Meloidogyne haplanaria is a newly described species from Texas that attacks peanut. Common bean, garden pea, radish and soybean were confirmed as hosts in greenhouse tests. Cowpea and eggplant were poor hosts, supporting 40 eggs/g roots 8 weeks after inoculation. Reproduction of M. haplanaria varied among 10 soybean cultivars, ranging from 160 to 7,000 eggs/g roots 14 weeks after inoculation with 10,000 eggs/pot. The M. arenaria-resistant peanut cultivar NemaTAM was also resistant to M. haplanaria , but resistance in tomato to Meloidogyne spp. conferred by the Mi gene was not effective against M. haplanaria.
