ENTO 320 MOCK EXAMS 2025/2026 QUESTIONS WITH
ANSWERS RATED A+
✔✔Queens use this gland to mark their eggs and reduce egg removal. - ✔✔Dufours
✔✔Headless bees have lost their ability to walk and sting. - ✔✔False
✔✔In general, beekeepers can observe that a dark colored queen bee will have dark
sons (drones), but her daughters (workers) are often more variable. How might you
explain this? - ✔✔drones have only maternal genetics while daughters have paternal
component
✔✔The social structure of which member of Apoidea tends to break down once males
are produced? - ✔✔Bombini/Bumble Bees
✔✔It is sometimes helpful when trying to understand the functionality of a colony of
eusocial organisms to think of the colony as one collective, living unit. This is the
concept of the ________. - ✔✔
✔✔Worker ants have different jobs based on their morphological caste. - ✔✔True
✔✔Individuals of a "superorganism" are usually able to survive and flourish by
themselves as well. - ✔✔False
✔✔If you employ the concept of the superorganism, individuals in a eusocial group can
be compared to cells or tissues within an organism.
Based on your knowledge of honey bees, which of the following analogies does not
make sense? - ✔✔Foragers/Ovaries
✔✔A single gene is responsible for the differences demonstrated by high vs. low pollen
hoarding strains of bees. - ✔✔false
✔✔High pollen hoarding strains of bees begin foraging later in life than low pollen
strains. - ✔✔false
✔✔What characterizes the relationship between juvenile hormone and vitellogenin in
the worker honey bee? - ✔✔THE ANSWER IS NOT-
juvenile hormone increases the response to vitellogenin
**JH surpresses vitellogenin
, ✔✔According to the authors, what does the concept of the superorganism completely
fail to explain? - ✔✔the developmental evolution of this social structure at the genetic
level
✔✔Why would factors associated with female reproductive biology affect foraging
behavior in a solitary ancestor of the honey bee? - ✔✔to coordinate reproduction and
foraging for resources to provision offspring
✔✔What best describes the primary function of vitellogenin in a solitary female insect? -
✔✔THE ANSWER IS NOT-
responsible for female specific morphology
** honeybee vitellogenin is now
recognized as a behavioural affector protein that builds a direct connection between
worker
reproductive physiology and foraging behavioural control
**vitellogenin was used in worker brood-rearing behavior
✔✔Which of the following best describes the previous* consensus among researchers
about the effects of social evolution on the function of reproductive gene and endocrine
pathways of the sterile worker caste? - ✔✔sociality reduces the functionality of these
networks
✔✔According to the reproductive ground plan hypothesis, what have the reproductive
regulatory networks been co-opted for in the case of the worker caste of honey bees? -
✔✔adaptive behaviors associated with foraging division of labor
✔✔-low sucrose response threshold
-greater ovary development - ✔✔high pollen hoarding line
✔✔-higher likelihood of nectar collection
-moderate and stable adult vitellogenin titers - ✔✔low pollen hoarding line
✔✔According to the Reproductive Ground Plan Hypothesis, what type of worker bee
would be most analogous to a solitary insect in a reproductive stage? - ✔✔NOT- worker
with relatively low vitellogenin titers
✔✔The RGPH is supported in great part by a number of measurable differences
between lines of artificially selected bees. What specific characteristic was artificially
selected for to develop these lines of bees? - ✔✔NOT- juvenile hormone titers
** colony-level
pollen hoarding
**stored pollen
