Abstract Trap colour can be an important consideration in detection programmes for arboreal and saproxylic beetles. Green purple intercept traps are more attractive than black to the emerald ash borer, Agrilus planipennis Fairmaire (Coleoptera: Buprestidae), invasive species North America. In four experiments, I tested three commercial multiple-funnel (green, purple, black), baited with various lure blends, determine relative effects of trap on catches other bark woodboring beetles, their associated predator species, north–central Georgia, United States captured numerous Cerambycidae (Coleoptera) ( n = 51), Curculionidae 33), predators 22) across experiments. However, majority were either unaffected by or caught greater numbers green traps. The two exceptions Enoclerus ichneumonus (Fabricius) Cleridae) Pycnomerus sulcicollis LeConte Zopheridae), which abundant Purple performed better following species: Cnestus mutilatus (Blandford) Curculionidae), Cossonus corticola Say Xylobiops basilaris (Say) Bostrichidae), Buprestis lineata Fabricius Namunaria guttulata (LeConte) Zopheridae).

Distinct metabolites affect the phloem fungal communities in ash trees (Fraxinus spp.) native and nonnative to the highly invasive emerald ash borer (AGRILUS PLANIPENNIS)

Plant Cell & Environment, Journal Year: 2024, Volume and Issue: 47(11), P. 4116 - 4134

Published: June 23, 2024

Emerald ash borer (EAB, Agrilus planipennis) is an invasive killer of trees (Fraxinus spp.) in North America and Europe. Ash species co-evolved with EAB their native range Asia are mostly resistant, although the precise mechanism(s) remain unclear. Very little also known about or tree microbiomes. We performed first joint comparison phloem mycobiome metabolites between a nonnative species, infested uninfested EAB, conjunction investigation larval mycobiome. Phloem communities differed but both were unaffected by infestation. Several indicator taxa gut shared similarly high relative abundance only host trees. Widely targeted metabolomics revealed 24 distinct 53 trees, respectively, that content one species. Interestingly, four strong relationship mycobiomes, majority which affected Collectively, our results demonstrate complex interplay chemistry mycobiome, suggest relationships mycobiomes may reflect co-evolution.

Understanding the evolutionary processes underlying range-wide genomic variation is critical to designing effective conservation and restoration strategies. Evaluating influence of connectivity, demographic change environmental adaptation for threatened species can be invaluable proactive potential. In this study, we assessed across range Fraxinus latifolia, a foundational riparian tree native western North America recently exposed invasive emerald ash borer (Agrilus planipennis; EAB). Over 1000 individuals from 61 populations were sequenced using reduced representation (ddRAD-seq) species' range. Strong population structure was evident along latitudinal gradient, with connectivity largely maintained central valley river systems, centre genetic diversity coinciding major systems Despite evidence estimates nucleotide size low all populations, suggesting patchy distribution F. latifolia may impact its long-term Range-wide offset, which indicate required adjust future climate projections, greatest in eastern lowest southern portions range, regional potential longer-term. To preserve capacity needed development breeding programmes, prioritising will provide foundation management.

RNA interference (RNAi) is a sequence-specific gene silencing mechanism triggered by double-stranded (dsRNA). Exploiting the RNAi to silence essential genes in insects has emerged as promising new pest control strategy, and RNAi-based products are being developed for plant protection. proven effective causing mortality highly invasive emerald ash borer (EAB) (Agrilus planipennis) (Coleoptera: Buprestidae); however, practical delivery method remains barrier its deployment.

Parallels and discrepancies between non‐native species introductions and human migration

Published: Feb. 20, 2025

Biological invasions and human migrations have increased globally due to socio-economic drivers environmental factors that enhanced cultural, economic, geographic connectivity. Both processes involve the movement, establishment, spread of species, yet unfold within fundamentally different philosophical, social biological contexts. Hence, studying (invasion science) migration (migration studies) presents complex parallels are potentially fruitful explore. Here, we examined nuanced differences between these two phenomena, integrating historical, socio-political, ethical perspectives. Our review underscores need for context-specific approaches in policymaking governance address effectively challenges opportunities harm from invasions. We suggest provide an excellent opportunity transdisciplinary research; one acknowledges complexities potential insights both fields study. Ultimately, natural sciences offers a promising avenue enriching understanding invasion biology dynamics while pursuing just, equitable, sustainable solutions. However, is clear driver invasions, drawing on principles understand past current risks oversimplification harmful generalisations disregard intrinsic rights cultural migrations. By doing so, frameworks support development policies respect dignity, foster diversity, ways promote global cooperation justice.
