While for emamectin benzoate, it was 92 and 84%, respectively. According to the standards of the International Organization for Biological Control (IOBC),azdrachtin came in first class (1- harmless) in terms of the effect of residues on adult insects, while emamectin benzoate came in the third class (3 = moderately harmful) in terms of the effect of residues on insects adults and larvae.<\/span><\/p>\n<p><span style=\"font-family: 'times new roman', times, serif;\"><strong>Keywords<\/strong>: azdirachtin, emamectin benzoate, <em>Cryptolaemus montrouzieri<\/em>, side effect.<\/span><\/p>\n<p><strong><span style=\"font-family: 'times new roman', times, serif;\">Full Paper in Arabic: <a href=\"http:\/\/agri-research-journal.net\/SjarEn\/wp-content\/uploads\/v12n3p41.pdf\">pdf<\/a><\/span><\/strong><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Shadi faskha*(1) , Bahaa Al rahban(2), \u00a0Ghiwa nehmeh(1) , and Basel Darwish(1) (1).
