Research Interests

Entomology; Turfgrass Science, Biology and Ecology of Turfgrass Insects; Insect Behavior; Spatial Distribution of Populations; Biological Control; Entomopathogenic Nematodes

My research program focuses on understanding the biology and ecology of turfgrass insect populations to improve current management practices and develop novel, more sustainable management and monitoring programs. Given the heavy reliance on chemical controls in many managed turfgrass systems, little is known about the ecology of many soil arthropod pests and communities. I have used the annual bluegrass weevil (Listronotus maculicollis Kirby), a severe and widespread pest of intensely managed turfgrass, as a model to explore many questions that I have regarding insect ecology.

Course Overview

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 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:

  • Insects and their relatives
  • Insect structure and function
  • Insect Orders
  • Integrated Pest Management (Chemical, Biological, Cultural, Genetic Control)
  • Turfgrass Insect Pest Groups (Leaf, Stem/Crown, Root feeders)
  • Social Insects and Nuisance Pests
  • Unintended Consequences of Chemical Management

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 that will allow you to implement an Integrated Pest Management Program at your place of employment.
  • 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.
  • Develop an appreciation for beneficial nontarget organisms and how pesticides may affect their viability.

Course Materials

The following materials are not required, but recommended (as they will help in your career in turfgrass management):

  • Vittum, P. J., M. Villani, and H. Tashiro (1999) Turfgrass Insects of United States and Canada. Cornell University Press.
  • Potter, D.A. (1998) Destructive Turfgrass Insects: Biology, Diagnosis and Control. John Wiley and Son, Hoboken, NY.

Horticulture and Landscape Students:

  • Cranshaw, W. (2004) Garden insects of North America: the ultimate guide to backyard bugs. Princeton Univ Press.

Assignments/Exams

For each week of study (and to receive Penn State credit) each student will:

  • Go through each module and read (assigned only) related readings
  • Complete all homework assignments
  • Complete all quizzes
  • Complete all exams
  • Complete the final exam

Homework Assignments: There will be 3 assignments throughout the course. Two assignments are "labs" and are designed to follow along with the control tactic modules. The last assignment ("IPM Letter") will require the student to synthetize all that they have learned in the class to develop a plan of attack for controlling a hypothetical pest outbreak. This will be in the form of a professional letter to a board or supervisor. Assignments are worth 20 points each.

Quizzes: There will be 14 quizzes throughout the course. Quizzes are not a group activity. Each quiz is worth 10 points. The lowest quiz grade at the end of the semester will be dropped.

Exams: Exams 1 and 2, which covers Modules 1-5 and Modules 6-12, respectively, are each worth 75 points. The final exam, which covers all modules (cumulative), is worth 100 points. Each exam is a 2 hour, online, closed book exam.

Academic Integrity

Academic integrity is the pursuit of scholarly activity in an open, honest and responsible manner. Academic integrity is a basic guiding principle for all academic activity at The Pennsylvania State University, and all members of the University community are expected to act in accordance with this principle. Consistent with this expectation, students should act with 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 efforts. Academic integrity includes a commitment not to engage in or tolerate acts of falsification, misrepresentation or deception. Such acts of dishonesty violate the fundamental ethical principles of the University community and compromise the worth of work completed by others (see Faculty Senate Policy 49-20, G-9 Procedures and the Code of Conduct).

Read the Academic Integrity Guidelines for the College of Agricultural Sciences

A lack of knowledge or understanding of the University's Academic Integrity policy and the types of actions it prohibits and/or requires does not excuse one from complying with the policy. Penn State and the College of Agricultural Sciences take violations of academic integrity very seriously. Faculty, alumni, staff and fellow students expect each student to uphold the University's standards of academic integrity both inside and outside of the classroom.
