Why do moths eat wool?

There is a moth that is known as clothes moth, and most people consider it to be responsible for making holes in our clothes, furs and carpets. But the moth is not at all involved in this damage.

The mole never eats. She lives only to lay her eggs and then die. All the damage is done by her offspring when they are in the caterpillar stage.

Moths lay their eggs in wool, furs, carpets and other items. After about a week, the eggs turn into caterpillars. Caterpillars is the common name for butterfly larvae, moths and sawflies.

The main function of caterpillars is to eat and grow. The caterpillar makes a small tube-shaped sheath of wool on which it feeds. She leaves a web-covered trail and weaves a silk cocoon.

So, you see, the problem with protecting clothes from moths is to make sure that no eggs are laid on them. Before putting away clothes for the summer, they need to be aired and carefully examined so that there are no eggs or larvae on them. A good way is to put it in paper or a tight box: moths do not eat clothes through paper. Tablets repel moths, but do not destroy already laid eggs and caterpillars that may have already appeared.

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 ... >>

New Toshiba Robot Vacuum Cleaners 29.08.2014

In September, the Japanese corporation Toshiba will start selling new robotic vacuum cleaners of the Torneo Robo series, which are characterized by an improved design and enhanced dust and debris collection capabilities.

In total, the novelties are equipped with 27 different sensors, which include numerous ultrasonic and infrared sensors. They help to identify walls, interior items and various obstacles, including objects made of glass. In addition, thanks to sensors, the robot can maintain a constant distance to walls when moving along them, as well as detect sudden changes in height and prevent tipping over (for example, from a ladder).

New vacuum cleaners received side brushes with extended bristles, which allows you to collect more dirt. The rotating brushes are height adjustable for maximum efficiency in picking up debris and dust on a variety of surfaces.

The new series includes the VC-RCX1, VC-RVD1 and VC-RV1 models. The first two come with a charging dock equipped with a waste container. Thus, during recharging, the dirt accumulated in the vacuum cleaner is transferred to a stationary tank, which ensures a constant suction power.

The VC-RCX1 version also has a built-in camera and Bluetooth wireless technology, allowing you to control the operation using your smartphone or tablet.

The VC-RCX1, VC-RVD1, and VC-RV1 robot vacuum cleaners will cost approximately $1150, $860, and $720, respectively.
