Interpretive Summary:

Technical Abstract: Ecofriendly and sustainable alternatives to chemical pesticides are needed to effectively control mosquitoes and reduce mosquito-borne pathogens infectious to humans and animals. Three major chemical products of enzymatic degradation of mustard seeds; allyl isothiocyanate, benzyl isothiocyanate and 4-hydroxybenzyl isothiocyanate were evaluated for toxicity (LC50) to larvae of the yellow fever mosquito, Aedes aegypti. All three isothiocyanates tested were toxic to Ae. aegypti larvae and their LC50s differed significantly from each other. Benzyl isothiocyanate had an LC50 value of 5.29 ppm compared with LC50 values of 19.35 for allyl isothiocyanate and 55.41 ppm for 4-hydroxybenzyl isothiocyanate. These results demonstrate the potential for isothiocyanates as promising ecofriendly larvicides for mosquito control.
