“…There is clear evidence that climate change is altering the distribution, incidence and intensity of animal and plant pests (Rasekh et al, 2011) For example, it has been reported a dramatic increase in enquires regarding to P. floccifera. This pest is frequently intercepted on imported plants, most often on Camellia from France, Italy, Netherlands and New Zealand.…”

The Sago palm infested with different scale insects, among them the cottony camellia scale, Pulvinaria floccifera (Westwood), is the most serious pest of Sago palm. This study was conducted to demonstrate the number of generations of this pest and the effect of parasitic and meteorological factor on its population. The present study was carried out in the Farm of Faculty of Agriculture, Assiut university, during two successive seasons of 2013/2014 and 2014/2015. The obtain results of both seasons showed that half monthly observation of this insect had one peak of seasonal activity per year, which was recorded in the 1 st of March. The highest percentage of the total monthly mean count was also recorded during March. (20.69, 19.09 % out of the total year count). The pest has one generation in each of the tow studied seasons. Concerning, the monthly variation rate in the population (M.V.R), the obtained results showed that the favorable times for this insect were from November to May of the first year and October to June of the second year. One parasitoid species was only found Microterys flavus (Howard). The percentages of parasitism ranged from 5.81% in October to 17.65% in August and 6.01% in April to 12.99% in July during the first and the second season of study.
