Problems solved by technology

[0004] At present, there is no systematic research on the indoor breeding of japonica japonica, most of which are mainly collecting field japonica japonica, and raising them indoors for short-term completion of experiments, lack of long-term and stable indoor breeding of japonica japonica Ladybugs are studied, and there is no stable source of indoor insects, resulting in the artificial mass propagation and release of the Japanese ladybug. Therefore, it is urgent to establish a method for indoor large-scale breeding of the Japanese ladybug
[0005] However, in the process of indoor reproduction of M. japonicus, the collection of pupae is an important obstacle restricting the artificial large-scale reproduction of M. japonicus, because the mature larvae of M. japonicus like to cluster on the back of old leaves, plastic Pupation occurs in the grooves on the edge of pots or in other hidden corners of the insect culture room, which are relatively scattered and difficult to find and collect
At present, there is no effective method for collecting the pupae of S. japonicus, so it is impossible to achieve large-scale indoor breeding of S. japonicus

Embodiment 1

[0043] Embodiment 1: the collection method of Japanese ladybug pupae

[0044] 1, step a ladybug ovum obtains: the eggplant plant that has been infected with Bemisia tabaci is moved into ladybug adult raising cage (the conventional insect cage that adopts nylon gauze to make, wide 40cm * deep 45cm * high 50cm), during the oviposition period ladybug Female adults will automatically lay eggs on the back of eggplant leaves; by replacing eggplant plants infected with whitefly every day, you can continuously obtain ladybug eggs with relatively uniform development status.

[0045] 2. Ladybug juvenile rearing in step b: move the potted eggplant plants with ladybug eggs produced in step a into the ladybug breeding room and raise them for 14-15 days;

[0046] 3. Collection of ladybug pupae: when the young ladybug (egg stage + larval stage) grows to the 12th day, place a pupation circle at the base of the eggplant stem; when the young ladybug (egg stage + larvae stage) grows to the 14th ...

Embodiment 2

[0050] Example 2: Evaluation of the collection effect of the pupation circle on the pupae of the Japanese ladybird beetle

[0051] Mature larvae of the Japanese ladybug prefer to pupate on the back of old leaves, in the grooves of the edge of plastic pots, or in other hidden corners of the insect culture room. They are relatively scattered and difficult to collect collectively. Improving the collection efficiency of ladybug pupae is of great significance to improving the reproductive efficiency.

[0052] 1. Use single-sided corrugated cardboard as the material to make a ladybug pupation ring.

[0053] First, cut the single-sided corrugated cardboard into long strips of corrugated cardboard (such as figure 2 ), the length is 45cm, and the width is designed to be 3.0cm, 4.0cm, 5.0cm, 6.0cm, 7.0cm respectively. Wrap 3 circles along the base of the stem of the potted eggplant plant, and fix it into a cylindrical pupation circle with pins (such as image 3 ), the corresponding ...

Embodiment 3

[0059] Embodiment 3: method for artificial large-scale propagation of ladybug japonica

[0060] The artificial large-scale breeding of Japanese ladybug uses eggplant as the host plant for breeding Bemisia tabaci, and uses whitefly as the prey for raising Bemisia tabaci, involving eggplant plant cultivation, prey Bemisia tabaci breeding, ladybug eggs Collection, feeding of ladybug larvae, collection of ladybug pupae and rearing of ladybug adults.

[0061] 1. Eggplant plant cultivation

[0062] (1) buy the matrix nutrient soil that is used for raising seedlings in the market, then put nutrient soil into the prepared seedling-raising tray of 58cm * wide 30cm for subsequent use;

[0063] (2) Use eggplant as the host plant for breeding Bemisia tabaci, buy eggplant seeds susceptible to bemisia tabaci in the market, soak 30 minutes with 0.1% carbendazim solution of active ingredient before sowing, then, put the seeds on wet gauze Wrap it in the middle, place it under the condition ...

Abstract

The invention provides a method for collecting pupae of Serangium japonicum Chapin. The method includes the steps of obtaining eggs of the Serangium japonicum Chapin, feeding young Serangium japonicum Chapin, collecting the pupae of the Serangium japonicum Chapin and the like. Compared with the prior art, the method for collecting the pupae of the Serangium japonicum Chapin has the advantages that the eggs of the Serangium japonicum Chapin, relative consistent in development conditions, can be obtained continuously, single-faced corrugated boards easily available to raw materials are made into pupating rings easily and conveniently, and accordingly collection of the pupae is facilitated; rapid efficient large-batch reproduction of the Serangium japonicum Chapin is achieved, and the method is scientific, reasonable, simple to operate, convenient and practical.

Description

technical field [0001] The invention belongs to the field of insect reproduction, and in particular relates to a method for collecting pupae of the japonica beetle and a method for artificial large-scale propagation of the japonica beetle. Background technique [0002] The reproduction and utilization of natural enemy insects is an important means of sustainable ecological management of pests. The use of indoor large-scale breeding of natural enemy insects for commercial production and application is to replace and reduce the use of chemical pesticides, protect the environment, protect biodiversity, increase the output of agricultural products and One of the main ways of quality. [0003] Ladybug japonica is an important local predatory natural enemy of whitefly. It can prey on whitefly eggs, nymphs of all ages, and adults of whitefly, and adult ladybugs are fond of whitefly eggs, so it can effectively control The increase in the population of Bemisia tabaci is also conduci...
