Introduction

• Why insects
• Most diverse group of organisms
• Contribute to vital functions of ecosystem
• Which habitats to conserve?
• Ones with greatest diversity

3

• What method should be used?
• Comparing all orders of insects
• Possibly time consuming needs stats
• Comparing one order of insects
• Generalise answers for all other orders

4
Methods and Materials

• Sample Site
• Combretum park
• Individual sites
• Each site was sampled using three methods
• Sweeping, hitting, active hunting
• Data analysis
• Shannon-weaver
• IndVal

IndVal

• No true indicators for all orders
• 3 IndVal scores of 50 (detectors)
• Hymenoptera Formicidae (Sandstone Ridge)
• Mantodea Thespidae (sandstone Ridge)
• Hemiptera Alydidae (Felsite Ridge)
• No Diptera Indicators or Detectors

Conclusion

• In order to make a good decision about which
  habitats to sample all possible orders of insect
  need to be taken into account
