Agricultural Entomology MCQ Question and Answer | Agriculture MCQ Question

Specific strain of species adapted to a particular set of the environment is called an Ecotype.
An ecotype is a variant in which the phenotypic differences are too few or too subtle to warrant being classified as a subspecies. These different variants can occur in the same geographic region where distinct habitats such as meadow, forests, swamps, and dunes provide ecological niches.
An ecotype is different than a subspecies, which may exist across several different habitats. In animals, ecotypes owe their differing characteristics to the effects of a very local environment.

The microorganism which helps in degradation of fenitrothion is Bacillus subtilis.
Fenitrothion is a phosphorothioate insecticide that is inexpensive and widely used worldwide.
The soil bacteria Bacillus subtilis, converted more than half of radiolabelled 32P fenitrothion to the amino analogue under aerobic conditions at 37°C in 24 hours.
Fenitrothion is gradually inactivated by other bacterial species including gram-positive and gram-negative rods, but not by fungi and yeasts.
