ITALIANO: Si riportano i risultati di 3 prove di lotta contro F. occidentalis (Perg.) condotte nel biennio 90-91 in una serra di rose cv. "Sonia". Tra gli insetticidi saggiati metiocarb (140 g/hl), formetanato (90 g/hl) e la miscela lambda-cialotrina + abamectina (1.75 + 0.4 ml/hl) si sono rivelati in grado di tener sotto controllo popolazioni di tripidi di consistenza molto elevata. Con un grado d' azione decrescente seguono profenofos, fentoato e lambda-cialotrina, quindi ometoato, metidation, ossidemeton-metile, acefate, monocrotofos, metomil e abamectina. Quest'ultimo principio e' risultato attivo soprattutto verso le neanidi. Infine fenoxicarb si e' rivelato del tutto inefficace. L'impiego di fentoato ha provocato la comparsa di sintomi di fitotossicita' sui petali.

Among the tested pesticides, sprayed 2 times with an interval of 7 days, methiocarb (104 g/100 l), phenthoate (90 g/100 l) and the mixture lambda-cyhalotrine + abamectin (1.75 + 0.4 ml/100 l) gave the best results in presence of a high population density. Partial efficacy was obtained by profenophos, phenthoate and lambda-cyhalotrine, while omethoate, methidathion, oxydemeton-methyl, acephate, monocrotophos, methomyl and abamectin were even less effective. The last one was active principally on the immature stages. Fenoxycarb appeared completely ineffective. Under our condition phenthoate resulted strongly phytotoxic causing petal necrosis.
