Natural enemies/biotic agents (predators and parasites)
a. Predators:
- They consume several to many prey over the course of their development, they are free living, and they are usually as big as or bigger than their prey.
- Common predators include lady beetles, rove beetles, many ground beetles, lacewings, true bugs such as Podisus and Orius, syrphid fly larvae, mantids, spiders, and mites such as Phytoseiulus and Amblyseius.
Â
b. Parasitoids (parasite-like):
- A parasitoid is an organism that spends its larval stage in or on another organism, also known as a host.
- Host death is what makes parasitoids different from other parasites, who do not necessarily kill their host, such as ticks or lice.
- The adult parasitoid leaves the host to find mates and new hosts to lay her eggs.
- Bathyplectes, Trichogramma, Encarsia, Muscidifurax, Spalangia, and s are some of the most important parasitoids studied or used in agricultural systems.
