You will learn the usage of insect traps.
After completing this tutorial, you will be able to complete the following:
Scientists who study insects are called entomologists. Entomologists often use insect traps to catch specimens for their research. Insect traps are used to learn more about individual insects and to estimate their population sizes. The type of trap that is used depends upon the species of insect that the entomologist wants to catch. Traps use food, visual lures, chemical attractants, and pheromones as bait. The traps are designed to avoid harming other animals or people, and to avoid leaving behind organic residue. Visual lures use bright colors and shapes to attract insects, while chemical attractants or pheromones may attract only a specific gender. Pheromones are chemicals that are excreted by certain animals, and they affect animals of the same species. The type of bait used also depends upon the species of insect a scientist is trying to catch. After catching the insects, entomologists may use hand lenses and/or microscope slides to observe them in a detailed way. In addition, scientists may use metric rulers to measure their size, or the size of their parts, which can often help in identification.
