Abstract：Objective To investigate the behavioral response of Blattella germanica to 16 plant derived compounds,and screen plant derived monomeric compounds that have attractant activity.Methods The electroantennography(EAG)and behavioral response of B.germanica were measured using an antennal potential meter,square box test,and four-arm olfactometer.SPSS 27.0 software was used to analyze the data.Results B.germanica showed certain electroantennographic responses to 16 compounds.Male and female adults had higher EAG values to HT-aldehyde 2,citral,HT-ester 3,and anisaldehyde.Different genders responded differently to the same compound,with a statistically significant difference in EAG response values to Ht-aldehyde 2 between male and female adults.Female adults had the highest EAG response value to anisaldehyde(113.27%),while male adults had the highest EAG response value to aromatic alcohol(100.00%).The comprehensive results of behavioral tests showed that HT-aldehyde 2 had better attraction to B.germanica,followed by HT-ester 3.The attractiveness of HT-aldehyde 2 in the square box test and the four-arm olfactometer were 37.5%and 32.67%,and the attractiveness of HT-ester 3 were 16.67%and 31.00%,respectively.Conclusion HT-aldehyde 2 can be used as formulations for attractants of B.germanica.
