Foreword
This standard replaces GB/T 15792-1995 "rice stem borer investigation and forecast."
This standard compared with GB/T 15792-1995, the main changes are as follows.
a) the scope of the investigation, the type of sampling, the sampling method, the number of samples and so a reasonable adjustment and optimization, to make it more in line with production practices
need;
b) increases the incidence of rice stem borer mode report, unified, standardized data reporting mode;
c) Increase borer different instars developmental duration, extent of occurrence and development of stem borer progress grading index, and stem borer eggs parasitized eggs
Distinguishing features section, provide the basis for the field survey.
This standard Annex A, Annex B is normative appendix, Appendix C, Appendix D and Appendix E is an informative annex.
This standard is proposed and managed by the People's Republic of China Ministry of Agriculture.
This standard was drafted. the Ministry of Agriculture National Agricultural Technology Extension and Service Center.
The main drafters of this standard. Jianqiang, Xia Bing, Liu.
This standard replaces the standards previously issued as follows.
--- GB/T 15792-1995.
Investigation and forecast of rice stem borer
1 Scope
This standard specifies the methods of investigation overwintering rice stem borer, larvae, pupae progress, population density, borer damage rate of return and survey data record
Requirements profile.
This standard applies to rice stem borer investigation and forecast, relevant research and production units can refer to execution.
2 Terms and definitions
The following terms and definitions apply to this standard.
2.1
Last autumn borer local generation 1-2 generations age 3 to 7 larvae enter diapause state, releasing the spring of next year before the diapause behavior.
2.2
Unit area borer larva, pupa and adult number, usually "head/667m2" representation.
2.3
The number per unit area borer egg masses, usually "block/667m2" representation.
2.4
Borer plots generation occurs before or last year, and the winter plowing plots pits, plowing and other irrigation Movies pupation or eclosion of the stem borer is not carried out
Sound borer survival farming activities. Including green manure field, canola fields, wheat fields, and winter vegetable fields not plowed fallow fields, the paddy (a
Season paddy).
2.5
The number of adults and egg each instar larvae, pupae and other insect states surveyed total amount borer insects in the respective proportions of 16%, 50%, 84%
When the insect into the state were the beginning of peak, peak and end of Sheng.
2.6
Damage by stem borer, rice sheath blight exhibit, dead heart, booting dry, white ear number per plant, insect strain injury symptoms such as total number per plant survey hundred
Fraction.
3 wintering population density and mortality survey
3.1 investigation time
1 survey before winter, combined with the last borer damage rate. After wintering survey 1, before the local paddy irrigation or tillage of overwintering larvae
Pupa beginning of peak perform.
3.2 Survey Methods
3.2.1 Effective Insect field investigations within
Representative effective insect selected fields (including fallow fields and spring crop fields) 10 ~ 15, the total survey area of \u200b\u200bnot less 1hm2, on behalf of the
Surface area of \u200b\u200bnot less than 1000hm2. Using checkerboard sampling, each sampling point 20 fields, each point 0.4m × 0.5m.
