Question | Answer |
---|---|
Pest Surveillance | The watch kept on a pest for the purpose of decision making |
Insect pest survey | A detailed collection of insect population information at a particular time in a given area |
Sampling Unit | A proportion of the habitable space from which insect counts are taken |
A Sample (in surveying for insect pests) | A group of sampling units |
Sampling Universe | The habitat in which the population occurs |
Sampling Technique | The method used to collect information from a single sampling unit |
Sampling Program | The procedure that employs the sampling technique to obtain a sample and make a density estimate |
List three insect activities detected and documented by pest surveillance | Crop invasion d. Feeding b. Long-range migration e. Reproduction c. Local movement |
List three ways to determine insect sampling units | Insects per unit surface area b. Sweep nets are used making contact with only a portion of the plant being swept c. Insect light traps |
Sampling Programs direct how a sample is to be taken, and include four parameters. Name two | Insect stage to sample c. Spatial pattern to obtain sampling units b. Sampling-unit number d. Timing of samples |
The two types of sampling programs are | Extensive programs b. Intensive programs |
When using in situ counts, for any sampling technique one must also assess two other things: | The state of the plant b. Density of the sampling units present |
The two basic requirements of insect trapping for sampling are | The insects must move b. The trap must hold the captured insects |
The design of an insect sampling program involves at least four basic dimensions: | a. Insect stage to sample b. Number of sampling units to take c. Time to sample d. Pattern of sampling |
a. Insect stage to sample b. Number of sampling units to take c. Time to sample d. Pattern of sampling | Light b. A shape attractive to insects |
Soil is often sampled for insects by one of the following methods (list four) | Berlese funnels b. Sieving c. Washing d. Floatation |
