摘要: Plutella xylostella L. is one of the main agents to cause damages plants Brassica genus, provoking negative impacts in cultures. The use botanical extracts protection has been related literature, however, their species analyzed this study not yet reported. We assessed effect aqueous and methanolic species: Schinus terebinthifolius Raddi (Pink Pepper), Annona coriacea Mart. (Araticum), Duguetia furfuracea (A. St.-Hil.) Benth. & Hook. (Pindauva do campo) Trichilia silvatica C. DC. (Catigua-branco), occuring state Mato Grosso Sul whose feeding preference P. larvae 3rd instar. intend answer following questions: (1) Are plant fagodeterrentes? (2) what type extract produces least food preferrence? To these questions, we treated cabbage disks with stored a refrigerator periods 0, 7, 14 21 days were at concentrations 0.5 mg/mL, 1.0 2.0mg/mL. T. presented lowest values preference, 0.113 0.06, respectively, compared other extracts.
