Embodiment 1

[0025] Embodiment 1 The configuration of the artificial diet of the large lacewing

[0026] Materials and proportions required for feed: The artificial feed formula of the present invention includes two major types of substances, main and added component groups. By weight percentage, the main component group accounts for 88-90% in the artificial feed formula, and the added component group accounts for 10-12%. The main component group is a mixture of fresh eggs, pork and pork liver mixed evenly with the same weight. The added ingredient group consists of sucrose, brewer's yeast powder and appropriate amount of antibiotics.

[0027] Feed configuration method: Break pork and pork liver, mix with eggs, and place in a sterilized container. Two major categories of substances, the main and the supplementary ingredient groups, are placed in containers. Stir well. , divided into small bags for later use.

Embodiment 2

[0028] Example 2 Effects of Artificial Diet on the Growth and Development of Lacewings

[0029] Lacewings were raised with the artificial diet configured in Example 1, and the experiment was repeated three times, with 30 nymphs in each repetition. No. 1 is raised with artificial feed; No. 2 is raised with aphids, and raised with the artificial feed configured in Example 1.

[0030] The artificial diet of table 1 embodiment 1 configuration is on the influence of the growth and development of the large lacewing

[0031]

[0032] Note: The data listed in the table are mean ± standard error. The same letter in the same column indicates no significant difference, and the same column with different letters indicates significant difference.

[0033] As can be seen from Table 1, the artificial feed configured in Example 1 was used to raise Da Caoling, and the larval duration was significantly longer than that of the lacewing raised with aphids, and the survival rate was also lowe...

Embodiment 3

[0034] The impact of embodiment 3 artificial diet on the lifespan and reproduction of the large lacewing

[0035] Raise the lacewing with the artificial feed configured in Example 1, and observe the effect of the artificial feed on the lifespan and reproduction of the lacewing. The experiment was repeated three times, with 16 pairs of adults per replicate. No. 1 is feeding with artificial feed; No. 2 is feeding with aphids. The test results are shown in Table 2. As can be seen from Table 2, the artificial feed configured in Example 1 is used to raise the large lacewing, although there is a significant difference between the average amount of eggs laid per female in the control group and the artificial feed group, the statistical analysis results of the life expectancy of the male and female worms in the control group and the artificial feed group are not significant. difference. At the same time, there was no significant difference in the statistical analysis results of the...

Abstract

The present invention relates to a predator Chrysopa pallens artificial feed and a preparation method thereof. The artificial feed formula includes fresh eggs, pork and pork liver. The artificial feed is characterized by low cost, simple and convenient preparation and wide and easily acquired material sources due to commercialized raw materials. In addition, the artificial feed can ensure Chrysopa pallens breeding generations and meet the needs of predator Chrysopa pallens mass rearing. The invention provides the artificial feed formula and preparation method for mass rearing of predator Chrysopa pallens and key technical support for application of mass-reared predator insects to biological control, and is of good practicability.

Description

technical field [0001] The invention belongs to the technical field of insect artificial feed and insect artificial breeding, and specifically relates to a formula of predatory natural enemy insect artificial feed and its preparation, especially an artificial feed formula suitable for Dacaoling and its preparation technology. technical background [0002] The biological control of natural enemy insects is safe, can avoid environmental pollution and residues in agricultural products that cause food safety and other issues, and can also protect the agricultural ecological balance, which is conducive to long-term control of insect pests below the level of economic harm. Therefore, the use of natural enemy insects The biological control has been more and more people's attention. [0003] Natural enemy insects play a very important role in population control of crop pests in nature. Some important natural enemy insects have successfully reproduced in large quantities on artifici...
