Insect and Mite: Bug Quiz Bowl 1 By Raymond A. Cloyd

Plant protection of greenhouse-grown horticultural crops requires a basic knowledge of the biology, behavior, and life cycle of the most common insect and mite pests such as aphids, whiteflies, thrips, and spider mites. It also requires a fundamental understanding of the pesticides (insecticides and miticides) and biological control agents (parasitoids and predators) that can be used to either suppress or regulate populations of insect and mite pests.

Therefore, in this article, I am going to determine how proficient you are in regards to your knowledge of insect and mite pests, pesticides, and biological control agents. Below are thirteen multiple choice questions (the answers are located at the bottom of the pageÉby the wayÉno cheating). It should be noted that there may be more than one correct answer. Good Luck!
