Clean Ecological Methods of Struggle with Urban Pests

Advance of pest diversity on urban area is reality of modern time. Actual biological technologies are unable to prevent this process. Sometimes struggle leads to negative results in particular under use of chemical pesticides. Use of clean ecological methods must be strategy of nearest future. The basis of such a technology must be imitation of wild nature processes. There are 4 groups of such a technique. They are: ecological, genetical, chemical-and-ecological, physical-and-ecological. Ecological ones are based on natural intra species relations. They are: competition, host-parasites and predator-prey. The use of competition is only way to complete suffocation of unprofitable species by less dangerous one. Genetically methods are based on selection and gene engineering. Chemical-and-ecological methods are based on use of natural biological activity compounds of their analogs. Such compounds are: hormones, anti hormones, biological toxins, attractants and repellents. Ecological-and-physical methods are based on use of natural fields such as acoustical (sound, ultrasound, infrasound) and electromagnetic. Only composition and rotation of all the methods may become the basis for effective control of urban pest populations.
