Daftar Isi:
- Beluntas adalah salah satu tumbuhan yang berpotensi dikembangkan menjadi pestisida nabati, karena mengandung asam fenolik, flavonoid, alkanoid, saponin, tanin dan terpenoid. Senyawa metabolit sekunder tersebut dapat memberikan efek mortalitas terhadap hama. Penelitian ini bertujuan untuk mengetahui efektivitas daun beluntas terhadap mortalitas S. litura. Metode uji yang digunakan dalam penelitian ini adalah metode celup daun terdiri dari enam perlakuan dan diulang sebanyak lima kali. Parameter yang diamati adalah mortalitas S. litura pada fase larva, pupa, dan imago. Hasil Pengamatan menunjukkan mortalitas tertinggi terdapat pada dosis 90 gram basah/500 ml air sebesar 25 individu. Pengamatan dilanjutkan untuk larva yang masih hidup yaitu mortalitas larva prapupa tertinggi sebesar 19 individu pada dosis 45 gram basah/500 ml air, mortalitas pupa sebanyak 15 individu pada perlakuan kontrol, dan sisa pupa yang menghasilkan imago pada perlakuan kontrol sebanyak 2 ekor.
- Beluntas is one of the plants that have the potential to be developed into a botanical pesticide, because it contains phenolic acids, flavonoids, alkaloids, saponins, tannins, and terpenoids. These secondary metabolite compounds can have a mortality effect on pests. This study aims to determine the effectiveness of beluntas leaves on Spodoptera litura mortality. The test method used in this research was the leaf dipping method, consisting of six treatments and five times repeated. The parameters observed were the mortality of Spodoptera litura in the larval, pupal, and imago phases. Observation showed that the highest mortality was at a dose of 90 grams wet/500 ml water for 25 individuals. Observation continued for surviving larvae namely, the high mortality pre-pupa larvae of 19 individuals at a dose of 45 grams wet/500 ml water, pupa mortality of 15 individuals in the control treatment, and the remaining pupae that produced imago in the control treatment as many as 2 heads.
