Always present, in small or moderate numbers
Endemic
1 of 11
Not normally present but may be outbreaks whre they rapidly become a major problem.
Epidemic
2 of 11
Native to the area
Indigenous
3 of 11
Releases an artificial scent attracting the pests (usually attracted to mates this way) to either show the pest is present or to kill all the pests/enough of one gender so the population can’t be maintained (usually in enclosed areas – greenhouse)
Pheromone traps
4 of 11
Crops that are more productive when grown together
Companion Crops
5 of 11
Cultivation of different crop each year
Crop rotation
6 of 11
Beetle banks and hedgerows can increase populations of natural predators
Predator habitats
7 of 11
predator/pathogen species introduced to control pests. However they must be selected carefully as it can go wrong – Cane toads Australia
Biological control
8 of 11
Exposing the males to gamma radiation sterilises them so no offspring is produced reducing populations. It’s species specific (doesn’t affect non target species), however it has failed in some cases – mosquitoes it altered their behaviour
Sterile male techniques
9 of 11
Maximise total yield by spreading available inputs over large area of land
Extensive agriculture
10 of 11
Large inputs over small areas of land. Productive but not very efficient.
