Sporeine is primarily a

  1. Herbicide

  2. Pesticide

  3. Insecticide

  4. Mycoherbicide
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation
Sporeine is a bioinsecticide derived from Bacillus thuringiensis. It is used to suppress the population of many coleoptereious and lepidopterous larvae in Russia, USA and many European countries. It is the trade name given to the commercial product made from Bacillus thuringiensis (Bt). The active ingredient in Bt is a toxic protein, that actually binds to specific sites on the midgut. It is mainly used as an insecticide in agriculture. 
Thus, the correct answer is option C.

Which of the following institutes organises the training programs on various aspects of plant protection with an emphasis on integrated pests management?

  1. National botanical research institute

  2. Nation plant protection training institute

  3. National Institute of biomedical genomics

  4. None of the above
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation
The National Plant Protection Training Institute (NPPTI) was established in 1966 for Human Resource Development in Plant Protection Technology under the Directorate of Plant Protection, to create qualified pest management personnel. It organises the training programs on various aspects of plant protection with an emphasis on integrated pests management. Consequently, the Institute has been registered as an Autonomous Society under the Ministry of Agriculture, Govt. of India,
So, the correct answer is option B.

Economic threshold injury indicates

  1. Pest density

  2. Pest management

  3. Pest control

  4. None of the above
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation
Economic threshold injury is a concept of integrated pest management which denotes the pest density at which management action should be taken to prevent an increasing pest population from reaching the economic injury level.
So, the correct answer is option A.

Biological control of pests is 

  1. Polluting

  2. Highly expensive

  3. Self perpetuating

  4. Toxic
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

The biological method is the technique in which there is the use of living microorganisms or its product for the control of pests. This method uses the microbes which act as predators or enemies of the target pest species. The biological control method is often relatively inexpensive because the method uses the microorganisms which can be easily cultured. These are beneficial microorganisms which are used, so they do not contribute the pollution. If biocontrol agents are introduced in any area, survive for multiple years and become self-perpetuating. They will spread over a large area over time and continue to exist for a very longer period. 

Thus, the correct answer is option C.

Latest trend in plant disease control is

  1. Chemical control

  2. Biological control

  3. Good manure and fertilizer

  4. Breeding for disease resistance
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Integrated pest management (IPM) is the programme which particularly focuses on agricultural crop diseases and its management. According to It, the use of biological control agent or other living organisms can control the plant diseases. Biological control is environment-friendly and effective against a broad range of insect pests and relatively easy to adopt.

So, the correct answer is 'Biological control'

Which of the following process aims at suppressing the pests below economic injury level?

  1. Integrated pests management

  2. Integrated pollution prevention and control

  3. British Pest Control Association (BPCA)

  4. None of the above
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation
Integrated pest management is a broad-based approach that integrates practices for economic control of pests. It aims to suppress pest populations below the economic injury level. The process starts with monitoring, which includes inspection and identification, followed by the establishment of economic injury levels. The economic injury levels set the economic threshold level.
So, the correct answer is option A.

Concentration of insecticide in the animals of a species is known as

  1. Eutrophication

  2. Bioconcentration

  3. Bioindicator

  4. None of the above
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Bioconcentration is the process of ingestion and retention of the chemical substance in an organism. It mainly occurs in the aquatic organism by the exposure of waterborne chemicals.

When a natural predator living being applied on the other pathogenic organisms to control them, this process is called as

  1. Biological control

  2. Genetic engineering

  3. Confusion technique

  4. Artificial control
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Biological control is a component of an integrated pest management strategy. Biological control is keeping the population of an organism or harmful pests and weeds under check by means of natural predators, parasites and amensals.
