摘要：

Thirteen tropical plants were evaluated for development-inhibiting activity against Sitophilus zeamais. The bioassays were carried out by incorporating seeds or leaves at various dose levels into an artificial diet for the test insect. It was found that seeds of Basella alba and leaves of Operculina turpethum and Calotropis gigantea were potent in delaying development and in reducing adult emergence, and hence the capacity for population increase. At 0.5% concentration, adult emergence in tests with B. alba, O. turpethum and C. gigantea was reduced by 62, 95 and 70%, respectively. In B. alba and C. gigantea, the development periods were 2.2 and 1.8 times those in the control and the capacities for increase/day were only 0.0324 and 0.0328 compared with 0.1004 in the control. B. alba, O. turpethum and C. gigantea were active at concentrations as low as 0.01, 0.05 and 0.1%. The potential of these materials in insect pest management is discussed.
