Abstract. Listihani L, Yuniti IGAD, Ariati PEP, Pandawani NP, Selangga DGW, Temaja IGRM, Wirya GNAS, Sudiarta IP. 2023. Beneficial interaction between rice stunt virus and its insect vector Nilaparvata lugens Stal based on life table. Biodiversitas 24: 4690-4698. The brown planthopper (Nilaparvata lugens) causes direct and indirect damage as a stunting virus vector in rice. Insect vectors and viruses are closely related with respect to disease transmission to host plants. Thus, this research aimed to determine the specific relationship between a virus and its insect vector on the biology and demography statistics of viruliferous brown planthopper (BPH). Research method included the propagation of N. lugens and stunt virus inoculum, the observation of cohort, stadia duration and egg survival rates, imago life span, and N. lugens life table. The BPH life table was arranged with the jackknife method for two treatments: plants infected by stunt virus and healthy plants. The research result showed that plants infected by stunt virus can shorten the BPH nymphal development stage from instar 2 to instar 5, life cycle, preoviposition period, and double time. Plants infected by stunt virus did not influence the BPH hatching pattern but influenced the total number of hatching eggs. The next BPH generation of stunt virus inflected plants increased 29.51 times more from the previous generation, while on healthy plants, the next BPH generation only increased 27.51 times. Virus-infected plants generally appeared to be superior quality hosts for vectors compared to uninfected plants, thus enhancing vector life table and virus spread.

Abstract

Tanaman buah salju (Inga sp.) merupakan spesies introduksi yang melimpah di kawasan Bedugul, Bali, namun informasi mengenai kandungan fitokimianya masih sangat terbatas. Penelitian ini bertujuan untuk menganalisis kandungan senyawa bioaktif daun tanaman buah salju dari kawasan Bedugul, Bali. Analisis fitokimia dilakukan melalui maserasi menggunakan tiga pelarut dengan kepolarannya berbeda dengan perbandingan 2:1:1 (n-heksan, etil asetat, dan etanol 96%), kemudian dianalisis menggunakan instrumen Kromatografi Gas-Spektrometri Massa Shimadzu QP2010 SE dengan kolom kapiler Rtx-5MS. Analisis Kromatografi Gas-Spektrometri Massa berhasil mengidentifikasi 20 puncak kromatogram pada ekstrak daun tanaman buah salju dari kawasan Bedugul. Senyawa dengan kelimpahan tertinggi adalah metil risinoleat (methyl ricinoleate) dengan area sebesar 44,83%, diikuti oleh trifenilfosfin oksida (11,07%), heneikosana total (11,47%), eikosana total (7,11%), dan metil oleat (6,54%). Berdasarkan komposisi kimianya, senyawa-senyawa tersebut terklasifikasi ke dalam kelompok metil ester asam lemak (56,59%), hidrokarbon alifatik (20,11%), dan terpenoid (2,01%). Total senyawa yang berpotensi bioaktif mencapai 61,52% dari total ekstrak. Ekstrak daun tanaman buah salju dari kawasan Bedugul memiliki profil fitokimia yang kaya dengan berbagai potensi biologis, meliputi potensi antiinflamasi yang kuat melalui sinergi metil risinoleat (44,83%), sitral/neral (2,01%), dan asam lemak tak jenuh; potensi antimikroba dan antijamur berspektrum luas; potensi anti-biofilm melalui pentadekanal (1,08%) dan sitral/neral; serta potensi sebagai bahan baku industri oleokimia.
