Ecology of the Lucerne ‘Flea’

Nature volume 131, page 556 (15 April 1933) | Download Citation



THE so-called lucerne ‘flea’, Smynthurus viridis, is an insect of the spring-tail group (order Collembola) which is widely spread in Europe. It also occurs in the southern hemisphere, where it has most probably been introduced and, in South Australia, it has become a major pest of lucerne. It is a common insect in Britain and, taking advantage of this fact, Mr. D. Stewart Maclagan has made an extensive study of the role of environmental factors in relation to the normal natural increase of the SmynthurusSmynthurus viridis population.
