While there's a discussion on the greater bulb fly, I ask if anyone has experiences with the lesser bulb fly Eumerus tuberculatus. This pest is causing me several losses of big Brunsvigia, Amaryllis belladonna Multiflora, Veltheimia capensis. It seems to like the bigger bulbs, partially emerging from the soil. The imidacloprid is not effective so far, I have spried the plants while in leaf past season. Angelo Porcelli Apulia - Southern Italy
