
At high and moderate phloem moisture levels, Polygraphus proximus reproductive success was suppressed by sympatric species density. At low phloem moisture, P. proximus reproductive success was suppressed by the low phloem moisture regardless of the Cryphalus laricis hole density. Conspecific density (i.e., attack density of P.

Comparing time‐lapse photography and traditional human observation in collecting crop pollinator visitation data Ajastetun valokuvauksen ja perinteisen suoran havainnoinnin vertailu kerättäessä tietoa pölyttäjien kukkakäynneistä viljelykasveilla

open access: yesAgricultural and Forest Entomology, EarlyView.
Time‐lapse photography with commercially available trail cameras provides a competitive alternative to direct human observations for documenting pollinator flower visits, but its performance varies between crops. In apple, the cameras recorded more diverse pollinator assemblages than the human observer due to larger temporal coverage of the camera ...

Where are they now? Establishment and impact reports of bark beetle biocontrol agents with a case study of introduced parasitoids from Southeast Queensland, Australia

open access: yesAgricultural and Forest Entomology, EarlyView.
Twenty‐four bark beetle biocontrol programmes involving 41 natural enemy introductions are reported globally. A total of 36.6% of agents were established and 9.8% were reported effective, while many agent establishments and impacts often remained unassessed and incomparable across regions.

Anatomical and Histological Structures of the Male Reproductive System of Chalcophora mariana (Linnaeus, 1758) (Coleoptera: Buprestidae): Light and Scanning Electron Microscopy Study

open access: yesActa Zoologica, EarlyView.
ABSTRACT This study presents the first detailed morphological analysis of the male reproductive system of Chalcophora mariana (Linnaeus, 1758) using stereo microscopy, light microscopy, and scanning electron microscopy. The male reproductive system of C.
