肾形线虫Reniforme nematode是为害蔬菜重要病原线虫之一,寄主范围广泛,分布普遍.通过在广州地区连续三年调查和室内接种试验得知,可寄生于11科29种蔬菜,寄生率高的有豆科、茄科和葫芦科中的各种蔬菜,其中苦瓜、节瓜、生菜、西洋菜、葱、蒜、姜等8种为首次报道。肾形线虫以年青雌虫从寄主植物幼根的伸长区侵入为害,一个侵染点常只有一条线虫侵染,侵染点周围细胞褐变。线虫在土壤中的垂直分布,主要在0—20cm耕作层。
Reniforme nematode is one of the important pathogenic nematodes that infest vegetables and has a wide range of hosts and widespread distribution.By three years of investigation and indoor inoculation tests in Guangzhou, Reniforme nematode can be parasitized in 11 families and 29 kinds of vegetables with high parasitism Leguminosae, Solanaceae and Cucurbitaceae in various vegetables, including bitter gourd, melon, lettuce, watercress, onion, garlic, ginger and other 8 kinds of the first report. Nephrophagous nematodes invade the young female from the elongation zone of the host plant’s root, with only one nematode infested at one site of infection and browning around the site of infection. Vertical distribution of nematodes in the soil, mainly 0-20cm tillage layer.
