This document discusses using insects as biosensors for environmental pollution monitoring. It introduces insects as good biosensors due to their abundance and susceptibility to environmental changes. It then lists various insect groups like dragonflies, aphids, wasps, and bees that have been used as biosensors for pollution monitoring. The document outlines the materials and methods for using insects as indicators of pollution, which includes selecting sensor insects based on suitability and establishing relationships between disturbances and insect responses. It provides examples of how different insect species have been used to monitor pollutants like metals, pesticides, and climate change factors. The conclusion is that insects make excellent biosensors for environmental monitoring due to their diversity, sensitivity to changes, and response to disturbances.

3. INTRODUCTION
• Pollution is the great threat to environment
• Different biosensors are now used for the environmental Monitoring
• Insects are used as biosensor due to their abundance in nature and highly susceptible to the
environmental changes
BIO-INDICATOR GROUPS OF INSECTS
1. Dragonflies
2. Aphids
3. wasps
4. Stoneflies
5. Honey bees Beetles
6. Collembolans
7. Butterflies
8. Ants

4. REVIEW OF LITERATURE
• Insects as Biosensors have been generating great interest in environmental pollution research.
• Many publications on environmental degradation based on the insect as pollution sensor
• Insect as biosensor are the important aspect in the monitoring of terrestrial ecosystem
• Great size of Information regarding their use in different types of monitoring is currently
available

7. RESULTS AND DISCUSSION
• Ants have been used to measure pollutant concentrations in borealis forests and Australia
• Bees are used to monitor trace metals radioactivity after the Chernobyl disaster, pesticides and
herbicides effects, industrial wastes and pollutants
• Wasps seem to be a promising species for pollution by lead biomonitoring
• Aphids show an increase in their population density in high CO2 concentrations which can be
use in climate change studies

8. CONCLUSION
• The use of biosensors is essential for environmental monitoring.
• The main characteristics of a biosensor are: specie richness ecological faithfulness, fragility to
small environmental changes and good organism responses
• Class Insecta has all of these characteristics
• Therefore, Class Insecta has many potential representatives that can be used as environmental
biosensors
