Adsorption- The adhesion of molecules of a substance to the surface of another substance, typically forming a thin layer.

Allogrooming - A form of mutual grooming in social insects and animals. Observed in ants, termites and other social insects, used to promote good hygiene in a nest.

Bait Station - Small structure with openings allowing entrance of the insects, and containing an attractive bait and insecticide

Biopesticide - Microorganisms used in pest control. Development is underway for effective broad-range pathogen.

Conidia - Asexual, non-motile spores of a fungus. Also called mitospores

Deterrent - Substance that is avoided by foraging insects. Can be sprayed on to structures and acts to prevent structure damage by detering insects from using the material for food. ex. Timber

Entomopathogens - A pathogen capable of invading an insect and killing it. ex. Fungi

Epizootics- A type of disease that appears in an animal population as a newly recorded case. It may also spread much faster than what was previously expected.

Exoskeleton - Found in insects and crustaceans. Hardened outer latyer of cuticle composed of chitin.

Hemimetabolous - Incomplete metamorphosis in insects consisting of an egg stage, a variable number of nymph stages characterized by a slight increase in body size and specialized development, and finally an adult stage.

Mycelium - Vegetative part of the fungus, consisting of branched hyphae

Necrosis - Death of tissue

Phytopathogen - Any physical or chemical agent that is able to cause disease a plant, eventually leading to death.

Repellant - Prevents damage to structures by being unattractive to foraging insects. see Deterrent.

Synergistic - Acting together

Rusts- A type of fungi that contains a unique life cycle with the creation of five different spores. It is also a very good herbicide because of this. For more information on Fungal Rusts

Germination- The start of an active life cycle once starting from a spore.

Germ Tube- An active way that a spore can infect a host. It is a process that has direct connection with the internal cells of the host and an injection of pathogenic cells.

Appressoria- The spot of infection, and the creation of specialized cells that enable further infection to occur. These specialized cells are at the tip of the hyphae and enables the pathogen to penetrate the host to cause infection. See Appressoria

Stoma- A leaf structure that opens and closes that enables the leaf to go through the process of gas exchange.

Mastigomycotina- A subdivision of fungi that are in the class; Oomycetes and have characteristic motile spores and gametes.

Zygomycotina- A subdivision of fungi that are also sometimes referred to as bread molds. They can reproduce both sexually and asexually.

Ascomycotina- A subdivision of fungi that are also referred to as sac fungi. They contain 4-8 ascospores in each of their ascus during the sexual stage.

Deuteromycotina-A subdivision of fungi that are also referred to as fungi imperfecti. Their asexual stage has only been identified and research is trying to uncover a possible form of sexual reproduction.
