Foreword

This document complies with the provisions of GB/T 1.1-2020 "Standardization Work Guidelines Part

1.Structure and Drafting Rules of Standardization Documents". Drafting. This document replaces GB/T 15792-2009 "Specifications for Monitoring and Forecasting Rice Stem Borer". Compared with GB/T 15792-2009, except for the structure... Aside from adjustments and editorial changes, the main technical changes are as follows:

a) The English translation of the term "overwintering" has been changed, and the terms and definitions of "insect population density" and "egg mass density" have been removed (see 3.1,.2009). Versions

b) Added a classification index for the occurrence severity of rice stem borer (see Chapter 4);

c) The method of straw stripping in the overwintering survey has been removed (see

3.2.2 in the.2009 edition);

d) The adult insect monitoring method was changed, the incandescent lamp monitoring method was removed, and conventional monitoring lamps, intelligent insect monitoring lamps, and high-altitude monitoring lamps were added. Monitoring methods for lamps, conventional sex decoys, and automatic counting sex decoy monitoring equipment (see Chapter 6, Chapter 5 of the.2009 edition);

e) The field survey methods were changed, including "larval and pupa development progress survey", "egg mass density and hatching progress survey", and "stem borer infestation rate and each generation". The "Population Density Survey" has been merged into the "Systematic and Field Survey," and related content has been streamlined (see Chapter 7, Chapter 4 and Chapter 6 of the.2009 edition). Chapter 7);

f) The forecasting methodology was changed, merging "occurrence period forecast" and "occurrence severity forecast" into "forecasting" (see Chapter 8,.2009). Chapter 8 of the edition);

g) The data collection, aggregation, and reporting methods have been changed, with "Data Recording and Archiving" renamed to "Data Collection, Aggregation, and Reporting," and additional features added. The methods and requirements for data collection, aggregation, and reporting are outlined (see Chapter 9, Chapter 9 of the.2009 edition).

1 Scope

GB/T 15792-2026 is the Chinese national standard covering monitoring the rice stem borer - the pheromone trapping and the dissection of stems, the generations through a season and the forecast of when the larvae will be vulnerable to treatment. It replaces GB/T 15792-2009 and has been in force since 1 October 2026. It was issued on 31 March 2026 and takes effect on 1 October 2026, replacing GB/T 15792-2009. The document is under the responsibility of the Ministry of Agriculture and Rural Affairs. This page is published from the official record of the 2026 edition; the clause text of a standard this recent is not yet in circulation, and the figures, limits and tables it contains are those of the document itself, delivered in full with the English translation.

This document defines the terminology and definitions for the rice stem borer, specifies the grading indicators for occurrence severity, and describes the methods for overwintering surveys, adult monitoring, and system management. It integrates methods such as field surveys, forecasting, and information reporting. This document applies to the monitoring and forecasting of rice stem borers.

4.Occurrence severity grading indicators The severity of rice stem borer infestation is classified into five levels according to Table 1.mild infestation (Level 1), moderate infestation (Level 2), and moderate infestation (Level 3). Predominantly occurring (Level 4), major occurrence (Level 5).

5 Survey of overwintering insect population density and mortality rate

5.1 Survey period Pre-winter surveys are generally conducted from October to December and can be combined with surveys of the last generation of stem borer infestation rates; post-winter surveys are generally conducted before irrigation and plowing of local paddy fields. Or it can be carried out during the peak pupation period of overwintering larvae.

5.2 Survey Methodology Select 10-15 representative and diverse effective source fields for insect infestation, with a total survey area of no less than 1 hm

2.Use a checkerboard sampling method. Ten sampling points were taken from each field, with each point covering

0.5 m^2. The number of exposed rice stubble, live (dead) rice stem borers, and live (dead) pupae were counted for each type of field. Simultaneously, other stem borers, such as the rice stem borer, were investigated in the rice stubble, and the proportion of the rice stem borer was calculated. The insect population density and weighted average were calculated using equations (1) to (4). The insect population density, pupal mortality rate, and weighted average pupal mortality rate were recorded in Tables A.1 to A.3 of Appendix A.

7 System and Field Survey

7.1 Survey period From the time the rice was transplanted until it was harvested at maturity, a survey was conducted every 7 days, with an egg count survey conducted during the rice seedling stage.

9 Data collection, summarization, and reporting

9.1 Data Collection Collect and organize local rice planting area, main varieties, sowing period and local meteorological data.

9.2 Data Summary Compile statistics on the occurrence and control of the rice stem borer, summarize its characteristics, analyze its causes, and fill in the annual occurrence statistics of the rice stem borer according to Table C.2. Meter.

9.3 Data Reporting Plant protection agencies at all levels shall fill out relevant reports on rice stem borer according to Appendix A, Appendix B, and Appendix C every year and submit them to the superior monitoring and reporting department.
