Foreword
This standard replaces GB/T 15802-1995 "Investigation and specification of cotton mite measurement and forecasting".
This standard and GB/T 15802-1995 compared to the main changes are as follows.
a) increased the forecasting and forecasting method of mite mite in cotton, the name "cotton mite forecasting survey" to "cotton mite forecasting technical specifications";
b) increased the spider mite pattern report, the main influencing factors and so on;
c) the original version of "cotton field insects, natural enemies and cotton damage investigation", the current version to "cotton field system survey", "field survey" and "days
Enemy investigation "and other parts of the original version of the observation of the nursery set in the system survey, the original version of" field census "
"Each type of field should be census more than 3" to "large area before the prevention and control, census more than 10 representative cotton field";
d) the original version of the spring insect source base survey Southern cotton survey object for the broad bean, the current version to weeds.

Technical specification for measurement of mite of cotton
1 Scope
This standard stipulates the survey of cotton insect mites in spring, the investigation of cotton field system, field survey, natural enemy investigation and forecasting method.
The degree of damage and the degree of occurrence of damage and damage to the loss of statistics, report data summary and reporting and other technical content.
This standard is applicable to the investigation and forecast of cotton mites in cotton fields in China.
Investigation on insect base in spring
2.1 Survey time
In March, the average temperature was stable at 6 ℃ above the survey, a total of 2 surveys, about 10d interval.
2.2 Survey object
Northern cotton area mainly in the wheat survey; southern cotton area mainly in the weeds on the investigation, in the cotton and cotton near the field, select the 3 ~ 5
Main host weeds (common are mother-in-law, Buddha, verbena, snake berries, motherwort, black raspberry, scenery roe, wild alfalfa, dandelion, etc.).
2.3 Methods of investigation
A total of 50 species and 100 plants were surveyed by 5 sampling methods in each field. Weeds were randomly sampled.
Weeds were investigated for 50 to 100 strains. Record the number of mites, the number of insects. The average of the two surveys was used as the spring cotton mite
The results are shown in Table A.1.
3 cotton field system survey
3.1 Investigation of plots
According to the characteristics of the local cotton mite, select the local representative of the cotton field 3 to 5, each field area above 667m2.
Respectively, in the seedling stage, bud flower period, flower bunch period (see Appendix B) each set a survey field. Conditional areas can be set to observe the garden, that is, in the fertilizer line
Good, around the weeds are more conducive to the occurrence of cotton mites under the conditions of the observation nursery, an area of 350m2.
3.2 Survey time
Starting from the cotton Qimiao, every 5d investigation once, to Tucui Sheng period.
3.3 Methods of investigation
Using "Z" type of sampling, according to the size of the plots reasonable arrangements for samples, each field to take 50 cotton. Seedling check the whole plant; buds, each strain
The number of mites, the number of mites and the level of mites were recorded in the leaves of the main stem (the main stem).
(1) Calculate the average number of mites, recorded in Table A.2.
3.4 Calculation index of mite grazing index and average number of mites
3.4.1 indicators of mites grading
Level 0. No harm;
Level 1. leaves have sporadic yellow patches;
Level 2. Red patches account for 1/3 of the leaves;
Level 3. Red patches account for 1/3 of the leaves.
3.4.2 Calculation formula of average number of mites
The average number of mites is calculated according to formula (1).
M = Σ
