Problems solved by technology

According to the analysis of existing experience, Trichogramma should have great potential in resisting the sunflower borer, but in the published literature on the control of the sunflower borer, no information about the dominant bee species of the sunflower borer, the bee release period, and the bee release period have been found. A complete and systematic research report on key issues such as quantity

[0031] Population Dynamics Analysis Experiment of Sunflower Borer Adults

[0032] 1. Test site

[0033] The test site is located in the test site of the Sunflower Research Institute in Gannan County, where sunflowers are planted all year round, and the population base of sunflower borers is large, which is convenient for trapping with sex attractants and data analysis.

[0034] 2. Experimental design

[0035] The dynamics of adult populations in the field were monitored using sex attractants produced by Beijing Zhongjie Sifang Biotechnology Co., Ltd. The lure is a green rubber stopper in the shape of an anti-mouth half bell. During use, add water to 80% of the common white plastic basin with a basin mouth diameter of 30 centimeters and a depth of 10 centimeters. Then the lure core is threaded and suspended above the center of the water surface with thin iron wire, 1.5 centimeters away from the water surface to make a trap. The water basin is 1.5 meters above the ground. A...

[0068] Trichogramma

[0069] Collect different geographical strains of Trichogramma pine caterpillar in Baiquan, Gannan, Lindian, and Yi'an, Heilongjiang, and collect them from sunflower borer eggs in sunflower fields. The sunflower borer eggs collected in the field and parasitized by the Trichogramma pine caterpillar were cultivated in a light incubator at 25° C. and RH80%-85%. Inoculate bee species on tussah eggs, purify, multiply, and participate in the experiment (Table 4).

Abstract

The invention discloses an experimental method for using trichogramma to prevent and control sunflower stem borers and an implementation scheme of the experimental method. The experimental method includes dynamic analysis experiments of adult population of the sunflower stem borers, screening of trichogramma species and good strains, screening of advantageous trichogramma dendrolimi good strains and control effect comparison experiments on preventing and controlling the sunflower stem borers in a beekeeping period. The implementation scheme acquired through the experimental method includes variety selection of trichogramma, making of bee cards, and determining of the number of beekeeping, beekeeping quantity, beekeeping time, beekeeping method and beekeeping environment requirements. The experimental method and the implementation scheme thereof have the advantages that the designed technical scheme reaches the domestic advanced level, and considerable economic benefit and obvious ecological benefit are obtained.

Description

technical field [0001] The invention relates to a test method for controlling the sunflower borer with Trichogramma, and also relates to an embodiment obtained by the test method. Background technique [0002] Sunflower seeds are not only attractive in aroma, but also rich in a large amount of unsaturated fatty acids, vitamins and trace elements. They are a popular snack food and edible oil raw material. Although the cultivation of sunflowers in China was very extensive in history, in recent years, due to reasons such as climate and repeated cropping, the occurrence of insect pests has continued to increase, resulting in the shrinking of the sunflower planting area year by year. Taking Gannan County, Heilongjiang Province, which is known as the home of sunflowers in China, as an example, the sunflower planting area has shrunk from 900,000 mu in 2003 to more than 120,000 mu in 2012. [0003] Sunflower pests are mainly caused by the sunflower borer, which damages sunflower fl...
