FIGURE 6 in Olfactory Responses Of Phytoseiulus Persimilis To Rose Plants With Or Without Prey Or Competitors

FIGURE 6: In the Y-tube olfactometer, Phytoseiulus persimilis were offered a choice between odours from clean air in one arm vs odours from clean rose plants in the other (a,c) and between clean rose plants in one arm vs odours from both Phytoseiulus persimilis and Tetranychus urticae in the other (b, d). The population of Phytoseiulus persimilis used had been exposed to rose plants with T. urticae for 24h (a – b) or during 6 months (c – d). P values of the G test for each replicate are given next to each bar; overall P values are given in Table 1.
