Cultural Pest Control
Sterile Male Techniques
Many female insects only mate once. If they mate with a sterile male they will not produce offspring
-
If enough are released, the number of fertile matings will decrease and the mortality rate will be higher than the birth rate, meaning the population decreases
-
Didn't work on mosquitoes- the sterile males behaved differently, meaning the females wouldn't mate with them and would instead mate with fertile males
Biological Control

-
Unsuccessful
The Florida Rosy Wolfsnail was introduced to the islands of Polynesia to control GALS, but it also ate indigenous Partulid snails. Now 48 species of Partulid snails are extinct.

Companion Crops
-
Barrier crops
smell of onions masks the smell of carrots, so rootflies can't find them
-
Predator Habitats
-
e.g. beetle banks, ladybug houses etc
Crop rotation
Growing the same crop every year means that predators can settle so have already colonised the next year you grow that crop.
Growing different crops = predators of one crop have died off or emigrated before that crop is planted again
