We all want the good guys to win, right? Well, it is even more important in agriculture where there are good guys with wonderful names like assassin bugs and pirate bugs, which regularly seek out, kill and eat the bad guys that are eating our crops. This is how nature keeps the balance between good and bad, and our potato and vegetable growers have learned nature’s tricks; they are masters at manipulating the system in their favor. This concept is called biological control, and it uses a broad range of beneficial species that occur naturally in diverse ecosystems to attack pest species that feed on crops, keeping them at levels which do not harm the crops.
This process of one organism regulating populations of another is found throughout nature from microscopic bacteria to alpha predators, like wolves. If we look with inquisitive eyes, we can see this in action in our very own back yards. In production agriculture, biological control can be seen at a much larger scale. It has become a vital component of the farmer’s toolbox that can be used in tandem with other approaches to keep pest populations below damaging levels. The whole system is called Integrated Pest Management; the goal is to use pesticides only as a last resort when pests increase to damaging levels. (more…)
