Abstract: In order to understand the reproductive capacity of Pomacea canaliculata in different regions of Guangxi and its influencing factors, six habitats （rice field, waste field, gutter, pond, river, swamp） in Guilin, Laibin and Beihai in Guangxi, were collected from July to August 2018. The length, width and weight of the eggs mass and egg diameter as well as the total number of eggs were measured. The correlations between incubation rate and these factors were analysed, respectively. The results showed that the number of single egg grains was 48~1 041, and the mean value was （256.19±155.67）. The number of eggs in the pond habitat was the highest, and the mean value was （395.61±213.33）. The number of eggs in waste field was the lowest, the mean value was （168.39±55.47）; The egg diameter was 1.72~2.72 mm, mean value was （2.17±0.17） mm, and the diameter of the ditch habitat was the largest and the mean was （2.32±0.13） mm. The diameter of the egg in the rice field was the smallest, and the mean value was （2.07±0.16） mm. The number of egg grains and the diameter of egg grains in different areas were Laibin > Guilin > Beihai. The number of egg grains between habitats showed pond > river > swamp > ditch > paddy field > waste field. The diameter of the egg grains in the habitat was pond> swamp> ditch > river > waste field > rice field. Pomacea canaliculata in Guangxi in the summer was not related to latitude. The habitats with high water surface height or food were rich, and the number of eggs was larger and the diameter of the egg grains was larger. There were significant differences in egg number and egg diameter between different regions and habitats.
