- Pests which attack paddy crop in plants field is brown planthopper. Brown planthoppers (Nilaparvata lugens. Stal) can se the damage for paddy crop in the field, so it can reduce production level national rice. The objective of this research was to analyze the field of biotypes of brown planthopper (Nilaparvata lugens. Stal) from Serang District, Lebak District, and Pandeglang District in Banten Province. The research was conducted on April to July, 2014 at the Indonesian Centre for Rice Research Sukamandi – Subang. It used descriptive qualitative method. Identification of biotypes brown planthopper using 8 differential varieties TN1, Mudgo (Bph1), ASD7 (bph2), Rathu Heenati (Bph3), Babawee (bph4), ARC 10550 (bph5), Swarnalata (Bph6), PTB 33 (bph2+Bph3), 5 varieties from IRRI such as IR26, IR42, IR64, IR72, IR74.

Scoring time was done when 90% check TN1 die or die completely is between 7-10 days after infestation. The result of brown planthopper biotypes test them Banten Province (Serang, Lebak, and Pandeglang) was biotype 4. it caused by varieties PTB33 which has endurance of gen (bph2 + Bph3) could hold out of the brown planthopper, whereas Bph1 gene (Mugdo) and bph2 (ASD7) could not maintain its endurance from brown planthopper.
