All tests were carried out with a single Cs male with perfumed and/or non-perfumed desat1 females, either in choice or in no-choice experiments (see Table 1). The total female and male progenies of each mated female were pooled during the 8 days following the first day of adult eclosion.
The total progeny and sex ratio represent the sum and the ratio of female and male progenies.
Values are means ± s.e.m.
