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.

The Parasitoid Wasp Glyptapanteles porthetriae Induces a Photoperiod‐Dependent Diapause‐Like State in Its Potential Overwintering Host Lasiocampa quercus

open access: yesEntomologia Experimentalis et Applicata, EarlyView.
We evaluated Lasiocampa quercus as an overwintering host for the koinobiont larval endoparasitoid Glyptapanteles porthetriae by exposing parasitized larvae to different environmental conditions and comparing parasitoid development with that in the primary host Lymantria dispar.

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.

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

open access: yesEntomologia 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.
