Introduction of the destructive agents affecting wild almond Amygdalus scoparia forests in Koh-Siah Dashti area in Bushehr province
Wild almond (Amygdalus scoparia Spach) is one of the most valuable plants in Iran- Tourani mountainous areas in Central, South, East and West part of the country. This study was carried out to collect and identify primary agents in particular pests and diseases causing decline of almond forests in Koh-Siah Dashti area in Bushehr province during 2009-2010. Sampling procedures for pests’ incidences was performed regularly on wild almond trees. Larval and immature pests’ stages were transferred to the laboratory for rearing. Plant pathological studies were undertaken in lab conditions to identify diseases affecting wild almond through culturing, isolation and purification of pathogens and provide ultimate control procedures. The results showed that the most important pests of A. scoparia were root beetles Capnodis carbonaria Klug scales Eulecanium persicae Fabricius, almond seed wasp Eurytoma amygdali Enderlein, rodents as Hystrix leucura Sykes and bark beetle Scolytus amygdali Geurin-Meneville. The pathogens that separated and identified were Fusarium proliferatum Matsushima, Alternaria alternate Keissl, Aspergillus parasiticus and chaetomium sp. Kuntze. Of all important human induced disturbances of almond forests, industrial developments and animal grazing could be cited. Charcoal making, arson, road construction and mining activities are next issues to mention At the end control methods to restore wild almond communities are provided.
