7.2 Least-Toxic Controls<br />

In this approach Least-toxic chemicals to humans, non-target species and the<br />

environment are used. A range of least toxic pesticides for different pests have<br />

been developed and could be found on websites and IPM text books.<br />

7.3 Biological Controls<br />

Biological controls include the appropriate conservation of pests’ natural<br />

predators, parasites and diseases, and the judicious augmentation of these<br />

species via predator releases, applications of parasites, and inoculations of<br />

diseases.<br />

7.4 Physical Controls<br />

Also pests may be controlled by using physical means which may include:<br />

• Desiccants (diatomaceous earth, silica aerogel)<br />

• Barriers (sticky, band, water)<br />

• Traps (mechanical, glueboard, sticky)<br />

• Environmental manipulation (of temperature, humidity or light)<br />

• Electric currents (electrogun, electric fences and traps)<br />

• Manual removal (nets, lice combs).<br />

7.5 Organic farming<br />
