Watermelon ( C. lanatus var. lanatus ) is an important vegetable crop grown in the United States with an annual production of 2.1 million tons and a farm value of $435 million ( U.S. Department of Agriculture [USDA], 2007 ). Root-knot nematodes
Root-knot nematodes (RKN; Meloidogyne spp.) are an economically important pathogen on many agricultural plants and are the most commonly reported nematodes on vegetable crops in the United States ( Koenning et al., 1999 ). Because of environmental

Root-knot nematodes are widespread worldwide and cause significant reductions in the yield and quality of storage roots in sweetpotato ( Clark and Moyer, 1988 ). The worldwide distribution of root-knot nematodes (RKN), Meloidogyne Goeldi species
The southern root-knot nematode, Meloidogyne incognita (Chitwood) Kofoid and White, causes severe yield losses to pepper production in sub-tropical climates throughout the world ( DiVito et al., 1985 , 1992 ; Sasser and Freckman, 1987 ). In
