Penelitian ini bertujuan untuk mengetahui populasi hama dan intenstas serangan hama 
pada pertanaman berbagai galur padi yang mempunyai kemampuan menghasilkan 
protein tinggi. Rancangan penelitian yang digunakan yaitu Rancangan Acak 
Kelompok (RAK), dengan perlakuan empat genotipe tanaman padi berprotein tinggi 
(Protani, Protangguh, GN95A, dan GN95B) dan satu genotipe pembanding (Ciherang). 
Jarak tanam yang digunakan yaitu 20 cm x 20 cm. Variabel yang diamati meliputi 
populasi dan tingkat kerusakan dua hama utama (wereng batang coklat, WBC dan 
walang sangit). Pengamatan variabel dilakukan secara sistematik, pada saat masa 
vegetatif (WBC) dan generatif (walang sangit). Populasi WBC pada semua genotipe 
tidak berbeda nyata. Populasi WBC tertinggi terdapat pada genotipe Protangguh, 
dengan 4,4 per rumpun. Populasi walang sangit berbeda nyata pada genotipe yang 
diuji, dengan kisaran 2-5 ekor per m2. Intensitas serangan WBC relatif rendah yaitu 
kurang dari 0,1% pada semua genotipe, sedangkan intensitas serangan walang sangit 
kisaran 10-16%. Hasil panen antar genotipe padi berbeda nyata pada bobot 100 biji, 
sedangkan hasil panen akibat serangan hama tidak berbeda nyata.

This research aimed to determine the population and intensity of pest attacks on various rice 
lines with high protein-yielding capabilities. It was conducted using a Randomized Complete 
Block Design (RCBD), with four high-protein rice genotypes (Protani, Protangguh, GN95A, 
and GN95B) and one control genotype (Ciherang). The planting distance used was 20 cm x 20 
cm. The variables observed included the population and damage level of two major pests 
(brown plant hopper and rice bug). Observations were conducted systematically during the 
vegetative (brown plant hopper) and generative (rice bug) phases. The results showed that the 
brown plant hopper population did not differ significantly among all genotypes. The highest 
brown plant hopper population range occurred in the Protangguh variety, with 4,4 individuals 
per hill. The rice bug population showed significant differences among genotypes, ranging 
from 11-20 individuals per plot or 2-5 individuals per m². The intensity of brown plant hopper 
attacks was relatively low, less than 0.1% in all genotypes, while the intensity of rice bug 
attacks ranged from 10-16%. The rice yield among genotypes differed significantly in terms of 
100-grain weight, while the yield loss due to pest attacks did not differ significantly.
