BSPM 356C - Horticultural Entomology: Landscape Plants

  • 1 credit
View available sections

In BSPM 356C (Horticultural Entomology: Landscape Plants) the focus is on insects and mites associated with shade trees, shrubs, turfgrass and other ornamental landscape plants. 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 will be done through a combination of activities that include online lectures with associated discussion, development of student projects, and shared resources.

This is a four-week asynchronous course. There is no official meeting time and during the week students are able to set their own schedule of class participation. All lectures, quizzes, recommended readings, and weekly project assignments will be released at the beginning of this course. Due dates of assignments will be staggered with all to be completed by the end of this course.

Topics to be presented in five main sections:

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

Additional courses in this series are BSPM 356A (Horticultural Entomology Introduction) and BSPM 356C (Horticultural Entomology: Landscape Plants), which are offered sequentially. BSPM 356A, a suitable prerequisite or instructor override, is required to enroll in either BSPM 356B or BSPM 356C.
