Wolbachia endosymbionts are ubiquitously found in diverse insects including many medical and hygienic pests, causing a variety of reproductive phenotypes, such as cytoplasmic incompatibility, and thereby efficiently spreading in host insect populations. Recently, Wolbachia-mediated approaches to pest control and management have been proposed, but the(More)
The reduction of acetate ester synthesis by aeration and the addition of unsaturated fatty acids to the medium has been reported to be the result of the reduction in alcohol acetyltransferase (AATase) activity induced by inhibition of this enzyme. However, regulation of the AATase gene ATF1 has not been reported. In this study, ATF1 gene expression was(More)
The European honeybee, Apis mellifera L. (Hymenoptera: Apidae), has a full set of machinery for functional CpG methylation of its genome. A recent study demonstrated that DNA methylation in the honeybee is involved in caste differentiation. In this study, the expression and methylation of the hexamerin 110 gene (Hex110), which encodes a storage protein, was(More)
WO is a temperate bacteriophage that infects Wolbachia, a maternally inherited endosymbiont of arthropods. WO has lysogenic and lytic cycles, the latter of which is an important process for the spread of WO infection. In this study, we measured the lytic activities of two WO phages, WOCauB2 and WOCauB3, infecting a Wolbachia strain, wCauB. In the lytic(More)
The potential uses of baculovirus as a gene vector to queen honeybees were examined in this study. We used a green fluorescent protein-expressing baculovirus with wild-type envelope and two pseudotype viruses of which one overexpressed GP64 and the other expressed a virion protein of a honeybee virus on the envelope. After injection of these baculoviruses(More)
