Abstract
Biology of Micraspis discolor was studied under laboratory condition (26±2ºC, 65±3% RH) at Department of Biotechnology, Mandalay Technological University. It has been found that incubation period and total larvae period were 4.6±0.7 days and 8.5±0.5 days. The larvae passed through four instars within 8 to 9 days. The female and male longevity were 44.6±4.0 and 34.8±4.6. Moreover, predatory potential of Micraspis discolor was studied on black aphids. The result indicated that predation rate of 1st instar grub was 37.5±4.6 and 4th instar grub was 51.7±9.8. The male predation rate (51.1±16.1) and female predation rate (57.8±16.4) were observed under the same conditions. This result concluded that the females of M.discolor were higher than the males in longevity and predation rate.
