Microorganisms (viruses, bacteria and fungi) or their bioactive agents can be used as active substances and therefore are referred as Microbial Pest Control Agents (MPCA). Baculoviruses are the only viruses being used as the safest biological control agents. They infect insects and have narrow host ranges.
What is the best known microbial insect pathogen?
Bacillus thuringiensis
1. Bacillus thuringiensis. Bacillus thuringiensis (Bt) is the most studied entomopathogenic species and some of its crystal producing strains have certainly represented the main active substances used for the microbial pest management during the last decades [7].
What are the methods of controlling insect pests?
Control methods
- Biological pest control.
- Cultural control.
- Trap cropping.
- Pesticides.
- Hunting.
- Physical pest control.
- Poisoned bait.
- Fumigation.
Why are microorganisms used in biotechnology?
Due to their diverse metabolic potentials and established manipulation techniques, microbes are considered to be excellent materials for biotechnology. Pure cultures of microbes are exploited in industrial processes to produce alcohols, organic acids, and polymeric materials (2).
Which are the pathogenic microorganisms?
Pathogenic microorganism may be viruses, bacteria, mycobacteria, fungi, protozoa and so on and infects people or animals in direct or indirect ways. Virus often results in serious diseases. Recent years, human have been challenged by several diseases caused by virus, such as SARS, Ebola virus, hepatitis B, HIV etc.
What is insect pest?
Insect pests are insects that affect crop growth stages by damaging (chewing, biting, sucking or boring) various plant parts such as leaves, flowers, fruits, stems and roots.
Why are microorganisms found everywhere?
Microbes grow and reproduce in habitats where no other organisms can survive. Microbes also are found in more mundane places, such as on our hands, in the air and in soil. This activity is designed to help students understand the diversity of microorganisms present in our immediate surroundings and on our bodies.
What are microorganisms examples?
A microorganism is a living thing that is too small to be seen with the naked eye. Examples of microorganisms include bacteria, archaea, algae, protozoa, and microscopic animals such as the dust mite. Microorganisms live in water, in soil, and on the skin and in the digestive tracts of animals.
What are the 3 types of controls for pests?
As mentioned above, there are many pest control methods available to choose from, but they can be loosely grouped into six categories: Hygienic, Biological, Chemical, Physical, Fumigation, Fogging and Heat treatment.
What is the most popular method of controlling insect pest?
Pesticides
Pesticides. Pesticides are the most common pest control method which can be done by anyone.
What is a microbial pest control agent?
Microorganisms (viruses, bacteria and fungi) or their bioactive agents can be used as active substances and therefore are referred as Microbial Pest Control Agents (MPCA). They are used as alternative strategies to chemical insecticides to counteract the development of resistances and to reduce adverse effects on both environment and human health.
What are the benefits of using bacteria in bio-insecticides?
Bacteria are the ideal tools for developing ‘smart’ precision bio-insecticides and preventing disease transmission by insects. Despite the current US President’s denials, there is incontrovertible evidence that human activity has negatively impacted our environment.
How do smart pest control measures affect other flora and fauna?
Smart measures to control pest insect populations should have little or no impact on the other flora and fauna. For example, an understanding for how bacterial symbionts can impact the biology of their insect hosts has led to a control strategy that limits the transmission of dengue virus.
Are natural entomopathogenic insecticides safer?
These natural entomopathogenic agents, which have specific modes of action, are generally considered safer as compared to conventional chemical insecticides. Baculoviruses are the only viruses being used as the safest biological control agents. They infect insects and have narrow host ranges.
