摘要

Wild radish (Raphanus raphanistrum) (Brassicaceae) is one of southern Australia's worst weeds of cropping. The potential for biological control of this weed in Australia is being investigated in the weed's original distribution, southern Europe and the circum-Mediterranean region. Surveys for insects and pathogens have been made throughout the Mediterranean region, concentrating on southern Portugal, northern Tunisia, the Mediterranean coast of France, and southern Greece. While many of the organismsfound are specialists on the family Brassicaceae, most of these are not sufficiently host specific to exclude the risk to canola (Brassica napus), the most important crop related to wild radish. Another close relative is the edible radish (Raphanus sativus). Wild indigenous populations of edible radish are not known and it has been hypothesised that edible radish has been developed in antiquity from wild radish, even though they are classified as separate species. For this reason, emphasis has been placed on finding biological control agents that attack the seed or reproductive parts of the wild radish or have a host range restricted to wild radish. Agents reducing seed set that are being studied include insects that are highly specialised in their mode of feeding on the plant such as the flower gall fly Gephyraulus raphanistri, an insect that has only been recorded from wild radish.
