Tegolophus ipomoeifoliae Keifer (Acari: Eriophyidae) on sweet potato in Presidente Prudente, São Paulo State, Brazil

Abstract

The present study aimed to evaluate the occurrence of eriophyid mites on two sweet potato cultivars [Ipomoea batatas (L.) Lam.] used by growers in the Presidente Prudente region, São Paulo State, Brazil: Uruguaiana and Canadense. The experiment was carried out from April to October 2008 in the agronomic experimental area, located in the municipality of Presidente Prudente (UTM 7,545,369 m N, 459,817 m E, and altitude of 437 m). We collected 30 randomly selected leaves per cultivar fortnightly, from the third pair of leaves of the distal end of the branch. The collected mites were mounted on a modified Berlese medium. A total of 2,649 specimens of Tegolophus ipomoeifoliae Keifer (Eriophyidae) were recovered, with 1,862 in the cultivar Canadense and 787 in the cultivar Uruguaiana.
