The composition of a chloroform seed extract of C. papaya was determined by GC-MS. Nineteen compounds were identified, with oleic (45.97%25), palmitic (24.1%25) and stearic (8.52%25) acids being the main components. The insecticidal and insectistatic activities of the extract and the three main constituents were tested. Larval duration increased by 3.4 d and 2.5 d when the extract was used at 16,000 and 9,600 ppm, respectively, whereas the pupal period increased by 2.2 d and 1.1 d at the same concentrations. Larval viability values were 0%25, 29.2%25, and 50%25 when the extract was applied at 24,000, 16,000, and 9,600 ppm, respectively; pupal viability was 42.9%25 and 66.7%25 at 16,000 and 9,600 ppm; and pupal weight decreased by 25.4%25 and 11.5%25 at 16,000 and 9,600 ppm. The larval viability of the main compounds was 33.3%25, 48.5%25, and 62.5%25 when exposed to 1,600 ppm of palmitic acid, oleic acid, or stearic acid, respectively. © 2011 by The Authors.
