Bionomics of Autogenous Mosquitoes Andrew Spielman

Bionomics of Autogenous Mosquitoes Andrew Spielman Presented by Anthony Clemons 1st Year Grad Student

Keywords Defined Bionomics comprehensive study of an organism and its relationship to its environment Autogeny egg production through

facultative blood-feeding Facultative - BF when conditions permit Anautogeny - egg production through obligate blood feeding Obligate BF is necessary for egg production

Fecundity the ability to reproduce Diapause delay in development in response to regulatory or adverse environmental conditions Corpora allata endocrine gland which

generates juvenile hormone Juvenile hormone promotes larval development and inhibits metamorphosis Corpora cardiaca function in the storage and secretion of brain hormones i.e.

neurosecretory hormone Focus of Article To bring together some of the literature that has characterized facultative blood-feeding

Autogeny vs Anautogeny Autogenous mosquito can lay one clutch of eggs before the requirement of a

blood-meal (BM) for subsequent egg lays Absence of diapause, the arrest of ovary development Small clutch size (nonBM egg lay)

Anautogenous mosquito require 1 or in some cases 2 (super-anautogeny) BM before they are

able to lay eggs Diapause Large clutch size Contributing Factors Genetics

Nutrition (Possible link to genetics) Environment Genetics Chromosome III carries information that regulates autogeny

Chromosome I carries genetic information that modifies the penetrance of genetic information from Chromosome III Quantitative trait loci determine autogeny and body size in Asian tiger mosquito (Aedes albopictus) A. Mori et. al. Heredity 2008

Nutrition Autogenous mosquitoes amass much greater stores of fat during larval life To induce yoke deposition in ovaries of

anautogenous females researchers 1) transplatated corpora allata, 2) Transfused hemolymph, 3) Placement of eggs developed after betaecdysone into hemolymph of female A. aegypti,

And, 4) Abdomen ligation Environmental Factors Temporal, spatial and behavioral barriers due to location play a role in the distribution of antogenous vs anautogenous mosquitoes
