Meloidogyne hapla was detected for the sixth time in Ecuador; however this species was recorded for the first time infesting a tree tomato (Solanum betaceum Cav.) crop in this country. It represents the first record for this species in the Tungurahua province, Ecuador. These results confirm a wider geographical distribution pattern of this species in Ecuador and a wide range of host species. The i...... hiện toàn bộ
