Cytoplasmic incompatibility in social insects
In this essay, I briefly summarise reproductive phenotypes associated withWolbachia in insects, present a model of the dynamics of infection frequency for maternally-inherited microorganisms and determine the effect of changing costs associated with incompatibility, infection-related fecundity loss and number of mates in ideal populations of social insects. The model predicts that infections of...
متن کاملPopulation genetics of haplodiploid insects.
Genic variation of seven species of Hymenoptera is described, using electrophoretic techniques. The heterozygosities range from 0.033 to 0.084. An average heterozygosity is calculated for 23 species of haplodiploid insects, and this value is significantly different from the same value for 18 Drosophila species or for 24 diploid insect species (including Drosophila). The niche width-genetic vari...
متن کاملHost genotype determines cytoplasmic incompatibility type in the haplodiploid genus Nasonia.
In haplodiploid species, Wolbachia-induced cytoplasmic incompatibility (CI) can be expressed in one of two ways: as a "conversion" of diploid fertilized eggs into haploid males or as embryonic mortality. Here we describe CI-type variation within the parasitic wasp genus Nasonia and genetically analyze the basis of this variation. We reach four main conclusions: (i) CI is expressed primarily as ...
متن کاملResponse to “Does pupal communication influence Wolbachia-mediated cytoplasmic incompatibility?”
In a recent Current Biology paper [1], we reported that pheromone communication occurred during metamorphosis in Drosophila melanogaster. Female pheromones appeared to influence various aspects of the physiology and development of adult males. In particular, we observed that this communication regulated testis development and had a positive impact on reproduction, as measured by a difference in...
متن کاملDoes pupal communication influence Wolbachia-mediated cytoplasmic incompatibility?
Wolbachia are widespread endosymbiotic bacteria found in terrestrial arthropods and filarial nematodes [1]. In insects, Wolbachia generally rely on diverse strategies to manipulate their host's reproduction and favor their own vertical transmission through infected eggs [2]. One such mechanism is a sterility syndrome called 'cytoplasmic incompatibility'. Cytoplasmic incompatibility occurs at fe...
