Functional anatomy of Dacus oleae Gmel. female genitalia in relation to insemination and fertilization processes

, 2016
In Dacus oleae the spermatozoa are transported free from male to female by direct injection of the semen into an « insemination pocket » located as an atrium at the entrance of the spermathecal ducts on the inner dorsal wall (roof) of the vagina.

The pumpkin fly Dacus frontalis (Diptera: Tephritidae): a new pest of curcubits in Tunisia.

, 2015
The pumpkin fly Dacus frontalis is reported in this paper for the first time in Tunisia, where it was found in several locations. It is a pest of cucurbits of economic importance and is common especially in the eastern and southern parts of Africa.

Allozyme variation in the fruit flies Dacus tryoni and Dacus neohumeralis (Tephritidae)

Biochemical Genetics, 1974
Electrophoretic variation in four specific proteins, an alcohol dehydrogenase, and an octanol dehydrogenase from adult body homogenates, an esterase from adult heads, and a tyrosinase from larval hemolymph, is described for laboratory populations of two sibling species, Dacus tryoni and Dacus neohumeralis.

The Status of Dacus armatus Fabricius and of Dacus bivittatus (Bigot) (Trypetidae, Diptera)

Bulletin of Entomological Research, 1948
A full consideration of the systematic position of Dacus armatus F. (the genotype of Dacus) and of Dacus bivittatus (Big.) is not attempted here, but it is necessary, owing to the economic importance of the latter, to clear up the confusion that has arisen between them. I am indebted to and thank Dr. A. J.

A Re-Evaluation of Introgression Between Dacus Tryoni and Dacus Neohumeralis (Diptera: Tephritidae).

Australian Journal of Zoology, 1977
The humeral calli in D. tryoni range from completely yellow to almost entirely brown. This variation is largely genetic and the character responds readily to selection in the laboratory. In field populations, selection favours flies with little or no brown pigment on the calli (around 3% brown) and there is a strong natural selection against the darker
