Methods are provided for the genetic control of pathogen infestation in host organisms such as plants, vertebrate animals and fungi. Such methods utilize the host as a delivery system for the delivery of genetic agents, preferably in the form of RNA molecules, to a pathogen, which agents cause directly or indirectly an impairment in the ability of the pathogen to maintain itself, grow or otherwise infest a host plant, vertebrate animal or fungus. Also provided are DNA constructs and novel nematode nucleotide sequences for use in same, that facilitate pathogen resistance when expressed in a genetically-modified host. Such constructs direct the expression of RNA molecules substantially homologous and/or complementary to an RNA molecule encoded by a nucleotide sequence within the genome of a pathogen and/or of the cells of a host to effect down-regulation of the nucleotide sequence. Particular hosts contemplated are plants, such as pineapple plants, and particular pathogens are nematodes.
