Foreword
This standard is one of the national crop pest investigation and forecast series.
This standard replaces GB/T 15793-1995 "leafroller investigation and forecast."
This standard and GB/T 15793-1995 compared to the main changes are as follows.
--- In the original "leafroller investigation and forecast" basis, adding the standard cover, preface; text all the relevant survey form
Move the Appendix;
--- Summary grassroots investigators throughout many years of experience, it does not affect the accuracy of the survey, based on the specifications of the original investigation were appropriate sample size
Degree cut;
--- For the new features in recent years occurred leafroller, focusing on eggs, larvae survey methodology, the number of samples to be adjusted to improve the data on behalf of the
Table sex;
--- Normative annex to regulate leafroller occurrence data format, ensuring data collection consistency; informative appendix as a guide throughout
Leafroller Investigation and Prevention provide references.
The Standard Annexes A and B are normative appendix Appendix C is informative appendix.
This standard is proposed and managed by the People's Republic of China Ministry of Agriculture.

In the local insect overwintering insect to next spring's major areas.
2.2 investigation time
After the winter before adult emergence.
2.3 Survey Methods
Select paddy, green manure fields and Tanabe, gutter and other major overwintering sites, sampling a total of more than 20m2, investigation rice pile, ratoon rice, rice down the valley, winter
Rice and larvae and pupae overwintering weeds on 1 to 2 times, death statistics, the number of live larvae and pupae and parasitic number, the findings credited
