Master Gardener Basic Entomology Lesson Plan


Approach: This lesson plan is designed to introduce Master Gardeners to the fundamentals of insect and mite management.A slide show has been provided to cover the basic information.This should take no longer than 2 hours of the 3 hour meeting.Assuming a half hour break this should leave about 30 minutes for interactive exercises to stimulate learning and discussion.Items 1-7 which include a Japanese beetle example, are fundamental. Item 8 includes information other common pests that can be included be used at the discretion of the Educator for either basic training or advanced training on topical issues.You may want to use the link provided to print out a 6 slide per page handouts of all the slides.



  1. What is a pest
  2. Arthropod fundamentals

                                                               i.      What are arthropods, and Insect

                                                             ii.      Use Japanese beetle to introduce concepts of nomenclature.

                                                            iii.      They make up most of the described species of terrestrial organism

                                                           iv.      Few arthropods are pests, most are benign, some are beneficial.

Review shared characteristics of arthropods

                                                             v.      Arthropods grow by molting, not by stretching skin

  1. Basic biology and anatomy of insects and mites

                                                               i.      How insects can grow � Complete and incomplete metamorphosis

1.      Relationship between metamorphosis and food of adult and immature stage flies and beetles vs grasshoppers and true bugs.

ii.Insect Body Characteristics

����� ������ 1. Overview of body regions

����� ������ 2.Head structure and function

i.adaptations to help them feed � chewing vs sucking

ii.adaptations to help them see and smell

3.Thorax structure and function

����� i.adaptations for flight, and digging

4.Abdomen structure and function

iii.Internal Insect Systems

�� 1.Review location of

����������� Circulatory, digestive, nervous, and respiratory systems.

  1. Diagnosis of insect and mite damage using representative pests
    1. Leaf Chewers. (Beetles, Sawflies, Caterpillars, Grasshoppers)
    2. Leaf Suckers(Aphids, hoppers, scales, plant bugs, thrips, spider mites)
    3. Boring (beetles, caterpillars)

1.Make copies of a list of home landscape insecticides (E-221W) Buy some common insecticides and bring to workshop.


2. Bring an insect collection if you have one., or Get natural enemy and pest cards from U of IL.

- Break gardeners into groups have them look at cards and determine

����������� - Insect or mite?

���� ������ - Complete or incomplete metamorphosis

����������� - Beneficial or Pest
