Impact of Host and Food Availability on Life‐History Traits in Six Egg Parasitoid Species of the Genus Trichogramma

Entomologia Experimentalis et Applicata, EarlyView.
In this study we measured the impact of access to sugar and hosts on the longevity and fecundity of six Trichogramma species: T. cacoeciae, T. chilonis, T. minutum, T. leptoparameron, T. pintoi and T. sibericum. The impact of food differed among species, but there was a general tendency of increased life expectancy and potential fecundity with sugar ...

Metabarcoding of Pollen Carried by Syrphids Reveals Novel Plant–Pollinator Interactions in a Protected Natural Area and Agricultural Sites

Entomologia Experimentalis et Applicata, EarlyView.
Using DNA metabarcoding, this study investigates pollen transported by syrphids (Syrphidae) in the Dolomiti Bellunesi National Park and agricultural sites in Northern Italy. The analysis reveals a high diversity of visited plant taxa, including previously undocumented plant–pollinator interactions.

Natural Parasitism of Nezara viridula (Linnaeus) (Hemiptera: Pentatomidae) by Trichopoda pictipennis Bigot (Diptera: Tachinidae) in an Organic Strawberry Field in Germany

Entomologia Experimentalis et Applicata, EarlyView.
Natural parasitism of the invasive southern green stinkbug was recorded in an organic strawberry cropping system in southwestern Germany. The tachinid fly Trichopoda pictipennis shows successful establishment and field activity, indicating ongoing range expansion.

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.

Behavioural responses to radio‐tag attachment in butterflies: Evidence for active tag removal

Ecological Entomology, EarlyView.
During controlled indoor flight experiments with 89 butterflies from eight tropical species, we monitored behavioural responses to dorsally attached radio tags using high‐speed video recordings. Four of 39 Morpho helenor exhibited coordinated abdominal flexion and hind leg movements directed toward the tag antenna during flight; in two individuals this
