Paper Title
The Biology Of Micraspis Discolor And Study Of Its Predation Efficiency On Black Aphid

Abstract
Biology of Micraspis discolor was studied under laboratory condition (26�2�C, 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.
