IF males of one strain of C. pipiens are crossed with females of a strain from a different geographical area, the number of offspring may be either normal or small, or there may be none at all1. These three results have been called compatible, partially compatible and incompatible, respectively. Reciprocal crosses may give the same or different results. For example, strain A males may be fully compatible with strain B females, but strain B males may be compatible, incompatible, or only… Expand

Topics from this paper

The etiological agent of cytoplasmic incompatibility in Culex pipiens.
Abstract All individuals of Culex pipiens (wide sense) which have been examined were infected with Wolbachia pipientis . Larvae reared in tetracycline were freed of these symbiotes and remained freeExpand
Ultrastructural evidence of Wolbachia rickettsiales in Drosophila simulans and their relationships with unidirectional cross-incompatibility
TLDR
TEM examination of two unidirectional cross-incompatible strains of Drosophila simulans showed intracellular procaryotes in the ovaries of the C strain and of the F1 offspring of the ♀C × ♂P crossing, which seemed to be very similar to the rickettsia Wolbachia pipientis already described in mosquitoes.

Cytoplasmic incompatibility in the mosquito Culex pipiens L. from southern France: implications for the selection and dispersal of insecticide resistance genes in natural populations
Cytoplasmic incompatibilities were observed between strains derived from various natural populations of Culex pipiens in southern France. Their existence in a restricted geographic area heavilyExpand
The effect of tetracycline on nonreciprocal cross incompatibility in
TLDR
Certain stocks of the parasitic wasp Mormoniella vitripennis exhibit nonreciprocal cross incompatibility, believed to be caused by a maternally inherited cytoplasmic agent. Expand
Reproduction of an inbred strain of Culex pipiens prevented by loss of Wolbachia pipientis.
Abstract The development time for an autogenous strain of Culex pipiens was prolonged after the mosquitoes were “cured” of their symbiotic Wolbachia pipients with tetracycline. Eggs produced byExpand
INCOMPATIBLE RACES OF EUROPEAN CHERRY FRUIT FLY, RHAGOLETIS CERASI (DIPTER A: TEPHRITIDAE), THEIR ORIGIN AND POTENTIAL USE IN BIOLOGICAL CONTROL
TLDR
International investigations on the unidirectional incompatibility between two races of Rhagoletis cerasi discovered in 1972 have yielded a new distribution map of the observed phenomenon, indicating that the observed sterility is caused by extra‐chromosomal factors. Expand
Non-reciprocal fertility among species of theAedes (Stegomyia) scutellaris group (Diptera: Culicidae)
TLDR
A crossing scheme is proposed to explore the genetic basis of non-reciprocal fertility between two species by crosses involving a third mutually compatible species. Expand
Crossing type variability associated with cytoplasmic incompatibility in Australian populations of the mosquito Culex quinquefasciatus Say
TLDR
Analysis of cytoplasmic crossing type variation in Australian populations of Culex quinquefasciatus revealed high levels of variability causing partial incompatibility between natural populations, and the nature of the observed variation did not support the hypothesis of paternally expressed nuclear ‘restorer’ genes. Expand
Cytoplasmic Incompatibility as a Means of Controlling Culex pipiens quinquefasciatus Mosquito in the Islands of the South-Western Indian Ocean
TLDR
The feasibility of the Incompatible Insect Technique (IIT), a species-specific control approach in which field females are sterilized by inundative releases of incompatible males, is explored and the Wolbachia wPip(Is) strain is shown to be a good candidate to control Cx. Expand
Wolbachia and the normal and incompatible eggs of Aedes polynesiensis (Diptera: Culicidae)☆
TLDR
Embryos developed in as many as 10% of the incompatible eggs and these developed into both males and females, which indicates that the surviving embryos were not parthenogenetic. Expand

The Rickettsia, Wolbachia pipientis (gen. et sp.n.) and Associated Inclusions of the Mosquito, Culex pipiens
TLDR
The invariable presence of a rickettsia in the gonads of the mosquito, Culex pipiens, is confirmed and the pathological germ cells previously noted in the testis by cytologists were found to occur in both sexes at all stages, and to be apparently the result of infection with this ricksettsia.

It must be admitted that the evidence is less compelling for denying mature virus any role in the viral genetic continuity through fly generations, and the chapter concludes with a discussion on the effect of a rise in temperature on the host–virus relationships. Expand
