A parasite organism which works from the outside in. Living outside its host. A leech is an example.

Use of screen, traps, barriers, etc., as a method of isolating plants from the surrounding pests, or vise-versa.
Excrement (eX-kree-ment)
Feces, droppings, bodily wastes, very often a good sign of insect activity useful to scouts.
Exoskeleton (eK-Soh-skell-eh-ton)

Fauna (fAHw-Nah)

Feces (fee-Seez)
Excrement, droppings, bodily wastes, very often a good sign of insect activity useful to scouts.

Hormoligosis (horr-MOH-lee-goh-sis)
A process by which a pesticide-treated plant releases an abundance of free amino acids into its sap, making the plant more nutritious to the pest organisms feeding on its tissues, and resulting in a population explosion of certain pests (e.g., mites) after application.
Honeydew (hohn-nee-doo)
The waste, poop, excrement of certain soft-bodied insects. Ants and others are attracted to this clear, sticky substance.
Host (hohst)
The organism supporting an ecto- or endoparasite.
Hydroponic (hii-droh-PAWN-ick)
A growing technique using water as a way of nourishing plants. Hydroponic growing uses no soil, though it does often employ a medium of some sort, usually something inert such as perlite or rockwool.
Hyperparasite (hii-PERr-pahr-eh-syTe)
