Abstract

The losses to aphid as a pest are in the range of 6% to 25% and as vector it produce more than 80% of losses which is closely related to the age and variety to compare population of A. gossypii pest can of plant. The research objective was insect and Coccinelidae beetle on curly chili pepper and hot chili peper. Observation of aphid population on curly chili pepper and hot chili pepper plants were consisted of 100 plants samples, respectively. Observation Coccinelidae beetle population on curly chili pepper and hot chili pepper plants were respectively consisted of 200 plant samples. The aphid population and its predators were visual ly observed. The aphid population on curly chili pepper had higher population fluctuation than the aphid population on hot chili pepper. The highest population of aphid was found on 42-days-old curly chili pepper crop (241 aphids/100 plants), whereas the lowest one was found on 7-days-old curly chili pepper crops (0 aphids/100 plant). In contras, the highest population of aphid was found on 42-day-old hot chili pepper crop and the lowest one was found on 7, 14, 21, and 63 days after planting, respectively. Population of Coccinelidae beetle on curly chili pepper had higher population fluctuation than that of Coocinelidae beetle on hot chili pepper. Coccinelidae beetle found on the above chili plants consisted of thee types invoving 1 'Anisolemnia dilatata, 2. Coccinella transversalis and 3. Coccinella octomaculata.
