The aerial insect trap is used for quantitative and qualitative estimation of the flying insects in the field. It is comprised of an entrapment held horizontally over an upright, which provides free rotation to the entrapment and orient the opening of the entrapment against the wind direction. The entrapment is a barrel shaped body with both of its ends open. One of the ends is fixed with a hollow truncated cone which nests inside of the body of the barrel while other end of the barrel opens into a board sleeve, which is kept tied from the other end thus forming a sac like structure. The narrow opening of the cone remains free in the core of the barrel. The sleeve is permeable to air. The wind enters through the truncated cone and pass through the sac. The insects by their own flight and the small insects with the gush of the wind enter the cone and get trapped in the cavity of the barrel and sleeve. The trapped insects find it difficult to escape. The trapped insects are removed by untying the sleeve as and when required. The trap is mounted on an upright with a telescopic arrangement for adjusting the height of the entrapment. The trap catches the flying insects and the insect collection represent the unbiased natural population of the area when it is used since it contains no lure in it.
