Immature Stages of Insect Endoparasites
While dissecting insects, one may encounter the immature stages of insect parasites. These entomophagous (or entomogenous) insects belong to several orders and demonstrate a wide variation in habits and biology. They are sometimes called parasitoids rather than parasites because they develop at the expense of a single host, which is killed as a result of the attack. Insect parasites may feed and develop inside the insect host (endo-parasite) or they may devour the host from the outside (ectoparasite). Only those of the former category will be discussed in this section. Both groups are extremely important regulators of insect populations. Many adult forms serve a predatory role by inflicting wounds and feeding on the hemolymph of insect pests or devouring the entire prey.
