What is the difference between biological control and pesticides?
Pesticides.Pests that affect human health and crops are a major problem.However, one possible consequence of using pesticides is that beneficialorganisms living in the same environment as the pests could also beharmed. This can happen because many pesticides kill more than justthe pest. For example, the lygus bug are pest that feedson alfalfa and canola plants and causes severe damage to these crops.However, pesticides that are sprayed to kill lygus bugs also kill bees.Another downside to using pesticides is that they can also harm thebeneficial insects that normally prey on the pests. This can result inthe populations of pests actually increasing because there are fewerorganisms to prey on them!Biological control.Another way to control insect pests is to use their natural enemies.This method, called biological control, can be very effective and limitsor eliminates the need for pesticides. For example, leafy spurge is aweed that was accidentally introduced into Canada in the late 1800s . Leafy spurge grows faster than naturally occurringpasture grasses. Cattle will not eat leafy spurge, so land that is infestedwith this weed cannot carry livestock. The black dot spurge beetle is asmall beetle that feeds on leafy spurge. The beetle was introduced into Alberta in 1983, and has been very successful incontrolling the spread of leafy spurge. Desirable plants, such as pastureand rangeland grasses, are returning to the areas where leafy spurgeused to grow. Although biological control can work very well, there can be risks.Whenever a new organism that is not native to the area is introducedto an ecosystem, there is always a risk that it will cause harm.
