Ent 4015: Ornamentals and Turf Entomology

Problem Solving Assignment: Developing an IPM program for a greenhouse pest.

Each of you will develop an IPM program for a target greenhouse pest. You are to develop an IPM program at low density pest numbers, which includes biorational pesticides and biocontrol agents, and at high density pest numbers, which include conventional, broad spectrum pesticides. The assignment will count toward 5% of your final grade.

You may work in groups for the class presentation, but please turn in individual papers. Students may not copy each other's answers, although they are encouraged to discuss the assignment with their classmates. Please do not copy and paste text from the websites; instead, paraphrase or summarize your answers. Answers that appear too similar, or appear to be copied, will be given a grade of 0 that cannot be dropped. Please be sure to include a list of references in your paper.

The IPM program must include:

1. Family and order of the pest.

2. Economic importance: Host species and importance.

3. Description of pest and life cycle (draw on board): Duration of life stages, number of days, number of eggs, etc. Mention how to discriminate pest from closely related others if you are given 2 pests.

4. Monitoring for the pest: Damage symptoms, sticky cards (color?), traps, indicator plants.

5. Low density management: BC agents (for what life stages); Biorational pesticides that can be used with BC agents, such as IGR, microbial, soap, oil, and botanical insecticides.

6. High density management: Conventional pesticides.

Pests to chose from:

1. Greenhouse and western flower thrips.

2. Spider mites and cyclamen mite.

3. Greenhouse and silverleaf whiteflies.

4. Citrus and longtailed mealybugs.

5. Fungus gnats and shore flies.

6. Soft scales (brown, hemispherical).
