Scouting a developing crop is an important part of an integrated pest management (IPM) strategy. Sometimes an area not considered is the impact of beneficial insects. Curtis Young discussed important factors to consider when controlling pests at the 2020 Conservation Tillage Conference.
“Not all arthropod organisms (insects) are pests. There are beneficial insects, spiders, predatory mites, bacteria, viruses, fungi, and nematodes,” Young said. “Each of these has a role in managing and suppressing pest populations in the field.”
Beneficial insects play many key roles in crop production. Pollination is an important function; pest control is another.
“There are insects, spiders, mites and others that eat the harmful insects. These are often referred to as biological control agents. They include predators, parasitoids and parasites,” Young said. “They are useful at suppressing pest species populations like aphids, mites, and scale insects.”
