ABSTRACT

The field experiments were conducted in 2003, 2004, and 2005 to evaluate a direct effect of the dock leaf beetle (Gastroidea viridula Deg., Coleoptera: Chrysomelidae) releasing on mossy sorrel (Rumex confertus Willd.). Significantly greater amount of larvae was recorded on plants on which adults were previously released. Also greater leaf damage index and lesser height of mossy sorrel plants were observed on those plants in comparison to control.

Key words: weeds, herbicides, mossy sorrel, Rumex confertus Willd., biological control, the dock leaf beetle, Gastroidea viridula Deg..
