Course Description: This course provides fundamental knowledge required to prevent and manage pest infestations using practical non-chemical and chemical methods. Participants will learn about pests associated with grain, methods and devices used in sampling, the overall value of sampling grain, preventive and responsive management techniques and proper use of grain protectant and fumigation.

Course Goals: This course aims to teach basic skills to those involved in handling, storing and processing grains and oilseeds. These skills will enable participants to make timely pest management decisions, while also protecting the quality of stored grain and the environment. By the end of this course, participants will be able to create and evaluate their own pest management plan.

Target Audience: Grain facility superintendents and managers;  grain industry professionals who have responsibilities relating to grain quality management, pest management, fumigation and protectants; students and others with a professional interest in managing pests in stored grain.

The Course of Study

WEEK 1Details

Lesson 1: Overview
An introduction to Integrated Pest Management (IPM) and how this course will help provide the resources needed to create and implement an IPM plan.

Lesson 2: Identification
Identification is the first step in creating an IPM plan. Ifco you don’t know what you are dealing with it, how can it be managed? This section will cover the basics of identification and how to tell the species apart, looking at the following:

  • Insects
    • Primary feeders
      • Internal
      • External
    • Secondary feeders
      • External
      • Mold feeders (hairy fungus beetle, rusty grain beetle, etc.)

Each section will cover the most seen insect pests in the grain industry, signs of damage and process for identification as well basic biology (lifespan of adults, reproduction, differentiating characteristics, feeding preferences, temperature requirements, etc.).

  •  Vertebrates
    • Basic Identification
      • Birds
      • Mammal

Each section will cover the common pest species in the grain industry, indications or conducive conditions related to the pest and process for identification as well basic biology.

Developer: Peter Mueller, insects; Jerry Heath vertebrates

WEEK 2Details

Lesson 3: Preventive Control
Inspections are a key component in early identification of potential issues. This section will cover self-assessment and suggest the appropriate tools for a self-assessment program. Tools include: flashlight, plan on where to look, what senses to use (smell), and identification of secondary and conducive conditions caused the pests.
Developer: Chelle Hartzer

Lesson 4: Monitoring and Trapping
Monitoring is used to determine pest activity and overall progress of an IPM plan. It can also be a way to identify issues early and mitigate infestation/damage.
This section will cover the who, what, when, where, why and how of trapping and monitoring. Also, once the information has been collected, how to analyze and utilize it.
Developer: James Miller

WEEK 3Details

Lesson 5: Sanitation
Sanitation is not only essential to a pest management program, it can increase effectiveness of a program. This section will cover basic sanitation principles using real-world examples inside and outside of a facility, as well as best practices, including sanitation tools used by the industry.
Developer: Al St. Cyr

Lesson 6: Design and Exclusion Principles
When looking at design and exclusion principles this can include equipment, maintenance issues, equipment that has been decommissioned, as well as how to manage the design of a facility to control pests.
Developer: Matt Frye

WEEK 4Details

Lesson 7: Chemical Management
Once identified, there are several ways to mitigate pests in a facility. This section will cover the chemical options. You’ll learn about the different categories of pesticides, formulations and applications. General overview of fumigation including three main fumigants of methyl bromide, sulfuryl fluoride, phosphine plus safety measures. Chemical management of pests within grain structures and transportation containers will be described.
Developers: Hank Wentworth, fumigation; Forrest E. St. Aubin and Dr. Bhadriraju Subramanyam (Dr. Subi), grain protectants

Lesson 8: Other Management Options
This section will address some of the non-chemical and low-impact responses to pest issues including modified atmospheres, packaging and biologically-based options.

  • Physical controls:
    • aeration
    • extreme temperatures
    • effective packaging
  • Biologically-based controls:
    • controlled atmospheres
    • pheromones
    • repellents
    • insect growth regulators
