    Abstract

    The rose aphid, Macrosiphum rosae (L.), was tested for its ability to produce sexual forms on rose leaves, after induction by environmental conditions in the field and in the laboratory. Clones were collected in Tübingen, Federal Republic of Germany, and in south‐eastern New South Wales, Australia. The German clones all produced sexual forms, while the response of the Australian clones was weak. There appeared to be a bias in the sex ratio towards females: This is discussed in developmental terms. The environmental and genetic factors influencing the response are considered. 1991 The Netherlands Entomological Society
