Delia antiqua

Fipronil s high intrinsic activity against Dipterans allows its successful use as a seed treatment in several crops for control of root maggots. In cereals, fipronil provides excellent control of wireworm and wheat bulb fly (Delia coarctata) at rates of 50 g per 100-kg seed [8]. In leeks, seeds film[Pg.1062]

Several species of insects are associated with Allium species. For example, both adults and larvae of Delia antiqua, the onion fly, are atb-acted to disulfides characteristic of these plants (Stadler, 1992). Another specialist, the leek moth, Acrolepiopsis assectella, was found to respond to the same group of compounds. However, dipropyl sulfinate, the precursor of the disulfides, is even more stimulatory. A parasite of the leek moth, Diadromus pulchellus (Ichneumoni-dae), reacts mainly to the disulfides that emanate from leaves damaged by the leek moth (Stadler, 1992).
