Diurnal patterns of adult activity of four orchard pests (Lepidoptera: Tortricidae) measured by timing trap and actograph.

Abstract: An aclograph using ultrasound was constructed to evaluate adult behavior of' lour tOI\"tricid moths: Cydia pomonella (L.l, Agryrotaenia citrano (Leonard), Pandemis pyl'llsana (Kearrott), and Chorislolle\"ra rosaceano (Harris). Studies were conducted to compare the timing of male and female moth activity in the adograph using simulated dusk and sunrise periods with the liming of male captures in pheromone-baited traps at 60­ min intervals. For all four species, the timing of acti\\'iLy measUl'cd for males and females in the adograph was similar to the liming of catch of male moths in the field. Peak periods of adult activity and male moth catch were 0-1 h after dusk for Cydia pomonella, 3-5 h after dusk for Argyrotaenia citrano, 0-2 h afler dusk for Charislancura rosaceana, and 0-1 after dusk for Pandemis pyrusana. For both sexes of all species, except female Chorl:sloneura rosacea,1/.n, activity levels of both sexes in the actograph increased allhe onset of sunrise. This was particularly pronounced for Cydio. pomonella. In the actogl'aph, females of Argyrotaelli.(l citrano. and Choristoneura rosaceallCl had an elevated level of activity prior to the simulated dusk period. Future studies with the actog'raph are planned to evaluate the effect of pheromone blend and concentration on the activity patterns of both sexes of these species.
