Foreword
This standard replaces GB/T 15794-1995 "planthoppers investigation and forecast."
This standard compared with GB/T 15794-1995, the main changes are as follows.
a) to ensure the accuracy of the survey on the basis of the survey, sampling method, the number of samples and so a reasonable adjustment and optimization, so that
More in line with the requirement of production;
b) to measure light trap set up the environment for the quantitative definition of attracting insects to improve efficiency, the results more representative;
c) the use of sub-grid notation statistics summer insect trap lamp volume fall, "sweep net method" or "visual method" survey wintering area seedling, water moist Dish
Sign inner wall check method field planthopper insect Survey, more operational, more efficient;
d) increase planthoppers occurrence degree classification index, improving the basis for the field survey;
Case mode report e) increase the occurrence of rice planthopper, unified, standardized data reporting mode.
This standard Annex A, Annex B is normative appendix, Appendix C, Appendix D, Appendix E is an information appendix.
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.

Planthoppers investigation and forecast
1 Scope
This standard specifies the methods of investigation planthoppers winter, lights lure measure, the amount of field insects, predators and health hazards and forecasting data compilation and
Filing requirements.
This standard applies to planthoppers 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
Planthoppers before the onset of winter migration way through, looking for low latitude Rice feeding activities, to avoid the harsh winter environment impacts their survival
behavior.
2.2
Planthoppers can safely spend the winter in the area known as planthoppers wintering area. Usually it refers to the south of latitude 23 °, the lowest monthly average winter temperature
Temperature above 12 ℃, the average daily temperature is below 10 ℃ for several days does not exceed the annual 10d, and there ratoon rice or rice, shattering self rice
Growth areas.
2.3
When the rice harvest scattered on paddy rice or ridge natural germination and growth of rice.
2.4
The residue after rice harvest rice sprout internode pile portion of the lower section tiller, tillers these can finally heading, flowering, seed.
2.5
Planthopper nymph to develop to 3 years old (including 3 years old) previous nymphs.
2.6
Planthoppers 3 instar nymphs.
2.7
According to the results of light trap, from the amount of adult planthoppers appear sudden increase in peak day to day after the sudden reduction so far is a peak period, peak period of up to the amount of insects
Date for peak day; distance between the previous peak within 3d projection Save day and after a sudden increase in peak day (including 3d) is recognized in the same peak.
2.8
Local adult emergence peak is determined based on the results of the field survey, the amount of adult emergence date for most of the field peak day, before the adult peak
The amount of future amount of insects suddenly increased peak period of stable field peak.
2.9
After the adult peak corresponding field when the sudden increase in the amount of eggs, compared with peak spawning.
