Reported median body size for this species (Length mm; width micrometers; weight micrograms) - Click:
Reported originally from peanut in Texas but determined to have a wide host range when tested on other plants. More recently in Florida infecting Mi-gene root-knot-resistant tomato plants and in California on the roots of pitcher plants in a botanical garden nursery (Benmdezu et al., 2004; Eisenback et al., 2003; Joseph et al., 2016; Subbotin, 2021).
Sedentary endoparasite.
Feeding site establishment and development typical of genus.
Type Host:: Peanut (Arachis hypogaea).
Ecophysiological Parameters:
Root-galling of infected plants ate the type locality in Texas was similar to that of M. hapla, with small galls and increased numbers of secondary roots. However, esterase and malate dehydrogenase phenotypes and reproduction on a standard set of host differentials indicated that the population differed from other Meloidogyne species (Eisenback et al., 2003).
M. haplanaria is virulent on tomato cultivars with the Mi-gene; it has a shorter life cycle than M. enterolobii , which is also virulent on Mi-gene cultivars, and can infect, reproduce, and damage plants with either homozygous or heterozygous resistance (Espinoza-Lozano et al. 2022).
