Transinfections of\n                    <jats:italic>Wolbachia<\/jats:italic>\n                    endosymbionts are now being used to introduce useful phenotypes into sexual host populations, but there has been limited progress on applications using other endosymbionts and in asexual populations. Here, we develop a unique pathway to application in aphids by transferring the endosymbiont\n                    <jats:italic>Rickettsiella viridis<\/jats:italic>\n                    to the major crop pest\n                    <jats:italic>Myzus persicae<\/jats:italic>\n                    .\n                    <jats:italic>Rickettsiella<\/jats:italic>\n                    infection greatly reduced aphid fecundity, decreased heat tolerance, and modified aphid body color, from light to dark green.

The phenotypic effects of\n                    <jats:italic>Rickettsiella<\/jats:italic>\n                    were sensitive to temperature, with spread only occurring at 19\u00a0\u00b0C and not 25\u00a0\u00b0C.
