Abstract
Bembecia chrysidiformis (Esper) [Lep.: Sesiidae] was examined for its natural history and specificity toRumex spp. (Polygonaceae) which are weeds in Australia. Adults of this southern European insect appear in late spring to summer. Eggs are laid on the dried, seed bearing stems of perennialRumex plants. The larvae tunnel inside the root during summer through to the next spring. In nature, the larvae are round inRumex species of the subgeneraRumex andAcetosa. In host-specificity tests with 1st instar larvae, the roots of a number of genera within thePolygonaceae were attacked. Larvae died on a range of plants from other families except inPersea americana Miller(Lauraceae), Helianthemum nummularium (L.) Miller (Cistaceae) andQuercus ilex L. (Fagaceae) where larvae fed on the stems. The insect was judged safe for release in Australia by assessing aspects of its biology, its known host plants, and the lack of reported attack on other plants.
Résumé
Bembecia chrysidiformis (Esper) [Lep.: Sesiidae] a été étudiée pour ses possibilités de lutte contre les mauvaises herbesRumex spp. (Polygonaceae) en Australie. Les adultes de cet insecte sud-européen apparaissent entre la fin du printemps et l'été. Les œufs sont pondus sur les tiges florales des plantes deRumex spp. et les larves se développent dans les racines jusqu'au printemps suivant. Dans la nature on trouve des larves dans les plantes des sous-genresRumex etAcetosa. Dans les tests de spécificité avec les larves du premier stade, un certain nombre de genres au sein de la famille desPolygonaceae furent attaqués. Les larves ne survécurent pas sur les plantes appartenant à d'autres familles, sauf dansPersea americana Miller(Lauraceae), Helianthemum nummularium (L.) Miller (Cistaceae) etQuercus ilex L. (Fagaceae) où les larves attaquent la tige. Cet insecte fut jugé apte à être introduit en Australie après étude de sa biologie, de ses plantes-hôtes ainsi que de l'absence de cas d'attaque signalés sur d'autres espèces.
