Fraxinus foliage: does host species during adult maturation feeding alter the fecundity of emerald ash borers, Agrilus planipennis Fairmaire (Coleoptera: Buprestidae)?

Environmental Entomology, Journal Year: 2025, Volume and Issue: unknown

Abstract Herbivorous insects can have their reproductive potential influenced by the quality and species of host plants they feed upon. The emerald ash borer (EAB), Agrilus planipennis Fairmaire (Coleoptera: Buprestidae), is an invasive pest trees (Fraxinus spp.) within its introduced range. As adults, EAB must upon foliage to sexually mature. We compared influence 4 North American on via feeding assess impacts female lifespan metrics. fed 136 EAB, 34 in each group, either black, green, tropical, or white throughout adult life. performed daily inspections for mortality, oviposition, egg hatching. found that mean lifespan, fertility rate, development time were not affected species. Potential realized fecundity increased with summed group (days), but this rate differed among Consequently, there was a statistically significant interaction effect foliage.

Effects of flood duration on seedling survival and growth of potential replacement species in black ash (Fraxinus nigra Marshall) forests threatened by emerald ash borer

Trees Forests and People, Journal Year: 2023, Volume and Issue: 11, P. 100367 - 100367

Within black ash (Fraxinus nigra Marshall) wetlands, acts as a foundational species, resulting in high vulnerability to the invasive emerald borer (EAB) (Agrilus planipennis Fairmaire) (Coleoptera: Buprestidae). One mitigation strategy being considered is planting of alternative tree species increase compositional diversity, however, there limited understanding how replacement tolerate flooding. A greenhouse experiment was used explore early survival and growth eighteen response five flooding durations (3, 6, 9, 12, or 15 weeks). Seedlings were assigned flood tolerance groups according their responses various duration treatments. Taxodium distichum (L.) Rich., Ulmus americana L., Betula L. able survive grow with up weeks. Thuja occidentalis Acer rubrum Larix laricina (Du Roi) K. Koch, Quercus bicolor Willd., alleghaniensis Britton had rates 6 weeks length. Finally, Juglans saccharum Marshall responded poorly any duration. These results can assist managers matching potential hydrology local wetlands.

Biocultural Importance of the Chiuri Tree [Diploknema butyracea (Roxb.) H. J. Lam] for the Chepang Communities of Central Nepal

Major socio-economic changes over the last few decades have reduced Indigenous peoples’ engagement in cultural practices, such as harvesting of forest resources. Nevertheless, some species remain important for culture, subsistence and livelihood, chiuri tree (Diploknema butyracea (Roxb.) H. J. Lam) to Chepang people Central Nepal. Using keystone framework, we conducted interviews within communities assess biocultural importance tree. It is central no other could provide same benefits. also provides food habitat a number wildlife species, including bats, which are themselves culturally important. Strictly observed ownership rules, well ban on cutting branch lopping, so far contributed conservation. However, these rules increasingly less adhered to.

Species Preservation in the Face of Novel Threats: Cultural, Ecological, and Operational Considerations for Preserving Tree Species in the Context of Non-Indigenous Insects and Pathogens

Journal of Forestry, Journal Year: 2023, Volume and Issue: 121(5-6), P. 470 - 479

Published: June 26, 2023

Abstract Non-Indigenous insects and pathogens (NIIP) have functionally eliminated numerous tree species of immeasurable cultural ecological significance over the past century, with number introductions associated impacts growing each year. Foresters are often on frontlines these impacts, tasked quickly adapting management plans to recover potential economic losses maintain future silvicultural options following loss. We highlight that irreplaceable values provided by many argues for renewed focus applying integrated pest adaptive strategies in novel ways sustain generations. To guide efforts, we describe a framework NIIP centered three interrelated components: preservation value, approach, strategy. This emerging efforts provide an alternative path forward threatened their era increasing change. Study Implications: The impact non-indigenous is one greatest challenges facing long-term stewardship forests North America. Species apply face increasingly needed foresters’ toolboxes address threats. Identifying (ethical responsibility, integrity, function, genetic conservation) tied effort will help how approaches applied at stand landscape scales into future.

Physical and mechanical properties affecting the suitability of black ash wood for W8banaki basketry

Canadian Journal of Forest Research, Journal Year: 2024, Volume and Issue: 54(10), P. 1170 - 1182

Published: June 21, 2024

Black ash ( Fraxinus nigra Marsh.) is an important species for the W8banaki Nation, which uses its wood traditional basketry. This study aimed to identify properties required black splints used in Eleven logs were selected and pounded into 26 longitudinal groups of annual layers, then transformed splints. A quality class (high, medium, or low) was assigned by W8banakiak knowledge carriers each group rings. We measured density, ring width, modulus elasticity, rupture on samples located at same radial position bolts collected adjacently pounding. To investigate best related class, we applied a generalized linear mixed model. Our model revealed significant effect width average density probability obtain given class. Narrow- medium-sized rings relatively dense offered basketry practice. Based our results, further research effects growth conditions that favour production high-quality could be conducted ultimately propose silvicultural treatments management strategies.
