Despite of the economic importance of Circulifer haematoceps (Mulsant et Rey) (Hom., Cicadellidae) transmitting at least three serious plant pathogens, little is known about the seasonal flight and diurnal activity of this leafhopper. Circulifer haematoceps flight activity was monitored by yellow sticky traps in first and second planting of sesame. In addition, the results of the trap captures were compared with the direct D‐VAC sampling in one sesame field. The diurnal activity was monitored over three successive days, 28–30 August, and again on 15 September by yellow sticky traps that were changed every two hours for most of the day and replaced every half hour between 05.30 h and 07.30 h and 17.30 h and 19.30 h. The yellow‐trap sampling revealed consistent seasonal activity patterns associated with both the first and second crop, characterized by a secondary maximum within the first 30 days and an absolute maximum between day 52 and 73 after sowing. Males made up > 85% of the sticky‐trap catches while females were better represented in the D‐VAC collections (74%). The diel activity was greatest between 17.30 h and 19.30 h and most concentrated within a 30 min period just before sunset. Very few individuals were captured during hours of high light intensity and during the night. During the period of greatest activity only males were trapped.
