arthropods, entomologyThe adults of Donacia simplex are found on the roots of aquatic plants during the winter. Oxygen diffuses from the gas spaces in the roots into the gas-filled cocoons through the root scar. The root scar slows down the diffusion of oxygen into the cocoons. During the ...
arthropods, entomology, insectsWhen totally submerged beneath the surface of the water, Belostoma and Ranatra respire by means of air stores which adhere to their bodies and which communicate with the spiracles. The mesothoracic spiracle lies between the prothorax and mesothorax; the metathoracic ...
Field ecological studies and molecular techniques can be used to not only better understand how these types of physiological mechanisms have allowed unique ways for aquatic insects to respire, but also understand how they have adapted to flowing waters as well as developed control strategies for pest...
