Question

Detection and diagnosis of insect pest and diseases

Answer 1

 researchers use modern and innovative approaches for the early detection of plant pathogens and insects, allowing growers to manage the spread of disease and pests and minimising the need for traditional chemical controls. Detection methods include:

Virus testing

Plant disease diagnostic technology including DNA and ELISA assays

Molecular biology to identify new species and new strains

Host range testing for pest risk assessment.

Geographic Information Systems (GIS) and other mapping tools are also used to model insect distribution, dispersal and spread.

Answer 2

Some of the diseases caused by insects or microbes and their detection are as follows -

1. Typhoid - This disease is caused by a bacteria. The name of that bacteria is Salmonella typhi. This disease can detected by a test known as Widal Test.

2. Malaria - This disease happens through the bite of a mosquito which is. female. Female mosquitoes carries a protozoa named Plasmodium which causes malaria.
