When a solid object is suspended in a beaker filled with water placed on a weighing machine, the reading increases and but the object is suspended in a beaker filled with air, the reading does not increase. What is the reason behind this.

First of all, the duplicate mentioned in comments is not duplicate at all.
The scale does not change because I assume you are doing the weighing in open atmosphere where everything including your beaker, ball, even scale are already immersed in air. The open spaces are already fully filled with air. The atmospheric pressure being everywhere, the bernoulli's principle is not applicable, or in other words, it applies to everything involved and cancels out.
So, your observation is correct and reasonable - in case you the weighing is taking place in open air.
