1. Presentation on:- Method of Insect Collection

2. Methods of collection Insects belong to various habitats. Can be collected by different methods. These methods are mentioned below: Hand Picking Sweeping Beating Aerial Netting Trapping Aspirator Berlese funnel

3. Hand Picking The soft bodied insects are collected. Forceps or hand brush is used to handle insects, to avoid damaging insect body. E.g.: Ants, Larvae, termites etc.

4. sweeping Sweeping nets are used for collection from herbage. It must be of tough cloth. E.g.: Insects in flowers, bushes or near groung .

7. Trapping Traps are an easy & often effective method of collection. The attractive material is used to attract insects & are trapped. The trap depends on the type of insects one wants to collect. Some common traps are enlisted below: LIGHT TRAP BAIT TRAP WIND TRAP

8. Trapping Ligt Trap An artificial light source is used as attracting material. Electrical lamp is placed adjacent to white muslin cloth in field.
