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 ...

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.

How much sampling is enough? Four decades of understorey bird mist‐netting across Amazonia define the minimum effort to uncover species assemblage structure

Ibis, EarlyView.
Mist‐net sampling comprises a key methodological component of assemblage‐wide avifaunal studies, particularly in the understorey of closed‐canopy tropical forests. To investigate mist‐net bird captures and species assemblage structure, we compiled data from 312 sites across the Pan‐Amazon.
