The population density of the mango shield scale, Milviscutulus mangiferae (Green) (Hemiptera: Coccidae) had been studied during two successive seasons from January 2018 to December 2019 in response to the climatic factors on mango trees at Abu Suwair district, Ismailia Governorate.
The obtained results indicated that M.
mangiferae active all the year with different individual numbers, the total population density of M.
mangiferae was relatively more abundant during the first season, 2018 (585.78 individuals/leaf) than the second season, 2019 (527.85 individuals/leaf).
Obtained data showed there were three peaks of activity on mango trees for total population in January, July and November represented by 46.78, 63.85 and 87.69 individuals / leaf and in January, June and November represented by 44.49, 55.98 and 90.07 individuals / leaf for two seasons, respectively.
There was highly significant negative relation between daily mean maximum temperature and total population density; while there were highly significant positive relation between daily mean minimum temperature and total population density of M.
mangiferae in the two seasons.
On the other hand, daily mean relative humidity with total population density gave significant positive relation in the first and second seasons.
The percentages of explained variance (E.V.
%) indicate that all tested variables were responsible on variability on the total insect population by 84.03 % and 83.53 % during the first and second seasons, respectively.
