Description

A method for increasing locust egg production and locust egg collection

technical field

The invention relates to a method for increasing locust egg production and collecting locust eggs.

Background technique

Turtle-like insects belong to Coleoptera, Heteromera, Tenebrioidea, and Meloidae. The insects have multiple metamorphosis life history, larval parasitism, adult gregariousness, chemical defense, drought tolerance, etc. Interesting biological properties make it seem strange. Among them, the larvae of some taxa of Coriander are semi-parasitic predators, parasitic in locust oocysts or hives, and feed on larvae of locusts or bee species. Cantharidin, which can be secreted by adults of Melaleuca japonica, belongs to terpenoids and has obvious anticancer activity and insecticidal activity. Turmeric has shown importance in pharmacology, veterinary medicine and agriculture.

Turmeric is one of the traditional Chinese medicinal materials in China, which has important medicinal value because it contains Cantharidin (C ₁₀ H ₁₂ O ₄ ). Cantharidin is highly toxic, and external use can erode dead muscles, apply scabies, and remove malignant sores, and oral administration has the effects of attacking toxins, dispelling blood stasis and dispelling stagnation, and antitumor. With the clinical discovery of the therapeutic effects of cantharidin drugs on cancer and other diseases, it has aroused widespread concern and extensive research on the cantharidin and its contained cantharidin. one.

In recent years, with the continuous and stable development of China's economy and the improvement of per capita living standards, the breeding of coriander leaves is still in the exploratory stage, and there are no reports about large-scale artificial breeding. Therefore, we generally pay close attention to its entire life history and behavioral conditions. However, the most difficult stage of raising celery is the larvae, mainly because larvae feed on locust eggs, and it is difficult to obtain locust eggs. .

At present, the method of obtaining locust eggs for feeding the larvae of B. japonica mainly adopts the method of field collection, which is time-consuming and laborious, and the amount of locust eggs obtained is small. Moreover, in the wild, locusts often lay their eggs below the soil layer 5cm, which has the advantages of A small part is produced on rice root piles, which is difficult to collect; locust eggs are collected in the field, even if locust eggs are obtained from rice piles, it is very limited. In short, obtaining locust eggs in the field is not only time-consuming and labor-intensive, but also the collected locust eggs are limited and the overall structure is incomplete.

Contents of the invention

detailed description

The invention is further described below in conjunction with specific embodiments:

Example:

A method for improving locust egg production and locust egg collection, comprising the following steps:

(1) Cultivate rice seedlings: Soak the rice seeds until they are white, sprinkle the white rice seeds on a seedling tray with absorbent paper, put them in an artificial climate box, set the temperature at 30~35°C, and the humidity at 70%. The photoperiod is 14L:10D for accelerating germination; after germination, put it into a plastic pot with field soil samples for breeding and set the temperature in the artificial climate box at 29°C, the humidity is 70%, and the photoperiod is 14L:10D. Paddy rice grows to 20-25cm, obtains rice seedling, for subsequent use; The plastic basin that adopts is long 40cm, wide 30cm, height is 12cm.

(2) Create a locust breeding environment: place locust breeding cages in an artificial climate box with a temperature of 28°C, a humidity of 70%, and a photoperiod of 14L:10D, and place an open-faced The box body is equipped with quartz sand for locusts to lay eggs, and the humidity of the quartz sand is kept at 30%. The length and width of the adopted cage are 45cm, and the height is 60cm. , a plastic box with a width of 14cm and a height of 5cm;

(3) Raising locusts: put the locusts collected in the field in breeding cages for raising, and at the same time put the rice seedlings obtained in step (1) into the raising cages for the locusts to eat, and replace the rice seedlings regularly;

(4) Collect locust eggs: locusts lay eggs in quartz sand, take out the box after the eggs are covered with quartz sand, add water to the box, pan out the locust eggs, and put the eggs in the refrigerator for storage , and the storage temperature is 4°C.

According to the above-mentioned steps, when locusts were raised, six treatment groups were set, that is, six locust raising cages were set, and 25 pairs of locusts of the 5th age were put into each raising cage, and finally the locusts in each raising cage were collected respectively when they were born. Grasshopper eggs on the egg matrix quartz sand, and the egg production of each treatment group were counted separately to obtain the data of the test group (see Table 1).

Comparative example:

In building the locust breeding environment, the quartz sand for the locusts to lay eggs in the box body of the raising cage is replaced by a field soil sample with a humidity of 30% collected in the field. 2 locust rearing cages, put 25 pairs of locusts of the 5th instar in each raising cage, collect the locust ovum of locusts in each raising cage respectively on the field soil sample of the oviposition substrate respectively at last, and count the production of each treatment group respectively The amount of eggs was obtained from the data of the control group (see Table 1)

The results show that: after comparing the test group and the control group, it can be seen that locusts like to lay eggs in quartz sand as the oviposition substrate, and the amount of eggs laid is 39.4% higher than that in field soil samples. Moreover, locust eggs are laid in soil samples in the field, which is inconvenient to find and take eggs. On the contrary, locusts lay eggs in ordinary quartz sand, and eggs are easy to get. You only need to add A certain amount of water can wash out the locust eggs.
