EXAMINATION
& EXERCISES #1 FOR INSECT
POLLINATION (Contact)
GENERAL
PROBLEMS 1.
Define asexual reproduction in plants and list three methods by which
plants are asexually reproduced. 2.
Define self-pollination. 3. In
angiosperms (flowering plants) where do you find (a) he male (sperm cell
producing) plants and (b) the
Female (egg cell producing)
plants? 4.
Name four ways whereby plants attract insects for pollination. 5.
Give and example of each of the following: (a) Social flower, (b) Dioecious plant (sexes on separate
plants,
(c) Pinch-trap flower, (d)
Hymenopteran flower 6.
Wild bees have been successfully introduced from one country to
another for purposes of pollination.
Name
(a) The country of origin, (b)
the country of introduction, (c) the kind of wild bee. 7. In
most cases what is the main drawback to nesting sites accidentally created by
humans? 8.
What is the outstanding biological characteristic of all bees that
separates them from nearly all other insects? 9.
Name the four most important insect orders where members are
influential as pollinators. 10.
What are three ways whereby available populations of wild bees can be
used to best advantage for
pollination? 11. What
is the main objection to the use of Lepidoptera for pollination? 12.
Name three ways in which available populations of wild bees could be
used to best advantage for pollination. 13.
Briefly discuss ancient beekeeping as a business or otherwise. 14.
When and by whom was the first great step taken in the direction of
modern beekeeping? 15. Honeybees are poor pollinators when compared to many wild bees of
different families and genera. Then
why are honeybees so widely
used worldwide for pollinating agricultural crops? 16.
Comment on the returns from beekeeping and the approximate average
production per colony per year in
North America. 17.
With the cost of production and the returns in mind, how does
beekeeping compare with other agricultural
enterprises? 18.
What kind of bee races are deployed in beekeeping.? 19.
What place is given to the Italian race of honeybee? Name some of its desirable and some of its
undesirable
habits. 20. As
far as races of bees are concerned, on what does the progress of bee culture
depend? From the
standpoint of honey production what can be done to improve a bee
colony? 21. What can you say (briefly) of the ancestry of honeybees? 22.
What is the scientific name of the honeybee? Where does it rank in its
own order? What is the meaning of
the scientific name, as now
used? 23.
Why cannot honeybees live alone? What qualities of the honey bee
places it at the top of the list of bees and
perhaps of all insects? 24.
Name and ascribe the various casts of which a honeybee colony is
composed. In colonial life, what are the
functions of the respective
individual casts? 25.
Describe the nest of the honeybee. What is the relative position of
the normal brood comb, of honey and
brood respectively? 26.
Describe a honeybee queen cell.
Compare the queen with other members of the colony. Point out her
importance. Give an account of her chief functions in the hive. 27.
Discuss the subject: How Queens are produced. Name some of the most
important differential effects
produced on queen and workers larvae respectively, by the peculiar
treatment accorded each. 28. Briefly discuss the Drone honeybee. How he is produced; why is he
disqualified as a producer of nectar,
pollen, or wax; his ability to
defend himself, his mission in the colony and how he is qualified to perform
it. What importance is attached to the control of drone population in
a colony? 29.
Give the facts relative to the developmental stages of queens,
workers, and drones respectively. Briefly
mention the various duties of workers, showing how they are
structurally adapted for the special tasks
required of them. 30. What are the chief obstacles that have stood in the way of
honeybee stock improvement by controlled
mating? What steps have been taken to overcome them? 31. Mention one important
improvement that is being made in bees by scientific breeding. What modern
discovery or invention is making this possible? 32. What is the present extent of beekeeping in North America? What is the trend with respect to the
number
of colonies of bees per individual beekeeper, and the number of
individuals keeping bees? 33. Summarize the
subject: Home Methods of Queen Rearing. 34. Point out two or more
essential features of producing queen cells in which all four of the above
methods agree. 35. Describe a honeybee
Queen mating nucleus. 36. What conditions
through the years have obstructed the improvement of stock? What is now being
done to overcome this condition? 37. Briefly discuss
production and shipment of packaged bees. |
