In New York State, leaves of mature apple trees often become stippled and devitalized as a result of feeding by the leafhopper T. pomaria. The species is twobrooded and overwinters in the egg stage on apple. In 1931 the first brood hatched in May; the second brood hatched during the latter half of August. The nymphs are readily killed by nicotine sprays, and since the duration in hatching of either brood was not long in 1931 it appears probable that a single correctly timed treatment may effect a high percentage kill of a brood.
