Y-Autosome Genetic Sexing Strain of Anopheles albimanus (Diptera: Culicidae)

  • Titus K. Mukiama


Stripe (st+) is a dominant trait on chromosome 3R in region 33B on the cytological chromosome map of Anopheles albimanus. It is expressed as a white longitudinal stripe in fourth stage larvae and pupae, and marks a Y-autosome translocation stock T(Y; 3R)3. Pseudolinkage analysis of the available markers to the translocation breakpoint showed complete absence of recombinant progeny between T(Y;3R)3 and st+. The two loci most likely either overlap or are very closely linked. This translocation strain can be genetically sexed by selection of the stripe marker.

Stripe (st+) est un caractère dominant localise sur le chromosome 3R de la region 33B de la carte chromosomique de Anopheles albimanus. Ce caractère s’exprime comme une bande blanche longitudinale dans les larves et pupae du/quatrième étage et correspond a une souche T(Y;3R)3 caractérisée par une translocation Y-autosomique. Une analyse pseudoliaison entre les marqueurs disponibles et le point de rupture de la translocation a montre une absence complete de descendance recombinante entre T(Y; 3R)3et st+. Les deux loci sont probablement superposes ou lier très étroitement. Le sexe de la souche transloquée/peut être determine génétiquement par selection du marqueur stripe.
