Microbial metabolites with insecticidal properties.
A screen of fungi for insecticidal activity revealed the ability of Aspergillus versicolor to make versimide, methyl-alpha-(methylsuccinimido)acrylate, a novel contact insecticide. The larvicidal activities of Alternaria tenuis and Fusarium lateritium were found to be due to tenuazonic acid and diacetoxyscirpenol, respectively. Thiolutin, cycloheximide, rubratoxin, patulin, trichothecin, an act...
متن کاملTri-Trophic Insecticidal Effects of African Plants against Cabbage Pests
Botanical insecticides are increasingly attracting research attention as they offer novel modes of action that may provide effective control of pests that have already developed resistance to conventional insecticides. They potentially offer cost-effective pest control to smallholder farmers in developing countries if highly active extracts can be prepared simply from readily available plants. ...
متن کاملMolecular Characterization of a Fungus Producing Membrane Active Metabolite and Analysis of the Produced Secondary Metabolite
Background: The majority of studies on soil Aspergillus concern the isolation and characterization of the antimicrobial compounds produced by this organism. Our previous studies indicated an isolated Aspergillus strain soil to be of interest, and this subject is further investigated here. Method: Soil samples of various locations in Iran were collected. Extract from Aspergillus sp. culture was...
متن کاملThuringiensin: A Thermostable Secondary Metabolite from Bacillus thuringiensis with Insecticidal Activity against a Wide Range of Insects
Thuringiensin (Thu), also known as β-exotoxin, is a thermostable secondary metabolite secreted by Bacillus thuringiensis. It has insecticidal activity against a wide range of insects, including species belonging to the orders Diptera, Coleoptera, Lepidoptera, Hymenoptera, Orthoptera, and Isoptera, and several nematode species. The chemical formula of Thu is C22H32O19N5P, and it is composed of a...
متن کاملA novel fungal metabolite with beneficial properties for agricultural applications.
Trichoderma are ubiquitous soil fungi that include species widely used as biocontrol agents in agriculture. Many isolates are known to secrete several secondary metabolites with different biological activities towards plants and other microbes. Harzianic acid (HA) is a T. harzianum metabolite able to promote plant growth and strongly bind iron. In this work, we isolated from the culture filtrat...
