Journal of Bioresource Management

Forest cockroaches are among the insects that play an important and effective role in forest formations, they are insects with incomplete metamorphosis belonging to the order of Blattodea. This work is a contribution to the knowledge of Blattoptera species existing in the forest environments of Aflou’s region (Laghouat; Algeria).The inventory was carried out monthly in the El-Khnegue Forest (Aflou) from February 2019 to May 2019. It revealed the presence of six species of forest Cockroaches, which belongs to 4 genera of the Blattelidae family. After identification, it was demonstrated that, these species were: Dziriblatta nigriventris (Chopard, 1936), Dziriblatta stenoptera (Chopard, …

Conservation And Variation In Agricultural Landscapes: A Survey Of Insect Populations Across Naranjilla Cultivation Methods In The Eastern Andean Cloud Forest, Ian Zakelj

Independent Study Project (ISP) Collection

This study compared insect biodiversity among five sites in agricultural landscapes and natural forest in the El Placer community in the valley of the Rio Pastaza in the eastern Andean cloud forest. The area is of vital importance to conservation, as it falls in the ecological corridor between the Sangay and Llanganates national parks. The primary crop produced by the residents of El Placer is naranjilla, and it is cultivated in a variety of manners, mostly with intensive chemical use. The goal of the study was to find out which types of practices were the least harmful to the insect …

Mark-Recapture Study And Habitat Assessment For The Northern Metalmark Butterfly, Calephelis Borealis (Lepidoptera: Riodinidae), Weston J. Henry, Kristian S. Omland, Henry Frye, Wagner L. David

EEB Articles

Background: The northern metalmark (Calephelis borealis), is an exceedingly local, globally rare butterfly that is declining across the Midwestern and Northeastern USA. The principal stressors driving colony losses include afforestation and invasive plants that crowd out its larval hostplant (Packera ovata) and nectar resources.

Aims/Methods: To better understand its declines and guide restoration efforts, we 1) performed a mark-recapture study in Connecticut to document population trends where we were actively managing vegetation; 2) conducted a range-wide survey for evidence of phylogeographic structure, using cytochrome oxidase (CO1); 3) investigated abundance determinants of its larval foodplant, Packera ovata …

Abundant, Distinct, And Seasonally Dynamic Bee Community In The Canopy-Aerosphere Interface Above A Temperate Forest: Associated Data, Michael J. Cunningham-Minnick, Joan Milam, Brian Kane, H. Patrick Roberts, David I. King

Data and Datasets

This dataset describes bees (Apoidea) sampled with blue vane traps at different heights within and above a temperate forest on the campus of University of Massachusetts Amherst from April through August of 2021, as well as the R-code used for data analyses. Specifically, it includes 2 files: 1) all data on individual specimens, including species identifications, occurrence dates and coordinates, and more information on encounter location and study design, and 2) All code used to generate figures and tables from the data that are included within the published manuscript.

Invasive Plants Watch List: 2022, Allison Zach

Nebraska Invasive Species Program

The purpose of the weed watch list is to collect data on the distribution of invasive plants found in various Nebraska counties. Counties were divided up into ‘ecoregions’ based on the Nebraska Game & Parks Commission’s Legacy Plan (map of regions below). The plants in the watch list have been identified based on their invasiveness in surrounding states and their increasing range in Nebraska. Data collected on watch list plant species distribution has been used to support the listing or delisting of noxious weeds. Plant species in the weed watch list are categorized based on early detection and rapid response …

Rna Interference For Emerald Ash Borer Suppression: Ecotoxicological Assessment And Delivery Methods, Flavia Pampolini

Theses and Dissertations--Entomology

The emerald ash borer (EAB), Agrilus planipennis (Coleoptera: Buprestidae), is a highly invasive phloem-feeding insect native to Asia. It has killed millions of ash trees (Fraxinus spp.) since its accidental introduction into North America, causing profound economic and ecological impacts. RNA interference (RNAi) or double-stranded RNA (dsRNA)-mediated gene silencing is an emerging biotechnology that is developing as an innovative tool for pest management. Exogenous dsRNA triggers the RNAi pathway, silences genes, and disrupts protein function, causing insect mortality. RNAi has proven effective in reducing target gene expression and causing mortality in EAB; however, two aspects stand as barriers …
