| First, we assessed whether N. cucumeris avoided odors of Orius that had been feeding on different diets, by means of an olfactometer. |
| A device called an olfactometer wafted the odours of each participant towards the mosquitoes. |
| Mosquito responses were favorable in the olfactometer, but the human hand still attracted the most. |
| In Y-tube olfactometer tests, tomato-strain mites showed a preference for tomato, while cucumber-strain mites showed no preference. |
| Predators were individually introduced into the olfactometer at the starting point on an iron wire, which was positioned in the center of the glass tube. |
