ENT 317 Turfgrass Insect Management: Introduction to entomology and management of insect pests of cool- and warm- season turfgrass.


Turfgrass entomology requires a thorough understanding of insects and their relatives, an introduction to integrated pest (crop) management, a fundamental understanding of key pests of cool and warm season turfgrass and an introduction to control strategies. Students will be introduced to a wide array of educational and organizational web sites to strengthen their understanding of turfgrass entomology. Students also will be encouraged to develop a web based notebook which they can utilize upon completion of the course. Students will be invited to share their experiences with pest problems and methods of suppressing insects and mites through cultural, biorational, conventional and alternative management strategies.

The course is broken down as follows:

  • Welcome Introduction to Turfgrass Entomology
  • Insects and their Relatives
  • Metamorphosis - The Life Cycle of Insects
  • Characteristics of Adults in the Insect Orders
  • Integrated Pest Management
  • Management Strategies
  • Cool Season Pests
  • Warm Season Pests
  • Lyme Disease
  • Miscellaneous and Nuisance Pests
  • Non Target Organisms

Course Objectives

Upon completion of ENT 317, students will have learned to:

  • Develop diagnostic skills that will enable class members to differentiate an insect from related members of the Phylum Arthropoda (jointed-foot). Example: How can you distinguish a member of the Class Diplopoda from the Class Insecta? (Hint = how many pair of legs, how many major body parts, etc.)
  • Develop skills which will allow you to implement an Integrated Pest Management Program at your place of employment.
  • Become familiar with the Food Quality Protection Act (F.Q.P.A.), especially EPA's June 8, 2000 reassessment decision on chlorpyrifos. The course will also include introductions to pertinent web sites such as AUDUBON SOCIETY, BIRC, EPA, EXTOXNET, FQPA, RISE, USDA-IPM, and others.
  • Become familiar with the identification and life cycles of Key Pests of Cool-Season and Warm-Season Turfgrass. Some of the key pests that you will be introduced to include the scarab white grub complex, annual bluegrass weevil, black cutworm, bluegrass billbug, hairy chinch bug, sod webworm, mole cricket complex, imported fire ants, fall armyworm, and other associated pests.
  • Determine where you can locate current pest control suggestions from your current state or country. Class members will be provided with industry web sites in case you want to review a select label and the respective M.S.D.S. sheet. Also, why is it important to always check your local Pesticide Hypersensitivity Listing prior to applying a registered control measure?
  • Become familiar with alternative pest control suppression strategies such as spinosyn, entomogenous nematodes, and related registered biorational formulations. Also, what is an endophyte?
  • Develop an appreciation for beneficial nontarget organisms and how pesticides may affect their viability.
  • Each class member will be encouraged to develop a web site bookmark-notebook which they can continue to use upon completing ENT317. Key web sites with special topics will be introduced via the Discussion Forum. These could include GCSAA, USGA, EPA, FQPA, etc. on select topics that relate to the course.

Please refer to the University Grading Policy for Undergraduate Courses for additional information about University grading policies.

If, for reasons beyond the student's control, a student is prevented from completing a course within the prescribed time, the grade in that course may be deferred with the concurrence of the instructor. The symbol DF appears on the student's transcript until the course has been completed. Non-emergency permission for filing a deferred grade must be requested by the student before the beginning of the final examination period. In an emergency situation, an instructor can approve a deferred grade after the final exam period has started. Under emergency conditions during which the instructor is unavailable, authorization is required from one of the following: the dean of the college in which the candidate is enrolled; the executive director of the Division of Undergraduate Studies if the student is enrolled in that division or is a provisional student; or the campus chancellor of the student's associated Penn State campus.

For additional information please refer to the Deferring a Grade page.

Academic Integrity

Academic integrity—scholarship free of fraud and deception—is an important educational objective of Penn State. To learn more about academic integrity at Penn State, please visit the Penn State Academic Integrity site. Academic dishonesty can lead to a failing grade or referral to the Office of Student Accountability and Conflict Response.

Academic dishonesty includes but is not limited to

  • cheating,
  • plagiarism,
  • fabrication of information or citations,
  • facilitating acts of academic dishonesty by others,
  • unauthorized prior possession of examinations,
  • submitting the work of another person or work previously used without informing the instructor and securing written approval, and
  • tampering with the academic work of other students.
How Academic Integrity Violations Are Handled

In cases where academic integrity is questioned, the Policy on Academic Integrity indicates that procedure requires an instructor to notify a student of suspected dishonesty before filing a charge and recommended sanction with the college. Procedures allow a student to accept or contest a charge. If a student chooses to contest a charge, the case will then be managed by the respective college or campus Academic Integrity Committee. If a disciplinary sanction also is recommended, the case will be referred to the Office of Student Accountability and Conflict Response. 

All Penn State colleges abide by this Penn State policy, but review procedures may vary by college when academic dishonesty is suspected. Information about Penn State's academic integrity policy and college review procedures is included in the information that students receive upon enrolling in a course. To obtain that information in advance of enrolling in a course, please contact us by going to the Contacts & Help page.

Additionally, World Campus students are expected to act with civility and personal integrity; respect other students' dignity, rights, and property; and help create and maintain an environment in which all can succeed through the fruits of their own efforts. An environment of academic integrity is requisite to respect for oneself and others, as well as a civil community.
