Tuckerella ornata (Tucker), A mite new for Brazil and other tetranychoidea (Acari) from the state of Pará

Abstract

Tuckerella ornata (Tucker) is, for the first time, recorded from Brazil (Belem, State of Pará) and also for the first time on cocoa. The female is carmine in color with white dorsal fan-like setae. It was found on woody stems of cocoa plants, where most of the outer tissues have turned corky, but, where areas of live tissue are still present; it was also found inside cracks of the stems. Other Tetranychoid mites from Pará include: - Tenuipalpus heveae Baker, found on the lower face of median to old rubber tree leaves (Hevea sp.); rather large populations were observed, causing a light leaf distortion and bronzing; it is not considered as a pest. - Oligonychus mangiferus (Rahman & Punjab) causes intense leaf bronzing on Terminalia catappa L., an ornamental tree. Rather large populations of this mite were observed on the upper leaf surface; much dirt is caught in their webbings. - Tetranychus desertorum Banks was observed damaging jute, Corchorus capsularis L., causing intense chlorosis to the leaves. Collected at Alenquer, Pará.
