Sigillins from Springtails Are Potent Natural Insecticides
Journal of Natural Products, 2020Sigillins are highly chlorinated natural products from the springtail Ceratophysella sigillata (Collembola) that are used to deter arthropod predators. We report here the isolation and structure elucidation of sigillin F, a hydrogenated benzopyranone compound bearing two trichloromethyl groups, and the synthesis of trideoxysigillin (8), a non-natural ...

Modulation of membrane physical properties by natural insecticidal ketones
Biophysical Chemistry, 2021The insecticidal activity of Mentha oil and its main components has been tested and established for various insects/pests. Several mint ketones have demonstrated to act on GABAA receptors (GABAA-R), a transmembrane channel target of several important insecticides whose activity can be modulated by surface-active compounds and by changes in the physical

PHOTOTOXINS AS INSECTICIDES AND NATURAL PLANT DEFENCES
Memoirs of the Entomological Society of Canada, 1991AbstractThe thiophenes alpha-terthienyl and methyl-alpha-terthienyl are found in many species of the family Asteraceae and are highly phototoxic to mosquito larvae. These compounds and a synthetic analogue, cyano-alpha-terthienyl, controlled Aedes intrudens Dyar (Diptera: Culicidae) larvae at application rates between 10 and 40 g per hectare in field ...

Risks From Natural Versus Synthetic Insecticides
Annual Review of Entomology, 1994For centuries humans have used natural insecticides to combat insect pests that compete for our food and fiber or that affect public health. Some of these compounds were plant extracts or plant parts, others were mined from the earth. In the twentieth century synthetic insecticides have replaced natural ones as the standard means of controlling ...

Insecticidal organophosphates: Nature made them first
Experientia, 1987Out of the three most important classes of synthetic insecticides only the carbamates and pyrethroids were known to have ancestors in nature. Now two organophosphates (which are quite good insecticides and very potent acetylcholinesterase inhibitors, e.g. comparable to carbofuran) have been isolated fromStreptomyces antibioticus strain DSM 1951.

Natural Insecticidal Proteins and Their Potential in Future IPM
2021Increasing population and global food security is the foremost challenge for this century. Insect pests cause substantial damage to our crops by direct as well as indirect means such as vectoring plant viruses. Introduction of Bacillus thuringiensis originated toxins, namely, cry toxins, in the crop plants that showed significant resistance to insect ...

Insecticide Resistance in Natural Enemies
2016Pesticide resistance in pests has severe negative consequences but can be used as a positive trait for natural enemies as an opportunity to improve the simultaneous use of two very valuable tools in pest management: chemical and biological control. Biological control adoption is limited in some areas, crops, or seasons due to the imperative use of ...
