Question 1

innate behavior

Answer 1

behavior that’s genetically hardwired in an organism and can be performed in response to a cue without prior experience

Question 2

learned behavior

Answer 2

one that an organism develops as a result of experience

Question 3

ganglionic center

Answer 3

It is the assemblage of ganglia and the connections between them that form the “backbone” of the insect nervous system.

Question 4

olfactory receptors

Answer 4

odorant receptors that are responsible for the detection of odorants, allowing for a sense of smell

Question 5

ventral nerve cord

Answer 5

a major structure of the invertebrate central nervous system

Question 6

taxis

Answer 6

a form of innate behavior in which the insect changes body position either toward or away from the stimulus.

Question 7

pheromones

Answer 7

chemicals produced in exocrine glands and released to the outside of the body to promote communication between members of the same species.

Question 8

allelochemical

Answer 8

semiochemicals used for interspecific communication

Question 9

kairomone

Answer 9

a type of allelochemical by which the emitter may or may not be harmed by the chemical released but the receiver usually benefits.

Question 10

intraspecific communication

Answer 10

The interchange or transmission of thoughts, opinions, or information by speech, writing, or signs from one member of a species to another member of the same species.

Question 11

aposematic coloration

Answer 11

or warning, coloration is used by noxious organisms to signal their unprofitability to potential predators

Question 12

social language

Answer 12

any of numerous species of insects that live in colonies and manifest three characteristics: group integration, division of labor, and overlap of generations.

Question 13

allomone

Answer 13

chemical substances produced and released by an individual of one species that is harmful to the receiver

Question 14

mimesis

body coloration that allows insects to appear as a natural object in the environment.

Question 15

thanosis

Answer 15

playing dead as a defensive strategy

Question 16

sequestration

Question 19

stress

Answer 19

response to a changing environment or stimuli.

Question 20

stressor

Answer 20

stimuli that cause an organism to deviate from the homeostatic condition for long enough that normal physiology is altered.

Question 21

heat shock

Answer 21

response to a rapid elevation in temperature

Question 22

environmental token

Answer 22

environmental cues that trigger behavioral and physiological mechanisms to turn on or off.

Question 23

diapause

Answer 23

periods of metabolic suppression

Question 24

seasonality

Answer 24

changes that occur in the insect’s environment throughout the course of a year
