Campbell, is one of ten volumes covering the "Developmental Biology Conference Series of 1956," organized by Paul Weiss and held under the auspices of the National Academy of Sciences-National Research Council. The purpose of thi...
متن کاملInsect physiology: The emerging story of ecdysis
The discovery of a new insect peptide hormone that triggers ecdysis - shedding of an old cuticle - has revealed hidden layers of intricacy about an insect behavior previously thought to be mediated by a single neuropeptide.
متن کاملInsect Sterol Nutrition and Physiology: A Global Overview
Unlike most animals, insects lack the capacity to synthesize sterols that are required in lipid biostructures, as precursors to important steroid hormones and as regulators of developmental processes. Therefore insects must acquire sterols from their diet. Hundreds of different sterols have been identified and the review starts by documenting the occurrence of sterols in different insect foods....
متن کاملInsect vectors of Leishmania: distribution, physiology and their control.
Leishmaniasis is a deadly vector-borne disease that causes significant morbidity and mortality in Africa, Asia, Latin America and Mediterranean regions. The causative agent of leishmaniasis is transmitted from man to man by a tiny insect called sandfly. Approximately, 600 species of sandflies are known but only 10% of these act as disease vectors. Further, only 30 species of these are important...
متن کاملTeaching insect retinal physiology with newly designed, inexpensive micromanipulators.
In this article, we detail how to produce two inexpensive micromanipulators that offer high precision (approximately 25 microm) along a single axis of movement. The more expensive of the designs provides improved versatility along multiple axes. Both manipulators offer substantial savings over commercially available micromanipulators with comparable capabilities. Plans and instructions are give...
