Biological Control Techniques

Hormone control

behavioral chemicals

Example= bag-a-bug, which emits sexually attractive scent to lure the malle in, and then captures the male

used to control Japanese beetle pest

Example= put out stations that frequently emit lots of female scent so that the males cannot pinpoint females to mate with

pheromones (sex hormones)

Reproductive control

release of incompatible pest strains

use of chemical sterilants

release of sterile male insects

these have equal mating success as normal males

Control by other organisms

Example= large rabbit population in Australia

myxomatosis virus introduced and the rabbit population is diminished

Example= prickly pear cactus brought into Australia from SW US

cactoblastis caterpillars brought in to eat out their center and they are eliminated

spread easily because of asexual reproduction and spines to be carried by

predators, pathogens, parasites
