Single choice behavioural responses of the lesser grain borer Rhyzopertha dominica (Coleoptera: Bostrichdae) to host and non-hosts plant volatiles was studied in a four-choice airflow olfactometer in the laboratory. The host plants odour sources were 30 g maize seeds and 30 g winter wheat kernels, while the non-hosts plant odour sources were 30 g dried Piperguineense and 30 g dried Monodora myristica seeds, respectively. Also 10% (w/w) of each non-host plant was incorporated with host plant grains and tested against R. dominica male and female adults. Results showed that both male and female adult R.dominica were significantly (p<0.001) repelled by P. guineense and M. myristica alone and also when 10% (w/w) of these plant seeds were incorporated with 30 g maize and winter grains, respectively. Both sexes also significantly (p<0.0001) preferred maize and winter wheat seeds to the control in the mean time spent and the number of entries made to their odour zones.
