(Please choose 5 test questions from them)
1.Insects are the majority vectors of arthropod-borne pathogens, such as
Aphididae, Aleyrodidae, Psyllidae, Cicadellidae, Delphacidae and
Cercopidae. Please describe the transmission pathway (mechanism) of
plant pathogens by vectors. (please give one example for description)
2.The modes of action (MOA) of organochlorines, organophosphates,
synthetic pyrethroids, nicotinoids, and insect growth regulators (IGRs) are
different from each other. Please describe the superiorities and defects of
them.
3.Please propose one Integrated Pest Management (IPM)-based Farming
System for a citrus orchard. (you may give an example of any else crop)
4.What is the mode of action (infection process) of nuclearpolyhedrosis
virus (NPV)? Please give an example of NPV for controlling the pest and
describe the cautions about application.
5.Cultural techniques comprise those that involve the manipulation of an
agroecosystem in order to decrease the success of pest species within it.
Please describe the relative techniques for improving plant health.
6.The three ways in which biocontrol agents can be used, such as classical
biological control, augmentation/inoculation, and habitat manipulation. 1).
How to choose the most appropriate way for the pest control in different
situations? 2). Please give a schematic of a stepwise procedure for
setting up a classical biological control program.
101/01Ⅱ
1. Explain the interactions between insect vectors, plant viruses and their
hostplants on transmitting insect-borne plant diseases, and describe how to
manage the disease transmission in the fields.(15%)
2. Give an example to explain how to enhance microbial control effect in
pest management in the fields.(10%)
