1 Scope
Specification for spider monitoring and investigation
VYT615—2002
This standard specifies the following items and specifications, including systematic investigation, general method, monitoring data collection, and summary method.
This standard is a systematic investigation of spider bacteria. 2 Terms and definitions
The following terms and definitions apply to this standard.
Systematic investigation
To observe the occurrence, development or status of a disease in a region, a fixed-point, fixed-pair, or fixed-point investigation is conducted. 2. 2 Field investigation
To understand the occurrence of a disease in a region, a large-scale multi-point investigation is conducted. 2.3
Preventive loss
The yield loss of crops after disease prevention and rodent control. The yield benefit of the control area is higher than that of the small control area. 2.4
Actual loss
The yield loss caused by residual disease and rodent control after disease control. 2.5
Insect field rate
The percentage of the number of plots in the survey area of ​​the enterprise. 2.6
Insect population density
The total number of insects in the unit sample area. It is expressed as the number of insects per 83.3 cm. 3 Safety degree grading index
The degree of spider occurrence is divided into 5 levels, which should be determined by the average or available density during the safety period. The service level index is shown in 1. Table" Table of spider occurrence degree classification standards

The return rate is drawn every 5 people. Please conduct the investigation between 8:00--10:00 and 5:00-18:00.NY/T615—2002
4.2 Investigation plots
Choose local areas with serious dust pollution in previous years and representative dust pollution environments. Use no less than (2×S) plots for systematic observation.
4.3 Investigation method
Collect samples at 5 points for each block of daily effective load, and report 33,3sm single line length, return period with oral measurement and recognition number, after the festival, 33,3c×17 and fixed with guilty conscience or eat plastic shop, take a single point at the root zone, the branch can be gently pressed and twisted, you can change it several times, the oil method can change the number of spider species, the fruit clothes will be 2.

According to the local actual occurrence situation, the survey is divided into 4 times in autumn, return period, extraction period, pregnancy period, and the road car time should be roughly between these auspicious times.
