Description

Artificial breeding method of cyrtorhinus squarrosus
Technical Field
The invention belongs to the field of plant protection and the field of insect reproduction, and particularly relates to a raising method of cyrtorhinus squarrosus.
Background
When a living organism invades into another new environment through a natural or artificial way from the original place, the process of economic loss or ecological disaster caused by biodiversity of the invaded place, production of agriculture, forestry, animal husbandry and fishery and human health is called biological invasion. The external pests enter a new ecological system, and due to the lack of restriction factors, the breeding capability and the transmission capability are strong, so that serious economic loss is caused to the field.
The coriaria sinicus belongs to the coriaria semiptera (Hemiptera) family (Tingidae), and is a coriaria sinicus with a specific host and serious harm. Nymphs and adults of the plants prick and suck plant juice on host plant leaves, and when the occurrence of the plant juice is serious, the leaves can lose green and withered yellow, the flowering period is shortened, the flower type is small or does not bloom, and even the plants die; has great harm to the growth of plants. The insect pests of the coriaria sinica are originally distributed in a new north area and a new tropical area, and nowadays, along with trade and communication between countries, corilagus sinica and corilagus versicolor invade the China sequentially. Among them, the apolygus squarrosus of the genus apolygus in 2006 invades China to date, and the apolygus squarrosus has caused serious damage to the apolygus in most 30 cities (including Shanghai and Beijing) in southwest, south China, Central China and North China. The sycamore rhynchophorus platyphylla is listed as a foreign pest with higher risk degree in China.
Since orius quadratus Corythucha marmorata (Ulher, 1878) was originally distributed mainly in the united states and south of canada, in 2002, orius quadratus invades japan and becomes a major pest of asteraceae plants represented by japanese chrysanthemum, and can damage sweet potatoes in japan, becoming an alien pest spreading rapidly in japan. In 2010, the cyrtorhinus squarrosus is recorded for the first time in Shanghai of China and becomes an invasive pest of a second cyrtorhinus of China. It was reported that, in 2011, cyrtorhinus squarrosus invades korea, and in 2013, it was found that the cyrtorhinus squarrosus spread to xixi, taiwan, and south of the river, etc. in zhejiang, the spread rate is rapid in china. Since the netus squarrosus was recorded in china, the national quarantine department has captured netus squarrosus on entry ports many times.
The compositae plant is the first major family of dicotyledonae and Chrysoideae, about 220 kinds of plants belong to 3000 kinds of China, and most of the plants have ornamental and economic values (such as oil crop sunflower, cut flower plant African chrysanthemum and chrysanthemum, economic crop chrysanthemum morifolium, Jerusalem artichoke and the like) and are widely cultivated in China. Sweet potatoes (commonly called sweet potatoes) are also important grain crops in Chinese agriculture, and the planting area is wide. If the stinkbug continues to spread the hazard in China, serious impact may be caused to the agricultural and forestry economic production of China.
In order to effectively control the damage of the cyrtorhinus squarrosus to the plants in the Compositae of China, aiming at the current situation that the cyrtorhinus squarrosus may damage the ecological safety of China and the economic production of agriculture and forestry, the artificial feeding and research of the cyrtorhinus squarrosus are urgently needed.
The existing artificial breeding method of the chinus squarrosus is to cut one yellow Canada with the plant height of 2 meters into 20cm long, keep 6-8 leaves at the upper end of each branch, wrap the lower end with sponge, fix the lower end in the center of a plastic cup and inject water to preserve moisture. Then, the branch section of the solidago canadensis is used for crawling, feeding and laying eggs of the adult solidus squarrosus in a common insect breeding cage, and the adult insects in the cage are removed after 24 hours to obtain insect eggs for later-stage breeding. Although the cost of the raised plants is low, the defect is that a large amount of manual collection, pruning and moisturizing treatment is required, and a large amount of operation time is occupied. The adult Neugo freely moves in a common insect cage and is dispersed on each leaf, and the adult female is taken out after spawning and takes much time and labor. And (3) continuously feeding the hatched stinkbug with the branch section of the solidago canadensis until adults are obtained, and frequently replacing plant feed during the period, so that large-scale feeding cannot be realized.
The length of the adult of the quadratus dipteris is 2.81mm, the width of the adult is 1.57mm, the individual is very tiny and is not easy to be found, and people who do not engage in the research are difficult to identify the adult in the field environment. The nymphs at all ages were much smaller in size and were very difficult to study by direct collection (nymphs size 0.4mm by 0.2mm to 1.56mm by 0.87 mm). In addition, after the female adult euschistosoma squarrosum enters the egg laying period, egg grains can be laid on the same blade continuously for multiple days under the natural condition, and the egg laying mode causes the incubation periods of nymphs on the same blade to be inconsistent. Therefore, after the nymphs hatch, the nymphs of 1 year old on the same day are picked by a soft brush pen for later stage separate breeding or female adults are picked by an interval of 24H to ensure that the age of the coriaria sinicus is consistent. Once the nymphs at 1 st age are very tiny and improper in operation, the nymphs can easily cause death of the nymphs; female worm dispersion need regularly collect and take out on the plant leaf, and both need use a large amount of personnel to come the separation work, have increased the cost, and also more to the demand of raising space and equipment.
Therefore, a method suitable for artificially controlling cultivation plants in the environment to be used as feed, simple and convenient for mass propagation is needed, the cyrtorhinus squarrosus can be continuously fed all the year round, and insect bodies with consistent ages are obtained to support further research, so that an effective means for preventing and controlling invasive pests is found out, ecological safety is maintained, and economic loss of agriculture and forestry is reduced.

Based on the principle, the invention provides an artificial feeding method of the adelphocoris suturalis, which comprises the following specific steps:
step S1: obtaining potted Dutch chrysanthemum with specific specifications and placing the potted Dutch chrysanthemum indoors, wherein the method specifically comprises the following steps:
step S11: preparation of culture medium and flowerpot for potted Dutch chrysanthemum: mixing vermiculite, leaf mold and garden soil at a ratio of 1:1:2, and stirring thoroughly to obtain culture medium. Before cultivation, various media of the Holland chrysanthemum need to be treated at high temperature to kill harmful organisms reserved in the medium. A plastic flowerpot with the diameter of 15-20cm is adopted, and the bottom of the flowerpot is cut into a proper size by a window screen for protection treatment, so that earthworms, horseland and the like are prevented from entering the flowerpot from the bottom during cultivation. The flowerpot is generally 5 inches and 6 inches, is one of the most commonly used sizes of common potted flowers, is easy to purchase, is moderate in size and convenient to move, and does not cause the possibility that the watering time in the seedling raising period is heavy and easy to topple due to the fact that the flowerpot is too small.
Step S12: and (3) seedling cultivation of potted Holland chrysanthemum: and (4) sowing the seeds in the cultivation media in the step S11 and respectively placing the seeds in the flowerpots in the step S11, thereby realizing the form of pot culture. And then carrying out seedling culture and cultivation on potted dutch-flower under isolation conditions to ensure that the growth process of the dutch-flower is not interfered by other factors. When it grows to 10-20 cm height and has 80-100 leaves, it can be used as breeding plant. The seedling cultivation of the Holland chrysanthemum can be carried out indoors or outdoors with isolation, and the seedling cultivation can also be carried out by using a sunlight greenhouse.
Step S13: indoor cultivation of potted Holland chrysanthemum: the Holland chrysanthemum is subjected to vegetative growth under the condition of long sunshine (above 13H of sunshine), so that the leaf area is large (see figure 1); and under the condition of short sunshine, the potted Dutch chrysanthemum is shifted to reproduction and growth, the leaf area is small (see figure 2), so after the seedling culture is finished, the potted Dutch chrysanthemum is placed indoors, the illumination period can be adjusted indoors, and the illumination period is L: d is 14: 10-L: d, 16:8, effectively controlling the growth stage of the Netherlands to be in a vegetative growth stage so as to prevent the Netherlands from being changed from the vegetative growth stage shown in figure 1 to a reproductive growth stage shown in figure 2, further improving the total leaf area of each pot of the Netherlands to obtain a plurality of pots of potted Netherlands with the height of 15-30cm and the number of leaves of 80-100 shown in figure 3, and using the pots of potted Netherlands as plant feed of Netherlands, so as to bear more Netherlands; and the long-day condition has no adverse effect on the development of the rhus squarrosus.
Step S2: inoculating a specific number of female adults of the plant bug, cyrtorhinus squarrosus, on each potted dutchmanspipe described in step S1 by a restriction device:
step S21: taking out the potted Dutch chrysanthemum of the step S1 from the rearing cage, and installing a limiting device on any plurality of leaves of each pot of the potted Dutch chrysanthemum;
step S22: a plurality of fertilized female adults of the chinus fasciatus are respectively connected to the front surfaces of the leaves in each limiting device by using a soft writing brush, so that the total number of the female adults in all the limiting devices on each potted Dutch chrysanthemum is 100;
step S23: and after the female adults feed and lay eggs in the limiting device, collecting and taking out the female adults in the limiting device after 24 hours.
Step S3: the method for feeding the euonymus squarrosus by using the potted dutchmanspipe, specifically comprises the following steps:
continuously placing the potted Holland chrysanthemum with the eggs into a rearing cage, placing the potted Holland chrysanthemum in the rearing cage indoors, and rearing the Neptunella squarrosa in an indoor rearing environment. Watering 5-inch and 6-inch pots every 3-4 days in the breeding process of the rhus squarrosus, and applying liquid fertilizer once every 21 days to ensure the normal growth of plants. Watering and fertilizing are carried out outside the rearing cage for the Holland chrysanthemum and the plant, so that the development interference on the Neugo squarrosus is reduced, and the maintenance and management time is shortened. Wherein, the indoor raising environment is: 25-30 ℃, humidity of 75% +/-5%, illumination period L: d-14: 10 (artificial lighting). The cyrtorhinus squarrosus is high-temperature resistant, the egg laying amount of female adults can be increased by properly increasing the temperature, the feeding period is favorably shortened, and the feeding efficiency is improved.
After the breeding of the Nephocoris squarrosus is finished, the late-stage cultivation can be carried out on the Dutch chrysanthemum bred with the Nephocoris squarus. After the Holland chrysanthemum is raised for one time, old stems are trimmed, the apical dominance of the plants is reduced to promote the growth of new sprout tillering plants, and the old plants are updated into new plants suitable for raising through horticultural management measures (such as plant division or pot division cultivation). The sprout tillering capacity of the Holland chrysanthemum is strong (3-10 buds), and enough new strains can be obtained to be used as subsequent feed plants. Because the indoor artificial environmental conditions are constant, the lotus chrysanthemum can be cultivated in four seasons. The separated or potted Dutch chrysanthemum is generally used again after 50-60 days.

According to the method, a certain number of female adults are inoculated through the limiting device to lay eggs in the potted Dutch chrysanthemum, the eggs laid on the same day are obtained every day, and the hatching and development time of the Neptunes squarrosus in the same pot is relatively consistent, so that eggs with the same age of day or other insect states can be obtained as required, the requirement of the development progress of the Neptunes squarrosus is met, and the method is convenient for further scientific research; in addition, the fertilized female adults are placed in a limiting device to lay eggs, so that the total egg laying amount of the female insects on each pot of the Holland chrysanthemum can be controlled, counting is facilitated, the egg laying amount (for example, 100 eggs per pot) of the Holland chrysanthemum female insects is controlled, and nutrition required by the development of the Nephoid squarris from nymphs to adults is ensured.
Effects of the invention
Indoor, the development progress of the dictyotis squarrosus raised on the netherlands was as follows: hatching egg granules for 7-9 days, 2 days for 1-year nymph, 2-3 days for 2-year nymph, 3-4 days for 3-year nymph, 5-6 days for 4-year nymph, 6-7 days for 5-year nymph, and 1-2 days for eclosion period; after 26-33 days, the eulygus quadratus adults which grow regularly can be obtained, or nymphae of the required age can be obtained. As shown in figure 4, 5-year-old nymphs of 35 Nepeta squarrosus on one Dutch chrysanthemum leaf in the rearing cage are consistent in development progress. Because the artificial breeding is carried out in the indoor breeding environment, the indoor environment is controllable, the illumination, the temperature and the humidity can be controlled manually, and the cyrtorhinus squarrosus can be bred continuously all the year round. After 2 years of practice, a large amount of adult and nymphaea fruticosa for carrying out related scientific experiments can be obtained according to the breeding method.
