إنجليزي. Laboratory trials were carried out to test the effectiveness of ten pesticides on Orius majusculus Reuter. Newly moulted third-instar nymphs were exposed to fresh spray pesticide deposits for 7 days followed by a check of the mortality, the development into adults and the egg deposition. Bacillus thuringiensis (21.2%), pirimicarb (8.3%), chlofentezine (0%) and copper oxychloride (20.2%) had no appreciable effects. Colloidal sulphur (55.4%) and endosulfan (77.4%) resulted slightly harmful, heptenophos (91.2%) was moderately harmful, while acephate (100%), deltamethrin (100%) and dimethoate (100%) completely killed the nymphs. These results indicate that the different selectivity level of the products imposes a correct choice for the use of some of the products, where biological control programs with Orius are adopted

إيطالي. Sono state eseguite prove di laboratorio allo scopo di valutare il livello di tossicita' di dieci fitofarmaci verso Orius majusculus (Reuter). Ninfe neoformate di ninfe di terza eta' sono state esposte per sette giorni a contatto con i residui dei fitofarmaci ed in seguito e' stata valutata la mortalita', lo sviluppo allo stadio adulto, nonche' la fertilita' delle femmine. Bacillus thuringiensis (21.2%), pirimicarb (8.3%), chlofentezine (0%) e ossicloruro di rame (20.2%) hanno evidenziato buona selettivita'. Zolfo colloidale (55.4%) e endosulfan (77.4%) sono risultati debolmente tossici, heptenophos (91.2%) ha manifestato media tossicita', mentre acephate (100%), deltametrina (100%)e dimetoato (100%) sono risultati altamente tossici, determinando la completa mortalita' delle ninfe a contatto residuale, poco tempo dopo l'esposizione con questi prodotti. Il diverso livello di selettivita' riscontrato impone una giusta valutazione nella scelta di alcuni dei fitofarmaci saggiati, laddove sono previsti programmi di lotta biologica con Orius
