Figure 1. Insect Behaviour under different barometric pressure conditions.

Figure 1

Frequency of different behaviours exhibited by three different insect species when subjected to stable, decreasing and increasing barometric pressure. A: The proportion of active D. speciosa males in Y-tube olfactometer to sex pheromone stimuli; B: The proportion of P. unipuncta and M. euphorbiae females exhibiting calling behaviour; C: The proportion of P. unipuncta and M. euphorbiae couples mating. **Indicates significant difference among treatments at 1%.
