ABSTRACT
Corn is one of the cereal crops that has economic value and has the opportunity to be developed. Apart from being used as a food source by the community, corn can also be used as a source of feed because it contains carbohydrates and protein. One of the factors that affect the production of corn is pest attack. This was caused by the attack of pests on maize, namely Fall Armyworm (Spodoptera frugiperda J. E. Smith). The aim of the study was to obtain data on attack levels, attack intensity of Fall Armyworm (Spodoptera frugiperda J. E. Smith) and larval parasitoids associated with Fall Armyworm larvae. This research has been carried out at 5 points of location for corn cultivation which are in the center of corn cultivation in Sidomulyo Barat Village, Tampan District, Pekanbaru City and at the Plant Pest Laboratory, Faculty of Agriculture, University of Riau, Bina Widya Campus km 12.5, Pekanbaru. The research has been carried out for 5 months. The research was carried out by collecting Fall Armyworm larvae from the field and rearing Fall Armyworm larvae in the laboratory. Parameters observed were the number of Fall Armyworm pests, the level of attack, the intensity of the attack, the number of parasitoids, the level of parasitization, the sex ratio. The results showed that the attack rate of Fall Armyworm larvae on corn in Sidomulyo Barat Village, Tampan District, Pekanbaru City was 84.2% in the high category with 46.7% attack intensity in the medium category and no parasitoids associated with Fall Armyworm larvae were found.
