STOCKSCH 326 – Insect Biology

Instructor: George LoCascio       Email: glocascio@umass.edu

Virtual Office hours: Mondays 12:00pm-2:00pm; Wednesdays 6:00pm-7:00pm

Course description: Ever wonder what is eating your garden plants? What are the yellow and black striped insects hovering around your Aster flowers? In Insects of Food Crops, our course focuses on agriculturally important insects, the detrimental and the beneficial. We will identify taxonomic insect orders, identify common features within those groups, and use keys to identify major agriculture important insects to family and some to species. In addition, we will explore conventional and biological methods of pest insect control. We will also discuss insect conservation and diversity. As an optional exercise, students can develop an insect photo collection.

Course objectives:

  • Learn major taxonomic insect orders important for agricultural crops
  • Identify important agriculture insects to species level with the aid of keys
  • Understand common pest insect control methods (Conventional and Biological)
  • Describe general insect biology and life histories

Instructional method:

Through power point lectures, online quizzes and discussions, reading literature, watching videos, and with various online identifying resources, we will dive into the insect world. We will use the online platform Blackboard. All of these materials will be fair game on quizzes.
