In Drosophila, Dsrc64 is considered a unique ortholog of the vertebrate c-src; however, we show evidence to the contrary. The closest relative of vertebrate c-src so far found in Drosophila is not Dsrc64, but Dsrc41, a gene identified for the first time here. In contrast to Dsrc64, overexpression of wild-type Dsrc41 caused little or no appreciable(More)
Some aphid species are attended by ants, which protect aphids against enemies, but ants sometimes prey on the aphids they are attending depending on the resource conditions. A previous study indicated that the ant Lasius niger preys less on the aphid individuals that experienced ant attendance than on those that did not. This observation leads to the(More)
Aphid-tending ants protect aphids from natural enemies and collect honeydew secreted by the aphids. However, ants also often prey on the aphids they attend. Aphids, therefore, like social parasites of ants, may well have evolved chemical mimicry as an anti-predation strategy. In this study, we aimed to determine whether the aphid Stomaphis yanonis actively(More)
