First report of Microcera coccophila on citrus purple scale (Lepidosaphes beckii) in Iran and its probable potential for biological control

On Jan 2012, a fungus was collected on orange fruit from Sumehsara township, Guilan province, Iran that specifically colonize scale insects (Lepidosaphes beckii). This fungus produce sporodochia that were orange to pale orange and synnemata like, culture was slow-growing on PDA (growth rate 8.3 mm after 3 days and 25°C), without microconidia and chlamydospores, Macroconidia cylindrical, slightly curved especially towards the apexes, large (84-96 × 6 µm), with 7-10 transverse septa and with foot cell. On the basis of above characters and after comparison with relevant literature, the isolate was identified as Microcera coccophila. This species has been reported from Iran as Fusarium coccophilum on Gleditschia caspica, previously. So it is the first report of Microcera coccophila on scale insect (Lepidosaphes beckii) in Iran. As in nature this species occurs as a parasite of scale insects and we observed it especially on Lepidosaphes beckii on the examined sample, maybe the species has potential for biological control of Lepidosaphes beckii especially in north provinces of Iran.
The isolate is available in mycological culture collection of University of Guilan (accession number 9). Further studies on this fungus especially on determination of its efficiency, specificity and its adaptation with environmental conditions of North of Iran are recommended.
