Quantitative trait loci determining autogeny and body size in the Asian tiger mosquito (Aedes albopictus).

ABSTRACT: The majority of mosquito species require a blood meal to stimulate vitellogenesis and subsequent oviposition (anautogeny), but some autogenous individuals complete their first ovarian cycle without a blood meal. Autogeny may be facultative or obligatory. In this study, we selected for an autogenous strain in the Asian tiger mosquito Aedes albopictus and examined an F(1) intercross population for quantitative trait loci (QTL) determining the autogeny trait as well as wing length as a proxy for body size. Using composite interval mapping, we identified four QTL for each trait and observed considerable overlap in genome positions between each QTL for autogeny (follicle size) and wing length. Most QTL were minor in magnitude, individually explaining <10% of the phenotypic variation. Alleles fr
