Example Embodiment

[0016] Example 1

[0017] A method for synergistic control of rice borer by combined application of bees and fungi, comprising the following operations:

[0018] S1. Systematically monitor the laying of eggs of the adults of Dichilla borer. The first bees are released 3 days after the eggs begin to appear. There are 3 bee placement sites per mu, with 4,000 Trichogramma per site, including 400 Trichogramma rice borers. 3,000 Trichogramma pine caterpillars and 600 Trichogramma borers, which are made into bee cards or put in bee traps in paddy fields; Trichogramma should be released on cloudy or rainless evenings to avoid rain and sunlight exposure , or contact with toxic substances.

[0019] S3. The second bee release is carried out at an interval of 5-7 days, and the bee release method and bee release amount are the same as the first time;

[0020] S4, 2-3 days after the second bee release, spray 50 billion / g Beauveria bassiana wettable powder with a dose of 250g / mu evenly on...

[0023] A method for synergistic control of rice borer by combined application of bees and fungi, comprising the following operations:

[0024] S1. Systematically monitor the laying of the eggs of the adults of Diplodocus chinensis. Bees are released for the first time 3 days after the eggs start to appear. There are 3 bee placement sites per mu, with 3,000 Trichogramma per site, including 500 Trichogramma rice borers. , 2,000 Trichogramma pine caterpillars, and 500 Trichogramma borers, which are made into bee cards or put in a bee trap in the paddy field; Trichogramma should be released on cloudy or rainless evenings to avoid rain and sunlight. Exposure to sunlight, or contact with toxic substances.

[0025] S3. The second bee release is carried out at an interval of 5-7 days, and the bee release method and bee release amount are the same as the first time;

Abstract

The invention discloses a method of coordinatively controlling Chilo suppressalis by combined use of bees and fungi. Systematic monitoring is provided for adults of Chilo suppressalis to lay eggs; bees are released for the first time 3 days after the early stage of egg occurrence; bees are released for the second time 5-7 days later; Beauveria are sprayed 2-3 days after the second release of the bees and are sprayed again 5-7 days later; the effect to control Chilo suppressalis reaches 90% and above. By releasing Trichogramma to host on Chilo suppressalis and spraying Beauveria to kill larvaeof Chilo suppressalis and using bee-fungus coordinative damage control, the biological control effect for Chilo suppressalis is improved, and technical guarantee is provided for pollution-free rice production.

Description

technical field [0001] The invention relates to the field of biological control, in particular to a method for synergistically controlling rice stem borer by combined application of bee fungus. Background technique [0002] Rice stem borer Chilo suppressalis (Walker), commonly known as core borer, stalk borer, white ear worm, etc., belongs to the genus Chilo Zinchin of the family Pyralidae in the order Lepidoptera, and is the most important species in rice production. The common pests of rice can directly cause dead hearts and white ears by boring rice stems. Damage caused by insect damage to plants during the filling period can lead to insufficient grains, resulting in a decrease in yield and quality, and boring rice plants will lead to lodging resistance after eating empty pith cavities, resulting in more serious indirect losses. In general years, it can cause 10% yield loss, and in severe cases, it can reach more than 50%. In recent years, due to changes in climate, far...
