Some parasitoid flies respond to acoustic stimuli from crickets. Once the host is located, these flies lay their larvae on these insects. The maggots burrow into the bodies of crickets *** them. The graph depicts the tuning curves of parasitoid fly & cricket. In the accompanying figure, "c" indicates frequency versus intensity spectrum of cricket song.

State whether each of the following statements is true (T) or false (F).

a. The parasitoid species would exhibit the call of very similar frequency distribution as that of cricket. ____

b. The tympanic membrane & associated receptors that respond to frequencies lower than 4 & greater than 8 will be selected in the course of evolution. ____

c. The frequency of best sensitivity **** in the range of 5-8KHz for a parasitoid fly. ____

d. Mechanical filtering for narrow band hearing is more conspicuous in fly "X" than in fly "Y".____

e. "X" is likely to represent the response of a female predator and "Y" of a male prey insect. ____
