[Sex ratio and male killing in Siberian populations of Harmonia axyridis (Pass.)].
In populations of Harmonia axyridis Pall. from Novosibirsk and Kyzyl, females (three out of 34 studied) that produce exclusively female progeny were found. In one of the families studied, the inheritance of the male-killing trait was monitored over five generations. The male-killing trait was maternally inherited. The beetles of this family were infected with the bacteria that, according to the sequence analysis of the gene fragment for 16S rRNA, belong to the genus Spiroplasma (VI group).
