For instance, attractants are pheromones which bind the members of a colony of social insects. Overpopulation refers to a population which exceeds its sustainable size within a particular environment or habitat. A cohort life table tracks organisms through the stages of life, while a static life table shows the distribution of life stages among the population at a single point in time. Make your text as brief as possible to maintain a larger font size. Insect relationships have always been very difficult to unravel because of the sheer diversity of insect life - one in every two multicellular organisms (animals and plants) on Earth is an insect. Population dynamics – role of biotic factors – competition – parasitoids and predatots. This phenomenon was first reported in Union of Soviet
Socialist Republics (USSR). Clay-Humus-Microbe Interaction: Clay mineral (and humic substances) affects the activity, ecology and population of microorganisms in soil.

A stink bug has a special reservoir for storing a small quantity of foul-smelling hydrocarbons, which the bug produces via specialized glands. For example, parasites use the host smell for searching and preys use predators’ smell to escape away. Entomology.
