Influence of aging on cytoplasmic incompatibility, sperm modification and Wolbachia density in Culex pipiens mosquitoes

Article Abstract:

The influence of aging on cytoplasmic incompatibility, sperm modification and Wolbachia density in Culex pipiens mosquitoes is studied. It is seen that that cytoplasmic incompatibility (CI) persists at the same intensity throughout the mosquito life span and embryos from incompatible crosses showed even distribution of abortive phenotypes over time, suggesting that host ageing does not reduce the sperm-modification induced by Wolbachia.

Multiple infections and diversity of cytoplasmic incompatibility in a haplodiploid species

Article Abstract:

Cytoplasmic incompatibility (CI) effects in crosses involving insect lines sharing the same nuclear background and harboring different mixtures of strains are compared. CI was induced by all the three Wolbachia strains infecting L. heterotoma and a bidirectional incompatibility is found in wLhet2 and wLhet3 that induces an intermediate CI when acting alone.

Bidirectional incompatibility among divergent Wolbachia and incompatibility level differences among closely related Wolbachia in Nasonia

Article Abstract:

The article discusses about the independent acquisition of divergent A Wolbachia that has resulted in three mutually incompatible strains whereas codivergence of B Wolbachia in Nasonia longicornis and Nasonia giraulti is associated with difference in cytoplasmic incompatibility (CI).
