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
