Characterization of the dynamic microbiome evolution across thrips species

open access: yesInsect Science, EarlyView.
Comprehensive survey of the microbiome in thrips. The dominant bacterial genera found in thrips include intracellular ones, such as Wolbachia and Spiroplasma, and extracellular ones, including Serratia, Pantoea, and Acinetobacter. We isolated and sequenced high‐quality genomes of two dominant symbionts, Pantoea dispersa and Serratia marcescens.

RNAi‐based functional genomics tools for the beet leafhopper using microinjection and nanoparticle‐based topical spray

open access: yesInsect Science, EarlyView.
• First demonstration of functional RNAi in the beet leafhopper, Neoaliturus tenellus, using both dsRNA microinjection and star polycation nanoparticle‐mediated topical spray delivery.•Microinjection achieved over 90% knockdown of Gus and Pum3, revealing gene‐specific fitness effects on survival and fecundity in beet leafhopper.•Nanoparticle‐mediated ...

A horizontally acquired pantothenate gene drives vitellogenin's benefit to whitefly symbiosis persistence

open access: yesInsect Science, EarlyView.
This diagram illustrates that the horizontally transferred panBC influences the level and localization of vitellogenin (Vg) by facilitating pantothenate production and juvenile hormone (JH) biosynthesis. In turn, Vg shields symbionts by suppressing autophagic degradation in bacteriocytes.

Aphid and endosymbiont sensitivity to heatwaves is misaligned across life stages

open access: yesInsect Science, EarlyView.
Aphids depend on the obligate symbiont Buchnera aphidicola, which may constrain thermal tolerance. Using a factorial heatwave experiment, we exposed nymphs and adults to moderate or extreme temperatures and measured fitness and symbiont responses.

Assessing the host plants of the invasive apricot aphid, Myzus mumecola (Hemiptera: Aphididae)

open access: yesAgricultural and Forest Entomology, EarlyView.
We investigated the host plants of the invasive apricot aphid Myzus mumecola (Hemiptera: Aphididae), an emerging pest species in Europe, by combining molecular and ecological approaches. The winter host plant was confirmed as apricot by both methods.

Neonicotinoid seed treatments do not consistently reduce insect feeding damage nor increase yields in Maryland soy

open access: yesAgricultural and Forest Entomology, EarlyView.
We compared soybean plants from untreated and treated seeds across 4 sites and 3 years in Maryland. Neonicotinoid seed treatments (NST) provided little reduction in insect stippling damage and no reduction in chewing damage. NST did not result in increased plant biomass or bean yield. Abstract The use of neonicotinoid insecticides in seed treatments in

Evidence for positive population‐level responses but not individual performance of sycamore aphids under elevated CO2

open access: yesAgricultural and Forest Entomology, EarlyView.
The abundance and density of three common sycamore aphids increased under elevated CO2, although this was only statistically significant for Drepanosiphum platanoidis. The number of nymphs produced by individual D. platanoidis alates isolated in clip cages was not significantly affected, suggesting that population level response was not driven by ...

Determinants of variation in the response of the aphid parasitoid Aphidius ervi to aphid sex pheromones [PDF]

open access: yes, 2008
Variation in parasitoid responses to semiochemicals may be influenced by genetics, phenotypic plasticity and the individual\u27s physiological state. Previous experimental work has indicated a high degree of variability among parasitoid individuals in ...

Ants contribute to raspberry pollination in protected cropping systems

open access: yesAgricultural and Forest Entomology, EarlyView.
Ants visited raspberry flowers more frequently than European honey bees (Apis mellifera), Australian stingless bees (Tetragonula carbonaria) and flies, many transporting raspberry pollen on their bodies, indicating potential pollination capacity. Ants were active flower visitors at most times of the day and may extend the daily pollination window and ...
