The project is aimed to yield the composition and distribution of solitary wasps of the family Sphecidae in several provinces of the northwest part of Vietnam, new species to science and new species to Vietnam, and addition of some new biological, ecological, and behavioral characteristics of the mud dauber wasp S. madraspatanum. These results will be scientific base to next studies on the family Sphecida in the future. | MINISTRY OF EDUCATION VIETNAM ACADEMY OF SCIENCE AND TRAINING AND TECHNOLOGY GRADUATE UNIVERSITY OF SCIENCE AND TECHNOLOGY PHAM PHONG HUY RESEARCHS ON THE COMPOSITION OF SOLITARY WASPS OF THE FAMILY SPHECIDAE HYMENOPTERA APOIDEA IN SEVERAL PROVINCES OF THE NORTHWEST PART OF VIETNAM AND SEVERAL BIOLOGICAL ECOLOGICAL AND BEHAVIORAL CHARACTERISTICS OF THE MUD DAUBER WASP SCELIPHRON MADRASPATANUM FABRICIUS 1781 Major Entomology Code 9420106 SUMMARY OF THE PHD THESIS Ha Noi 2020 The research was completed in Graduate University of Science and Technology Vietnam Academy of Science and Technology Supervisor 1 .

Importance of the research Solitary wasps of the family Sphecidae are important in several habitats and most are useful to people s aim. They are prey specialists and pollinators but some of them are biomarkers for several ecosystems. Surveys and studies on the composition biology ecology and habits of sphecid wasps of this family are necessary and bring scientific and real meanings to highlight their valuableness in ecosystems Bohart và Menke 1976 Buck 2003 . Studies on the sphecid wasp fauna of Vietnam are hirtheto limited. These focus only surveys of the composition of the sphecid wasps. 24 species and 3 subspecies of the family Sphecidae are as to now recorded for the Vietnamese fauna. The number of sphecid wasps of Vietnam 24 is much less than that listed in the world 789 Pulawski 2019 . The northwest part includes 6 mountainuos provinces in which there is a variety of climate and topography. Its border line is with Chiness and Lao neighbours and the area is on the eastern side of the .
