Embodiment

[0027] A method for monitoring and evaluating insect communities in tobacco fields after large-scale release of Aphids persicae, comprising the following steps:

[0028] 1) Determine the scope and sample plants of tobacco field monitoring:

[0029] a. Random sampling: In the smoking area where the Aphidius sylvestris was released, before random sampling, divide and label the sample plots of the whole population, randomly select 4 tobacco fields, and sample at five points in each tobacco field, with an interval of at least 100 meters between the points , investigate 4 continuous tobacco plants on a ridge planting row at each point;

[0030] b. Sampling selection: In the tobacco area where Aphidius sylvestris was released, select a representative 100 mu contiguous planting area, and set up a Male's insect trap in the middle of the tobacco field. The wind direction is set in parallel.

[0031] An important link in taxonomic work is to collect enough series of specimens (samples...

Abstract

The invention relates to an inset community monitoring evaluation method for a tobacco field after aphidius gifuensis ashmead is released in a large scale and belongs to the field of tobacco field ecology. The method includes the following steps of 1, determining a monitoring range and sample plants of the tobacco field by means of a random sampling method and a sample selection method; 2, according to direct and indirect influence relations between aphidius gifuensis ashmead and insets of the tobacco field, determining monitored objects; 3, according to the growth of tobacco plants and growthconditions of the insets, determining a monitoring method and monitoring time; 4, conducting monitoring evaluation, wherein according to monitoring indexes, a multi-index evaluation method is adoptedfor evaluation and analysis of the inset community of the tobacco field after aphidius gifuensis ashmead is released. The occurrence rate of myzus persicae in the tobacco field can be obtained, the density of the natural enemies of myzus persicae can be obtained, the density of main pests and the data indicating the diversity of the inset community can also be obtained, the ecological effect of aphidius gifuensis ashmead which is released in the large scale within an application area is determined, and bases are provided for further improving the application of aphidius gifuensis ashmead.

Description

technical field [0001] The invention belongs to the field of tobacco field ecology, and in particular relates to a method for monitoring and evaluating insect communities in tobacco fields after large-scale release of Aphids persicae. Background technique [0002] In recent years, Yunnan Province has vigorously carried out the technical research and application of the biological control of aphids on tobacco by Aphids persicae. Since the implementation of the biological control technology of C. 85% of the smoke area, the control effect is 80%-92%, and the use of pesticides is reduced by more than 60%. Yuan. This technology has also radiated and driven crops such as rapeseed, vegetables and fruit trees to carry out biological control of aphids, and the application area has reached 11.2089 million mu. The parasitism rate of Aphids persicae on peach aphids, radish aphids and rape aphids has reached more than 80%, reducing the use of pesticides More than 40%. Practice has succ...
