Many of the already patented traps are either difficult to carry under field conditions or damage the crops inflorescence because of high vacuum pressure and even suck the seed cotton from the opened bolls of the cotton plants. Based on the behavioral characteristics of Bemisia spp., we have designed a shoulder mounted, portable and adjustable trap to disturb whiteflies resting on the underside of the plant canopy and suck it. The whitefly trap catches reflect seasonal activity, seasonal populations in field plots under different treatment regimes. The preferred embodiment of the trap is a simple three-element device which can be easily and inexpensively manufactured by well-known plastic molding techniques. A power operated, shoulder mounted, adjustable and portable whitefly adult suction trap I consist of three components i.e. power source, an impeller and a vacuum tank. The power device of the air flowing type suction trap comprises a power device based on engine/battery/solar connected with an impeller. The impeller is connected with the vacuum tank in the centre and an air blowing pipe (outlet pipe) at lower side. The vacuum tank is fixed with two suction pipes (inlet pipe) attached to its upper side. Inside the vacuum tank two dry air filters are fixed to collect the sucked whiteflies. An aluminum sheet is fixed at the upper side of the trap, which is painted yellow and smeared with grease to trap the whiteflies flying high away from the vacuum are.
