Question

• Mechanical stimulation on the plants had an negative indirect influence on aphid reproduction.

How does wind induced stress in plants indirectly affect the reproductive capabilities of insects that feed on these plants?

• Direct wind also indirectly affected the aphids’ fecundity negatively over the course of the experiment.

Introduction • The effects of wind are understudied in insects, but can have many important impacts on prairie and agricultural systems, especially with wind speeds being predicted to further decrease due to climate change [5]. • Direct exposure to wind has been shown to alter insect dispersion [2] as well as insect herbivore feeding behavior [3].

• Density of plants in experiment 2 did not have a significant effect on aphid performance.

Discussion Fig. 1 Number of juvenile aphids per adult on the third day after infestation. Aphids on plants that received the touch treatment had significantly less babies. Anova F1, 184=14.06, p
