The acoustical receptors are destroyed on a population of larvae and rates of wasp predation are measured on the "deaf” larvae and on a population of normal larvae. Based on the curve in the figure and on the concept that animals possess sensory mechanisms that enhance survival, one could correctly predict which of the following?

#Unit 10. Ecological Principles

Predation intensity on normal and "deaf" larvae would not differ because wasps hunt visually and both larval populations would be equally visible.
Predation intensity would be greater on "deaf" larvae because the wasps could approach more closely before being detected and there would be less time for escape.
Predation intensity would be greater on the normal larvae because they are attracted to the wasp buzz.
Predation intensity on normal and on “deaf" larvae would not differ because the larvae are too slow to escape the approaching wasp.
