Abstract

Spodoptera frugiperda is one of the most important leaf pests because it has a wide host range including food crops, industrial crops and horticultural crops. First instar larvae damage plants by boring into leaves and eating leaf tissue, leaving transparent marks on the leaf surface. Corn is a food crop that is a substitute for rice which is very important for human needs. In addition, corn also has a very important role as the main raw material in the animal feed industry. This study used the Completely Randomized Design (CRD) method with 5 treatments repeated 4 times, resulting in a total of 20 experimental units. The treatments applied were as follows: k0 = 0% (100 ml of distilled water), k1 = 10% (10 ml of iwi leaf extract + 90 ml of distilled water), K2: 20% (20 ml of iwi leaf extract + 80 ml of distilled water) K3: 30% (30 ml of iwi leaf extract + 70 ml of distilled water). K4: 40% (40 ml of iwi leaf extract + 60 ml of distilled water. The results of this study indicate that the use of iwi leaf extract has no significant effect on armyworm pests. On all observed parameters.

Abstract

The presence of pest attacks on rice plants can cause significant damage. The purpose of this study was to determine the species of pests that attack rainfed rice plants, which is essential in determining and considering the correct pest identification and management. The research method employed in this study is a qualitative approach with observational techniques, where researchers conduct fieldwork to identify the types of pests that attack rice plants. Data collection was carried out at 5 different locations selected randomly. The research parameters are pest type, pest frequency, and pest attack intensity. The results of the study showed that several pests attacked rice plants in Umbu Pabal Selatan Village, Umbu Ratu Nggay Barat District, including golden apple snails (Pomacea canaliculata) and rice stem borers (Scirpophaga Innotata). The frequency of pest occurrence at the research location showed that golden apple snail pests dominated, with a high category (67-81%), and rice stem borer pests fell into a moderate category (23-50%). The level of pest attack intensity varied between locations, with categories ranging from light to heavy, corresponding to percentages of 23-50%.
