Daftar Isi:
- The objective of this research was to determine the response of six rice varieties to field population of the rice brown planthopper, Nilaparvata lugens. The experiment employed a completely randomized design with six rice varieties as treatments (Situ Bagendit, IR 64, Inpari 13, Ciherang, Conde, dan Mekongga) and each was replicated three times. The population of N. lugens and its predator was observed regularly starting on the 15th day after planting with an interval of seven days. If ANOVA showed differences, mean significant differences were tested using DMRT. The population of N. lugens during the whole rice season in general was considered very low. Therefore, differences among six varieties in response to N. lugens was not prominent. The highest population of N. lugens was found in Mekongga (6 N. lugens/hill) and the lowest population was in Inpari 13 ( 3 N. lugens/hill). Similar to N. lugens the populations of Pardosa pseodoanulata was highest in Mekongga.
