Abstract

The results of long-term entomological observations at nurseries and in the collection greenhouse of PABSI are presented. The species composition of pests in the collections of open and closed ground of flower and ornamental plants in thePolar-AlpineBotanical gardenwas determined. The dominant invertebrates in nurseries are: Deroceras reticulatum Mtill., Eriophyes padi (Nal), Macrosiphum rosae L., Philaenus spumarius L., Gonioctena quinquepunctata F., Gonioctena pallida L., in greenhouses - Brevipalpus obovatus Donn., Neomyzus circumflexus Buckt., Myzodes persicae Sulz., Heliothrips haemorrhoidalis Bouche. Long-term observations of the state of flower and ornamental plants in greenhouses have shown that not only the species composition changes, but also the status of pests. An important role in the formation of the artificial biocenosis of the greenhouse is played by the food preferences of phytophages. Regular surveys revealed the presence of pests on plants of 41 families. The distribution of plants by the degree of pest population depending on the life form is presented. The most actively populated by the species of tree and shrub groups. The presented species composition of pests of flower and ornamental plants of open and closed ground can not be considered definitively studied, since changes in the trophic relationships of pests were noted during the study period.
