REXHEP UKA | | Publisher : | | | Bridge Center | | Article URL : |  | | | Abstract : | | | Since the cultivation of fruit trees has been increased in the
recent years, as is presented by INSTAT, in order to have a good fruit
production and fruit quality, there is a need for in-depth studies on
insect pests to establish effective methods for fruit tree protection
through an appropriate strategy. During this study, an inventory of
scale insects that affect and damage stone fruit trees, for example:
Parthenolecanium corni (Bouché) was found in peaches, apricots,
plums and almonds; Parthenolecanium persicae (Fabricius) was found
in peaches, apricots, plums; Quadraspidiotus ostraeformis (Curtis)
was found in plum, etc. The study has been conducted in stone fruit
tree orchards of the Tirana region and adjacent areas from 2015, 2016,
and continuing in 2017 in order to determine harmful scale insect
species and their natural enemies. Collection of insect pests was
carried out in certain periods throughout the year, mainly during the
vegetation period but also in the dormancy period. Plant samples were
transferred to plastic bags and brought to the laboratory. Some of the
collected scale insects were preserved in 70 % ethanol for subsequent
identification. Inside there were placed the label with code number and
key data. Insect pests newly collected or newly dead are placed in a test
tube with internal diameter of at least 7 mm, length 40 mm and round
base with preservatives alcohol content 90-96 %. Collecting and
preserving techniques used were based mainly on the method of HilleRisLambers (1950). Through this inventory, there were defined
kinds of scale insects that affect stone fruit trees. This study was
conducted in seven representative areas of the Tirana region,
respectively: Laknas, Berzhita, Maminas, Ndroq, Preza, Tapiza and
Vora. Among scale insect species that were most prevalent in the
Tirana region, which were found in all areas of study in stone fruit
trees include: Pseudaulecaspis pentagona (Targioni-Tozzetti),
Quadraspidiotus perniciosus (Comstock), Epidiaspis leperii (Signoret),
Parthenolecanium persicae (Fabricius), Quadrispidiotus ostraeformis
(Curtis), and Pseudaulecaspis pentagona (Targioni). There has been
identified the entomophag species of scale insects in stone fruit trees in
Tirana region. Further inventory of insect pests of stone fruit trees, in
the future will help to implement in the most appropriate time of the
measures to suppress them. | | Keywords : | | | scale insects, inventory, stone fruit trees, entomophag
