Ecologically safe regulation of quantity of arthropods of phytophags of plants of genus Sambucus L.

Abstract

The purpose. To investigate mechanisms of regulation of quantity of hazardous organisms on different kinds of elder in conditions of human settlements of Ukraine. Methods. Conventional methods of faunistic research in entomology, population ecology, protection of plants. Results. The natural flora of Ukraine includes 3 kinds of plants of genus Sambucus L.: black elder, red elder, herbaceous elder. In botanic gardens of Kiev they cultivate nearly 20 forms and varieties of mainly black and red elder. It is determined that there are 9 kinds of arthropods of phytophags from 2 classes, 6 divisions and 8 families which parasitize on them. The most numerous and nocuous of them are: white American butterfly, elder aphid, and web-mite. Conclusions. For protection of plants of an elder from harmful phytophags in conditions of botanic gardens and human settlements it is recommended to use vegetable specimens Phytochelate-1 and Complexon-2p (rape-seed oil with emulsifier and garlic extract with density of 1% (100 g/10 l of water).
