1. A method of reducing risk of developing pesticide resistance in target mosquito populations is to:
Rotate use of different pesticide classes.
Apply larger pesticide doses.
Apply smaller pesticide doses more often.
Treat the source more often.
2. Another term for physical control is:
Environmental manipulation.
Regulatory mechanisms.
Civic responsibilities.
Integrated management.
3. The scientifically-planned control of mosquito populations through timely use of a variety of control strategies and methods is called:
Biological mosquito control.
Chemical mosquito control.
Physical mosquito control.
Integrated pest management.
4. An essential element of a successful adulticiding operation is the presence of:
Hot temperatures.
A slight wind of 12 mph or more.
A thermal inversion layer.
All of the above.
5. In vector control, the term IPM stands for:
Insect population monitoring.
Insecticides, pesticides, and mosquitocides.
International pesticide machinery
6. The primary mosquito problem associated with agricultural areas results from:
Sources created by overflowing streams.
Sources associated with crop irrigation.
Ponding of rainfall.
Residential sources around farm buildings.
7. Physical control in large lakes may be enhanced by:
Creating numerous small islands.
Keeping shoreline depths shallow.
Removing emergent vegetation.
8. The objectives of good physical control practices for mosquito abatement are to:
Prevent accumulation of water.
Prevent homeowner misuse of water.
Provide natural predators in salt marshes.
Use the least amount of pesticides.
9. The system of physical control most favored for mosquito control in coastal salt marshes where it can be used is:
Drainage.
Filling.
Circulation of tidewater.
Impoundment of water.
10. One of the most effective biological control methods for mosquitoes is:
Artificial bat colonies.
Construction of large bird houses.
Mosquito fish.
Mosquito-eating beetle larvae.
11. Which of the following types of worms have been tested as biological control organisms of mosquitoes:
Mermethid worms (Romanomermis).
Filarial worms (elephantiasis)
Earthworms.
Tomato fruit worms.
12. A possible advantage of chemical control of mosquitoes is:
The need for repeated doses over time.
Rapid control of mosquito populations.
Development of pesticide resistance.
The lack of any environmental hazards.
13. The unintentional movement of insecticides to non-target areas.
Temporal displacement.
Wide-fan spraying.
Drift.
Over-dosing.
14. The basic goal of mosquito control is to:
Eradicate a vector species.
Eliminate all mosquito larvae within a 10 mile radius of all cities and towns.
Eliminate all immature mosquitoes before they can emerge as adults.
Reduce the level of adult female mosquitoes of problem species to the point where the problem is reduced.
15. Which of the following pesticides are not considered biorational:
Methoprene.
Bacillus sphaericus.
Malathion.
Diflubenzuron (Dimilin)
