Figure 4.

The six-arm olfactometer test for the repellency of mated females and of unmated males in the two parasitoid species, C. glomerata (A,C) and C. marginiventris (B,D,E), immediately (A,B), about 18 hours (C,D) and about 40 hours (E) after females had mated, respectively. The proportion of wasps that showed no response, i.e., that did not choose an arm, is given in red in the pie chart, supplemented with the absolute numbers of wasps. Statistical differences (p < 0.05) are indicated with different letters above the bars.
