Relative Wolbachia density of field-collected Aedes albopictus mosquitoes in Thailand
Journal of Vector Ecology 33 (1), 173-177
Abstract: Female Aedes albopictus mosquitoes from natural populations of different geographical regions of Thailand were collected and allowed to oviposit to determine relative Wolbachia A and Wolbachia b densities of their offspring (F1) by using real-time quantitative Pcr (rTQ-Pcr). An important aspect of this work is that all Aedes albopictus mosquitoes were collected from the field. Twenty-seven offspring were from diverse areas of Thailand (songkhla, Konkaen, chantaburi, and Kanchanaburi). The range of relative Wolbabhia A density in F1 mosquitoes was from 0.007 to 1250.78 (bacteria-to-host ratio), whereas relative Wolbachia b densities ranged from 0 to 348.2 (bacteria-to-host ratio). These data are in contrast to those from a previous study that showed a very low amount (less than 0.10) of both relative Wolbachia density types for laboratory strains. The percent transmission of Wolbachia density from mother to each individual offspring cannot be predicted and was not related to the sex of the F1. Obtaining confirmation for variations and unpredictable Wolbachia transmission load raises some concerns about using Wolbachia as a gene-driving system in nature for population replacement if Wolbachia density is involved in cytoplasmic incompatibility in this mosquito.
