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
  1. Predation intensity on  normal  and  "deaf"  larvae  would  not  differ  because  wasps  hunt  visually  and  both larval populations would be equally visible.
  2. 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.
  3. Predation intensity would be greater on the normal larvae because they are attracted to the wasp buzz.
  4. Predation intensity on normal and on “deaf"  larvae  would  not  differ  because the  larvae  are  too  slow  to escape the approaching wasp.
