11. Study of Animal Type - Cockroach - part 08 - Interactions with mankind


Interactions with mankind :

  • Cockroach causes damage to the household materials like clothes, shoes, paper etc. 
  • They also eat and destroy the food stuff.
  • They contaminate food which gives typical smell and make it unpalatable.
  • As they live in sewage pipes and gutter holes, they carry with them harmful pathogens causing diseases like cholera, diarrhoea, tuberculosis, typhoid, etc.
  • Cockroach serves as a part of food chain also. 
  • Many amphibians, birds, lizards and rodents prey upon them making them a part of food chain. 
  • They are eaten by certain groups of people in South America, China and Myanmar.
  • Cockroach is used as experimental animal in laboratories and for biological research, as they can be obtained easily without causing damage to ecological balance.

Control Measures : 

  • As cockroach is economically harmful organism it must be controlled in an efficient way. 
  • Some of the measures are as follows :

1. Good Sanitation : 

  • Dark and humid places of kitchen, cupboards, trolleys must be cleaned regularly. 
  • Cracks and crevices and such areas must be filled. 
  • There should not be any place in a home, where accumulation of garbage may take place.
  • Cockroaches frequently enter home by migrating up from sewer connections if the drain trap is dry. 
  • So always keep the drain trap filled with water.
2. Chemical control : 

  • Organophosphates, carbamates, pyrethroids and boric acid are efficient poisons of cockroaches, various types of their formulations are available in market,  under various brand names.
  • Cockroaches are considered as bioindicators! Their presence indicate unhygienic conditions

  6. Biomolecules - part 01 - Carbohydrates Introduction : Our planet is having a wide diversity of living organisms that are classified as - unicellular  (consisting of a single cell; including bacteria and yeast) or  multicellular  having many cells (e.g. plants and animals).  living organisms have cell as the basic structural and functional unit.  The cells have protoplasm containing numerous chemical molecules, the biomolecules. Biochemistry  : Biochemistry is  biological chemistry  that provides us the idea of the chemistry of living organisms and molecular basis for changes taking place in plants, animals and microbial cells.  It develops the foundation or understanding  all biological processes  and communication within and between cells as well as chemical basis of inheritance and diseases in animals and plants. Chemical analysis of all living organisms indicates presence of the most common elements like  carbon, h...

  6. Biomolecules - part 02 - Lipids B. Lipids : These are group of substances with greasy consistency with  long hydrocarbon chain containing carbon, hydrogen and oxygen. In lipids, hydrogen to oxygen ratio is  greater than 2:1  (in carbohydrates it is always 2:1). Lipid is a broader term used for fatty acids and their derivatives.  They are soluble in organic solvents (non-polar solvents).  Fatty acids are organic acids which are composed of hydrocarbon chain  ending in carboxyl group (-COOH).  They can be  saturated fatty acids  with no double bonds between the carbon atoms of the hydrocarbon chain.  Palmitic and stearic acids  found in all animal and plant fats are examples of saturated fatty acids. Unsaturated Fatty Acids  are with one or more double bonds between the carbon atoms of the hydrocarbon chain.  Oleic acid  found in nearly all fats and  linoleic acid  found in many seed oils are example...

6. Biomolecules - part 05 - Enzymes

  6. Biomolecules - part 05 - Enzymes Enzymes : Thousands of different chemical reactions take place automatically at a given time in a tiny living cell. The reactions take place at the body temperature.  If these enzymes were not present in the cell, either the reactions would not occur or if they occur they would occur at a  very very slow rate . Know the scientists : German chemist  Edward Buchner  discovered enzymes by accident.  Buchner discovered that living cells were not necessary but that  yeast  extract could bring about fermentation.  He then coined the term Enzyme (Gk. En = in, zyma = yeast i.e. in yeast). This term is now commonly used for all biocatalysts. Each enzyme catalyzes a small number of reactions, specifically perhaps only one. Substrate :  The substance upon which an enzyme acts is termed as the substrate.  Endo-enzymes :  The enzymes which act within the cell in which they are synthesizedare known as en...
