There are so many parasitoids, ranging from a few mm to several cm... buuut they're so hard to identify. This is an easy one though: Ischnus inquisitorius, a woodland species that occurs across the Northern Hemisphere and parasitizes tortricid moths. It has white rings around its eyes.

Our new paper led by Christian Weinrich (PhD student, Andrew Forbes' lab at University of Iowa) is out in Insect Systematics and Diversity. We used unsupervised machine learning + UCE data to infer species limits in eurytomid parasitoids on US oak gall wasps—all initially thought to be Eurytoma.

As of this morning, Kyiv casualties from Russia's 24 May strike rose to 87 wounded, including three minors. Rescuers extracted two women's bodies from a five-story residential building, per the Emergency Service. 📹 DSNS

Our new paper, led by Dr. Yurii Geryak, reports the first occurrence of the invasive pest moth Spodoptera frugiperda in Ukraine and Eastern Europe, with the earliest confirmed record dating back to June 2021. Thank you @integsyst.bsky.social @dwhitmore79.bsky.social #lepidoptera #moth #invasion

I am happy to be a part of the 2nd International Electronic Conference on Entomology organized by Insects, MDPI. Please check out our presentation here: Abstract: sciforum.net/paper/view/2... Poster: sciforum.net/manuscripts/...

Poster presented on the 2nd International Electronic Conference on Entomology. Title “Potential Invasion and Distribution of Lymantria mathura in Ukraine: Risk Assessment and Management Strategies”, authors
KLECHKOVSKIY, TITOVA, BONDAREVA and KALIUZHNA (Ukraine).
Lymantria mathura (Moore, 1865), the rosy gypsy moth, is a polyphagous defoliator from the family Erebidae, which inhabits deciduous forests mainly in South and Southeast Asia. The broad trophic spectrum of this species makes it an important pest that threatens forests, urban greenery, ornamental plants, and fruit trees. Due to climate change, this species could become a threat beyond its natural range and the aim of our research was to assess the risk of invasion and establishment of L. mathura in Ukraine and to model the potential distribution of natural enemies of this moth.
GIS modeling in MapInfo Pro 15.0 and IDRISI Selva was used to model the potential distribution of L. mathura, and MaxEnt was used to model the potential distribution of entomophagous insects known to be effective in L. mathura biocontrol.
We found that the potential range of L. mathura covers almost all of Ukraine, except for the Carpathian highlands. The most important bioclimatic factors influencing its establishment are the mean annual temperature, the temperature of the warmest month, and the sum of active temperatures above 10 ℃, while the limiting factor is the mean temperature of the coldest month. Modeling suggests that natural enemies such as Cotesia melanoscela (Hymenoptera: Braconidae), Compsilura concinnata, and Carcelia gnava (Diptera: Tachinidae) could play a crucial role in biological control if L. mathura invades Ukraine.
Due to its high risk of introduction, broad climatic tolerance, excellent flight ability, and numerous suitable host plants, L. mathura poses a serious threat to Ukraine's plant resources. A key risk management strategy could be its inclusion in List A1 (absent) of the Ukrainian Regulated Pests List.

What can happen to a book if nobody reads it - actual bookworms 🐛🪱 Today we've been called to check the situation with books and other artifacts damage from insects in local library. Lower number of readers could be a serious challenge to a library, especially for the old books. #insects #library
