Degree of insecticide exposure and access to nectar impact survival of Trissolcus japonicus, a hymenopteran parasitoid, in flowering border strips

Agricultural and Forest Entomology, EarlyView.
We applied three thiamethoxam spray treatments to buckwheat border strips: control (no nearby spray), drift (adjacent peach trees directly sprayed) and direct spray (buckwheat and peaches directly sprayed). Drift‐treated buckwheat received about 1.4% the amount of thiamethoxam as direct‐spray buckwheat. This amount has no lethal effects on parasitoids,

Sanitation felling against the European spruce bark beetle: A matter of intensity and forest type Tagli fitosanitari contro il bostrico tipografo: una questione di intensità e tipologia forestale

Agricultural and Forest Entomology, EarlyView.
We assess the effect of sanitation felling performed in 2022 in North‐Eastern Italy on bark beetle damage that occurred in 2023 across eight spruce forest types, as evaluated using multispectral satellite imagery. Bark beetle damage was reduced only at very high or very low sanitation felling rates.

How a Traveling Exhibition on Wasps Altered Public Perceptions

Curator: The Museum Journal, EarlyView.
ABSTRACT Media portrays a caricature of the “evil” wasp (a flying insect), perpetuating fears developed at a young age or from individual negative experiences. Because wasps are critically important to nature and our agriculture, it is important to provide some form of education to lessen this fear.

Plant Domestication Affects the Oviposition Behavior and Performance of Ganaspis kimorum, a Parasitoid of Drosophila suzukii

Entomologia Experimentalis et Applicata, EarlyView.
In this study, we investigated the effects of blueberry domestication on the oviposition behavior and performance of Ganaspis kimorum, a parasitoid of Drosophila suzukii. Domestication of blueberries reduced the oviposition‐searching behavior of the parasitoid but enhanced parasitoid performance, including offspring performance. Additionally, blueberry

A New Experimental Setup to Study the Olfactory Behaviour of Trichogramma Egg Parasitoids

Entomologia Experimentalis et Applicata, EarlyView.
We developed an experimental setup to assess odor‐induced egg‐laying behavior in tiny egg‐parasitoid wasps. This Y‐shaped olfactometer, coupled with an AI‐based image‐recognition model, automatically quantifies egg parasitism by Trichogramma wasps. Olfactory‐driven egg‐laying preferences were analyzed using Bayesian inference.

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 ...

Aliens vs. paper wasps: new records of Darwin wasps parasitizing social wasps in Brazil

Revista de la Sociedad Entomológica Argentina
This study reports new associations between Ichneumonidae and social wasps, contributing to the under-standing of the ecological relationships between species and expanding current knowledge of their geo-graphic distribution. We identified a total of five Ichneumonidae species associated with colonies of five species of social wasps.

Multiparasitism Resolves the Apparent Paradox of High Male Pheromone Investment Despite Frequent Within‐Host Mating in a Parasitoid

Entomologia Experimentalis et Applicata, EarlyView.
It is unknown why males of the parasitoid wasp Nasonia giraulti produce large amounts of a costly sex pheromone although they were long thought to mate with their females already before emergence within the host. Mated females do no longer respond to the pheromone.

HST SHEL: Enabling Comparative Exoplanetology with HST/STIS

The Astronomical Journal
The Hubble Space Telescope (HST) has been our most prolific tool to study exoplanet atmospheres. As the age of JWST begins, there are a wealth of HST archival data that are useful to strengthen our inferences from JWST.

Cost of parasite exposure depends on host ontogeny 寄生接觸的代價依賴於宿主發育階段

Ecological Entomology, EarlyView.
The cost of parasite exposure varies across host developmental stages, demonstrating that ontogeny influences the expression of non‐consumptive effects (NCEs). Mite exposure resulted in consumptive effects in fly eggs and NCEs in early‐stage pupae; mite longevity was comparable when provisioned with pupae or water but increased when provisioned with ...
