Book excerpt: Excerpt from Land-Improvement Measures in Relation to a Possible Control of the Beet Leaf-Hopper and Curly Top F rom the standpoint of control it is important that the beet leafhopper must have a continuous sequence of food plants through out the year ih order to maintain itself from season to season. In the ordinary development of leafhopper populations such a contin nous sequence depends upon three different sets of plants, Since in general there are no perennials capable Of serving as both breeding and food plants throughout the year. The first set of plants carries the insect through the fall-winter-spring period and the next set through the summer period However, the growing period Of these two sets Of plants always overlaps in the Spring, permitting the insect to go from the first to the second, but where fall rains are scanty there is a gap in the fall when summer annuals are dead and winter annuals have not germinated. During this period a third set of plants, functioning as hold-over hosts, is necessary to carry the insect until winter annuals germinate.
