the third One ml volume of each type of essential oils was used per test. Ten (10) males and 10 female B. cucurbitae were tested alternatively – one at a time at the center of the
olfactometer and their behaviour recorded for 10 min using a hand timer. After a series of five males/females, the odour sources were connected to the opposite arm of the olfactometer to correct for any unforeseen asymmetry in the experimental set-up. Each experiment was
repeated 3 times on the same day.
