Abstract

A method and an apparatus to collect the samples of the mosquito eggs and larvae with the option to automatically destroy the samples.

Description

Method and apparatus for the automatic collection of mosquito eggs and larvae
Description
Background of the Invention
Mosquitoes are a threat to humans as they transmit the cause for malaria or dengue fever in certain areas of the world.
Both diseases could be fatal for humans.
There are certain methods in use to avoid mosquito breeding. There are also certain methods in use to spread different chemical agents to kill mosquitoes in their different life stages.
Both methods have their limits. Mosquito breeding cannot be always avoided. Toxic agents reach their limits in areas densely populated by humans.
There are some methods around which trap the mosquito itself. Some of those methods emit substances to emulate the smell of humans. Some other methods emit light with a special spectral composition to attract mosquitoes.
This invention intends to interrupt the life cycle of mosquitoes by making the mosquito lays its eggs into the apparatus.
A mosquito will not search for better breeding spots after it found one breeding spot. The eggs can then be collected or destroyed.
The interruption in the life cycle of the mosquitoes will not affect the current population at all. It will only reduce the following generation.
As the mosquitoes follow a very simple life cycle, it is possible with this method to remove mosquitoes from homes of humans if no other breeding spots are in close proximity.
The automated process of filling and emptying the container used as a breeding spot for the mosquito overcomes the main problems of manual sampling. It is not possible to take samples from many different places at the same time to make the samples comparable. It is also not always possible to collect samples without accidentally breeding mosquitoes if the interval time becomes too long.
The use of rain water improves the chance to attract a mosquito to actually lay eggs.
Alternatively, water from a tank populated with natural enemies of the mosquito egg or larva can be used to refill the container emulating the breeding spot.
The preparation of the breeding container is crucial. It should reflect as much as possible the natural breeding environment of the mosquitoes of the area where the apparatus is applied. Ideally, plants or parts of the plant should be inside the breeding container. As water will stick to the plant when the container is emptied, it is better to remove them regularly. The removal process can be automated. The removed plant parts have to be placed into the container for the samples as eggs or larvae could be attached to them.
The apparatus is to be applied as close as possible to the human population to stop the mosquito to search for other breeding spots. The apparatus can be applied directly in the home of humans. The apparatus can be applied directly outside of the human's home.
Applying the apparatus outside the homes has the additional advantage that hiding it inside the natural environment like grass, bushes and trees will stop the mosquito to breed in small water patches very often found in the natural environment.
As no other agent is used which is not present in the natural environment, no side effects on humans are expected.
As no other agent is used which is not present in the natural environment, the mosquito cannot distinguish the artificial breeding spot from the natural breeding spot. v
As no other agent is used which is not present in the natural environment, no resistance can be developed by the mosquito.
As a very basic element of a mosquito's life is used to trap future generations, it is highly unlikely that a simple life form as a mosquito will understand the concept.
A water pipe can be used as an alternate water source.
Summary of the Invention
The present invention provides a method and an apparatus to collect mosquito eggs and larvae. It can also be used to destroy the eggs or larvae.
The apparatus simulates an ideal breeding spot for the mosquito. This will make the mosquito lay its eggs into the apparatus. The apparatus will move the eggs in regular time intervals into separate containers.
The samples can then be collected from all apparatus to be examined in a laboratory to find details of the mosquito population in an area.
The apparatus then refills the breeding area with fresh water from a container.
Alternatively, the eggs are not collected but destroyed. This can be used to control a mosquito population.
Alternatively, the water tank and the disposal unit can be combined into one unit. The combined device must then contain natural enemies of the mosquitoes or its larvae to make sure no mosquito breeding will take place and also water supplied into the breeding container will be free of larvae.
Alternatively, the control unit can be replaced by a switch to manually trigger the water exchange.
Detailed Description of the preferred Embodiments
Fig. 1 shows the overview of the apparatus to collect the eggs of mosquitoes.
A container 1 contains a certain amount of water. The container 1 is connected via a pipe 2 with a flow control unit 3. The flow control unit 3 is connected via a pipe 4 with a water tank 5. The water tank 5 contains fresh water to be used to refill container 1.
The flow control unit 3 is connected via a control line 21 with a control unit 20.
The container 1 is connected via pipe 10 with a flow control unit 11.
The flow control unit 11 is connected via a control line '22 with the control unit 20.
The flow control unit 11 is connected via a pipe 12 with a disposal unit 100. The disposal unit 100 destroys the collected eggs. The disposal unit 100 can be any thing from a simple drain to an oven to burn the eggs.
The flow control unit 11 is connected via a pipe 13 with a collection unit 101. The collection unit 101 collects all samples in separated sections.
The container 1 is covered by a roof 200 to block rain and other unwanted liquids or solids from falling into container 1.
An optional net 201 can be used to protect container 1 from pollution with larger objects while still leaving the mosquitoes inside.
The control unit 20 is connected via a line 31 with a day/night sensor 30.
Operation
The control unit 20 closes flow control unit 11.
The control unit 20 then opens flow control unit 3 to let water from tank 5 flow into the container 1. The amount of water is set so that even of the system fails completely the container 1 will be dry before any larvae might developed in container 1.
The apparatus will stay in this status now for a certain time to give mosquitoes a chance to lay their eggs into the container 1.
The control unit 20 will open flow control unit 11 at a given time. This will be determined by different data. It is recommended to open flow control unit 11 only during a period of time when a low activity by mosquitoes are expected.
If the apparatus is in disposal mode, flow control unit 11 will then lead the water via pipe 12 to the disposal unit 100. The eggs will then be destroyed by the disposal unit 100.
If the apparatus is in collection mode, flow control unit 11 will then lead the water via pipe 13 to the collection unit 101.
The control unit 11 then waits for a preset time to make sure that any eggs still left in container 1 will dry out.
The cycle restarts here with the refilling of container 1.
The control unit 20 can be equipped with a day/sensor 30. The day/night sensor is connected via connection 31 with the control unit 11.
The control unit 11 can use the signal from the day/night sensor 30 to trigger off the exchange of the water in container 1 when the lowest mosquito activity is expected. A very low mosquito activity is expected around noon.
The invention has now been described, with reference to the preferred embodiments. Alternatives and substitutions will now be apparent to persons of skill in the art.
