Abstract

The beet leafhopper (Eutettix tenella Baker), is the most serious pest of the western sugar beet. It has through the disease it tranmits caused periodic losses to the western sugarbeet industry, amounting in the aggregate to many millions of dollars. Curly-leaf, the disease which this insect transmits, has in some of its worst outbreaks caused the abandonment of thousands of acres of beets in certain districts and a serious reduction in tonnage of the remainder, so that the total loss in a single area has several times passed the million-dollar mark. Besides these striking and widespread outbreaks which fortunately have not been numerous, it has continued from year to year to reduce tonnage in certain districts until at least seven factories have temporarily or permanently suspended operation on account of losses from this source.
