Research on species composition and some biological characteristics of some species of Hymenoptera Sphecidae on fruit trees and important industrial trees in Hoa Binh province

31/03/2021
The bee belonging to the Hymenoptera Sphecidae is one of the insect groups that play an important role in agricultural and forestry production and human life, such as in plant pollination, biological struggle and biological indicators. Research on this group associated with specific sites and crops is of great significance in biodiversity conservation, with strong potential for use in biological control and crop pollination, and for economic development under specific conditions of each locality.

In Vietnam, there were previously few and scattered studies on the bee belonging to the Sphecidae family, which focused on investigation and listing of Sphecidae species rather than biological studies, assessment of the current population status, potential use and the ecological relationship between them and plant pests.

From the above urgent issues, the project “Research on species composition and some biological characteristics of some species of Hymenoptera Sphecidae on fruit trees and important industrial trees in Hoa Binh province”, coded ĐLTE00.05 / 19-20, was approved by Vietnam Academy of Science Technology and assigned to the Institute of Ecology and Biological Resources as the lead agency. The project is researched by a group of scientists from the Institute of Ecology and Biological Resources for a period of 2 years (January 2019 - December 2020), headed by MSc. Pham Huy Phong. On January 27, 2021, VAST-level council accepted and evaluated the project as excellent.

The objective of the thesis is to make a list of species composition and study some biological characteristics of the Sphecidae family on some fruit trees and industrial trees in Hoa Binh province, as a basis for the evaluation of their role in the control of pests in these crops and their potential use.

The project has implemented 4 main contents, including: 1- Investigation of species composition and their distribution on some important fruit trees and industrial trees in Hoa Binh province; 2- Research on some biological characteristics of some species of Hymenoptera in the Sphecidae family; 3- Identification of species capable of multiplication for use in biological combat on plant pests and spiders, assessing the current status of the population and their potential to use them, and; 4- Proposals of some measures to conserve and maintain these species.

The topic has obtained the following main results:

  • In terms of science:

+ Identified 19 species of Hymenoptera belonging to 7 varieties in 4 subfamilies of the Sphecidae family in Hoa Binh province and their distribution on 4 plant species: sugarcane, soybean, orange tree and grapefruit tree.
+ Described and announced a new species for science, Chalybion tanvinhensis Pham and Ohl, 2019 and recorded two new species for Vietnam's Hymenoptera, Ammophila globifrontalis Li and Yang, 1995 and Isodontia nigella (Smith, 1856) .
+ Recorded for the first time Melittobia Westwood, 1848 (family Eulophidae) for the parasitic bee system in Vietnam.
+ Provided some new biological data of 5 species of Hymenoptera, Ammophila clavus (Fabricius), Chalybion bengalense (Dahlbom), Sceliphron madraspatanum (Fabricius), Isodontia nigella (Smith), and Sphex argentatus Fabricius for science.
+ The thesis identified 3 species of the Hymenoptera, Sphecidae, Ammophila clavus, Isodontia nigella and Sphex argentatus that have potential for use in pest control and assessed the current status of their populations in nature.
+ The thesis proposed a number of measures to conserve and maintain Sphecidae species, which use pests as food for their larvae in the study area.

  • In terms of application: The thesis has applied the results of scientific research (above) to test breeding 3 species of cephalopods, Ammophila clavus, Isodontia nigella and Sphex argentatus on soybean pest Spondoptera litura (Fabricius ) and on the sugar cane grasshopper Oxya chinensis Thunberg, with initial success.

Project’s products include:
- Data on species composition, some biological characteristics of some species of Sphecidae on fruit trees and important industrial trees in Hoa Binh province; Identify species that can be reproduced for use in biological combat on insect pests and spiders on some fruit trees and industrial plants, and assess the current population status and their potential to use them.
- The specimen set includes 136 species of the Sphecidae family collected in the study area.
- 04 articles published in journals in the SCI-E list, 01 article published in journals in the Scopus list, and 01 article published at domestic conferences. In addition, the project trained 01 postgraduate student.
