| Abstract | Possibilities of the use of entomopathogenic nematodes to control the sugarcane froghopper, Aeneolamia varia. Two experiments where conducted to determine the effectiveness of the nematode Heterorhabditis bacteriophora in controlling nymphs of the sugar froghopper, Aeneolamia varia (F.), as well as the optimum dose of nematodes. The entomogenous nematodes of the genus Heterorhabditis and Steinernema constitute a viable option for the biological control of this pest, because they possess long infective stages that allow their distribution and permanence in the soil. Seventy-two hours after the application, nymph mortality was at 71.35 to 75.4%, with doses of 50 to 100 million infective nematodes per ha. In the experiment with low doses (2 a 4 millions of nematodes per ha) no significant effects were observed. A native nematode was found in the control treatment, and identified as H. indica. Entomogenous nematodes constitute a useful tool to be incorporated to the integrated pest management of A. varia. |
