Thrips species associated with cotton in the northern texas rolling plains

Yellow and blue sticky cup traps were used to monitor thrips in wheat and cotton. Plant washing was used to determine the actual thrips species infesting cotton. Ten species of thrips were collected on sticky traps in wheat, and eight species were collected on sticky traps in cotton. However, only six species of thrips were recovered from cotton using the plant washing technique. These six species were Frankliniella exigua (Hood), F. fusca (Hinds), F. genuina Hood, F. occidentalis (Pergande), F. tritici (Fitch) and Thrips tabaci Lindeman. Frankliniella occidentalis was the most abundant species found on traps and in plant washing. Frankliniella exigua and F. genuina were found in plant wash samples, but neither was recovered from the sticky traps. The species capture data indicate that sticky traps in cotton and wheat did not adequately indicate the species composition of thrips that infest cotton. Additionally, thrips captures on sticky traps in wheat were not correlated with captures on sticky traps in cotton, and captures on sticky traps in cotton were not correlated with numbers of thrips recovered from plant washing.
