Although adults of some species have distinctive wing markings, many species are most readily distinguished in the last nymphal immature stage, which is wingless and lacks visible legs. This lowers the rate at which a pest develops resistance to a control, because if almost all pests are killed then those that have resistance will provide the genetic basis of the future population.

Under this scheme, insect control was "supervised" by qualified entomologists and insecticide applications were based on conclusions reached from periodic monitoring of pest and natural-enemy populations.

Examples of these are the powderpost beetleswhich attack the sapwood of hardwoods, and the furniture beetleswhich attacks softwoods, including plywood. The commercial for-profit insectary was excluded from meeting the challenge of developing biological controls for exotic pests, while farmers repeatedly endorsed hundreds of millions of largely wasted tax dollars on so-called eradication projects.

Adults are up to 0. Reliance on knowledge, experience, observation and integration of multiple techniques makes IPM appropriate for organic farming excluding synthetic pesticides.

Habitat modification practices were also shown to enhance biological control.Protecting the country. Reducing risks. Biosecurity New Zealand's focus is on stopping pests and diseases at the border, before they get to New Zealand, and.
