Development of the first high-density linkage map in the maize weevil, Sitophilus zeamais

PEERJ, 11.

By: J. Baltzegar n & F. Gould n 

author keywords: Maize weevil; Linkage map; Sitophilus; ddRadSeq; Agricultural pest
TL;DR: The genome size was measured and the first genetic linkage map for this species was developed, which contains 11 linkage groups, which correspond to the 10 autosomes and 1 X-chromosome found in the species and it contains 1,121 SNPs. (via Semantic Scholar)

2023 journal article

Population genetic structure of the maize weevil, Sitophilus zeamais, in southern Mexico

PLOS ONE, 18(4).

By: J. Baltzegar n, M. Jones n, M. Willcox *, J. Ramsey * & F. Gould n 

MeSH headings : Animals; Humans; Weevils / genetics; Mexico; Agriculture; Genetic Drift; Genetic Structures; Zea mays / genetics
TL;DR: It is shown that although there continues to be gene flow between populations of maize weevil, that fine-scale genetic structure exists and is shaped by the movement and trade of maize by humans in the region, by geographic barriers to gene flow, or a combination of factors.

Rapid evolution of knockdown resistance haplotypes in response to pyrethroid selection in Aedes aegypti

Baltzegar, J., Vella, M., Gunning, C., Vasquez, G., Astete, H., Stell, F., … Gould, F. (2021, July 9). EVOLUTIONARY APPLICATIONS, Vol. 7.

By: J. Baltzegar n, M. Vella n, C. Gunning*, G. Vasquez*, H. Astete *, F. Stell*, M. Fisher*, T. Scott * ...

author keywords: Aedes aegypti; dominance; insecticide resistance; kdr; knockdown resistance; selection
TL;DR: This study describes the evolution of knockdown resistance (kdr) haplotypes in Aedes aegypti in response to pyrethroid insecticide use over the course of 18 years in Iquitos, Peru, providing evidence for the direct connection between programmatic citywidepyrethroid spraying and the increase in frequency of specific kdr haplotypes.

2016 journal article

Application of a dense genetic map for assessment of genomic responses to selection and inbreeding in Heliothis virescens

INSECT MOLECULAR BIOLOGY, 25(4), 385–400.

By: M. Fritz n, S. Paa n, J. Baltzegar n & F. Gould n 

author keywords: Heliothis virescens; genetic variation; colonization; inbreeding; ddRAD-seq; linkage map
MeSH headings : Animals; Bacillus thuringiensis / physiology; Bacillus thuringiensis Toxins; Bacterial Proteins / pharmacology; Chromosome Mapping; Endotoxins / pharmacology; Female; Genetic Variation; Genome, Insect; Hemolysin Proteins / pharmacology; Insecticide Resistance; Insecticides / pharmacology; Male; Moths / genetics
TL;DR: It is found that allelic and nucleotide diversity declined dramatically in laboratory-reared H. virescens as compared with field-collected populations, and the general expectations for reduced genetic diversity in laboratory colonies are confirmed. (via Semantic Scholar)
