ABSTRACT
Altitudinal distribution and damage intensity of Cypress aphid on Cupressuslusitanicaof different age classes were investigated at SUA Training Forest. The abundance of natural enemies of Cypress aphid different age classes (young 1-10years, middle 11-25 and old >25years) and altitudinal ranges (lower 1700-1930 m.a.s.l, middle 1931-2125 m.a.s.l and upper 2126-2300 m.a.s.l) was also determined. Systematic sampling was used, whereby every 5th tree along the row of the study plot/block was considered as a candidate. Five shots in the lower, middle and upper crown part of the selected tree were randomly cut and put in labelled zipped plastic bags for laboratory assessment of the aphids and natural enemies. Results from this study indicated that Cypress aphid was un-equally distributed throughout the altitudinal ranges and age classes. The abundance of Cypress aphid per twig was 19.6, 24.9 and 33.7 individuals for lower, middle and higher altitude respectively and was significantlydifferent (p
