Abstract:In studies conducted in a lath house at Mesa, Arizona, in 1960 the population density of leafhoppers, Aceratagallia curvata Oman, per plant ranged from 2 to 14 males, females, and sexes combined. Seedling mortality was greatest during the first 5 days of the testing. Mortality owing to direct insect feeding decreased ,arithmetically from males to females to sexes combined. Seedling longevity was in verse geometrical proportion to the number of male and female leafhoppers feeding separately on plants and in inverse arithmetical proportion when the sexes were combined. Longevity of seedlings ranged from 17.5 to 1.5 days as a result of feeding from 2 to 14 leafhoppers per plant, respectively.
