pest
undesirable organism that causes damage
pathogens
disease causing organisms ( viruses, bacteria, or fungi )
four main groups of pests
weeds, invertebrates, vertebrates, pathogens
biological control
use of natural enemies to control pests and their damage
chemical control
using naturally and or synthetic chemicals to manage pests
mode of action ( pesticide )
how the pest is killed
site of action ( pesticide )
the specific biological system affected within the pest
selective pesticide
toxic to some pests with little to no effect on others
example: some herbicides may kill broadleaf weeds but not grasses
systemic pesticide
absorbed and translocated within a plant or animal
contact pesticide
not absorbed through plant; must directly touch site to be effective
residual pesticides
control pests for longer periods of time
genetic control
manipulating genes of organism or choosing specific genetic traits to pass to offspring
mechanical control
traps, sticky surfaces, etc.
physical control
fences, sealing cracks, screens, etc.
regulatory control
control by governmental agencies
IPM ( Integrated Pest Management )
a balanced and tactical pest control strategy that uses a wide range of pest control tactics
key pests
cause major damages on regular basis
secondary pests
become a problem when a key pest is controlled or absent
occasional pests
become troublesome once in awhile because of factors such as life cycle, environmental change, or human activities
economic threshold
pest population density at which control measures are needed to prevent the pest from reaching economic injury level
economic injury level
pest population density that causes losses equal to the cost of control measures
