ABSTRACTPopulation of Brown Plant Hopper (Nilaparvata lugens Stal.) and the Diversity of Its Natural Enemyin Highland Paddy Rice Field in the Village of Panyocokan, Ciwidey District, Bandung RegencyBrown lanthopper/BPH (Nilaparvata lugens Stal.) is a main pest of rice in the field. This researchwas aimed to study the population of BPH and the diversity of its natural enemy in highland paddyrice field. The survey was conducted in three paddy plots (15 m x 20 m) located in the village ofPanyocokan, Ciwidey District, Bandung Regency, West Java. The experiment was conducted in thegreenhouse of the Department of Plant Pests and Diseases, Faculty of Agriculture, UniversitasPadjadjaran. The samples of insects were collected systematically using yellow trap and net trap,and visually observed in each rice cluster. The number of BPH were recorded and accumulatedeach week. Fecundity, life cycle, and sex ratio of the new generation of BPH were observed in 3replications by using 1 pair of WBC on each replication. The result showed that the population ofBPH in the highland was below 10, which means that BPH population was still below theeconomic threshold and control threshold. Temperature, humidity, and rainfall did notsignificantly affect the BPH population. This was indicated by the regression analysis of eachtemperature (Y = 0.557-8.167x; R2 = 0.039; P = 0.465), humidity (Y = -0.077+ 9.112x; R2 = 0.045; P =0.428), and rainfall (Y = -0.118 + 3.412x; R2 = 0.136; P = 0.159). Natural enemy diversity indextended to fluctuate widely from low to moderate. In the temperature range from 21.1°C to 34.8°C,BPH could produce 127-207 new generation during its lifetime. BPH needed an average of 37.66days to produce a new generation. The ratio of male to female was 1.06 : 1.Keywords: population, brown planthopper, diversity, predator, highland paddy rice field, Ciwidey,BandungABSTRAKHama wereng batang cklat/WBC (Nilaparvata lugens Stal.) merupakan hama utama tanaman padi.Penelitian ini bertujuan untuk mempelajari populasi WBC dan keragaman musuh alaminya padatanaman padi sawah di dataran tinggi.
