Definition: Aranciocystis is a type of parasitic nematode that feeds on plant material, typically in the form of seeds or roots. It's found in various parts of the world, including tropical and subtropical regions. The life cycle involves an adult larva feeding on plant tissues, which then secrete amylase enzymes to break down the plant cell walls into a nutrient-rich exoskeleton. This process is crucial for the larval stage as it provides nutrients for further development.
