Abstract
ABSTRACT
This study aims to determine the percentage of attacks from caterpillar pest (C. pavonana) on cabbage plants in Rurukan, Paslaten and Kumelembuai, Tomohon City. The results of this study are expected to provide information about the attack of caterpillar pest (C. pavonana) on cabbage plants (B. oleracea) in Rurukan, Paslaten and Kumelembuai, Tomohon City. The research was carried out in Rurukan, Paslaten and Kumelembuai, Tomohon City which lasted for 4 (four) months, namely from March 2019 to June 2019. The research was conducted in a survey using the purporsive sampling method. In cabbage plants, plants were directly observed which showed symptoms of being attacked. Cabbage plants are considered attacked by caterpillars when they show symptoms, although larvae are not found. Sampling is done 6 (six) times at intervals of 1 (one) week. The results showed that the attack of caterpillar pest, C. pavonana in Paslaten, Rurukan and Kumelembuai showed varied attacks. The highest attack of C. pavonana was found in Rurukan, which was 50.58 percent and followed sequentially in Kumelembuai and Paslaten, which amounted to 31.58 percent and 23.75 percent.
Keywords : Cabbage plant, Crocidolomia pavonana, Tomohon.
