Charles Lester Marlatt

Charles Lester Marlatt (born September 26, 1863 in Atchison , Kansas , United States , † March 3, 1954 ) was an American entomologist .

Life

He was born near Atchison , Kansas , in 1863 . His scientific career began at the Kansas State Agricultural College at Kansas State University (BS, 1884; MS, 1886). There he also worked for two years as an "Assistant Professor". Marlatt introduced ladybugs to the United States for biological control and control of the San Jose scale insect . He later worked for the Bureau of Entomology in the United States Department of Agriculture . In 1912 he was appointed chairman of the Federal Horticultural Board . He was president of the Entomological Society of Washington (1897–98) and the American Association of Economic Entomologists (1899).

In 1907 he provided a detailed description of the " periodic cicadas ", which is still valid today. In his article Marlatt suggested dividing the cicadas into 30 separate "broods" (German broods, ~ stems / years). He assigned a Roman number to each Brood . The Broods I-XVII each designated a vintage of the 17 calendar years in the cycle of the "17-year cicadas". The Broods XVIII-XXX each designated a vintage of the 13 calendar years in the cycle of the "13-year cicadas". Research has shown that, in reality, there is not a vintage of cicadas every year. Only 15 different "Broods" were able to be identified. Even so, Marlatt's count remains in use.
