Allomone
- A chemical substance, produced or acquired by an organism, which, when it contacts an individual of another species in the naturl context, evokes in the receiver a behavioural or physiological reaction adaptively favorable to the emitter; cf. kairomone.
Antifeedant
- A natural or synthetic chemical substance which acts either to inhibit the stimulation of gustatory receptors which normally recognize suitable food, or to stimulate receptors which elicit a negative response to deterrent chemicals.
Biological control
- Biological pests suppression in its narrow, classical sense, usually restricted to the introduction, by man, of parasitoids, predators, and / or pathogenic microorganisms to suppress populations of plant or animal pests; cf. biological insect pest suppression, natural control.
Integrated pest suppression
- An approach to compatible utilization of all available forms of pest suppression, including mechanical, biological, chemical, and natural control, in a systematic fashion, with the primary goal of safe, effective, and economical pest population reduction. It may be directed at a single important pest species by combining a variety of measures against the species, or at a complex of pests, integrating the individual protective measures applied against each, so as not to interfere one with the other.
Microbial pathogen
- Generally, a microorganism which causes disease in its host; more specifically, a term used in preference to microbial “insecticide” to denote a microorganism used by man to suppress insect pest populations.
Parasite
- An animal species which lives on or in a larger animal, the host, feeding upon it, and frequently destroying it. A parasite needs only one or part of one host to reach maturity; cf. parasitoid, predator.
Pheromone
- A pheromone is defined as a chemical or a mixture of chemicals that is released to the exterior by an organism and causes one or more specific reactions in a receiving organism of the same species.
Predator
- An animal which feeds upon other animals (prey) that are usually smaller and weaker than itself, frequently devouring them completely and rapidly. A predator most often is required to seek out and attack more than one prey to reach maturity; cf. parasite, parasitoid.
Resistance
- The relative amount of inherited qualities which allow an organism to influence or reduce the damage done to it by its enemies.
Trap crop
- A small planting of a susceptible and highly attractive host, planted early in the season, or removed in space from the main crop, in order to divert attack and infestation by pets and allow for their easy destruction.
