Abstract

Due to increasing attacks by Nysius cymoides, False Chinch Bug (FCB), in the canola fields of Iran, attempts have been made on its different control measures. Use of attractants might be a promising method in this relation. Behavioral effect of a synthesized isothiocyanate attractant was studied on FCB adults under laboratory condition. Ethyl 4-isothiocyanatobutyrate (ETCB) was synthesized via two-step reaction sequences from starting material of 4-aminobutyric acid with exposure to HCl gas, following the treatment of resulting ester with 1,1`-thiocarbonyldiimidazole. This technique is a newly modified procedure whose comparison with the commonly used technique is discussed. Although the synthetic attracted both sexes in a two-choice pitfall olfactometer, it was more efficient on the female FCBs.
