Endopterygota Holometabolous insects undergo significant morphological changes during their development. The larvae (mostly grub-like) are very different in appearance to the adults and undergo metamorphosis into the adult form via a non-feeding pupal stage where the body tissues are broken down and rearranged into the adult morphology. 2.

and brain. The larva of Echinococcus develops into a spherical fluid-filled cyst called a hydatid cyst. This cyst can reach 150mm in diameter‚ contains numerous secondary cysts (germinal epithelium) or broad capsules in which thousands of future larvae (called protoscolices) develop usually in the liver and lungs. If the hydatid cyst ruptures‚ the brood capsules can spill out of the cyst‚ metastasize to other sites‚ and develop into a hydatid cyst and is responsible for hydatid disease (hydatidosis)

observe the role of diet during stress response at cellular and metabolic levels in fruit flies. Before the research began they first had to collect and harvest the flies for the experiment. Eggs were collected and once they had hatched and finished larvae development‚ the virgin flies aged until ready to be tested. The flies used had to be the same age and were maintained under the same laboratory conditions with different nutritional diets. This experiment would measure desiccation‚ starvation‚ chill-coma

This type of characteristic helps kill the Prickly Pear safely instead of using chemicals. If somebody
