Embodiment 1

[0054] Embodiment 1 Morphological characteristics and living habits of A. chinensis

[0055] 1. The morphological characteristics of the chrysoplasty:

[0056] [Adult] The whole body is painted black, and there is a "U"-shaped yellow stripe on each elytra. The body length of the female adult is 7.0mm, and that of the male adult is 5.7mm. Antennae whip-like, 11 segments, 1 / 3 of body length. The ventral surface of the female is flat, and the two abdominal segments at the end are exposed outside the elytra; the abdomen of the male is covered by the elytra, and an external genitalia is hidden in an oval recess at the end of the ventral surface.

[0057] [Eggs] Pale yellow, long cylindrical shape, 1.25mm long, 0.38mm wide, formed into egg masses, about 12-54 eggs per piece, 32 eggs on average. Arrange two columns in the shape of "eight".

[0058] [Larvae] The larvae are 3 instars in length and cylindrical in shape. The widths of their heads and shells are 0.25mm, 0.50mm, and 0....

Embodiment 2

[0080] The non-winter season artificial large-scale raising of embodiment Erliancao Anthosteraster

[0081] (1) The basic facilities for the non-winter season of A. chinensis

[0082] The support of the greenhouse can be built with steel pipes, wood, bamboo or cement, and the size can be designed and constructed according to the terrain. The size of the standard greenhouse is 8m×30m (240m 2 ); the top is covered with plastic film for heat preservation and moisture retention, and 30-40 mesh insect-proof nets are used on the side to improve the ventilation effect ( figure 1A). The soil type is not limited, the fertilizer is moderate, and it has a certain degree of porosity and good water retention performance. The greenhouse is divided into 2 columns longitudinally, with a 1m-wide channel left in the middle; multiple soil beds with a height of about 5-8 cm are horizontally formed on each side, and the distance between the soil beds is 50-60 cm. Where conditions permit, a spri...

Embodiment 3

[0101] The artificial large-scale raising of winter of embodiment Sanliancao Asteroptera

[0102] (1) Basic facilities for winter rearing of A. chinensis

[0103] The winter feeding room is mainly used for raising A. chinensis in winter (from late November to early March of the following year). The area depends on the scale of breeding, usually 3 rooms are needed, which are used as clean seedling room, adult oviposition room and larvae rearing room respectively. 10-20m per room 2 , Indoor temperature adjustment adopts air conditioner or oil heater, humidity adjustment adopts air humidifier, and exhaust fan is installed for ventilation.

[0104] In the breeding room in winter, set up several insect racks with a size of 150cm×50cm×195cm. The insect racks are made of metal angle steel. Each insect rack is divided into 2 layers, and the bottom is padded with thicker glass. The board is used to store potted seedlings, and 6 fluorescent lamps with a specification of 36W are insta...

Abstract

Thee invention relates to the field of biological control, in particular to an artificial mass raising method for agasicles hygrophila. The non-winter artificial mass raising method for the agasicles hygrophila includes the following steps: (1) alternanthera philoxeroides is grown in a greenhouse; (2) when the alternanthera philoxeroides plants are as high as 15cm to 20cm and the stem diameter reaches more than 2.6cm, the agasicles hygrophila is evenly released into the greenhouse according to the density of 10 to 20 adults per square meter; (3) spray irrigation is carried out for one to two times each day, 15 to 20 minutes each time; (4) every 5 to 7 days, the density of the agasicles hygrophila in the greenhouse is surveyed, and dynamic population monitoring is carried out; (5) after the agasicles hygrophila is released for 40 to 60 days, when the number of the adults is notably increased, the adults are collected and stored. The artificial mass raising technique for the agasicles hygrophila is simple, and is easy to master, the raising cost is low, and after being released into the field to control the alternanthera philoxeroides, the agasicles hygrophila can bring enormous economic, social and ecological benefits.

Description

technical field [0001] The invention relates to the field of biological control, in particular, the invention relates to an artificial large-scale breeding method of A. chinensis. Background technique [0002] Alternanthera philoxeroides, belonging to the family Amaranthaceae and the genus Alternanthera, originated in Brazil, Uruguay, Argentina and other countries in South America. It is a perennial herb that reproduces asexually by producing adventitious roots through stem nodes. vicious weed. In our country, A. japonicus was introduced into the Yangtze River Basin and southern provinces as a feed plant in the 1950s, and became wild in the late 1980s. At present, it is widely distributed in 18 provinces and cities including Hunan, Hubei, Sichuan, Chongqing, and Fujian. The occurrence area in the middle and lower reaches of the Yangtze River is wide and the degree of harm is high. A. chinensis can form different biotypes (aquatic and terrestrial) in different habitats, and...
