The brown planthopper (Nilaparvata lugens) attack and its genetic diversity on rice in Bali, Indonesia

Abstract. Listihani L, Ariati PEP, Yuniti IGAD, Selangga DGW. 2022. The brown planthopper (Nilaparvata lugens) attack and its genetic diversity on rice in Bali, Indonesia. Biodiversitas 23: 4696-4704. is an important pest crops of BPH isolates western Indonesia has been extensively reported, whereas eastern have not reported. This research aims to analyze evaluate the attack's intensity Bali plants. method used was observation percentage, population dynamics, intensity, 9 districts (Badung, Gianyar, Klungkung, Bangli, Karangasem, Tabanan, Denpasar City, Buleleng, Jembrana). Molecular identification carried out N. lugens DNA mtCOI fragment. attacks >50% were found Jembrana, Badung. primarily Ciherang IR-64 varieties Badung Regency, with 43.67 per hill. In general, grown all locations susceptible BPH, such as Ciherang, IR-64, Inpari 32, Situbagendit. varieties, highest average value reached 30%. sequence isolate from Jembrana showed nucleotide amino acid homology FSD-034 Pakistan (MK301229) biotype Y 99.5 -99.74% 100%, respectively. study plants for first time reported that Rice Situbagendit previously resistant are BPH.
