ABSTRACT
Electrophysiological responses of adult males and females of C. carnea to commonly occurring plant volatiles were recorded using the electroantennogram technique. Responses to 28 volatiles evaluated indicate that both depolarization and recovery to the baseline were rapid in females compared to males. Normalized EAG responses relative to the standard, trans-caryophyllene reveal significant differences between the chemicals as also between the sexes. The response of males to several of the compounds, particularly the terpenoids was higher than females. The pooled averages to the different classes of chemical compounds reveal greater response for fatty acid derivatives and terpenoids, particularly the oxygenated monoterpenes and the sesquiterpenes. These findings are discussed in relation to volatiles released in the cotton ecosystem.
