    • Esters derived from fatty acids and juvenoid alcohols of the general formula (I), in which X means the oxygen atom or the NH group, Y means the NH group or the oxygen atom, R means methyl, ethyl, 1-propyl, 2-methylethyl or propargyl and R' means saturated or unsaturated alkyl with 4 to 22 carbon atoms. Esters derived from fatty acids and juvenoid alcohols are produced by a reaction of a juvenoid alcohol of the general formula (II), in which X means the oxygen atom or the NH group, Y means the NH group or the oxygen atom and R means methyl, ethyl, 1-propyl, 2-methylethyl or propargyl with a fatty acid chloride of the general formula (III): R'COC1 in which R' means saturated or unsaturated alkyl with 4 to 22 carbon atoms, under the continuous stirring, at 0 to 70 °C, using a convenient solvent, as toluene, xylene or benzene and under the presence of a base catalyst, as triethylamine, pyridine or quinoline. The compounds claimed in the Claim 1 of the general formula (I) are applied for the insect population density control.
