First Report of the Root-knot Nematode Meloidogyne incognita on Tomato in Cape Verde

Meloidogyne incognita is a serious pest of several economically important plants in tropical and subtropical regions. One such plant, tomato (Solanum lycopersicum L.), is one of the most widely grown vegetables on irrigated land in Cape Verde. In June 2015, tomato plants (cv. Savana) with symptoms of stunting, leaf wilting and poor fruiting, were recorded in a field in Achada Colaco, Santiago Island (15°06'35.3"N, 23°31'31.9"W). Roots of these plants were galled indicating the occurrence of root-knot nematodes. Detected nematodes were isolated and dissected from roots using standard procedures. Morphological and genetic studies revealed the presence of M. incognita. Female (n = 47) perineal patterns showed a high and squared dorsal arch composed of smooth to wavy striae; distinct lateral lines were absent. Stylet had cone curved dorsally, knobs broadly elongated and set off from the shaft. Males’ heads possessed a high and wide head cap with centrally concave labial disc. The measurements of males (n = 5)...
