English. The results from the investigations on the efficiency of some new insecticides for Dysaphis plantaginea Pass. (Homoptera Aphididae) and Leucoptera malifoliella O.G. Costa (Lepidoptera Lyonetiidae) control, are reported. Neem and chloronicotinyles (imidacloprid and acetamiprid) were the active ingrediens employed. The activity of this kind of a.i. was tested in comparison with other formulations: triazamate and mixtures including aminoacids and mineral oils. The experimentation gave out persuasive references, particularly regarding the chloronicotinyles for both the pests, while neem efficacy was satisfying against D. plantaginea and irrilevant against L. malifoliella. The addition of aminoacids to neem formulation gave out results in opposition to the expected ones

(Homoptera Aphididae) e Leucoptera malifoliella O.G. Costa (Lepidoptera Lyonetiidae). L'attivita' di questi prodotti e' stata comparata con quella di altri formulati: triazamate e miscele comprendenti aminoacidi e oli minerali. In particolare l'attivita' dei cloronicotinili (imidacloprid e acetamiprid) si e' dimostrata molto convincente nei confronti di entrambi i fitofagi, mentre neem e' risultato efficace per D. plantaginea e ininfluente per L. malifoliella. Per D. plantaginea l'aggiunta di aminoacidi a neem ha fornito risultati opposti a quelli attesi
