title: Temperature Effects on Reproduction and Pathogenicity of Pratylenchus coffeae and P. brachyurus and Survival of P. coffeae in Roots of Citrus jambhiri.
abstract: Optimum temperature for reproduction of Pratylenchus coffeae on Rough lemon, Citrus jambhiri Lush. was 29.5 C. Pratylenchus coffeae populations reached 7653 per g of root 2 months after initial inoculation with 140 nematodes. Maximum plant weight reduction was 38%; root weights were reduced by as much as 47%. Pratylenchus brachyurus significantly reduced plant and root weights but population sizes never approached those of P. coffeae. Pratylenchus coffeae survived in stored excised roots and were still infective after 4 months at temperatures ranging from 4.5 to 32 C.
