AGBB 1011 - Horticultural Entomology: Food Crops

  • NonCredit

Overview:

AGBB 1011 (Horticultural Entomology: Food Crops) is the second of three noncredit courses that collectively cover the insects that one may commonly find feeding on plants in yards, gardens and landscape settings.

Horticultural Entomology (AGBB 1010-1012) aims to provide a means of continuing education for those already professionally involved in plant protection. This course should also be of interest to most anyone who has an interest in plants and their care, and would like to learn more about the insects found in yards and gardens and to learn about their management.

Learning Objectives:

In AGBB 1011 (Horticultural Entomology: Food Crops) focus is on the primary insect and mite pests associated with vegetables, fruits, and herbs. For all key pest groups students will learn to identify the insects and their associated injury so they can assess damage potential in field situations. Students will understand best management practices for these pests and learn how to locate available resources that can assist in handling specific pest problems.

This is a five week asynchronous course. There is no official meeting time and during the week students are able to set their own schedule of class participation. Each week on Monday at noon MST the lectures, recommended readings, and weekly project assignments will be released. Topics to be covered include:

• Week One: Insects that affect seedling plants (cutworms, root maggots); generalist pests (earwigs, slugs)
• Week Two: Insects that chew on leaves of plants (caterpillars, leaf beetles, grasshoppers)
• Week Three: Insects that directly damage fruit (codling moth, fruit flies), corn earworm and relatives, root/crown borers, stem borers, leafminers.
• Week Four: Insects that feed with sucking mouthparts (aphids, whiteflies, true bugs)
• Week Five: Psyllids, leafhoppers, spider mites, thrips. Insect vectored plant diseases to vegetables, fruits, and flowers.

Additional courses in this series are AGBB 1010 (Horticultural Entomology Introduction) and AGBB 1012 (Horticultural Entomology: Landscape Plants), which are offered sequentially. AGBB 1010, a suitable prerequisite or instructor override, is required to enroll in either AGBB 1011 or AGBB 1012.

Noncredit courses do not produce academic credit nor appear on a Colorado State University academic transcript.
