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

open access: yesEntomologia 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 ...

Comparing Methods for Measuring Predation: Toward a Quantitative–Informative Indicator of Natural Pest Control

open access: yesEntomologia Experimentalis et Applicata, EarlyView.
Predation methods vary widely in their ability to quantify biological control. Estimating predation rates (the number of prey killed per predator per time unit) is crucial. Combining predation rates with predator abundance yields real‐time field estimates of pests consumed.

Automatic Potato Crop Beetle Recognition Method Based on Multiscale Asymmetric Convolution Blocks

open access: yesAgronomy
Five beetle species can occur in potato fields simultaneously, including one quarantine pest (the Colorado potato beetle (CPB)), one phytophagous pest (the 28-spotted potato ladybird beetle), and three predatory ladybird beetles (the 7-spotted lady ...

Quantifying Species‐ and Community‐Level Predation by Carabids on Pests and Beneficials in Wheat and Beet Fields

open access: yesEntomologia Experimentalis et Applicata, EarlyView.
Using a model that translates qualitative prey detection data (presence/absence in predator gut contents) into quantitative predation rates, we estimate species‐specific diets of nine carabid species across three cropping contexts (wheat, sugar beet, and fodder beet) for five prey types.

Plant Traits and Reproduction in a Multitrophic System: The Role of Aphids, Parasitoids and Hyperparasitoids

open access: yesEntomologia Experimentalis et Applicata, EarlyView.
This field mesocosm study examined the top‐down effects of hyperparasitoids, parasitoids and aphids on plant growth and fitness. Parasitoids reduced aphid populations, but this effect was attenuated by hyperparasitoids. However, these multitrophic interactions did not affect plant traits and reproduction, likely due to the plant's fast life cycle and ...

First record of Serangium montazerii (Coleoptera: Coccinellidae): A new exotic predator of Aleurocanthus spiniferus (Hemiptera: Aleyrodidae) in Greece

open access: yesEPPO Bulletin, EarlyView.
Abstract The biodiversity of Greek agroecosystems is constantly changing, with the influx of new species reshaping food webs. The present study contributes to the documentation of Greek fauna by reporting, for the first time, the occurrence of the Asian predatory ladybird Serangium montazerii Fürsch (Coleoptera: Coccinellidae). The species was detected
