Technical Field
The invention belongs to the technical field of insects, and particularly relates to a method for improving the feeding effect of arma bug by adding a substitute host plant.
Background
Arma chinensis can prey on eggs, larvae and adults of more than 40 kinds of agricultural and forestry pests, has a good control effect on invasive pests such as potato beetles, fall webworms, spodoptera frugiperda and the like, and is an important local natural enemy insect. With the enhancement of environmental awareness of people, a method for controlling agricultural and forestry pests by using natural enemy insects is gradually taken into consideration by people.
For a long time, people add poplar, elm branches and leaves and soybean seedlings as host plants in the lugworm breeding process to increase the moving range of the lugworm, reduce the self-disability of the lugworm and improve the adult yield of the lugworm. Poplar and elm branch and leaf can not be cultivated in the laboratory, the use is limited by seasons, the poplar and elm branch and leaf need to be frequently replaced, and the labor cost of the arma bug production is increased; although the soybean seedlings which can be cultivated in the greenhouse can replace poplar trees and elm branches and leaves to be used as host plants for arma bug breeding, the soybean seedlings are easy to wither and stink, and the problem of large arma bug breeding environment cleanness is brought. How to reduce the self-disabled condition of the arma chinensis in the feeding process, reduce the labor and economic investment in the feeding process, and improve the feeding effect of the arma chinensis is a problem worthy of attention.

Further, the method for cultivating the host plant comprises the following steps: planting host plants by using a planting pot and vermiculite, cutting the host plants when the host plants grow to 10-15cm, airing the liquid at the cut openings of the plants for 15-20min in a ventilated environment, and temporarily culturing the host plants in clear water for later use; when the cultivation method is used, the base of the host plant is wrapped by absorbent cotton, the host plant is added into the cultivation space, and the arma chinensis is inoculated into the cultivation space.
The beneficial effect of adopting the further scheme is that: the absorbent cotton is soaked by water, so that the host plants are prevented from wilting, the service life of the host plants is prolonged, and the times of cleaning the feeding device are reduced.
Further, the absorbent cotton is soaked by water, and the water is added into the absorbent cotton every 1 to 2 days, wherein the water is preferably added until water drops do not naturally drop.
The beneficial effect of adopting the further scheme is that: keeping the fresh state of the host plant and prolonging the service life of the host plant.
Further, the method for breeding the arma chinensis comprises the following steps: placing a spawning medium of newly produced lugworm eggs into a 6-15cm sterilization culture dish with the spawning medium facing downwards and the spawning surface facing upwards, placing filter paper sprayed with distilled water in the culture dish, placing the culture dish in an artificial climate box for culturing, and adding distilled water into the culture dish every day until the lugworm eggs are incubated; transferring the incubated lugworm ovum blocks to a wet cotton block in a breeding container, and adding a proper amount of distilled water to the cotton every day until the lugworm exuviates to 2 years.
The beneficial effect of adopting the further scheme is that: keeping the humidity required by the incubation of the lugworm bugs and providing drinking water for the growth of the nymphs hatched initially.

The inventors also performed statistical experiments on the time to produce host plants. The results of the experiment are shown in FIG. 1. The results in fig. 1 show that both broad bean seedlings and pea seedlings are produced in significantly shorter time than soybean seedlings, so arma bug host plants can be preferably broad bean seedlings and pea seedlings. Compared with the prior method that the host plant is directly put in, or the host plant is cultured by using a water culture finger tube in a feeding container, the operation difficulty is reduced, and the host plant replacement frequency is reduced; the use time of the host plant is prolonged from 3-4 days when the branches and leaves of the poplar and the elm are directly thrown in the water culture of the soybean seedling to 4 days when the soybean seedling is water-cultured to 6.3 days when the soybean seedling is water-cultured, 15.4 days when the broad bean seedling is water-cultured and 12.9 days when the pea seedling is pea seedling. In conclusion, the broad bean seedlings and the pea seedlings can be used as alternative hosts for feeding the arma bug, and a good environment and habitat for the growth and development of the arma bug are improved.
As can be seen from FIG. 2, the longest use time of the young broad beans and the young peas exceeds 10 days, the second use time of the beans is 9.9 days, and the use time of the young soya beans is only 15.4 days.
As can be seen from fig. 3, the development duration of arma bug reared by adding host plant is significantly shorter than that of arma bug reared by not adding host plant, wherein arma bug reared by adding broad bean seedling and pea seedling has the shortest development duration.
From fig. 4, it can be seen that the sex ratio of lugworm by adding the host plant has no significant effect.
As can be seen from fig. 5, the host plants (seedlings) have a certain promotion effect on the yield rate of the arma bug adults, but the yield rate of the arma bug adults fed by the host plants (beans) is significantly reduced compared with the yield rate of the arma bug adults fed by the non-host plants; the reason that the yield of the arma chinensis bred by the kidney beans is low can be that arma chinensis does not like the host, the kidney beans are heavy, and the arma chinensis is mechanically dead after the arma chinensis is greatly collided with a breeding device in the arma chinensis breeding process; to explain the selection of host plants, those with luxuriant branches and leaves and thick leaves should be selected as much as possible.
As can be known from fig. 3-5, in the arma bug breeding process, the addition of the host plant can increase the moving area of the arma bug, reduce the self-disabled behavior of the arma bug, and improve the adult yield of the arma bug; meanwhile, the host plant provides a good habitat for the arma bug, creates a good living environment for the arma bug, and has good promotion effects on shortening the development duration of the arma bug nymph and shortening the production period of the arma bug. The existence of the host plant has no obvious influence on the sex ratio of the adult arma bug.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents, improvements and the like that fall within the spirit and principle of the present invention are intended to be included therein.
