Abstract

Different coloured plastic buckets (yellow, red, blue and white), filled with water were used as traps for adults of Tropinota squalida Scop. in apple orchards at El-Khatatba (El-Behaira Gover-norate) during seasons 2005 and 2006. The gen-eral mean numbers of adults/ trap were 6.0, 8.1, 14.4 and 24.1 in 2005 and 4.7, 6.7, 10.5 and 18.7 in 2006 seasons for white, red, yellow and blue traps, respectively. The general means for trap efficiency (two seasons) were 9.8, 13.7, 23.2 and 39.3 for white, red, yellow and blue traps, respec-tively. Two groups of white plastic cups, group filled with blue water solution and another group filled with water were used as traps and slung in apple trees. The general mean numbers of adults/trap were 8.1 & 7.5 for blue water solution and 5.8 & 5.2 for water traps during 2005 and 2006, respectively. The general means of trap effi-ciency (two seasons) were 36.8 and 25.9% for the above mentioned traps, respectively
