Abstract

One of the control techniques for the brown planthopper or BPH (Nilaparvata lugens Stal) is resistant varieties. This study aimed to determine the resistance level of several rice varieties (Oryza sativa Linnaeus) to the BPH of the Karawang Population. The study was located at the Entomology Laboratory, Center for Predicting Plant Pest Organisms (BBPOPT) Jatisari, Directorate General of Food Crops, Ministry of Agriculture, Indonesia, from July to August 2022. The study was conducted in a Completely Randomized Design (CRD) with ten treatments and five replications. The treatment was in the form of different rice varieties (Pelita, Inpari-33, Inpari-47, Inpari-48, Ciherang, Cilamaya Muncul, Mapan, Situ Bagendit, M-400, IR-64). Parameters observed were spot area, spot area conversion, and determination of resistance. The results showed that the resistance of some of the tested rice varieties to BPH of the Karawang population was classified as moderate to moderately resistant. Inpari-47, Inpari-48, IR-64, M-400, Inpari-33, Cilamaya Muncul, and Situ Bagendit are moderately resistant, while Mapan, Ciherang, and Pelita have moderate resistance. The results of the honeydew test can be compared with other resistance test methods.

Abstract

Brown planthopper or BPH (Nilaparvata lugens Stal, Hemiptera: Delpachidae) is a significant pest that is a severe problem to rice plants in various places, including Bogor District, East Java Province. Resistance of several varieties of rice to BPH of Bogor Population has not been reported. One method to determine a variety's resistance is the honeydew test. This study aims to determine the resistance of several rice varieties to BPH of Bogor population. This study used six different varieties as treatments, and carried out in five replications. Those varieties were Pelita, Mapan, Situ Bagendit, Ciherang, Inpari-33, and IR-64. The observations were made on the area of honeydew spots produced by BPH after consuming sap of rice plant. This research showed that the Situ Bagendit variety was relatively resistant to BPH of Bogor population. The Mapan and Pelita varieties were quite susceptable, while Inpari-33, Ciherang, and IR-64 were moderate. The region of origin where BPH grows and the testing procedure can affect the resistance category of one variety.
