Sampling/Monitoring Arthropod Pests and Their Natural Enemies

1. Methods of sampling include the following:

(a) Counting the number of arthropods on plant parts
(b) Fecal pellet collections
(c) Physical removal of arthropods on a white substrate
(d) Timed counts of life stages of arthropods
(e) The use of sex pheromone traps

2. The detection of the presence or absence of a key pest on a key host is the major objective of sampling; beneficial arthropods should also be noted.

3. A management decision will have to be made concerning the need to implement a particular control tactic.
