Description
AN IMPROVED DELTA TRAP FOR INSECTS
TECHNICAL FIELD
[0001] Embodiments of this invention are generally related to the field of entomology. Embodiments are also related to pest control. Embodiments are further related to pest control using pheromone traps.
BACKGROUND OF THE INVENTION
[0002] There are basically three kinds of insect attraction traps; light traps, pheromone traps and colored sticky traps. Prior art is replete with various modifications of the three basic traps to target different insect groups based on various parameters like the source of attraction of the target pest, design attributes of the trap, size of the pest and the surroundings for the site of infestation etc.
[0003] Delta traps are triangular cross sectional traps with contiguous borders and are ideally sticky traps with a pheromone- based attractant in a dispenser kept inside to lure the insects. These traps are ideal for small to medium sized flying insects, where the adult males ( moths,fruitflies) get attracted to the lure and get entangled on to the sticky internal surface.
[0004] The delta traps in prior art have two openings (triangular cross sectional) one at each end through which the insects get inside the trap towards the lure and get entangled in the surrounding adhesive surface. The present invention improves the efficiency of the moth/fruit fly catch in delta trap mainly by opening additional access windows in the design of the trap.
SUMMARY OF THE INVENTION
[0005] The following summary is provided to facilitate an understanding of some of the innovative features unique to the disclosed embodiment and is not intended to be a full description. A full appreciation of the various aspects of the embodiments disclosed herein can be gained by taking the entire specification, claims, drawings, and abstract as a whole.
[0006] Therefore, one aspect of the disclosed embodiment is to provide an improved delta trap by opening additional access windows for the insects in the design.
[0007] Another aspect of the disclosed embodiment is to provide improved insect catch by increasing/ the sticky catch area.
[0008] Another aspect of the disclosed embodiment is to provide an improved insect trap by giving the trap a yellow color, which is known to attract pest insect groups including moths and fruitflies, while not so attractive to the beneficial insects like bees.
[0009] The aforementioned aspects and other objectives and advantages can now be achieved as described herein. The improved delta trap disclosed here in is designed by additional access windows of circular shape along each of the slant surfaces of the trap. It is known to entomologists and those interested in the art that insects like moths, fruit flies etc tend to respond more when the attractant odour plumes come out from additional directions than limited to the two large entry points. The improved delta trap disclosed herein, is designed to utilize this insect behavior to trap more insects and thus improve the efficiency of the trap.
[0010] The improved delta trap also has larger replaceable sticky surface along the inner surface of the triangular trap, thus increasing the overall catch of the trap. The colour of the delta trap is another novel embodiment of the invention, where yellow is chosen strategically to visually attract the target insect groups, although the main attraction source is olfactory from the synthetic sex attractant
lure. It is known in art that yellow colour of trap can visually attract several insect pest groups including moths and fruitflies. The device proposed herein is an exemplary demonstration of working of the proposed concept of an improved delta trap in a cost effective way. The economic importance of insect groups targeted and operating protocol of the basic model can be standardized and adapted by a person skilled in the art to achieve the same or enhanced performance. The proposed invention achieves at least 50% of more insect catches when compared to the available delta or other alternative insect traps in the market. The major target insects are moths whose larval (caterpillar) stages infest rice and other food crops, vegetable and fruit crops, besides cotton and sugarcane, and also fruit flies infesting fruit and vegetable crops.
