2016 journal article

Comparison of two detailed models of Aedes aegypti population dynamics

Ecosphere, 7(10), e01515.

author keywords: Aedes aegypti; model comparison; mosquito-borne diseases; population dynamics; spatial model; vector control
TL;DR: It is shown that predictions of population recovery by the models differ substantially, an effect likely related to model assumptions regarding larval development and (direct or delayed) density dependence, and revealing the impact of model assumptions on population dynamics predictions in unperturbed and perturbed conditions.

Gene-drive into insect populations with age and spatial structure: a theoretical assessment

Evolutionary Applications, 4(3), 415–428.

By: Y. Huang n, A. Lloyd n, M. Legros n & F. Gould n

author keywords: age and spatial structure; engineered underdominance; gene drive; release threshold; theoretical assessment
TL;DR: This study demonstrates that to determine the best method of spatial release, and the total number of engineered insects that must be released, it is important to take into account the age and sex of the released insects and spatial structure of the population. (via Semantic Scholar)

Insect oviposition behavior affects the evolution of adaptation to Bt crops: consequences for refuge policies

EVOLUTIONARY ECOLOGY, 24(5), 1017–1030.

By: M. Jongsma*, F. Gould n, M. Legros n, L. Yang*, J. Loon* & M. Dicke*

author keywords: Behavioral resistance; Physiological resistance; Bt crop; Monitoring; Host specificity; Host shift
TL;DR: It is demonstrated that certain ecological conditions allow for the evolution of behavioral choices favoring alternative oviposition hosts that limit the increase in resistance alleles, even when they are phenotypically dominant. (via Semantic Scholar)
