 In this module, we will discuss different collection methods There are many methods by which we can collect animals For example, black light trap, sweep net, suction device, d-wag method, pitfall method, aspirator method, beating sheet method, trawling method, deeper method and hand picking method Now, we will discuss all these methods one by one First of all, black light trap method This method is called black light trap method These entomologists usually use it to collect night flying insects In this method, a black light is suspended in front of white sheet And this white sheet has an ultraviolet light hanging on it Insects attract to this light and researchers can easily collect insects If we look at this slide, the first slide, the first photo, A rope is tied between two trees The second picture has a white sheet hanging on it And a light is hanging on it While the third picture has a white sheet hanging on it Because light is attracted to it, the researcher can easily catch the insects Similarly, the second method is sweep net Sweep net is used to collect long grass insects Especially dispersed insects This method is called sweep net This is a canvas bag with round mouth and long rod This is a very effective and easy method for collecting insects In entomology, the use of these traps is very high And this is a very popular method for collecting insects Similarly, if we look at this picture, A suction device is shown here Because it is a d-wag If we want more collection, we want to work on a larger level So for that, this is an engine operated device Which is called a d-wag Because of this, we can easily collect thick vegetation, long grasses, Orchards from there Because in this picture, you can see that this is an engine operated device Which can be operated with gasoline With this pressure, insects move towards themselves Later, we can easily separate these insects And in this, all the unwanted insects Or the extra material or the dust We can easily separate them from this collection
