Purpose: highlighting the current status and role of Orthoptera insects in natural and agriculture ecosystems from the Republic of Moldova.
Objectives: species identification and determination of Orthoptera insects from the Republic of Moldova and analysis of their zoogeographical distribution, trophy spectrum and their habitats; investigation of Orthoptera insects from different scientific and landscapes reserves from the Republic of Moldova; the significance of Orthoptera insects in the biocoenoses; elaboration of recommendations for monitoring, estimation and improvement of harmful grasshoppers species group.
Scientific originality of work. For the first time where done an amply review of Orthoptera species from the Republic of Moldova which is listing 113 species. The subfamily Gryllomorphinae, 10 genera and 35 species are new for the fauna of the Republic of Moldova. There are also done dates belonging biogeographically distributions on the types of habitat, vital form and food spectrum. Three species have been identified rare and endangered grasshoppers in the Republic of Moldova and in other European countries. These species (Saga pedo, Onconotus servillei and Gampsocleis glabra) are proposed to be included in the Third edition of the Red Book of Moldova.
Theoretical significance. The research has made a significant contribution to the study of insect from Orthoptera order in the Republic of Moldova. The obtained dates about place and role of grasshoppers in ecosystems of each species present the base of the Animal Cadastre of the Republic of Moldova and contribute to solving problems related to integrate environmental monitoring.
The practical value. The main results of the thesis are part of the theme of academic and applied scientific study of the Institute of Zoology of the ASM. Research results will contribute to increasing theoretical and empirical heritage, the diversity of fauna, seasonal dynamics, trophy spectrum, spatial structure in bio interference geographical zone of populations of Orthoptera insects.
Implementation of scientific results. The obtained results are used in preparing of the Animal
Cadastre of the Republic of Moldova and the third edition of the Red Book of Moldova. Also, the dates of
pest and invasive species are utilised especial courses in Agriculture State University of Moldova at the
speciality “Plant Protection” and in elaborating of measures of fight in forests tree nursery and green
