Tang, C. 1995 [Construction and analysis of the life table for natural population of the loblloly pine mealybug (Oracella acuta).]. Journal of South China Agricultural University 17(1): 31-36.

Notes: Construction and analysis of the life table for natural population of Oracella acuta in southern Guangdong province were discussed. Based on a systematic survey in a pine forest, the initial number and the survival rates in several stages were estimated respectively. Results showed that the trend index of population dynamics (1-values) of the pest from overwintering crawler stage to crawler stage of the 1st generation and the 1st generation complexing development were 5.70, 0.92 respectively. No parasitoids were observed on the mealybug nor was a suppression effect of predators on apparent. The exclusive index of population control (EIPC) was 1.26, i.e., the next population of the pest would increase 1.26 times if natural enemies were excluded.
