Comments on the article
With the onset of summer, mosquitoes become a real disaster for people living in rural areas, and for townspeople - summer residents. All kinds of ultrasonic repellers, repeatedly advertised, are extremely ineffective. Various "Raptors" and "Fumitoks" emit poisonous odors, which may not be safe for humans either. Some radio amateurs (L.1) go so far as to install devices that kill mosquitoes with high voltage.
In this regard, I want to share a proven and safe way to deal with these "creatures".
The fact is that mosquitoes, like any other nocturnal insects, have a habit of flying into the light. Therefore, for some time they can be lured to some kind of lamp, but not destroyed by an electric charge (as in L.1), but sucked into a gauze bag using an electric fan, such as is installed on computer power supplies. The air flow created by the fan, together with the light, makes it so that mosquitoes do not have time to enter the room if this device is hung in front of the open window of the room.
There are several advantages of this method: firstly, there is no poisonous chemistry, secondly, there is no ultrasound, which acts not so much on mosquitoes as on humans (the head starts to hurt, I know from my own experience), thirdly, there is no high voltage, and fourthly, the design is extremely simple. There is also a drawback - the fan hisses quietly.
A schematic representation of such a mosquito trap is shown in Fig. one.
Fig. 1
The role of the bait is performed by a small-sized light bulb (from the refrigerator), the cartridge of which is tied to a wire handle, made of steel wire, bent so that a loop for suspension is obtained at the top. A cardboard two-liter tetrapack from juice is used as a case. Its upper end is cut off, and two holes are pierced in the sidewalls, through which a wire handle is attached. A hole is cut in the bottom of the package for the instrument electric fan. The fan is positioned so that it pulls air down from the lamp. At the bottom, with the help of a hair band, a gauze bag is attached.
The whole structure is suspended in the corner of the window opening. Mosquitoes attracted by the light approach the lamp. And under the action of the air flow, they are first drawn into a cardboard case, and then, by a fan, they are driven into a gauze bag, where they remain.
Periodically (about once a week) you need to clean the fan blades from insects adhering to them.
Instead of a tetra pack, you can use any other suitable cardboard box, or glue it from cardboard.

Machine for thinning flowers in gardens
02.05.2024
In modern agriculture, technological progress is developing aimed at increasing the efficiency of plant care processes. The innovative Florix flower thinning machine was presented in Italy, designed to optimize the harvesting stage. This tool is equipped with mobile arms, allowing it to be easily adapted to the needs of the garden. The operator can adjust the speed of the thin wires by controlling them from the tractor cab using a joystick. This approach significantly increases the efficiency of the flower thinning process, providing the possibility of individual adjustment to the specific conditions of the garden, as well as the variety and type of fruit grown in it. After testing the Florix machine for two years on various types of fruit, the results were very encouraging. Farmers such as Filiberto Montanari, who has used a Florix machine for several years, have reported a significant reduction in the time and labor required to thin flowers.

Advanced Infrared Microscope
02.05.2024
Microscopes play an important role in scientific research, allowing scientists to delve into structures and processes invisible to the eye. However, various microscopy methods have their limitations, and among them was the limitation of resolution when using the infrared range. But the latest achievements of Japanese researchers from the University of Tokyo open up new prospects for studying the microworld. Scientists from the University of Tokyo have unveiled a new microscope that will revolutionize the capabilities of infrared microscopy. This advanced instrument allows you to see the internal structures of living bacteria with amazing clarity on the nanometer scale. Typically, mid-infrared microscopes are limited by low resolution, but the latest development from Japanese researchers overcomes these limitations. According to scientists, the developed microscope allows creating images with a resolution of up to 120 nanometers, which is 30 times higher than the resolution of traditional microscopes. ... >>
Air trap for insects
01.05.2024
Agriculture is one of the key sectors of the economy, and pest control is an integral part of this process. A team of scientists from the Indian Council of Agricultural Research-Central Potato Research Institute (ICAR-CPRI), Shimla, has come up with an innovative solution to this problem - a wind-powered insect air trap. This device addresses the shortcomings of traditional pest control methods by providing real-time insect population data. The trap is powered entirely by wind energy, making it an environmentally friendly solution that requires no power. Its unique design allows monitoring of both harmful and beneficial insects, providing a complete overview of the population in any agricultural area. “By assessing target pests at the right time, we can take necessary measures to control both pests and diseases,” says Kapil ... >>
| Random news from the Archive microplastics in table salt
21.10.2018
Korean scientists, together with Greenpeace activists, studied more than 30 brands of table salt produced in different countries of the world. In 90% of the samples, they found particles of microplastics.
The largest amount of microplastics was found in salt produced in Asia. For example, one salt sample from Indonesia contained more than 13 microplastic particles. Microplastics are pieces of plastic less than 000 millimeters in size.
“Research has shown that microplastics are found in seafood, wildlife, tap water, and now salt. This crisis was expected as microplastics continue to enter our oceans. We need to eliminate the very cause of plastic pollution. It is necessary for human health and the environment to so that corporations will immediately begin to reduce the use of single-use plastic," said Mikeng Kim, Greenpeace East Asia spokesman.
