Synthetic And. consist generally of three groups: chlorinated hydrocarbons (see), organophosphorous connections (see) and carbamates (see. Carbamic connections ). To vegetable, belong pyrethroids (see) and some other substances having limited use.
Depending on objects against which are applied And., they are called acaricides if are used against mites, larvicides — against maggots, by egg-killers — against eggs of insects and mites.
