The seasonal abundance of the seychelles fluted scale, Icerya seychellarum (Westwood) (Monophelibidae: Hemiptera) was studied for two years (September first, 2012 until mid-August, 2014) on mango trees at Qaluybyia Governorate.
The obtained results showed that I.
seychellarum has four peaks and presence of three overlapping generations in both years under field conditions.
Over the first and second years the first generation (winter/autumn) started from September first until mid-February, 2013 as the terminal of the first generation (marked by maximum population of adult females).
The following count showed that most of these females were in ovipositing stage in a much-synchronized fashion (which indicates the optimal condition for the development of I.
seychellarum.
The second generation (spring) started from mid- February and continued until the date of mid- May 2013.
Therefore, the mid- May was considered as the end point of this generation and start point for the third generation (summer) which continued to the next year.
Reviewing proved that the obtained results, it could be that the first generation continued over 165 days, also the second generation continued 90 days compared with the third one which continued 90 days.
Also, there were positive relationship between metrological factors and the total population of I.
seychellarum (The higher the temperature, the greater total population of I.
seychellarum, while the lower the temperature, the lower total population of I.
seychellarum).
Four peaks of I.
seychellarum total population simultaneous with moderate and high temperatures.
While the low temperatures (from December first until the end of February) the population of I.
seychellarum was low due to its hibernation as adult females.
The data showed simultaneous occurrence of the total population of I.
seychellarum and its associated predator, Rodalia cardinalis (Mulsant) (Coleoptera: Coccinellidae)
