| Abstract: | Sugarbeet cyst nematode (Heterodera schachtii) is one of the main pathogens that seriously harm sugar beet production, causing serious economic losses every year, and it is also an important quarantine pest in China. In this study, 29 varieties of 16 crops, including Brassicaceae, Solanaceae, Cucurbitaceae, Malvaceae, Fabaceae, Amaranthaceae and Poaceae, were artificially inoculated in an isolated greenhouse, and their main host range and life history were investigated. The results showed that the second juveniles of sugarbeet cyst nematode could infect the roots of 25 varieties of 14 crops except wheat and corn. White females and cysts formed in the roots of 16 varieties of crops, such as sugar beet, spinach, tomato and all Brassicaceae plants. The life history investigation showed that the white females formed at 15 d and 12 d after inoculation of sugar beet and rape, and the cysts were found 30 days later, while on the root system of watermelon, the second juveniles remained undeveloped and could not complete their life cycle. The above results suggested that sugarbeet cyst nematode could parasitize sugar beet, spinach, tomato and cruciferous crops, but there were some differences in their life histories on different hosts. The results provide a theoretical basis for non-host rotation control of sugarbeet cyst nematode. |
