Quiz 3 - Version B


 1.  Dorsal ocelli are found only in the larvae of holometabolous

 2.  If an insect's legs are removed, it may lose its sense of 

 3.  Exogenous rhythms persist even in the absence of entrainment
     cues from the environment.

 4.  The frontal nerves run from the tritocerebrum to the
     subesophageal ganglion.

 5.  Crepuscular insects are most active between dawn and dusk.

Multiple Choice:

 6.  Compared to most learned behaviors, instinctive (innate)
     behavior is:
     A.  More stereotyped
     B.  Less complex
     C.  Not subject to evolutionary change
     D.  All of these

 7.  When laying eggs, a female insect returns to her larval host

     B.  Maxillary palps             D.  Frons
 9.  In insects with dichromatic (2 pigment) color vision, maximum
     color discrimination is in the range from:
     A.  Red to green                C.  UV to green
     B.  Yellow to blue              D.  Bee violet to bee purple

10.  The mandibular gland substance of the queen honey bee inhibits
     ovarian development among worker bees in the same hive.  This
     is an example of a(n):
     A.  Allomone                    C.  Synomone
     B.  Pheromone                   D.  Kairomone

11.  If a nerve impulse started in the tritocerebrum and passed
     through the stomodeal nervous system until it reached the
     heart, it would NOT pass through the:
     A.  Recurrent nerve             C.  Subesophageal ganglion
     B.  Frontal nerve               D.  Hypocerebral ganglion

     B.  Wind speed                  D.  Water vapor

13.  Stridulation is a method of producing sound by:
     A.  Vibrating the wings.
     B.  Vibrating a resonant membrane.
     C.  Striking the substrate.
     D.  Rubbing body parts together.
