Abstract

Some winter host plants of thrips.

Abstract

Fourteen species of the family Thripidae and four species of Phlaeothripidae were collected from winter host plants in northern Georgia. In all, 122 samples of 26 plant species were taken during the winters of 1968-70. Frankliniella fusca (Hinds) was collected from 16 species of plants, and F. tritici (Fitch) was recorded from nine winter hosts growing in and adjacent to cotton fields. Both species are important pests of seedling cotton. Microcephalothrips abdominalis (D.L. Crawford) was taken from 10 of the plant species examined. Andropogon virginicus, a common plant in the area, was found to harbour nine species of thrips during the winter. Most of the plants examined remain green over winter, and reproduction of some thrips species was indicated by the presence of nymphs and gravid females. The species of thrips are listed along with the plants and dates on which they were collected.
