Winners and losers in subarctic moth communities in a changing climate: Marine regime shifts as predictors for terrestrial insect biomass

open access: yesInsect Conservation and Diversity, EarlyView.
1972–2017, the total moth biomass ina subarctic community had a positive trend but biomass trends differ betweenmoth groups based on taxonomy, phenology and resource use. In the northern latitudes,outbreaking species impact greatly moth biomass Moth biomass is associated withtemperature variables and marine Regime shifts, which can be effective ...

Sawfly Control, 1994 [PDF]

open access: yesArthropod Management Tests, 1995
Abstract Materials were applied on 8 Jun for mid- to late instar BS control to 20- by 20-ft plots in a bearing blueberry field at Columbia, Maine. There were 2 replications of each treatment in a CRD with a minimum 5-ft untreated buffer strip around each plot.

Sawfly egg deposition extends the insect life cycle and alters hormone and volatile emission profiles

open access: yesFrontiers in Ecology and Evolution, 2023
IntroductionInsect oviposition can enhance plant defenses and decrease plant quality in response to future feeding damage by hatched larvae. Induced resistance triggered by egg deposition and its negative effect on insect herbivore performance is known ...

Biological Pesticides as Viable Alternative to Synthetic Pesticides for Sustainable Agriculture and Nutrition: A Systematic Review

open access: yesJournal of Sustainable Agriculture and Environment, Volume 5, Issue 2, June 2026.
ABSTRACT The overuse of synthetic pesticides in agriculture has raised significant environmental and health concerns. Biopesticides have emerged as viable, environmentally compatible alternatives. However, recent comprehensive reviews integrating all biopesticide categories and emphasizing their contribution to synthetic‐pesticide‐free and health‐safe ...

Sawfly genomes reveal evolutionary acquisitions that fostered the mega-radiation of parasitoid and eusocial Hymenoptera

open access: yes, 2020
The tremendous diversity of Hymenoptera is commonly attributed to the evolution of parasitoidism in the last common ancestor of parasitoid sawflies (Orussidae) and wasp-waisted Hymenoptera (Apocrita).

Dolerus asper Zaddach, 1859 and Dolerus brevicornis Zaddach, 1859 (Hymenoptera: Tenthredinidae), with notes on their phylogeny

open access: yesEuropean Journal of Entomology, 2004
Concordant differences in morphology, phenology and RAMS markers, as well as in sequenced mtDNA (COI, COII, cytb) and nuclear DNA (ITS2) fragments, indicate that Dolerus asper Zaddach, 1859 and Dolerus brevicornis Zaddach, 1859 are valid species.

Genome and transcriptome‐based identification and expression profiling of chemosensory gene families across developmental stages and tissues in Sirex noctilio (Hymenoptera: Siricidae)

open access: yesInsect Molecular Biology, Volume 35, Issue 3, Page 270-283, June 2026.
The first draft genome of Sirex noctilio was produced. Fifteen S. noctilio transcriptomes were sequenced to study chemosensory gene expression patterns. SnocOR16 and SnocSNMP1 displayed tissue‐ and sex‐specific expression patterns. Abstract The Sirex woodwasp (Sirex noctilio; Hymenoptera: Siricidae) is among the most destructive invasive pests ...
