Analysis of inheritance of oral susceptibility of Aedes aegypti (Diptera: Culicidae) to dengue-2 virus using isofemale lines.

Isofemale lines were compared to determine possible genetic variation in oral susceptibility within the Fare strain of Aedes aegypti (L.) to dengue-2 (DEN-2) virus. Three groups of 12 isofemale lines each were tested statistically using the SAS CATMOD procedure of analysis of variance. The "isofemale line" effect was highly significant, demonstrating genetic variability in oral susceptibility among females. The length of time eggs were stored before hatching influenced the oral susceptibility of the adult mosquitoes for DEN-2 review.
