TAILIEUCHUNG - Summary of Siological doctoral thesis: Studying on the component of honey bee species (Hymenoptera: Apidae) and the ability to use some species as an indicator estimating environmental pollution on affected ecosystems in the North of Vietnam

Studying species component, distribution of honey bee species belonging to the family of Apidae, analyzing the ecological relations and determining for using some honey bee species as an indicator of environmental pollution on the affected ecosystems (farm ecosystems, perennial garden ecosystems, cultivated forest ecosystems and evergreen forest ecosystems) in some provinces in the Northern Vietnam, contributing to the conservation of honey bee species and producing highquality honey products for the economic development of local people. | MINISTRY OF EDUCATION AND VIETNAM ACADEMY OF SCIENCE TRAINING AND TECHNOLOGY GRADUATE UNIVERSITY OF SCIENCE AND TECHNOLOGY ----------------------------- NGUYEN PHUONG MINH STUDYING ON THE COMPONENT OF HONEY BEE SPECIES HYMENOPTERA APIDAE AND THE ABILITY TO USE SOME SPECIES AS AN INDICATOR ESTIMATING ENVIRONMENTAL POLLUTION ON AFFECTED ECOSYSTEMS IN THE NORTH OF VIETNAM SUMMARY OF BIOLOGICAL DOCTORAL THESIS Major subject Entomology Code 62 42 01 06 HA NOI 2017 The name of postgraduate training institution Graduate University of science and technology Vietnam Academy of science and Technology.

The imperation of the thesis Honey bee family Apidae is the largest and the most diverse anout species component in Apoidea with more than 5700 described species in which some of them had been bred for honey production. Every year Vietnam produces nearly 20 000 tons of honey and 80-85 of total honey production is exported. Many species of honey bee Apidae are important pollinators for major food crops and industrial crops on the world. However populations of indigenous honey bee species may also be shrinked. The causes may be due to the shortage of their foods and the effects of pesticides. In addition residues of pesticides remaining in agricultural products influence over not only human beings and domestic animals but also many species of honey bee. Some studies have shown that composition of heavy metal and metalloids which are cumulated inside bodies of honey bee species due to the consumption of food from the polluted environment could
