A range of methods is available for the control of insect pests. Each of these methods has its advantages and disadvantages and these must be balanced against each other in determining which (combination of) method(s) is most appropriate in a given instance. Some of these methods are spectacular but short-term and will be appropriate, for example, where massive outbreaks of pests are relatively sudden, yet unpredictable and temporary. Others are more slowly acting but relatively permanent in effect, and may be used for pests that are more or less permanent but whose populations are relatively stable.

Conway (1976) and Southwood (1977) proposed that pests can be arranged in a spectrum according to their "ecological strategies" and that the principal (best) method of control is based on their position in the spectrum (Table 24.3). At either end of the spectrum are the so-called "r pests" and "K pests," with the "intermediate pests" in between.
