Abstract

 One of the obstacles in efforts to increase rice productivity is the damage caused by the attack of the rice stem borer. Annual yield loss caused this insect pests is quite high, reaching 10-30%. The attack of stem borer has long been encountered and is a problem in rice producing areas on Buru Island, such as in Savanajaya Village. This study aimed to obtain data on the types of pests, population levels and the intensity of damage in five rice varieties due to stem borer attact and to determine the varieties that had the lowest population and damage intensity in the Saavanajaya Village, Waeapo District, Buru Regency. The method used was a survey method that focused on five varieties of rice cultivated by farmers, to obtain population data and the intensity of damage. The results showed that the type of pest that attacked the five rice varieties of IR-64 variety in Savanajaya Village was the white rice stem borer (Scirpophaga innotata), with the highest larval population (per cluster) of 1.27 individuals and the intensity of damage 5.20%, followed by Cigeulis variety with a larval population of 1.17 individuals and damage intensity of 4.70%, the Ciherang variety with a larval population of 1.07 individuals and damage intensity of was 4.25%, the Mekongan variety with a larval population of 1.1 individuals and damage intensity of 4.15%, and the lowest was the Membramo variety with a larval population of 1.03 larvae and damage intensity of 4.12%. The damage intensity of at the study site, although different between varieties, could all be classified into the category of mild attack. Keywords: damage intensity, rice varieties, Savanajaya, stem borer
