The purpose of this experiment was to determine the effect of insecticide on ladybugs. I became interested in this idea because I know that ladybugs are beneficial insects. They live around insect pests, which leads to accidental spraying of the ladybugs. Farmers need the ladybugs to help keep down pest population, and need to avoid killing them accidentally. The information gained from this experiment can warn farmers to be extra-careful when using insecticide.
