Sinopsis

Excerpt from Mosquito ControlIntroductory - The campaign against mosquitoes recorded in this Bulletin was undertaken by the California Experiment Station at the urgent request Of the Burlingame Improvement Club. Late in May, 1904, a letter was received by the entomologist of the Station, asking for aid in relief from mosquitoes in the vicinity of Burlingame, where they had become exceedingly abundant and annoying. This request was made too late to do any effective control for that season, but it was recommended that a preliminary survey be made with a View to obtain ing data for future work. The writer was consequently detailed to make this survey, and three weeks were spent in the neighborhood making collections and locating breeding grounds. In this study it was soon determined that the mosquito giving practically all of the trouble (estimated at 95 per cent) was a species that bred in salt or brackish water only, and that in any work looking toward control, the salt-marsh area must receive first consideration. This being known, the pre liminary report made to the Burlingame Improvement Club gave but little encouragement, because of the extent of the marsh land that must be included in the problem. It was further stated, however, that if they were considering the problem in earnest, and wished to go to the expense necessary to control this large breeding ground, the Ex periment Station would be glad to outline a plan of campaign for the following season.About the PublisherForgotten Books publishes hundreds of thousands of rare and classic books.
