BACKGROUNDS In insects, cholesterol is one of the membrane components in cells and a precursor of ecdysteroid biosynthesis. Because insects lack two key enzymes, squalene synthase and lanosterol synthase, in the cholesterol biosynthesis pathway, they cannot autonomously synthesize cholesterol de novo from simple compounds and therefore have to obtain sterols from their diet. Sterol carrier prot...

Abstract. Damiri N, Pujiastuti Y, Mulawarman, Astuti DT, Afriani SR, Rahim SE. 2022. Short Communication: Biological control agent for Spodoptera litura on vegetable plants. Biodiversitas 23: 2609-2613. This study aimed to assess the population dynamics of Bacillus thuringiensis and its potency as a bio-agent against litura.

Low long bean productivity is one of the impacts S. litura. Farmers often rely on chemical fertilizers to control population litura so that this method can leave residues in growing media. Therefore, an effort overcome problem use natural pesticides from beluntas leaves (P. indica), which produce secondary metabolites. This study aimed determine effect ethanol extract indica) mortality second i...

Cadmium is a potentially toxic and carcinogenic nonessential heavy metal. This study investigated Cd accumulation along the soil-plant (Amaranthus hypochondriacus L.)-insect (Prodenia litura) food chain and the detoxification strategies at different trophic levels. A. hypochondriacus leaves could accumulate high levels of Cd from polluted soil. The Cd concentration in P. litura larvae increased...

Armyworm (Spodoptera litura F.) is one of the important pests on plant mustard greens. The purpose this research to get type pesticide that effective gives highest effect mortality and intensity attack armyworm in (Brassica juncea L.). method used experimental while design experiment was Complete Random Design (RAL) a single factor for observation Randomized block (RAK) consisting 8 treatments ...

Spodoptera litura (F.) is one of most important defoliators occurring in Uttarakhand causing significant losses to crops. Its occurrence the different regions was explored through survey conducted from 2018-2020. Environmental variables for current and future climatic scenario were used Maxent software Species Distribution Modelling, QGIS 3.22 map processing. These analyses results revealed tha...

Spodoptera litura dapat menyebabkan kehilangan hasil hingga 80% bahkan gagal panen. Nuclear Polyhedrosis Virus merupakan agensi hayati dari kelompok patogen serangga famili Baculoviridae yang banyak digunakan sebagai agens dan (SlNPV) salah satu pemanfaatan NPV efektif dalam mengendalikan litura. Kendala penggunaan SlNPV yaitu tidak tahan terhadap sinar matahari sehingga perlu bahan pelindung a...

The tobacco caterpillar, Spodoptera litura F., is one of the most devastating, cosmopolitan polyphagous pests affecting major crops that significantly impact agricultural productivity. present study aimed to evaluate toxicological effect seed extract medicinal plant, Annona squamosa L. and histological on midgut under laboratory conditions. crude methanolic A. was tested against third instar la...

A vast array of herbivorous arthropods live with symbiotic microorganisms. However, little is known about the nature and functional mechanism bacterial effects on plant defense responses towards herbivores. We explored role microbes present in extracts oral secretion (OS) isolated from larvae Spodoptera litura, a generalist herbivore, phytohormone signaling-dependent Arabidopsis thaliana (Arabi...
