ABSTRACT



A field experiment was conducted to determine a direct effect of five herbicides selected on Rumex confertus Willd., and an indirect effect on phytophagous insects. Mossy sorrel is the host of Hypera rumicis L. (Coleoptera, Curculionidae), Apion miniatum Germ. (Coleoptera, Curculionidae), and Pegomya nigritarsis Ztt. (Diptera, Anthomyiidae). The herbicide treatment affected the plant growth, yet new leaf rosettes were produced again by the end of the summer. However, the herbicide treatment reduced the leaf area and the number of seeds damaged by larvae. The insect development, seasonal adult abundance, and feeding by larvae decreased significantly on the herbicide treated plants.

Key words: herbicides, sub-lethal effects, growth, Rumex confertus Willd., biological agent, Hypera rumicis L., Apion miniatum Germ., Pegomya nigritarsis Ztt.
