Pest Biology Outline
Generally speaking, arthropod, plant, and pathogen pest species pose strong dispersal abilities and populations can increase rapidly.
Also arthropods and pathogens often have strong host finding abilities.

Q
Resistance
A
Overuse of pesticides can lead to entire populations of pest species to gain resistance over short time spans.
3
Q
Resurgence
A
When a pests natural enemies are wiped out due to pesticide applications.
Initially pest population declines, however rebounds, usually to high numbers, due to the absence of natural predators.
4
Q
Secondary
A
Occurs alongside resurgence, where a previously innocuous pest population erupts following a pesticide application, once again due to the lack of predatory presence.
