Uhan and Sulastrini (1993) reported in 1993 that C. pavonana populations from Lembang (West Java, Indonesia) were not resistant to a number of synthetic insecticides tested. Resistance status of C. pavonana to profenofos synthetic insecticide was reported previously by Santoso (1997). Suharti (2000) stated that C. pavonana of Lembang (Cibogo and Cikidang) had a Resistance Ratio (RR) value more than 4 times, which were 6.81 and 7.88. In Pangalengan (Pulosari and Warnasari) and Cisurupan (Sukawargi), C. pavonana also became resistant to profenofos with RR of 3.19, 1.59,and 1.50, respectively. Due to resistance cases of C. pavonana to profenofos synthetic insecticide, it is necessary to find new insecticides which are more effective and safer to the environment. Regular monitoring of resistance status is also required.
