Two treatments (A &amp; B) were conducted and control was untreated. Treatment A with a single pre-blooming application and treatment B with two pre-blooming applications. In 2012, the efficacy of one application was 98.2% in treatment A and 97.4% in treatment B. However after the second application in the treatment B the efficacy reduced to 94.2% while in case single application (treatment A) the efficacy reduced to 85.65%. In 2013 the efficacy of kaolin-particle film in pre-blooming first application were 84.05%, 81.55% in treatments A and B respectively, and after\u00a0 second application to B treatment, the recorded efficacy were 83.12%, 95.82% in treatments A and B respectively. The experiment was also conducted on the foliage of pear trees in the previous two years and the efficacy of Surround WP\u00ae was 90.82%, 89.15% in treatment B in 2012, 2013 respectively while in A were 69.74%,73.84% respectively. In a laboratory experiment with treated and untreated pear leaves adult females spent significantly less time on treated compared to untreated.<\/p>\n<p><strong>Key words:<\/strong> Repellent effect, Particle film technology, Kaolin, Over-wintering females, Pear psylla, <em>Cacopsylla bidens <\/em>(\u0160ulc).<\/p>\n<p dir=\"ltr\">Full paper in Arabic:<\/p>\n<p dir=\"ltr\" style=\"text-align: right;\"><a href=\"http:\/\/agri-research-journal.net\/sjar\/wp-content\/uploads\/p4.pdf\" target=\"_blank\">\u0627\u0644\u062a\u0623\u062b\u064a\u0631 \u0627\u0644\u0637\u0627\u0631\u062f \u0644\u0645\u0631\u0643\u0628 \u0627\u0644\u0643\u0644\u0633 \u0627\u0644\u0645\u064a\u0643\u0631\u0648\u0646\u064a (Surround) \u0639\u0644\u0649 \u0648\u0636\u0639 \u0627\u0644\u0628\u064a\u0636 \u0644\u062d\u0634\u0631\u0629 \u0628\u0633\u064a\u0644\u0627 \u0627\u0644\u0623\u062c\u0627\u0635<\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>MazenBufaur(\u00b9), Vili Harizanova(\u00b2) &amp; Nariman Al-Zugbi(\u00b9) (1).
