Effects of the Harvest Method on the Infestation of Chestnuts (Castanea sativa) by Insects and Moulds

摘要: Chestnuts were collected either every 7 days from suspended nets used to intercept the fruits, 2 ground or ground. Nuts visually inspected after collection for presence of exit holes chestnut weevil (Curculio elephas) and moth (Cydia splendana), 20 nuts per sampling tree bisected assess fungal colonization. Apparently healthy incubated at 24� C 70–80% relative humidity 21 days. All incubation examined insects moulds. The harvest method did not have a statistically significant effect on moulding insect infestation except Amphiporthe castanea. This vertically transmitted endophyte was less frequently isolated fruits black rot fungus Ciboria batschiana occur in chestnuts intercepted nets, but difference significant. frequency colonized by C. low general probably due hot dry summer 2003.
