Biology of the Gall Midge Spanolepis selloanae (Diptera, Cecidomyiidae), a Candidate Biological Control Agent of the Invasive Grass Cortaderia selloana

Entomologia Experimentalis et Applicata, EarlyView.
Spanolepis selloanae (Diptera, Cecidomyiidae) infests Cortaderia selloana (pampas grass). It lays eggs in the spikelets, where larvae feed on female parts. The high prevalence of the midge and its combined impact in seed production, condition and viability strongly reduces the reproductive output of C. selloana.

Assessing Predator Activity on Clay Models in Response to Common Insecticides in Turfgrass

Entomologia Experimentalis et Applicata, EarlyView.
Insecticides exhibited clear but time‐dependent effects on predatory activity, as reflected by impression types and density on clay models in turfgrass. Certain insecticides (bifenthrin, and in some cases acephate + imidacloprid, imidacloprid, chlorantraniliprole, and tetraniliprole) reduced total impressions shortly after application and again later ...

Behavioral Responses of Doryctobracon areolatus and Diachasmimorpha longicaudata (Hymenoptera: Braconidae) to Host Fruits Exploited by Heterospecific Competitors

Entomologia Experimentalis et Applicata, EarlyView.
Female parasitoids can lower competitive costs by detecting rival‐species cues on shared host fruits (host habitats). We compared native Doryctobracon areolatus and introduced Diachasmimorpha longicaudata on guava fruits infested with Anastrepha fraterculus.

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.

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

Ecological 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

Ecological 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.

Effects of non‐host traces on behavioural responses of an egg parasitoid to substrate‐borne semiochemicals in a multi‐herbivore scenario

Ecological Entomology, EarlyView.
In open arena assays, the response of the egg parasitoid Trissolcus basalis to substrate‐borne semiochemicals left by the host Nezara viridula was affected by the non‐host Spodoptera littoralis. Non‐host larval traces reduced T. basalis residence time spent on walking traces from gravid N. viridula females but did not affect responses to walking traces
