Problems solved by technology

[0004] At present, the main dosage forms of Beauveria bassiana for controlling pests are powder, oil and wettable powder, etc. There are still disadvantages in the control of pests such as single dosage form, low labor efficiency, and slow insecticidal speed.

Embodiment 1

[0043] In this embodiment, taking corn borer as the target borer as an example, the method for preventing and controlling borer pests provided in this embodiment is introduced.

[0044] The method for preventing and treating stem borer pest that the present embodiment provides comprises:

[0045] (1) Trichogramma ovum and Trichogramma ovum (ratio is 14:1) and the ratio of 0.2g Beauveria bassiana spore powder that Trichogramma ovum and Trichogramma ovum (ratio is 14:1) and 0.2g Beauveria bassiana spore powder will be Trichogramma ovum and Beauveria bassiana spore powder mixed;

[0046] (2) The above mixture is released to the corn field, the number of times: twice; the bee release time: the first release time is at the initial stage of corn borer spawning, and the second release is performed at an interval of 5-7 days.

[0047] (3) Bee release method: the mixture of Trichogramma eggs and Beauveria bassiana spore powder is placed in the bee release container (a spherical double...

[0049] The control effect of the method for the control borer pest of verification embodiment 1

[0050] 1. Experimental Design

[0051] Treatment 1: blank control, without Trichogramma and Beauveria bassiana;

[0052] Process 2: Use Beauveria bassiana spore powder (purchased from Jilin Provincial Agricultural Institute Biological Preparations Experimental Factory) alone; Consumption is 0.2g Beauveria bassiana spore powder per hectare; Conidia content in every g Beauveria bassiana spore powder 1×10 12 indivual;

[0053] Treatment 3: use Trichogramma alone (every release total of 15,000 Trichogramma pine caterpillar eggs and Trichogramma melanogaster eggs per hectare, the ratio of bee eggs is 14:1, and the bee eggs are provided by the applicant Gongzhuling Jinong Green Produced by Agricultural High-tech Development Co., Ltd.);

[0054] Process 4: press the method for embodiment 1, use bacterium-carrying Trichogramma (every release total number is 15000 per hectare Trichogra...

Embodiment 2

[0067] In this example, rice stem borer is taken as the target stem borer as an example, and the method for preventing and controlling borer pests provided in this example is introduced.

[0068] The method for preventing and treating stem borer pest that present embodiment provides, comprises:

[0069] (1) Release a total of 12,000 caterpillar Trichogramma eggs, Trichogramma japonica eggs and Trichogramma rice borer eggs (in the order of 8:3:1) and 0.2 g of Beauveria bassiana spores per hectare each time Mix the Trichogramma egg with the Beauveria bassiana spore powder;

[0070] (2) The above-mentioned mixture is released to the paddy field, the number of releases of bees: three times; the time of discharge of bees: the peak period of the first release time of rice stem borer moths, after that, the second release and the third release are performed at intervals of 5 days. freed.

[0071] (3) Bee release method: the mixture of Trichogramma eggs and Beauveria bassiana spore p...

Abstract

The invention discloses a method for preventing and controlling damage of stem borers and relates to the technical field of biological prevention and control of the damage of the stem borers. The method for preventing and controlling damage of the stem borers comprises the following step: releasing a mixture of trichogramma eggs and beauveria spore powder to a target prevention and control area soas to prevent and control target stem borers, wherein the target stem borers are european corn borers or rice stem borers; the mixture released to the target prevention and control area every time per hectare contains 12000-15000 trichogramma eggs and 0.18-0.2g of beauveria spore powder. The method disclosed by the invention has the beneficial effects that by control for the proportion of the trichogramma eggs and the beauveria spore powder, the damage of the stem borers can be effectively controlled, and the use times and the use amount of pesticide and beauveria can be reduced, so that notonly is the labor intensity of farmers reduced, but also the prevention and control cost is reduced, the effects of increasing the yield and the income of the farmers and improving the quality of agricultural products are realized, and the ecological, social and economic benefits are good.

Description

technical field [0001] The invention relates to the technical field of biological control of borer pests, in particular to a method for controlling borer pests. Background technique [0002] Trichogrammatid is a parasitic insect belonging to the family Trichogrammatidae of the order Hymenoptera. It relies on the olfactory organs on its antennae to find its host. First touch the host with the tentacles, linger for a while and climb on it, and use the ovipositor at the end of the abdomen to drill into the host body and lay eggs in it. Larvae parasitize moth eggs and are therefore used for biological control. Among the control targets are Lepidoptera, Diptera, Coleoptera, Hymenoptera, Wideoptera, Neuroptera, Homoptera and other 7 orders, 44 families, 203 genera, and more than 400 species. Among them, Lepidoptera insects are the most, accounting for 28 families. Trichogramma japonicun hosts 37 species, and it is the dominant species that hosts the eggs of rice pests in south...
