Embodiment 1

[0037] Embodiment 1: as attached figure 1 , 2 As shown, the method for predicting the control period of Populus euphratica inchworm control period based on the relationship between insect state development and temperature includes the following steps:

[0038]The first step is to obtain the data source used in the research; the Populus euphratica forest information is extracted through optical satellites, and the Populus euphratica forest information includes temperature information, remote sensing satellite image information and basic geographic information data, and then enter the second step;

[0039] The second step is to extract the spatial distribution information of Populus euphratica forest; the object-oriented method is used to classify the remote sensing images, and the spectral characteristics are used as the threshold range for extracting the distribution information of Populus euphratica to obtain the main growth area of ​​Populus euphratica forest, and then enter...

Embodiment 2

[0056] Embodiment 2: as attached Figures 3 to 13 As shown in Tables 1 to 5, the active period of Populus euphratica includes the eclosion of pupae, the reproduction process of adults, the hatching of eggs and the growth and development process of larvae. The pupae of Populus euphratica is in a dormant state during the dormancy period underground, so it is not included in the active period. According to statistics, the active period of Populus euphratica is mainly in February, March, April and May each year. The growth and development process of the active period, plus the dormancy period in summer, autumn and winter, constitutes a complete generation cycle. The present invention studies on the occurrence of the populus euphratica, focusing on the exploration of the development process of each insect state during the activity period of the populus euphratica. The main factors affecting the development process of insects are: food and temperature. And in the metamorphosis dev...

Abstract

The invention relates to the technical field of forest data remote sensing analysis, in particular to a populus euphratica apocheima cinerarius prevention and cure period prediction method based on the relationship between insect-state development and temperature, which comprises the following steps: step 1, acquiring a data resource; step 2, extracting the space distribution information of a populus euphratica forest; step 3, extracting temperature information; step 4, judging the accuracy of the remote sensing temperature, step 5, establishing an analysis model of temperature variation characteristics of the active stage of the populus euphratica apocheima cinerariuses; step 6, establishing an analysis model of the characteristics of insects in various stages of the populus euphratica apocheima cinerariuses; step 7; establishing an analysis mode of the survival rate and the temperature change of each change form of the populus euphratica apocheima cinerariuses; step 8, calculating the development rate of each insect state of the Populus euphratica apocheima cinerariuses; step 9, judging the best prevention and cure period of the populus euphratica apocheima cinerariuses. Throughthe modeling analysis, the prevention and cure are carried out in the second-instar period, the best prevention and cure period is found, and the pests and diseases can be effectively eliminated, which is of great significance for promoting the normal growth of the populus euphraticas.

Description

technical field [0001] The invention relates to the technical field of forestry disease and insect pest control period prediction, and relates to a method for predicting the control period of Populus euphratica spring inchworm based on the relationship between insect state development and temperature. Background technique [0002] The Yarkand River Basin is located in the south of Xinjiang. It is the most concentrated area of ​​Populus euphratica forests in the world, and it is also the area with the weakest ecological balance. The area of ​​Populus euphratica forests is about 190,000 hectares of forest land and about 1 million hectares of sparse forest land. They are mainly distributed along desert rivers and on the edge of deserts. The zone is the main vegetation type in the plain desert ecosystem, and it is also the skeleton of the natural oasis ecosystem and the outer barrier of the artificial oasis. In addition, the Yarkand River Basin is one of the main sources of dust...
