Reforestation in the arid zone depends on the successful propagation of trees. Vegetative propagation may serve as a good alternative to propagation by seed. This study was carried out in a nursery in Maiduguri, Borno State, Nigeria. The study was focused to determine the effect of different soil types on the rooting and growth of Delonix regia stem cuttings. The treatments consisted of three different soil types (river sand, top soil and a mixture of river sand + top soil + cow dung in a ratio 1:1:1). The experiment was factorially combined and laid in a complete randomized block design with four replications. The results indicated that soil mixture gave the higher results in all measured parameters followed by top soil, and least result was recorded in river sand.

The present work was carried out throughout two successive years (2010/2011 and 2011/2012) todetermine effect of different tree cardinal directions, leaflet parts, leaflet surfaces and frond stratums of date palm treeson distributionof Parlatoria blanchardii at Esna district, LuxorGovernorate. The obtained results showed a highly significant and significant differences between the population means at the four cardinal directions during the two years of study (2010/2011 and 2011/2012), respectively. However, the grand means were relatively higher at the east direction (102.8and 94.03 individuals per leaflet), followed by south site (96.26 and 88.79 individuals per leaflet). In contrast, west direction was the least infested by insect (66.43 and 83.03 individuals per leaflet). While, the north direction was moderately infested with this insect as mean (87.48 and 84.12 individuals per leaflet) for the two years of study, respectively. Also, the basalparts of leaflet was the most preference parts and highest infestation to this insect with mean (12.25 and 11.86 of scale per inch2), followed by themiddleparts ofthe leaflets with mean (10.25 and 10.05 of scale per inch2) for two years of study, respectively. While, the apical parts of leaflet was the least affected by insect with mean (7.10 and 6.93 of scale per inch2) during the 2010/2011 and 2011/2012, respectively. As regardingthe leaflet surfaces,the upper surface were heavily infested than the lower ones.The percentages of the pest population on the upper and lower leaflet surface were 71.36 and 28.64% during the 1st year (2010/2011). While, in the 2nd year of (2011/2012) were 71.19 and 28.81%, respectively.Concerningthe distribution of infestation on frond, the basal stratum of fronds received the highest population as mean (11.38 and 10.21 of scale per inch2) were determined depended on the upper basal surface of leaflets, followed by themiddlestratum of the frond as mean (7.99 and 7.79 of scale per one inch2) for two years of study, respectively. Infestation on theapical stratum of the frond was least population of this insect (6.62 and 6.46 individuals per inch2) during 2010/2011 and 2011/2012, respectively. Generally, it can be concluded from the current investigation that the insect population occurred on different tree directions and all parts and stratums of date palm trees on the all year round during the two years of investigation. P. blanchardiiprefers south eastern sides and upperbasal surface of leaflets where its population was always abundant all over the year.
