ABSTRACT

Field and laboratory research was conducted to determine the effect of five herbicides on Rumex confertus Willd. which is the host of Gastroidea viridula Deg. and Gastroidea polygoni L. (Coleoptera: Chrysomelidae). Herbicide treatment effected plant growth, but new leaf rosettes were produced by the end of the summer. Survival, seasonal abundance and development of investigated insects were significantly reduced. Beetles and larvae avoided feeding on herbicide treated plants.

Key words: herbicides, sub-lethal effects, growth, Rumex confertus Willd., biological agent, Gastroidea viridula Deg., Gastroidea polygoni L..
