| Diagnostic Technique |
Role of Viruses in Diagnosis |
| ELISA |
Enzyme-Linked Immunosorbent Assay detects viral antigens or antibodies in patient samples. |
| PCR |
Polymerase Chain Reaction amplifies viral genetic material for accurate and rapid detection. |
| Viral Load Monitoring |
Measures the amount of virus in the patient’s blood for disease progression monitoring. |
| Viral Culture |
Grows viruses from patient samples to identify the specific virus. |
| Serological Tests |
Detects viral antibodies in the blood to assess previous infections or immunity. |
| Genomic Sequencing |
Characterizes viral strains, tracks mutations and informs vaccine development. |
| Immunofluorescence Assay |
Uses fluorescent-labeled antibodies to detect viral antigens in patient samples. |

Role of viruses as a biopesticides
| Aspect |
Detail |
| Introduction to Biopesticides |
· These are naturally occurring substances derived from living organisms, including viruses. These are used for pest management. |
| Significance of using virus as biopesticides
|
· Many biopesticide viruses exhibit high host specificity, targeting only specific pest species.
· Viruses used as biopesticides specifically target and infect pest organisms.
· Biopesticide viruses infect and replicate within the pest, leading to disease and their mortality.
· Biopesticides are generally environment friendly. These are biodegradable and have offer low toxicity to non-target species.
· The use of biopesticides reduces the accumulation of chemical residues in the environment and agricultural products.
· Viruses used as biopesticides are part of sustainable agriculture practices. It has reduces the dependence on synthetic chemical pesticides.
· Some biopesticide viruses create persistent infections in the target pest population thus helps to provide long-term control. |
| Possible role in integrated pest management |
· Virus used as biopesticides can be part of integrated pest management (IPM) strategies.
· It will help to reduce the development of pest resistance to chemical pesticides. |
