| 實物特徵: | Planting distance and the intensity of Dioryctria horneana (Lepidoptera: Phycitidae) attack on Pinus cubensis in Guatanamo, Cuba. The lepidopteran Dioryctria horneana (Phycitidae) affects Pinus cubensis. For three years startiong February 2009 we studied the effect of planting distanced on the attack. We used three plots of 30 trees each at several planting distances (2x2m; 2,5x2m and 2,5x2,5m). There were three repetitions with a yearly basis. A 2,5x2,5m produced the lowest attack rate.KEY WORDSDistance plantation, plantations, Pinus cubensis, plague. |
