Excellent biocontrol agents to treat ecologically sensitive areas
1 Nucleopolyhedrovirus
2 Trichoderma
3 Bacillus thuringiensis
4 Azospirillum
Explanation:
The genus Nucleopolyhedrovirus provides viruses that are being used for species-specific narrow spectrum insecticidal application they have been shown to have no negative impact on plants, birds, animals, fish and even non-target insects.

One of the major difficulties in the biological control of insect pest is that
1 The method is less effective as compared with the use of insecticides
2 The practical difficulty of introducing the predator to specific areas
3 The predator develops a preference to other diets and may itself become a pest
4 The predator does not always survive when transferred to a new environment
Explanation:

Which of the following is not used as a biopesticide ?
1 Xanthomonas campestris
2 Bacillus thringiensis
3 Trichoderma harzianum
4 Nuclear Polyhedral Virus (NPV)
Explanation:
Xanthomonas campestris is a Gram negative bacterium that causes black rot of crucifer by darkening the vascular tissue. It is not used as a biopesticide. Biopesticides are certain types of pesticides made up of living microorganisms. A biopesticide is a biological susbtance or organism that damage, kills or repels organism seems as pests.

Identify the incorrect statement with reference of Biocontrol agents:
1 They help to increase the use of synthetic pesticides
2 They do not affect non-target pests
3 They do not show any negative impact on crop plants
4 They are significant in treating ecologically sensitive area
Explanation:
Biocontrol agents do not help to increase the use of synthetic pesticides. In fact, they are often used as an alternative to synthetic pesticides because they are more environment friendly.
