Double-stranded RNA (dsRNA) molecules of viruses are found in nature at a very high frequency. Their detection in plants and fungi has been carried out with difficulty due to the complicated dsRNA extraction techniques used commonly which includes phenol-chloroform extractions. In this study, an extraction method for isolation of dsRNA is described that is(More)
Rhynchophorus ferrugineus is considered the worst pest of palm species, and few natural enemies are reported for this parasite in its area of origin. Here, we report the first recovery of the entomopathogenic fungus Metarhizium pingshaense associated with R. ferrugineus from Vietnam. The morphological, biochemical, and toxicological features of this strain(More)
The natural spread of virus-induced hypovirulence is highly involved in the recovery of blighted chestnut stands and orchards in Italy and in Europe. The potential role of corticolous mites as vectors of hypovirulence in blighted chestnut Castanea sativa (Mill.) stands was pointed out in previous reports. Here, by using RT-PCR, mycovirus Cryphonectria(More)
The natural spread of hypovirulence in Cryphonectria parasitica (Murr.) Barr. occurs in chestnut (Castanea sativa Mill) stands and orchards in Italy and other European countries, leading to spontaneous recovery of the diseased trees. Little is known about how hypovirulence spreads in chestnut stands but various corticolous mite species frequently detected(More)
