Spatial and temporal dynamics of soybean gall midge (Resseliella maxima) parasitism by Synopeas maximum

Pest Management Science, Volume 79, Issue 12, Page 5096-5105, December 2023., 2023
We confirmed parasitism of Resseliella maxima by Synopeas maximum and used our combinatorial approach to observe the spatial and temporal relationships between R. maxima and its parasitoid in the field. Abstract BACKGROUND Soybean gall midge, Resseliella maxima Gagné (Diptera: Cecidomyiidae), is a pest that impacts soybean yield in the Midwest United ...

Old and new association of Cotesia icipe (Hymenoptera: Braconidae) with alien invasive and native Spodoptera species and key stemborer species: implication for their management

Pest Management Science, Volume 79, Issue 12, Page 5312-5320, December 2023., 2023
Cotesia icipe parasitized and successfully developed in fall armyworm, Spodoptera littoralis and stemborers. The parasitoid preferred Spodoptera spp. to stemborers, and the highest fitness of progenies was recorded from Spodoptera spp. Abstract BACKGROUND Maize production in Africa is hindered by a myriad of biotic challenges, key among them being ...

Microhymenoptera in roadside verges and the potential of arthropod‐friendly mowing for their preservation

Journal of Applied Entomology, Volume 147, Issue 10, Page 1035-1044, December 2023., 2023
Abstract The worldwide decline of insects is one of the major challenges for humankind. One of its main drivers is intensive farming, which reduces habitats and food resources for insect populations and causes direct mortality by pesticides. In addition, mowing of grassland poses another threat to insects, especially when it is done frequently, such as

Sown wildflowers between vines increase beneficial insect abundance and richness in a British vineyard

Agricultural and Forest Entomology, Volume 25, Issue 1, Page 139-151, February 2023., 2023
Abstract Traditional vineyards are generally intensive monocultures with high pesticide usage. Viticulture is one of the fastest‐growing sectors of English agriculture, although there is currently limited research on habitat management practices. In a vineyard in East Sussex, England, we tested five inter‐row ground cover treatments on their potential ...

A curated DNA barcode reference library for parasitoids of northern European cyclically outbreaking geometrid moths

Ecology and Evolution, Volume 12, Issue 11, November 2022., 2022
We present a curated DNA barcode database for all parasitoid species associated with two geometrid species (Epirrita autumnata and Operophtera brumata) undergoing cyclic population outbreaks in the subarctic mountain birch forests that form the treeline in northern Europe.

Rainforest conversion to cash crops reduces abundance, biomass and species richness of parasitoid wasps in Sumatra, Indonesia

Agricultural and Forest Entomology, Volume 24, Issue 4, Page 506-515, November 2022., 2022
Abstract Parasitoid wasps affect herbivory in natural and agricultural ecosystems, including cash crops. The impacts of rainforest transformation to rubber and oil palm on parasitoid wasp communities are poorly understood. We collected canopy arthropods, once each in dry season and rainy season, via canopy fogging in four land‐use systems in Jambi ...
