This movie describes a series of experiments to examine female cues which induce male mate orientation of A. malasiaca. [See legend of the former movie (1) for details of this beetle]. The male finds and approaches the female with olfactory cues derived from her. Visual cues also act as synergists during such male mate orientation.
(00:00-00:03) Observation box: A plate lined with a paper sheet (21¡ß30 cm) was stood at 75¡ëin an acryl box (30 x 30 x 30 cm)
(00:04-00:13) Males straightly walked to upper side if nothing was put on the plate (playback speed: ¡ß2)
(00:14-00:27) Males also walked straightly upward when a black glass rod (female model) was fixed on the plate. (Play back speed: x 2)
(00:27-00:54) When the black model was treated with female extract, males showed orientation (tuned to the model without contact) and arrived to it.
(00:54-01:15) To the white and transparent model treated with the extract, males showed such responses less frequently than to the black model*.
Thus, males locate to females with olfactory cue derived from the females, and use visual cues of female as synergists. (Fukaya et al., 2004).
*Black, white and transparent models treated with 0.5 female equivalent of extract were orientated by 80% 30% and 25% of males respectively (Fukaya et al., 2004).
