The article presents studies on the impact of ultraviolet light-emitting diodes and silicon-containing preparation “Nanosilicon” on the germination of seeds of meadow clover ‘Ranny 2’, alfalfa (Medicago varia) ‘Victoria’ and fodder galega ‘Yaltinsky’. The purpose of the studies was to investigate the synergism of the simultaneous exposure to ultraviolet radiation and nanosilicon to increase the rate of seed germination. The study was investigating ultraviolet radiation zone “A” (UV-A) for a period of 5 minutes. The average irradiance was 3.137 W/m2. A decrease to 2-3% of the amount of hard seeds of meadow clover was noted in the variants: first treatment was with ultraviolet light, and then with “Nanosilicon” (UV irradiation + “Nanosilicon”) and vice versa: first, treatment was with “Nanosilicon”, and then with ultraviolet (“Nanosilicon” + UV irradiation). In addition, a decrease to 7.9-9.5% of the seeds contamination was detected for fodder galega in almost all studied variants. The use of the preparation “Nanosilicon” and UV radiation on the seeds of alfalfa contributed to an increase in the length of the sprout up to 2.4 cm, the root up to 1.5 cm, the degree of development of seedlings up to 3.0 points, the growth rate up to 29.8%.
One of the main pests of bee colonies is the large wax moth, which can destroy up to 30 percent of the honey in the hive. Controlling the behavior of living objects can be based on their positive or negative response to optical radiation characteristics such as spectrum and exposure. Many insects see ultraviolet radiation. Authors suggest using an environmentally friendly method to attract butterflies with optical radiation. (Research purpose) The research purpose is in developing digital electrical technologies using a microprocessor-based automated system that allows controlling the behavior of large wax moth butterflies (Galleria mellonella) by implementing attractive characteristics of optical radiation. (Materials and methods) Authors controlled the behavior of a large wax moth using a developed automated system for maintaining the required duration of the experiment and optical radiation parameters. The main element of the system is the ATmega328 microcontroller, the program for which was written using the visual programming of FLProg 5.3.0. (Results and discussion) The use of digital electrotechnologies using the developed microprocessor automated control system on the ATmega328 microcontroller and assembled on the Arduino Uno Board makes it possible to implement energy-saving environmentally friendly light electrotechnologies for controlling the behavior of large wax moth butterflies. Regardless of the duration of the experiment, Galleria mellonella butterflies prefer radiation with a wavelength of 400 nanometers. (Conclusions) The experiments confirm that the radiation with a wavelength of 400 nanometers lasting 10 minutes at a temperature of 32 degrees Celsius and a humidity of 60 percent was attractive. These comfortable spectrum parameters allow to control the behavior of Galleria Mellonella by luring butterflies to a specific location in the hive.
Wax moth is one of the main pests of bee colonies. Bee moth larvae have in their chemical composition many substances that are necessary for the preparation of drugs of the widest range of action. Beekeepers solve the problem of better control of greater wax moths using chemical, biological and other methods. The efficient methods to control Galleria mellonella include physical methods: temperature, radiation, etc. The purpose of this paper is to find the most effective optical radiation for a greater wax moth (Galleria mellonella L.), in which the productivity of bee colonies is maximally preserved, and unscathed G. mellonella larvae can be used to manufacture pharmaceutical preparations and biologically active supplements. The object of research is the Greater wax moth (eggs, larvae, pupae, and imago). We have developed a structure for determining the attractiveness of the optical radiation of different wavelengths for imago of greater wax moths. We found that the optical radiation in the wavelength range of 400…435 nm is the most attractive because it attracted a greater wax moths and therefore the number of eggs laid under the influence of this light was 1.5…2 times higher compared to radiation 491, 546 and 491 nm.
The authors found out that the greater wax moth (Galleria mellonella) harmed bee colonies by destroying up to 30 percent of honey in a beehive. They studied the results of experiments on controlling its behavior using a developed automated microprocessor system that maintained optical radiation sources duration.(Research purpose) To develop light technologies using a microprocessor-based automated system that allows controlling Galleria mellonella behavior by realizing attractive optical radiation characteristics.(Materials and methods) Galleria mellonella behavior was controlled by an automated system that the authors worked out for maintaining the required duration of the experiment and optical radiation parameters. The ATmega328 microcontroller was chosen as the main element of the developed microprocessor automated system. The authors created a program for it using visual programming FLProg version 5.3.0.(Results and discussion) The authors found that, regardless of the experiment duration, Galleria mellonella butterflies prefered radiation with 400 nanometers wavelength.(Conclusions) The authors determined that radiation with 400 nanometers wavelength and 10 minutes duration was attractive. They showed the ability to control Galleria mellonella behavior, luring butterflies to a specific place in the beehive with comfortable spectrum parameters. An automated system for controlling the greater wax moth butterfly behavior was developed on ATmega328 microcontroller by implementing attractive optical radiation characteristics.
