2016 Autumn Seminar Series
“Biological control in research greenhouses – how to make it work”.
Biological control is a pest management tactic that uses beneficial organisms to manage and control pests. While the tactic is not new, there have been recent advances and developments that have made the tactic more appealing to research and commercial greenhouse production systems. In North America most vegetable greenhouse production facilities rely on biological control in one way or another. And in the past 2-3 years the adoption of biological control by ornamental greenhouses has increased significantly. Some of the most significant developments include increased availability of beneficial organisms, better understanding of their biology, improved efficacy, increased public demand for reduced insecticide use, and decrease in overall costs. Research facilities at universities and research centers are now using or planning to use biological control to manage most of their insect pests. During his presentation Dr. Canas will discuss the key information that needs to be considered when developing a biological control program for greenhouses at a research university, including examples of programs against whiteflies, thrips, spider mites and aphids. He will use research based examples to showcase best management techniques that are useful for the adoption of biological control as a pest management tactic. He will provide examples from other greenhouses at Ohio State that are already using this tactic, some of their costs, and other important aspects to consider for the successful implementation of a biological control program. Dr. Canas will also discuss advantages of biological control and will address concerns. Please feel free to come with a list of questions regarding this pest management technique as there will be a Q and A session at the end of the presentation.
