Abstract

The research about the characteristic of slug population (Parmarrion pupillaris) African wood nursery (Maesopsis eminii Engl.) area had been conducted from February to May 2011. The research was carried out directly in African wood nursery in Tempel Rejo Village Curup. Sampling was conducted by using Stratified Random Sampling. The results of the research indicated that population density of slug at the 4 month age strata of African wood nursery area was higher than other, as many as 1158 individuals with the population of density about 57.9 individuals/plot, and at the 2 month age strata gained as many as 850 individuals with the population of density about 42.5 individuals/plot. The highest number of colonies of eggs also found in the 4 month age strata that were 157 colonies with the total number of eggs was 4548 ranged between 18-46/colony and the average number of eggs about 29.15/colony. The Egg hatchability was 92.33% (hatched eggs was 4422 of 4548 total number of eggs). While at 2 month age strata there were only 100 colonies with the total eggs number as many as 2851 ranged between 17-47/colony and the average number of eggs about 28.51/colony. The Egg Hatchability was 87.22% (hatched eggs was 2758 of 2851 total number of eggs).
