author keywords: Bt resistance; bollworm; crop intensity; Helicoverpa zea; risk assessment
MeSH headings : Animals; Bacillus thuringiensis / genetics; Bacterial Proteins / genetics; Endotoxins; Gossypium; Hemolysin Proteins / genetics; Insecticide Resistance; Moths / genetics; Plants, Genetically Modified / genetics; Zea mays / genetics
TL;DR: Landscape-level predictors of H. zea damage in Bt cotton can be used to identify heightened Bt resistance risk areas and serves as a model to understand factors that drive pest resistance evolution to Bt toxins in the southeastern United States. (via Semantic Scholar)

Soybeans as a non-Bt refuge for Helicoverpa zea in maize-cotton agroecosystems

Agriculture, Ecosystems & Environment, 322, 107642.

By: S. Dorman n, K. Hopperstad n, B. Reich n , G. Kennedy n  & A. Huseth n 

author keywords: Bollworm; Bt-refuge; Resistance management; Risk description; Row crops
TL;DR: Soybeans in North Carolina and southeastern U.S. likely serves as a critical non-Bt refuge for delaying H. zea resistance to Bt toxins in landscapes dominated by Bt maize and cotton, and inverse distance weighted (IDW) soybeans is the most important predictor of H.Zea abundance through time in row crop agroecosystems inNorth Carolina.

Estimations of Fine-Scale Species Distributions of Aedes aegypti and Aedes albopictus (Diptera: Culicidae) in Eastern Florida

JOURNAL OF MEDICAL ENTOMOLOGY, 58(2), 699–707.

By: K. Hopperstad n, M. Sallam * & M. Reiskind n 

Ed(s): G. Hamer

author keywords: habitat suitability model; maximum entropy model; MaxEnt; Aedes aegypti; Aedes albopictus
MeSH headings : Aedes; Animal Distribution; Animals; Ecosystem; Florida; Models, Statistical; Mosquito Control; Species Specificity; Temperature
TL;DR: Fine-scale empirical models like those presented here have the potential for precise risk assessment and the improvement of operational applications to control container-breeding Aedes mosquitoes. (via Semantic Scholar)

Sunshine versus gold: The effect of population age on genetic structure of an invasive mosquito

ECOLOGY AND EVOLUTION, 10(18), 9588–9599.

By: E. Pless *, K. Hopperstad n, N. Ledesma *, D. Dixon*, J. Henke & J. Powell *

author keywords: Aedes aegypti; age of population; invasive species; mosquitoes; population genetics; population structure
TL;DR: Comparing likely the oldest populations of Aedes aegypti in continental North America with some of the newest to illuminate the range of genetic diversity and structure that can be found within the invasive range of this important disease vector shows that the older populations have dramatically higher genetic Diversity and lower genetic structure.

Simplification of vector communities during suburban succession

PLOS ONE, 14(5), e0215485.

By: M. Spence Beaulieu n , K. Hopperstad n, R. Dunn n  & M. Reiskind n 

Ed(s): P. Leisnham

MeSH headings : Aedes / classification; Animals; Demography; Disease Vectors / classification; Housing / statistics & numerical data; Humans; Mosquito Vectors / classification; North Carolina; Social Class; Suburban Population
TL;DR: It is demonstrated that suburbanization is disrupting mosquito communities so severely that they do not recover their diversity even 100 years after the initial disturbance, which is significant for vector-borne disease transmission in highly suburbanized areas. (via Semantic Scholar)

author keywords: Aedes albopictus; Culex quinquefasciatus; Zika; dispersal; sampling
MeSH headings : Aedes; Animals; Culex; Environment; Environmental Monitoring; Larva; North Carolina; Pupa
TL;DR: Gas stations may be a convenient surveillance target for vector control specialists and may provide insight into human-aided mosquito dispersal. (via Semantic Scholar)

Mosquitoes of field and forest: the scale of habitat segregation in a diverse mosquito assemblage

Medical and Veterinary Entomology, 31(1), 44–54.

By: M. Reiskind n , R. Griffin*, M. Janairo n & K. Hopperstad n

author keywords: Disease ecology; habitat edges; landscape ecology; vector-borne pathogens
MeSH headings : Animal Distribution; Animals; Biodiversity; Culicidae / physiology; Ecosystem; Forests; Grassland; North Carolina; Population Density
TL;DR: The present results suggest blood‐seeking mosquito species are faithful to certain habitats, which has consequences for patterns of vector diversity and risk for pathogen transmission, and developers of land management strategies should assess habitat at a finer scale than previously considered.
