Abstract
Several benzyl-1,3-benzodioxole analogues have been reported to be sterilants for different diptera and a lepidopteran. We investigated the effect of 5-methoxy-6-(1-(4-methoxyphenyl)ethyl)-1,3-benzodioxole (J2710) on the coleopteran Leptinorarsa decemlineata (Say), the Colorado potato beetle, by feeding larvae potato leaves dipped in different concentrations of this compound. Larvae stopped feeding and died at concentrations >50 ppm. At 25 ppm, most were unable to pupateand died as prepupae. Feeding activity in newly emerged beetles was affected at concentrations >100 ppm, and complete mortality occurred at >250 ppm. Reduction of egg hatch, however, occurred atconcentrations as low as 10 ppm.
