Problems solved by technology

[0003] In 1999, our laboratory improved the feed formula of the cotton bollworm, which greatly increased the survival rate, egg production, egg hatching rate, etc. of the cotton bollworm. Directly connect the newly hatched larvae to the feed in the glass tube, 1-2 heads per tube, pick out the 3rd instar larvae with uniform growth from the tube after 7 days, and transfer them to the tube with new feed to continue to raise; This method requires more labor and higher cost (Liang Gemei et al., 1999)
In 2003, Fan Xianlin and others improved the breeding method of cotton bollworm, and proposed that the newly hatched larvae be picked into 10-hole rearing bo

Example Embodiment

[0022] Example 1

[0023] This embodiment is used to illustrate a device for improving the efficiency of artificial breeding of cotton bollworm.

[0024] The main body of the device is a 24-hole plate. According to the size of the 24-hole plate, a piece of blow-molded paper (purchased by ordinary stationery stores) with the same size as the cover of the 24-hole plate is cut and placed in the upper cover.

Example Embodiment

[0025] Example 2

[0026] This embodiment is used to illustrate a method for improving the efficiency of artificial breeding of cotton bollworm.

[0027] Take 1g-2g of artificial feed into the 24-well culture box of the device described in Example 1, and then pick up the newly hatched cotton bollworm larvae in a 24-well plate, connect 3 larvae in each hole, close the lid, tie it with a rubber band, and put it Raise under the conditions of temperature 27±1℃, relative humidity 70±10%, photoperiod 14L:10D; each treatment is repeated three times ( figure 1 ). Take the 24-well plate treatment directly covering the upper cover without blowing paper as a control.

[0028] During the period, the number of larvae and developmental age of the cotton bollworm in the 24-well plate were observed every day. SPSS 18.0 software was used to analyze the significance of the difference. The t test compared the difference between blown paper and no blown paper, and evaluated the use of blown paper to re...

Abstract

The invention relates to insect breeding, and particularly discloses a device and method for improving artificial feeding efficiency of cotton bollworms. The device mainly comprises a pore plate. Blow molding paper with the same size as an upper cover is added into the upper cover of the pore plate. The method comprises the steps that cotton bollworms are bred through the device to third instar larvae, and third instar larvae growing uniformly are selected and transferred into a bollworm breeding pipe to continue to be bred to pupate. In order to solve the problems that young cotton bollworm larvae are high in escape rate, uneven in development progress, prone to cross infection and the like, newly hatched larvae are bred in the 24-pore plate, the blow molding paper is added for prevent escape, and third instar larvae are transferred into the glass bollworm breeding pipe to be bred. By means of difference between the effect obtained by adding the blow molding paper and the effect obtained by adding no blow molding paper, it is proved that the blow molding paper has the beneficial effect on lowering the larva escape rate and improving development uniformity.

Description

technical field [0001] The present invention relates to insect feeding, in particular to the artificial feeding of cotton bollworms. Background technique [0002] Cotton bollworm is an important pest that damages a variety of crops. People have carried out a lot of research on the ecology, biochemical mechanism, molecular mechanism, and control technology of cotton bollworm. An important guarantee for all kinds of research. [0003] In 1999, our laboratory improved the feed formula of the cotton bollworm, which greatly increased the survival rate, egg production, egg hatching rate, etc. of the cotton bollworm. Directly connect the newly hatched larvae to the feed in the glass tube, 1-2 heads per tube, pick out the 3rd instar larvae with uniform growth from the tube after 7 days, and transfer them to the tube with new feed to continue to raise; This method requires more labor and higher cost (Liang Gemei et al., 1999). In 2003, Fan Xianlin and others improved the breeding ...
