This document replaces GB/T 27772-2011 "Density control levels of vector flies". Compared with GB/T 27772-2011, In addition to structural adjustments and editorial changes, the main technical changes are as follows. a) In the Terms and Definitions, the definition of flies was deleted (see 3.1 of the.2011 edition), and the positive rate of flies in rooms was changed to indoor adult flies. Positive rate (see 3.3, 3.4 of the.2011 edition), add fly breeding path index (see 3.6), change fly prevention facilities to fly prevention facilities Qualification rate (see 3.7, 3.2 of the.2011 edition); b) Added the inspection method for indoor adult flies and fly breeding areas (see 4.1, 4.2), and changed the inspection method for fly prevention facilities (see 4.3, 4.2 of the.2011 edition); c) Changed the index values of the three levels of indoor adult fly density control level A, B, and C (see 5.1.2, 5.1.2 of the.2011 edition); added A, B, C. The third-level outdoor fly breeding path index value replaces the outdoor fly breeding rate (see 5.1.4, 5.1.3 of the.2011 edition); Changed the unit fly density control level (see 5.2, Appendix A of the.2011 edition); d) The sampling quantity requirements have been changed (see 6.2, 6.2 of the.2011 edition); e) The sampling requirements for evaluating the control level of fly density in cities and towns have been changed (see Appendix A, Appendix B of the.2011 edition), and fly control has been added. Facility requirements (see Appendix B). Please note that some of the contents of this document may involve patents.

Density control level of vectors Flies1 ScopeThis document specifies the control level, sampling requirements and comprehensive evaluation of indoor adult flies, fly breeding areas and fly control facilities in towns and units, and describes A method for checking the fly density control level was developed. This document is applicable to the evaluation of fly density control levels in towns and units.2 Normative referencesThe contents of the following documents constitute essential clauses of this document through normative references in this document. For referenced documents without a date, only the version corresponding to that date applies to this document; for referenced documents without a date, the latest version (including all amendments) applies to This document. GB/T 23796 Methods for monitoring density of disease vectors - Flies3 Terms and definitionsThe following terms and definitions apply to this document. 3.1 units The specific places to be evaluated, such as restaurants, shopping malls, supermarkets, government agencies, enterprises, hotels, farmers' markets, hospitals, schools, construction sites, Fields or stations, residential areas, garbage transfer stations, public green spaces, public toilets, etc. 3.2 During the fly activity season, effective measures were taken to compare the indoor adult fly positive rate with the positive fly density, fly breeding path index, and fly prevention index. The facility qualification rate is controlled within the corresponding indicators. 3.3 The percentage of standard rooms with adult fly activities indoors to the number of standard rooms inspected. 3.4 The mean number of adult flies in a standard room with indoor adult fly activity. 3.5 fly breeding sites Containers or places containing breeding organisms such as decaying animals, decaying plants, human excrement, livestock excrement and organic waste that may breed fly larvae or pupae. 3.6 During the inspection, the number of positive breeding organisms of fly larvae or pupae was found in every 1000m of the external environment path. 3.7 The percentage of places with qualified fly-proof facilities to the total places that should be equipped with fly-proof facilities. ......Tips & Frequently Asked Questions:Question 1: How long will the true-PDF of GB/T 27772-2025_English be delivered?Answer: Upon your order, we will start to translate GB/T 27772-2025_English as soon as possible, and keep you informed of the progress.
