During a 4-year study in Fayette County, the first collections of adult potato leafhoppers from mature alfalfa occurred on May 4, 1981, May 7, 1982, May 31, 1984, and May 10, 1985. Populations peaked in early July and averaged 4.9 and 2.2 adults per sweep in spring-seeded (first year) and mature stands, respectively. The sex ratio (F:M) of the early migrants in May and early June ran as high as 4.8:1. Populations in all study fields collapsed after harvest in July and never exceeded 1.1 adults per sweep throughout the remainder of the season.
