Abstract

This research was designed to study the effects of sorghum maturity on abundance and damage potential of Banks grass mite,Oligonychus pratensis (Banks). More mites per plant were recorded on the latest maturing line (M100) and the least on the early maturing lines (60M and CK60). Mite densities on B407 (late maturity) did not differ from any of the lines tested. Mite densities were positively correlated with leaf area. In contrast, mite feeding damage was significantly lower on the late maturing lines, demonstrating that sorghum susceptibility to mite feeding increases as plants reach anthesis and caryopsis.
