The research was conducted at the Department of Plant Protection, Faculty of Agronomy and Applied Biology, Can Tho University from December 2009 to September 2010 and aimed to study the morphology and the biology of Iceryia aegyptiaca Douglas. Nymphs of I. aegyptiaca were collected from infested roses in Can Tho city and reared on potted roses till adult stage and were allowed laying eggs in the green house at 25 - 35°C and 65 - 90 percent RH. The first generation of nymphs of I. aegyptiaca were collected and allowed to grow and develop into adults. Results showed that the average life cycle of I. aegyptiaca was about 62.67 +/- 1.51 days, including 6.67 +/- 0.47 days for egg incubation, 34.00 +/- 0.27 days for nymphal stages and 22.00 +/- 1.41 days for pre-oviposition stage. I. aegyptiaca is able to lay up to 215 eggs. The longevity is 47.00 +/- 3.35 days. Males did not occur in the population of I. aegyptiaca. Owing to the research, the morphological characteristics of I. aegyptiaca have been described.
