GB/T20879:2007 ISPMs X0.5 and XY/T17052009 shall apply to the terms and definitions specified in this standard. 4 Initiation of risk analysis
4.1 Initiation
The following reasons require the risk analysis of red palm weevils to be conducted or to be updated: the introduction of red palm weevils into the endemic area; the continuous interception of red palm weevils in the endemic area;
--the sudden outbreak of red palm weevils in the endemic area requires the formulation of appropriate management measures; the introduction of red palm weevils as host plants of commodities into the endemic area or the transit transportation of red palm weevils as host plants of commodities requires the formulation of appropriate quarantine measures;
--the red palm weevils are more destructive in areas outside the risk analysis area than in their place of origin. 4.2 Collect information
Collect relevant risk analysis reports already available at home and abroad and verify their validity. If risk analysis of red palm weevils has been conducted in the risk analysis area and the risk analysis is still valid, the risk analysis shall be terminated. Risk analysis of red palm weevils in other places shall be used as a reference. Collect relevant information such as the biological characteristics, ecological characteristics, distribution and entry and exit plant quarantine of red palm weevils. 5 Risk assessment
5.1 Assessment of suitability
5.1.1 Possibility of survival
5.1.1.1 Environmental conditions
Based on the biological and ecological characteristics of red palm weevils and the natural conditions such as climate, water and soil in the risk analysis area, determine whether red palm weevils can complete their life history in the risk analysis area. If they can complete their life history, continue the risk assessment from 5.2; if they cannot complete their life history, conduct the assessment specified in 5.1.1.2. 5.1.1.2 Host distribution
NY/T 1706—2009
Determine whether the risk analysis area has hosts of red palm weevils. If so, continue the risk assessment from 5.2; if not, conduct the assessment specified in 5.1.2. 5.1.2 Host transfer
Investigate whether there is an event of host transfer after the red palm weevils are introduced into a certain area. And evaluate the possibility of the above event in the future based on its biological and ecological characteristics
If there is no such event and there is no possibility of the above event, stop the risk analysis and classify it according to the lowest risk level specified in 5.3; if there is the above event and/or the possibility of the above event, continue the risk assessment. 5.2 Risk assessment
5.2.1 Representation of risk
Risk size is represented by risk measures and risk index is expressed in words. The maximum value of R is 100. 5.2.2 Composition of risk index
R consists of four parts: the human invasion index (R), adaptability index (R:), spread index (R,) and harmfulness index (R), which are calculated by the following formula: R=R-R+R,+R.
5.2.3 Determination of risk index
Human invasion, adaptability, spread and harmfulness are the principle layers, and each principle layer is set with the following indicators: The first-level indicators are set with the following indicators: The parameters and their assignments of indicators are shown in Appendix A. According to the parameters and their assignments of each indicator, the corresponding scores of the red palm weevil under the small indicators are given (refer to Appendix A when determining the scores): All the scores of the principle layer are added to get the indexes RR, R, and R of the whole principle layer. The risk index R is calculated according to the formula given in 5.2:
The following principles must be followed when assigning the score:
·Indicator R, r-domestic distribution x prediction should be based on a relatively mature system, such as Climex, Clinate, MARYBLYT, etc.
·Indicator R, in particular, whether the species is prone to resistance and the difficulty of controlling resistance should be considered. If it is indeed impossible to obtain the information required to determine a certain indicator parameter or the cost of obtaining the information required to determine a certain indicator is too high, the indicator can be skipped. However, the number of first-level indicators skipped in each criterion layer shall not exceed 20% of all second-level indicators in the criterion layer, and the number of second-level indicators skipped in all criteria shall not exceed 10% of all second-level indicators. The skipped indicator is assigned the highest value of the corresponding score. 5.3 Classification of risk levels
The size of the root K is divided into red and brown elephant risk levels. This standard defines three risk levels: very high, high, medium and low. The classification standards are shown in Table 1. Table 1 Determination of risk level
Risk level
Classification standards
3022R-15
R, R2, R:, R, any index is full, regardless of the size of other indexes, the total risk level is classified as "very high" RR:, R:, R any index is zero, regardless of the size of other indexes, the risk level is classified as "low". RR, RR, medium, full value and zero index appear at the same time, zero index takes precedence. Risk level is classified as "low". 6 Risk management suggestions
According to the risk level.The measures and strengths for controlling the red palm weevil and quarantine its host are proposed for reference by decision-making departments. The overall principles for risk management recommendations are as follows: NY/T 1706—2009 The risk level is extremely high: Plants, plant products, soils, etc. that can carry red palm weevils (various forms) in the epidemic area (within the risk analysis area) are strictly prohibited from being transported to non-epidemic areas (within the risk analysis area). The most stringent quarantine measures should be implemented for plants and plant products that can carry red palm weevils (various forms); strict precautionary measures should be taken during the transit transportation of plants, plant products, soils, etc. that can carry red palm weevils (various forms) to strictly avoid possible escape, and transit transportation is not allowed; various effective measures should be taken at an acceptable cost level to control the red palm weevils in the epidemic area. Fight fire with all efforts
When the risk level is high, plants, plant products, soil, etc. that can carry red palm weevils (various forms) in the risk analysis area shall be transported to non-epidemic areas (in the risk analysis area) or plants and plant products that can carry red palm weevils (various forms) introduced from outside the risk analysis area shall be strictly inspected and quarantined. If carriers are found, they shall be thoroughly treated for pests before they can be transported: adequate measures shall be taken to monitor the presence of red palm weevils during transportation, transfer, and transit transportation; various effective measures shall be taken at an acceptable cost level to fight fire or control palm weevils in the epidemic area.
When the risk level is medium, the day, area, batch, and quantity of introduction or transfer shall be appropriately restricted; appropriate measures shall be taken during introduction, transfer, and transit transportation to monitor the presence of red palm weevils; appropriate measures shall be taken at an acceptable cost level to control and monitor the red palm weevils in the epidemic area and to prevent the continuous expansion of the occurrence area. The risk level is low. Plants, plant products, soil grafts, etc. that may carry red palm weevils (in all forms) can be imported, transported, or transported in transit, but they should also be recorded.
7 Risk Analysis Report
The risk analysis report should include a summary, background, methods, arguments, suggestions, and references. The risk analysis report should be submitted to the relevant competent authorities for review. The risk analysis report that has passed the review should be modified, or a new risk analysis should be conducted. 3

B.2.1 Significance and composition
Adaptability reflects the possibility of establishing a population in the introduction area of ​​the red palm weevil. The colonization, spread and harm of species in new areas must be based on the premise of adapting to the local climate, ecological environment, and major enemies. This criterion has three first-level indicators: adaptation to biological factors, adaptation to climatic factors, and climate suitability. B.2.2 Adaptation to biological factors
Species of plants: The number of food species directly affects the growth, development, reproduction and lifespan of individual insects, and also affects the population size and dynamics of rhinoceros beetles. If the host plants are extensive, the risk of invasion, colonization and harm caused by the red palm weevil is relatively high. Item: 21 or more host plants;
General: 6 to 20 host plants;
Rare host plants: 5 or less.
The host range is large; some species spread into a new area, may lack sufficient food sources, in this case, the species may feed on hosts that they do not feed on in their native habitat. This indicator evaluates the possibility of the expansion of the host range after the species is introduced into the risk analysis area.
The number of host plants in the origin is
Less: 1 to 3 species;
More: 4 or more species.
Risk analysis of natural enemies in the region: natural enemies in the place of origin. B.2.3 Adaptation to climatic factors
Climatic factors (including effective accumulated temperature, annual average temperature, average temperature of the coldest month, average temperature of the hottest month, maximum temperature, minimum temperature, relative humidity, light conditions, etc.) have a major impact on the wintering, summering, egg laying, hatching and other aspects of the brood, and are one of the most important factors determining the survival status of broods. To survive in a region, broods must be able to adapt to the light conditions, minimum and maximum temperatures in the region. Therefore, broods generally have the characteristics of dormancy and diapause. Summering, aestivation or summer sleep and wintering. Hibernation and winter sleep are all adaptation mechanisms of species to climate. 9This criterion layer has three first-level indicators: adaptation to biological factors, adaptation to climatic factors, and climate suitability. B.2.2 Adaptation to biological factors
Species of food: The number of species directly affects the growth, development, reproduction and lifespan of individual insects, and also affects the population size and dynamics of rhinoceros beetles. If the host plants are extensive, the risk of invasion, colonization and harm caused by red palm weevils is relatively high. Item: 21 or more host plants:
General: 6 to 20 host plants:
Minor host plants: 5 or less.
The host range is large; some species that spread into a new area may lack sufficient food sources. In this case, the species may feed on hosts that they do not feed on in their native habitat. This indicator evaluates the possibility of species expanding their range after being introduced into the risk analysis area. The number of natural enemies in the place of origin is as follows: less than 1 to 3 species; more than 4 species or more. The natural enemy situation in the risk analysis area is as follows: natural enemy situation in the place of origin. B.2.3 Adaptation to climatic factors Climate factors (including effective accumulated temperature, annual average temperature, average temperature of the coldest month, average temperature of the hottest month, maximum temperature, minimum temperature, relative humidity, light conditions, etc.) have a major impact on the wintering, summering, egg laying, hatching and other aspects of the brood. It is one of the most important factors determining the survival status of brood.
