This in vitro study evaluated the effects of crude alkaloid compounds extract plant A. majus leaves and flowers on some biological performance aspects insect. The results showed that at concentrations 10, 20 30 mg/ml significantly affected cumulative mortality different stages. concentration ( 30) had most noticeable effects, causing highest rate second fourth larval instars (86.7 73. 3 %, respectively) after 72 hours. At same time, rates upon applying but were 73.3, 53.3 respectively, following hours treatment. Keywords: Oryzaephilus surinamensis; Ammi majus; extract.
