Table 2 Olfactometer attraction assays. Mean numbers (±SE) of Ph. papatasi females in the treatment, middle, and control chambers of the olfactometers and percent flies responding (Total number of flies at both the treatment and control chambers divided by total flies used) for the different substrate types. Rearing media of 2^nd/3^rd and 4^th/pupa (bolded) induced highest attraction
