Abstract

Integrated Pest Management (IPM) is a pest control method that combines several control techniques by considering ecological, economic, and sociological consequences. Management efforts with IPM principles can be conducted by cultivating healthy plants and entomopathogen application. This study examined the IPM package's success for controlling fall armyworm (Spodoptera frugiperda) in maize field. This research was conducted in a farmer's maize plantation in the West Pasaman District from August to December 2021. The study used a Randomized Block Design (RBD) which consisted of three treatments and five replications. The treatments were different cultivation techniques using IPM, Non-IPM, and control. The variables observed were the population of S. frugiperda (individual/plant), attack rate (%), attack intensity (%), cob weight (g/cob), and farming cost (IDR). The results showed that the IPM and Non-IPM maize cultivation techniques had no different effect on S. frugiperda, especially survival stage, attack rate, intensity, and yield. However, this effect was higher than the control. In addition, the economic benefits of cultivation with IPM were higher than non-IPM. Therefore, this IPM package can be recommended for controlling S. frugiperda because it is also economically profitable and environmentally friendly.

Abstract

Parasitoid Hymenoptera is an important natural enemy of most plant pests, and it can control pests specifically in the agricultural ecosystem. The study aimed to study parasitoid Hymenoptera diversity in agricultural and primary forest ecosystems. The research was conducted from March to June 2018 at Lubuk Kilangan Subdistrict, Padang. The research location was determined by purposive sampling, and sampling was taken using malaise and yellow traps. The results showed that the family of parasitoid Hymenoptera with dominant numbers of individuals and morphospecies were Braconidae, Ichneumonidae, and Scelionidae. The diversity index of both ecosystems is classified as high, with a value of 4,879 for primary forest ecosystems and 4,675 for agricultural ecosystems. The Evenness index of both ecosystems is classified in the high category, with a value of 0,905 for the primary forest ecosystem and 0,887 for the agricultural ecosystem. The similarity index of both ecosystems is classified in the high category with a value of 0,607.
