Abstract
Survey on olive insect pests during 3 seaons (2014-2015-2016) to identify the species
which infested the olive trees in Burg El-Arab special 4 cultivars (Shemlali-Picual-Tophahy-
Kalamata) and determined the sensitive cultivar to some pests. Also, used the Mc Phail trap to
attracted the olive fruit fly during the season.

the survey of olive insect pests was done at the experimental farm of city of scientific
research and technological applications during 3 seasons April 2014 up to November 2016.
The collective data revealed 9 main insect pests related to 5 orders Hemiptera (4
spices),Homoptera(1 spices), Lepidoptera(2 spices), Coleoptera (1 spices)and Diptera(1 spices).
Or: Hemiptra, Fam:Diaspididae
1) Aspidiotus nerii
1- The Infestation rate with A.nerii :
The data collected in two seasons (2015-2016),on shemlali cultivar the maximum rate in
October with(34% - 51%)in 2015 and 2016, respectively. On Picual cultivar the maximum rate
in November with(23%)but the second season was in April(39%). On tophahy cultivar the

kalamata cultivar the maximum rate occurred in October(38.2%), While in 2016 was (26.1%)in
August .
2- Effect of cardinal directions on the distribution of A.nerii:
on shemlali cultivar the highest rate occurred in East direction (31.2%)in 2015 but in 2016 it was
in North with(45.8%). On Picual cultivar in 2015, the highest rate recorded in East direction
(32.8%) and 2016 it was in North direction(50%). On tophahy cultivar the highest rate (27.5%)

cultivar the highest ratio was in East (38.9%)but it was in South direction in the second season
with (46.2%).
3- Effect of olive cultivar on the rate of infestation by A.nerii:
The highest grand total observed in tophahy (37.48%) after that shemlali with (29.43%)
then kalamata with (18.25%) and the least was picual with rate(14.82%).
2) Leucaspis riccae
1- The Infestation rate with L.riccae:
During season of 2016, on shemlali cultivar the maximum rate was (34.9%) in September.
On Piccual cultivar the highest rate was (43.7%) in October while in tophahy cultivar it was
(33%)in November as the maximum rate. finally in kalamata cultivar the maximum rate was in
