Methyl bromide fumigation against Liriomyza huidobrensis
Fumigation of plant material with methyl bromide can be used against Liriomyza trifolii (EPPO A2 quarantine pest). An EPPO Phytosanitary Procedure had been proposed for chrysanthemum cuttings (EPPO, 1993) as a quarantine treatment to prevent spread of this pest in trade. Experiments have been carried out in United Kingdom on the effectiveness of such treatment against L. huidobrensis (EPPO A2 quarantine pest). Eggs, larvae and pupae were tested separately. Results obtained were similar to those obtained for L. trifolii and it is concluded that the treatment which is already recommended for L. trifolii (with a concentration time product of 54 mg.l-1h) is equally effective against L. huidobrensis. However, the absence of phytotoxicity should be verified when plants other than chrysanthemum are treated.
