Eduoard Horace Siegler Collection of Entomology Lantern Slides

The Eduoard Horace Siegler Collection of Entomology Lantern Slides consists of slides that may have been used by travelling extension agents for instructional sessions. The title of one set of slides is "How Insects Attack Garden Vegetables and Methods of Control." It was a joint contribution of the U.S. Department of Agriculture (USDA) Bureau of Entomology and the Extension Service, cooperating with the State Agricultural Colleges in extension work in agriculture and home economics. Some insects described include the Colorado potato beetle, cabbage worm, asparagus beetle, striped cucumber beetle, Mexican bean beetle, potato flea beetle, and squash-vine borer. There are also images of equipment used to spray insects. Another set of slides is titled "Effect of Bentonite and of Hydrated Lime on the Toxicity of Phenothiazine to Codling Moth Larvae." Slides are undated but subjects correspond to Siegler's work from 1915 to 1931.
