what is insect bioidicator?

Any biological species or group of species whose function, population, or status can be used to determine ecosystem level or environmental integrity. An example of such a group of organisms is copepods and other small water crustaceans present in many water bodies.\n\nCopepods are a group of small crustaceans found in the sea and nearly every freshwater habitat. Many species are planktonic, but more are benthic, and some continental species may live in limno-terrestrial habitats and other wet terrestrial places, such as swamps, under leaf fall in wet forests, bogs, springs, ephemeral ponds and puddles, damp moss, or water-filled recesses (phytothelmata) of plants such as bromeliads and pitcher plants. Many live underground in marine and freshwater caves, sinkholes, or stream beds. Some copepods are parasitic and attach themselves to fish, sharks, marine mammals, and many kinds of invertebrates such as molluscs, tunicates, or corals.\n\nCopepods form a subclass belonging to the subphylum Crustacea (crustaceans). Some authors consider the copepods to be a full class. The group contains ten orders with some 14,000 described species. A scientist that studies copepods is a copepodologist.\n\nCopepods are very important food organisms for small fish, whales, and other crustaceans such as krill in the ocean and in fresh water. They are typically 1-2 mm long. They feed directly on phytoplankton, catching cells singly. Some scientists say they form the largest animal biomass on earth. They compete for this title with Antarctic krill (Euphausia superba).\n\nCopepods are sometimes found in the public mains water supply, especially systems where the water is not filtered, such as New York City and Boston, Massachusetts. This is not usually a problem in treated water supplies. In some tropical countries, such as Peru and Bangladesh, a correlation has been found between copepods and cholera in untreated water, because the cholera bacteria attach to the surfaces of planktonic animals. The risk of cholera from infected water can be reduced by filtering out the copepods (and other matter), for example with a cloth filter.\n\nMany species have neurons surrounded by myelin, which is very rare among invertebrates (other examples are some annelids and malacostracan crustaceans like palaemonid shrimp and penaeids). Even rarer is the fact that the myelin is highly organized, resembling the well-organized wrapping found in vertebrates (Gnathostomata).\n\nSome copepods are very evasive and can jump with extreme speed over a few millimeters (warning: takes some time to load to the correct speed):\n\n \nSlow-motion macrophotography video (50%) of juvenile Atlantic herring (38 mm) feeding on copepods - the fish approach from below and catch each copepod individually. In the middle of the image a copepod escapes successfully to the left.This scene was scanned with the ecoSCOPE, an underwater high speed microscope. Because clupeids (herrings) and copepods are both significant in terms of global biomass, this is the first record of what is one of the largest carbon flows of any animal food-chain transition in the oceans. It is a predator / prey relationship running at extreme speeds, with chances for both sides. Very little is known about the details, in spite of its importance for global processes, because copepods are difficult to keep in the laboratory and lose most of their escape capacity, and herring are very fast, alert and evasive organisms and flee normal camera systems or SCUBA divers. Oceanographers point out the importance of learning more about the influences of physical parameters, such as light, pollution or temperature, or the effects of hunting in a swarm. This copepod-herring relationship has implications for the fate of carbon in marine systems. If the copepod 'wins' (escapes), much carbon will sink with its fecal pellets into the depth of the oceans (see biological pump), sequestering carbon dioxide in the benthos. If the herring

biomass, bugs & water - when biological materials are mixed with microbes and water, the microbes will "eat" the biological material and release bio-gas.  If the microbes are anaerobic, you must prevent air from getting into the system.  If they are aerobic microbes, you may need to aerate the system.

Biotin is essential in metabolism.  Biotinidase makes biotin available to the body, by isolating it from food proteins and recycling it from cellualar proteins.  Many areas require the test.  One in 60,000 are affected, and it can be treated with biotin supplementation.

Entomology is the scientific study of insects. Insects have many kinds of interactions with humans and other forms of life on earth, so it is an important specialty within biology; unlike many other fields however, entomologists include both persons studying insects for their own sake, and those employed by commercial concerns interested in the control of insects.

Hmmm...wow...a VERY general question.  This is out of my field, but your other questions were so engaging I decided to see what else you have asked...\n\nFor the first one (how do they thrive/what modifications do they have). I am going to list things insects all have in common and that kill them when things go wrong with these systems:\nQ1:\n1) A chitinous exoskeleton, usually with a waxy covering that conserves water and provides mechanical protection.\n2) A system of spicules that enables oxygen/CO2 exchange without having to resort to an overly flexible out membrane keeping that mechanical protection sound. \n3) Segmented bodies and legs to allow greater flexibility of movement than is achievable solely with a segmented exoskeleton\n4) Wings for flight or additional mechanical protection\n5) Rudimentary circulatory system (this one might not qualify since I bet their ancestors had something like this too.)\n\nQ2:\nThere are a LOT of kinds of neoptera and I don't know much evolutionary biology so I will not attempt that one. Probably one trend has to do with the falling partial pressure of oxygen over the past few hundred million years and the guys getting smaller to cope. They all have flexible wings.  I dunno what else.  Sorry.\n\nQ3:  Compare flies to butterflies/moths/skippers.\nCommonalities: all 4 wings have flight function; larval stage that pupates; adults have tubular mouth parts\nDifferences:  antenna, scaled wings. \nThat is a start anyway. \n\nQ4:  Similarities: Chitinous exoskeletons, segmented bodies (but different numbers of segments), jointed legs, \nDifferences: wings vs. more legs, compound vs. simple eyes, pupation/metamorphosis vs. nymphal stages\n\nQ5:  Ecto means outside, and everyone know what parasitic means, so this would include lice, fleas, maybe mosquitos (they only suck blood for egg laying, you know), certain kinds of flies and true bugs.  They mostly live on blood, but I think some eat dead skin.  Geez, what else CAN you eat living on the outside of a critter?\n\nWhew.  Tough.

Very minute claws on the feet that allow them to grip. Some insects actually have a sticky substance on their feet that allows them to stick to surfaces.

google it..type in scientific insect names. That always helps. OR type in the name of the insect, and all sorts of stuff should pop up

The calcium hydroxide is most likely used to maintain an optimum pH in the solution that contains the poison.  The concentration of the base in these solutions is probably far too low to actually harm the hard outer shell of an insect.  Therfore, I doubt highly that it is used to actually kill the insects (considering the active ingredients in most pesticides are neurotoxins).  A clue would be to look on the pesticide container at the active ingredients.  This list should tell you what is actually doing the killing.
