Insect specialized

Table 5.2 Examples of studies showing attraction of insects specialized on Brassicaceae by isolated glucosinolate hydrolysis products. NCS, isothiocyanate CN, cyanide (= nitrile).

The different areas of scientific study are called disciplines, or fields of knowledge. Each addresses a specific area of knowledge. Once you begin to study one discipline, you ll find you can go deeper, and narrow your studies to an even smaller area of that science. For example, some entomologists— who study insects—specialize, spending their whole careers studying just caterpillars, or butterflies, or ants.

There have been many reports of insect pest species developing resistance to OP insecticides, to the extent that control of the pest has been lost. A detailed account of resistance lies ontside the scope of the present book, and readers are referred to specialized texts by Georghion and Saito (1983), Brown (1971), and Otto and Weber (1992). A few examples will now be considered that illustrate the mechanisms by which insects become resistant to OP insecticides.

Also, special vectors allowing expression in both insect cells and mammalian cell cultures from the same vector (pMamaBac [11] andpBacMam [12]) were described, though the amount required for mammalian transfection with one of these vectors is twofold higher than for insect cells, which makes it applicable only for assessment of suitability for a certain cell culture. 

For most people, BL is represented by the flash of the firefly or the phosphorescence that frequently occurs on agitating the surface of ocean water. Chemical excitation, luminescent reactions occurs in almost all zoological kingdoms (bacteria, dinoflagelates, Crustacea, worms, clams, insects, and fishes) except higher vertebrates BL is not found in any organisms higher than fish. In most cases this phenomenon occurs within specialized cells called photocytes [3-5], As shown in Table 1, BL occurs in many terrestrial forms but is most common in the sea, particularly in the deep ocean, where the majority of species are luminescent [6],... 

Highly toxic substances, such as cyanides, are sometimes feeding cues and stimulants for specialized insects. For example, instar larvae of the southern armyworm (Spodoptera eridania) strongly prefer cyanogenic foods, such as foliage of the lima bean, a plant with comparatively elevated cyanide content — up to 31 mg/kg in some varieties — in the form of linamurin (Brattsten et al. 1983). Feeding was stimulated in southern army worms at dietary levels up to 508 mg KCN/kg... 

Animal facilities have traditionally been under the purview of the scientist. However, there are special safety and health considerations which should be involved in the design of individual animal rooms. These facilities may, also, include housing for insects, parasites, etc.
