Embodiment 1

[0026] A method for biologically controlling Spodoptera frugiperda by utilizing stink bugs, the specific steps are as follows:

[0027] (1) The occurrence of fall armyworm was monitored throughout the year in the scattered area, and no fall armyworm was detected;

[0028] (2) Before the stinkbugs were scattered, a general survey was carried out on the population of Spodoptera frugiperda in the scattered area, and no harm of Spodoptera frugiperda was found;

[0029] (3) Carry out preventive dispersal, disperse stinkbugs at a rate of 20 heads / mu, and each dispersal point is randomly distributed;

[0030] (4) After the stinkbugs were scattered, the harm of fall armyworm was still not detected;

[0031] (5) According to the data of insect tracking, chemical control means are not required.

Embodiment 2

[0033] A method for biologically controlling Spodoptera frugiperda by utilizing stink bugs, the specific steps are as follows:

[0034] (1) Monitor the occurrence of fall armyworm in scattered areas throughout the year, and detect fall armyworm;

[0035] (2) Before the stinkbugs were scattered, a general survey was carried out on the population of Spodoptera frugiperda in the scattered area, and it was found that the damage of Spodoptera frugiperda was 0.1 head / plant;

[0036] (3) Carry out therapeutic dispersal, 50 stinkbugs per mu, and each dispersal point is close to the harm area of ​​Spodoptera frugiperda;

[0037] (4) After releasing the stinkbug, continue to monitor the harm of the fall armyworm;

[0038] (5) According to the data of insect tracking, the control effect is more than 80%, and no chemical control method is needed.

Embodiment 3

[0040] A method for biologically controlling Spodoptera frugiperda by utilizing stink bugs, the specific steps are as follows:

[0041] (1) Monitor the occurrence of fall armyworm in scattered areas throughout the year, and detect fall armyworm;

[0042] (2) Before the stinkbugs were scattered, a general survey was carried out on the population of Spodoptera frugiperda in the scattered area, and it was found that the damage of Spodoptera frugiperda was 0.15 head / plant;

[0043] (3) Carry out therapeutic dispersal, 50 stinkbugs per mu, and each dispersal point is close to the harm area of ​​Spodoptera frugiperda;

[0044] (4) After releasing the stinkbug, continue to monitor the harm of the fall armyworm;

[0045] (5) According to the data of insect tracking, if the control effect is less than 80%, chemical control measures should be adopted.

Abstract

Arma chinensis, as an important predatory natural enemy, has a good control effect on many lepidopteran and coleopteran pests. The invention provides a method for biologically preventing and treatinggrassland spodoptera frugiperda by the arma chinensis. The method includes the following steps: (1) monitoring a free-range breeding area, (2) performing general survey on the free-range breeding area, (3) breeding the arma chinensis in a free range, (4) tracking pest conditions, and (5) providing supporting plans. The method can control the grassland spodoptera frugiperda through biological prevention and treatment means of 'treating pests by insects', the control effect is more than 80%, the pesticide consumption is reduced, and social and ecological benefits are good.

Description

technical field [0001] The invention relates to the technical field of biological control, in particular to a method for biological control of Spodoptera frugiperda by using the natural enemy insect stinkbug. Background technique [0002] Foliage Moth, Spodoptera frugiperda (Smith), also known as fall armyworm, belongs to Lepidoptera Lepidoptera, Noctuidae family Noctuidae, is native to tropical and subtropical regions of the Americas, is a major transboundary migratory agricultural pest for global warning by the Food and Agriculture Organization of the United Nations, and is widely harmful Corn, tobacco, potato, rice, cotton, sorghum, alfalfa, barley, buckwheat, oats, millet, peanut, ryegrass, sugar beet, sudangrass, soybean, tomato, onion, wheat and more than 80 kinds of plants. In 2016, fall armyworm was first discovered in Nigeria, Africa, and invaded 44 countries in Africa within two years. From May to mid-December 2018, fall armyworms successively invaded India, Bang...
