Culex pipiens fatigans is the chief vector of filariasis in south-east Asia. Urbanization has often caused the numbers of this mosquito—and with it the danger of filariasis infection—to increase alarmingly1. The natural vigour, tolerance and fast development of resistance to insecticides of this mosquito necessitate the development of other control methods, and cytoplasmic incompatibility2 seems to be an ideal means. 

Culex Pipiens Fatigans

C.p. fatigans is known to breed in waters with varying degrees of pollution, primarily soakage pits, household drains, cesspools and puddles, but even in the absence of such water collections, the species readily breeds in clear waters such as wells and pools in river beds.

Beyond insecticides: new thinking on an ancient problem

Recent advances concerning vector control strategies are reviewed and the potential impediments to their deployment are considered, including the challenges of obtaining regulatory approval and community acceptance.

Wolbachia in Aedes mosquitoes: towards biological control of vector-borne diseases

This chapter reviews the possibility of applying the endosymbiotic bacteria Wolbachia pipientis as potential biological control of human diseases transmitted by mosquito vectors.

Wolbachia modulates prevalence and viral load of Culex pipiens densoviruses in natural populations

Analyzing the interactions between a widely prevalent ISV, the Culex pipiens densovirus (CpDV, Densovirinae), and Wolbachia in northern Tunisian C. pipiens populations provided good evidence for an ecological influence of WolbachIA on anISV, CpDVs, in natural populations and highlighted the importance of integrating Wolbachias in the understanding of ISV ecology in nature.

Non-reciprocal fertility among species of theAedes (Stegomyia) scutellaris group (Diptera: Culicidae)

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.

Crossing type variability associated with cytoplasmic incompatibility in Australian populations of the mosquito Culex quinquefasciatus Say

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.

Biology and Control of Culex Pipiens Quinquefasciatus Say, 1823 (Diptera, Culicidae) with Special Reference to Africa

Female behaviour during the different phases of the gonotrophic cycle is analysed, together with population dynamics, and control methods by synthetic insecticides are discussed in relation to resistance problems and the characteristics of the breeding sites.

Wolbachia pipientis: microbial manipulator of arthropod reproduction.

The alpha-proteobacterium Wolbachia pipientis is a very common cytoplasmic symbiont of insects, crustaceans, mites, and filarial nematodes that has evolved a large scale of host manipulations: parthenogenesis induction, feminization, and male killing.

The interactions of organophosphates with cholinesterase and the ion permeability of insect nerve, areas of special interest to the author and of general importance, are addressed.

Cytoplasmic Inheritance in Culex

There is no critical evidence enabling a choice between the two types of hypothesis for non-reciprocal fertility in Aëdes scutellaris, and cases of strictly maternal inheritance can be explained only by the two hypotheses mentioned by Smith-White and Woodhill.
