Potential of Essential Oil-Based Anticholinesterase Insecticides against Anopheles Vectors: A Review

open access: yes, 2022
The insect nervous system is critical for its functional integrity. The cholinergic system, of which acetylcholinesterase (AChE) is a key enzyme, is essential to the Anopheles (consisting of major malaria vector species) nervous system.

Environmental effects of insecticides on non target predator and parasitoid insects

open access: yes, 2009
When considering how insecticides impact beneficial insects, in addition to direct mortality, we need to assess sublethal effects on population numbers which reduce the efficacy of the predators and parasitoids in reducing pest insects.

Mode of action of plant-derived natural insecticides

open access: yes, 2014
Most of the chemical insecticides are neurotoxic, acting on targets in the central nervous system such as the membrane ion channels (DDT, pyrethroids), the enzyme acetylcholinesterase (organophosphate, carbamate), and the receptors of neurotransmitters ...

Optimising the Eco‐Friendly Extraction of Carotenoids From Gac Fruit: A Sustainable Solution for Natural Red Food Colourants

open access: yesFood Chemistry International, EarlyView.
Gac fruit's high carotenoid content, especially in the aril, makes it an excellent natural red pigment source for food applications, offering a safer alternative to synthetic dyes. Ethanol extraction achieved the highest overall pigment recovery (89.53%), whereas ethyl lactate extraction yielded the highest levels of total carotenoids, β‐carotene ...
