, Description:FIELD OF THE INVENTION
[0001] The present invention relates to the field of pest control particularly mosquitoes. Specifically, the present invention relates to a kairomone canister comprising kairomone lures used to control blood sucking insects particularly mosquitoes. The present invention relates to a kairomone canister comprising non-toxic and biodegradable kairomone lures containing active components below the toxic levels of exposure. The present invention further relates to kairomone canister comprising two kairomone lures, wherein first lure is Ethyl vinyl acetate (EVA) biodegradable resin coated with non-toxic proportions of active components and second lure is Carbon dioxide (CO2) generating bio-resin.

BACKGROUND OF THE INVENTION
[0002] Background description includes information that may be useful in understanding the present invention. It is not an admission that any of the information provided herein is prior art or relevant to the presently claimed invention, or that any publication specifically or implicitly referenced is prior art.
[0003] Blood sucking insects rely on biochemical cues such as odors and visual cues to locate and identify hosts on which to feed. However, the detection of olfactory cues that emanate from the bodies and breath of vertebrate hosts dominates during this process. Many of these chemicals used as attractant lure in trapping devices for the blood sucking insects are called kairomones. Many organic acid and alcohol compounds have been reported as mosquito attractants as they emulate lure which mimics the human/ cattle body scent. Some common compounds acting as kairomones include lactic acid, octenol, ammonia etc. Carbon dioxide (CO2) released by human beings is one of the most important olfactory stimuli which mimics host body odor and is involved in orientation toward hosts by mosquitoes and other blood feeding insects.
[0004] Most common odor baits contain carbon dioxide (CO2), which enhances trap catches, given its role as a mosquito flight activator. However, the use of CO2 is expensive and logistically demanding for prolonged area-wide use. The application of this gas from pressurized cylinders, fermenting sugar (i.e., sucrose) or molasses and/or the use of dry ice present major challenges to the use of CO2 based mosquito attractants under field conditions. The gas cylinders are heavy, bulky, expensive and prone to leakages and dry ice can be difficult to obtain, transport and store. While CO2 produced by fermenting refined sugar or molasses can offer a solution to these problems, this method of CO2 production is also expensive and presents logistical challenges when used on a large scale because the gas is only produced over one trapping night (~ ten hours) and must be replenished daily. Another method of CO2 generation in available market products is by using thermal heating of metals to produce high CO2 which mimics the human CO2 exhalation and thus lures blood seeking mosquitoes. A working temperature of 95 to 115 ?F should be achieved for the same. The electric and heat energy is required in high quantities, which is difficult for utilization for everyday needs.
[0005] Usage of CO2 generating devices causes increase in the CO2 concentration in the surrounding air column leading to greenhouse effect and global warming. There is no non-toxic, sustainable CO2 generating alternative for mosquito lure available in market.
[0006] Most of the available attractant lures in market are principally for outdoor purpose and have an unpleasant odor, which cannot be utilized for domestic premises. The major proportions of the available chemicals are repellent in nature, which contain insecticides. Insecticides are chemicals which on continuous exposure causes nervous problems, sinus, nausea, asthma, breathing trouble, eye irritation etc., to humans, children, and pet animals.
[0007] There is, therefore, a need to develop safer, non-toxic, economical and sustainable sources of mosquito lures comprising active components below the toxicity level for humans, that can be used to attract and capture mosquitoes and which can overcome the deficiencies associated with the known arts.

OBJECTS OF THE INVENTION
[0008] An object of the present invention is to provide a safer, non-toxic and economical mosquito attractant kairomone canister.
[0009] Another object of the present invention is to provide a kairomone canister comprising kairomone lures to attract mosquitoes.
[0010] An object of the present invention is to provide kairomone lures which are safe for humans as well as pets and does not contain any unpleasant odor.
[0011] An object of the present invention is to provide kairomone lures that can be utilized for domestic as well as outdoor purposes.
[0012] Another object of the present invention is to provide kairomone lures wherein the amount of active compound is below the toxicity level.
[0013] Yet another object of the present invention is to provide kairomone lures wherein the kairomone lure is released to the surroundings by the contact of air currents.
[0014] Yet another object of the present invention is to provide a kairomone canister which works independent of power supply.
[0015] Still another object of the present invention is to provide kairomone canister that can be incorporated into different type of insect traps.
