Excerpt from The Genetics of the Grouse Locust: Tettigidea Parvipennis Harris Although the experimental breeding was carried on in the regular breeding cages as described.by'hsbours (1914, 19193.l925. 1999, other Jars and containers have been tried withvarying degrees of success. The principal disadvantages of the regular glass jars are their large site and cost, yet it has been found that they are the best for maxim batches of off spring. Screen cages with tin around the bottom to about four inches in height were tried. Although no change in sise of cage was made, the numbers of offspring were smaller. Indications are that such cages can be used effectively if a more constant tem parature than the ordinary menhouse daily fluctuations is min-o tained. Perhaps one of the principal advantages of the glass jars is that the temperature changes less abruptly, though they do attain an undesirably high temperature when in the sunshine. Screen cages also permitted greater changes of humidity and soil desiccation. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books. Find more at ...
