@article{A. Abou El Atta_A Ali_A M Hammd_2023, title={Efficiency of entomopathogenic nematode and certain bio-agents as biological control against the tow-spotted spider mite, Tetranychus urticae Koch}, volume={3}, url={https://dzarc.com/entomology/article/view/264}, abstractNote={<p>The objective of this study was to assess the efficiency of biocontrol agents such as entomopathogenic nematodes (EPNs) <em>Heterorhabditis bacteriophora </em>and<em> Steinernema carpocapsae </em>to Abamectin against the two-spotted spider mite <em>Tetranychus urticae</em> under laboratory settings. The mortality percentages of <em>H. bacteriophora</em> were 13.33 to 26.66% and 10 to 23.33% when using 2000 and 1000 juveniles, respectively. Moreover, mortality percentages from 6.6 to 26.66% for <em>S. capocapsae</em> were identical for both two levels. In contrast to Abamectin, Bioarc (<em>Bacillus megaterium</em>), Biozeid (<em>Trichodema album</em>), and Baroque agents were tested against <em>T. urticae</em> under greenhouse conditions. Bioarc had the highest mean reduction (96.28%) compared to Abamectin (99.16%), although Biozeid and Baroque were approximately equivalent in terms of mortality reduction (95.48% and 95.2%, respectively).</p>}, number={1}, journal={Journal of Applied Entomologist}, author={A.
