Heterorhabditis bacteriophora

Heterorhabditis bacteriophora

Kingdom: Animalia
Phylum: Nematoda
Class: Secementea
Order: Rhabditida
Family: Heterohabditidae
Genus: Heterorhabditis
Species: bacteriophora

This nematode was first discovered in Brecon, Australia inside of a caterpillar. This nematode has a life cycle that consist of egg, four juvenile stages, and then the adult stage. These nematodes go into their host during their juvenile stages, by sliding through pores and openings that the host may have. They grow, reproduce, and feed on the host until there is no more and then move on to another host. These nematodes not only eat caterpillars, but they also eat each other. When the adult reproduces, it releases some of its eggs, but also holds some of its eggs inside of its body. When the eggs inside the parent nematode hatch, they begin to feed on the parent nematode till it is no more, kind of like a virus. These nematodes are used as pesticides on farms in order to get rid of any insects that may harm crops or lower the soil quality. They reproduce quickly so it is definitely a useful tool in the farming industry.
