Insect cuticle penetration

Description:It is suggested that certain solvents increase the rate of penetration of contact insecticides through the insect cuticle: The influence of the physical properties of the solvents on carrier efficiency was investigated. It was found that a high carrier efficiency could be correlated with a high rate of penetration through beeswax, a high partition coefficient of the solvent between beeswax and water and a high solubility of insecticide in a solution of the solvent in water. Using Melophagus ovinus, the sheep ked, as test insect, it was found that certain organic solvents of diphenylamine, such as the cresols, benzyl alcohol and 4-methyl-cyclohexanol, greatly increase the rate of action of this insecticide.
