ABSTRACT
The brown planthopper (Nilaparvata lugens Stal) is the main pest of rice plants around the world, because it can cause crop failure or crop loss. One technique to control brown planthopper is to use resistant varieties. The research of honeydew test method aimed to determine the resistance level of several rice varieties (Oryza sativa Linnaeus) against brown planthopper (Nilaparvata lugens Stal) from Karawang population. This research was conducted at the Entomology Laboratory of the Forecasting Center for Plant Pest Organisms (BBPOPT) Jatisari, Directorate General of Food Crops, Ministry of Agriculture, Indonesia. The study was carried out from July to August 2022. The application of the resistance test of rice varieties to brown planthoppers was applied using the honey dew test method using bromocressol green indicator paper as an alternative to describe the broad distribution of spots secreted by the brown planthopper. Parameters for pecking are extensive conversion analysis of spots, large percentages of spots, and broad finder’s fees with testing of 10 varieties of rice (Pelita, Inpari-33, Inpari-47, Inpari-48, Ciherang, Cilamaya muncul, Mapan, Situ bangendit, M-400, IR-64) in five replications. The results showed that Inpari-33, Inpari-47, Inpari -48, Cilamaya muncul, M-400, and IR-64, Situ Bagendit had moderate resistance, whereas Mapan, ciherang and pelita had susceptable.
