Paradox of the pesticides

[3] Recent studies suggest that such a paradox might not be necessarily caused by the reduction of the predator population by harvesting itself, for example, by a pesticide.

The host population is reduced at the moment of harvesting, and simultaneously, the intraspecific density effect is weakened.

Thus, changes in life history strategy (patterns of growth, reproduction and survivorship) can also contribute to the paradox.

[6] There is not only one way to practice IPM, but some methods include using mechanical trapping devices or increasing the abundance of natural predators.

[7] IPM is also often touted for its environmental and health benefits, since insecticides are sprayed only when a threshold of damage is reached..
