Excerpt from Relative Toxicity of Chloropicrin, Phosphine, Edc-Ccl4, and Ccl4-Cs2 to Various Life Stages of the Indian Meal Moth Fumigations were conducted in liter glass bottles sealed with plastic caps. A small rubber scrum stopper was inserted through each cap to permit use of a microsyringe for sampling of the gas concentrations within the bottle. A column of four interconnected perforated polystyrene specimen bottles small enough to pass through the narrow neck of the glass bottle served as test cages. The cages and a remote humidity sensor were suspended beneath the glass bottle cap. Life stages of the Indian meal moth placed in the four cages included fewer than 100 eggs, 0 to 24 hours old, 10 larvae 2 weeks old, 10 larvae 5 weeks old, and 10 pupae. A small amount of suitable food material was placed in each cage. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.
