The gene transformer-2 of Anastrepha fruit flies (Diptera, Tephritidae) and its evolution in insects
Background In the tephritids Ceratitis, Bactrocera and Anastrepha, the gene transformer provides the memory device for sex determination via its auto-regulation; only in females is functional TraExpand

The Gene Transformer of Anastrepha Fruit Flies (Diptera, Tephritidae) and Its Evolution in Insects
In the tephritids Ceratitis capitata and Bactrocera oleae, the gene transformer acts as the memory device for sex determination, via an auto-regulatory function; and functional Tra protein isExpand

The gene doublesex of Anastrepha fruit flies (Diptera, Tephritidae) and its evolution in insects
The doublesex (dsx) gene of several Anastrepha species was isolated and characterised. Its molecular organisation was found to be the same in all the species examined. This gene is composed of fourExpand

Eggshell morphology in two cryptic species of the Anastrepha fraterculus complex (Diptera : Tephritidae)
The external morphology of eggs of 2 cryptic species of the Anastrepha fraterculus (Wiedemann) complex, species 1 and species 2, was studied by scanning electron microscopy. Eggs of species 1 are, onExpand
