Abstract

We studied the efficacy of infective juveniles (IJ) of Steinernema sp. strain JCL024 and Heterorhabditis sp. strain SL0708 on adults and nymphs of Collaria scenica under greenhouse conditions. Five doses were evaluated (2, 16, 78, 160 IJ) cm-2 leaf) for each nematode. The experiment was evaluated for 21 days every 24 hours, making mortality counts and assessment of damage on Kikuyo grass. The bugs showed 100% mortality after 15 days. Each bug produced an average of 13,000 IJ/6 days. As for the damage did not reach level 2 within 21 days prior to treatment without nematodes that damage introduced 3 with necrosis and apical leaf curl. Thus, Steinernema sp. strain JCL024 and Heterorhabditis sp. strain SL0708 exercised control bug on the grass and kept under the level of damage to the foliage.
