Pheromones and chemical mutagens No. 3

The use of this method for pest control is currently hampered by the lack of drugs that provide a gradual release of pheromone, which could be used in large areas. However, several effective drugs have already been created that use hollow fibrous and laminated plastics and microcapsules for long-term dosing of the drug into the atmosphere. The use of drugs containing sex pheromones and preventing the mating of pests proved to be significantly more effective than the use of insecticides. As shown by the specialists of the Institute of Tropical Products in the UK, it is enough to use a pheromone in the amount of 10 g per 1 ha to destroy the pink boxworm throughout the season. At this rate, the pheromone method is already competitive in price with conventional insecticide application methods. Pheromone preparations based on hollow fibrous plastics have been officially approved for pest control of artichokes in the United States.


In the UK, pheromone-based drugs to prevent insect mating have been successfully tested on plantations of corn, rice, grapes and other agricultural crops. In order for methods based on the use of pheromones and other semiochemical substances to really find wide application, it is still necessary to carry out a significant amount of fundamental research, as well as solve problems of an economic and organizational nature. This kind of research is absolutely necessary for the practical implementation of the program of transition from the use of insecticides, which are sufficiently toxic means of destroying agricultural pests, to pheromones, which are safe means of regulating the number of insect pest populations. These studies promise to bring about a radical revolution in the field of agricultural chemicalization in the future. The use of pheromones and the abandonment of a number of insecticides are likely to have a great positive effect from the point of view of environmental protection. Scientists suggest that in many cases, the "chemical language" of insects is a series of strong odors produced in various combinations. For example, pheromones that attract insects of the opposite sex are often mixtures of four or five compounds. In order for signals to acquire semantic meanings for insects, these substances must be released in a strictly defined order and in certain proportions. Now scientists in several countries are trying to unravel the biochemical mechanism by which insects "decode" chemical signals. It is believed that in the future it will be possible to create synthetic pheromones that distort the normal signals of insects. 1xBet Promo Codes and Bonus Offers in Valid Today.
