| Abstract | ||
| The soft scale insect kilifia acuminata (Signoret) (Hemiptera: Coccidae) is one of the main insect pests infesting mango trees and caused the damage for leaves and fruits. The population density of the soft scale insect k. acuminata during the first year of study 2014/15 recorded 6 peaks and the highest peak was 1539 indiv.on 27th of March, 2015. While recorded 5 peaks during the second year 2015/16 and the highest peak was on 17th of June 2016 and represented by 1178 indiv. The highest average number and percentage in the first year was recorded during autumn season and represented by 1023.1 indiv. /100 leave (30.2%), while the highest average number and percentage was recorded during spring and represented by 994.8indiv./100 leaves (29%) in the second year. The highest average number of the soft scale insect K. acuminata were recorded in the south direction during the two successive years 2014/15 and 2015/16 and represented by 225.9+19.6 and 241.4+18.3 indiv. /100 leaves, respectively. On the other hand, the lowest average number were recorded in the North direction and represented by 105.4+16.1 and 74.8+6.2 indiv. /100 leaves, respectively. Statistical analysis showed that, a highly significant differences between the different directions, during the two successive year of study. | ||
