Embodiment 1

[0020] 1. In late April 2019, the five-point investigation method was used to investigate the density of larvae and egg masses of Lepidoptera pests such as gypsy moth, green scorpion moth, fall moth, borer and other lepidopteran pests in 100 mu of grass and fruit forest in Fugong County, Nujiang Prefecture, Yunnan Province. .

[0021] 2. At the beginning of May 2019, put the 2nd instar nymphs of the genus Pronghorn stinkbug into a paper cup at a density of 18 heads / cup, put a lining cardboard inside, cover the cup and poke holes in the lid for ventilation.

[0022] 3. After packing, transport the paper cups to the pre-release grass fruit field in the morning, and place 5 cups per mu in scattered spots in the grass fruit bushes before ten o'clock. Just bevel. After the release, the pest density was investigated, and the overall decrease rate of the lepidopteran pest density was 88.1% within 15 days. Compared with the blank control, the control rate reached 68.5%.

Embodiment 2

[0027] 1. In late April 2019, the five-point investigation method was used to investigate the density of larvae and egg masses of Lepidoptera pests such as gypsy moth, green scorpion moth, spodopteryx moth, borer and other lepidopteran pests in 50 mu of grass and fruit forests in Lushui City, Nujiang Prefecture, Yunnan Province. .

[0028] 2. At the beginning of May 2019, put the 2nd instar nymphs of the genus Pronghorn stinkbug into a paper cup at a density of 15 per cup, put a lining cardboard inside, cover the cup and poke holes in the lid for ventilation.

[0029] 3. After packing, transport the paper cups to the pre-release grass fruit field in the morning, and place 5 cups per mu in scattered spots in the grass fruit bushes before ten o'clock. Just bevel. After the release, the pest density was investigated, and the overall decrease rate of the lepidopteran pest density was 90.8% within 15 days. Compared with the blank control, the control rate reached 70.5%.

Abstract

The invention relates to the technical field of biological control in production of traditional Chinese medicinal materials, in particular to a method for controlling Lepidoptera pests of Amomum tsao-ko by using natural enemies. According to the method for controlling the Lepidoptera pests of the amomum tsao-ko by using the natural enemies, the control natural enemies adopts cantheconidea furcellata, the cantheconidea furcellata is put twice every year, the appropriate time for the first-time putting is from late April to early May, the appropriate time for the second-time putting is from late June to late July, and the cantheconidea furcellata is released before ten o'clock in the morning and after five o'clock in the evening in cloudy days or sunny days. The release density of the cantheconidea furcellata is 30-100 / mu, and the release method is a scatter release method. According to the particularity of an amomum tsao-ko planting area, organic and ecological food is an inevitable trend of modern food production and development, and lepidoptera pests are the most important pests of amomum tsao-ko; by comprehensively considering the above aspects, the method for controlling the Lepidoptera pests of the Amomum tsao-ko by using the natural enemies is provided, which is ecological and safe and can reduce the damage of the Lepidoptera pests of the Amomum tsao-ko to be below a control threshold of the Amomum tsao-Ko economy.

Description

technical field [0001] The invention relates to the technical field of biological control in the production of traditional Chinese medicinal materials, in particular to a method for using natural enemies to prevent and control the Lepidoptera pests of Tsagocarpus. Background technique [0002] Amomum tsao-ko Crevost et Lemaire is a perennial herb of the genus Cardamom in the Zingiberaceae family. It grows in tropical and subtropical shaded and humid forests at an altitude of 1100-1800 meters, and is mainly distributed in Yunnan, Guangxi, Guizhou and other places. Its dried ripe fruit is used as medicine. It has the effects of drying dampness and warming the middle, eliminating phlegm and intercepting malaria. At the same time, Caoguo belongs to medicinal and edible medicinal materials, and it is widely used as a flavoring raw material for food in the folk, and its whole plant (generally the fruit is the most) contains 1,8-cineole, trans-2-decenal , Citral-b and other aromat...
