Problems solved by technology

Since the indoor temperature and humidity will change during the actual production process, and some pupal skins are relatively dark in color, it is difficult to accurately measure the development process of the pupae using traditional methods, which will affect the arrangement of seed production , there is an urgent need to find a new method for detecting pupal development in production

Embodiment 1

[0022] Embodiment 1: A kind of assay method of developmental process of silkworm male pupae

[0023] (1) Materials and equipment:

[0024] The silkworm chrysalis adopts a variety bred by Suzhou University (Suxiu×Chunfeng), which was approved by the Silkworm Variety Approval Committee of Jiangsu Province in 2010. sex. The incubator is a 250D artificial climate box produced by Guangdong Shaoguan Xinteng Science and Technology Instrument Co., Ltd., and the balance is an electronic balance with a precision of one ten-thousandth of a gram produced by Shimadzu Corporation of Japan.

[0025] Samples: Take 10 pupated silkworm chrysalis for the construction of the model, and another 1 pupated silkworm chrysalis for the detection of developmental process.

[0026] (2) Stacking and quantity collection

[0027] Raise silkworms to the upper cocoon by conventional methods, pick the cocoons after 3 days in the cocoons, cut open the cocoons and take out the silkworms that have not pupated,...

Abstract

The invention discloses a silkworm pupa development process determination method. The method specifically includes the steps of (1), constructing mathematical models of relevance between to-be-determined silkworm pupa development processes and metabolism decrease quantity; (2), taking more than one silkworm pupa from to-be-determined silkworm pupae to sex, weighing pupated silkworm pupae, and computing accurate silkworm pupa development processes according to the weight of the taken silkworm pupae at the to-be-determined moment and the female and male pupa mathematical models. The novel silkworm pupa development process determination method has the advantages that the gap that the current market lacks a method capable of accurately determining the silkworm pupa development processes is filled, errors caused by artificial judgment and environmental change can be decreased, and the method is simple and convenient to operate and can be applied to silkworm breeding and accurate pupa development process determination of laboratories.

Description

technical field [0001] The invention belongs to the technical field of silkworm breeding, and in particular relates to a method for measuring the development process of silkworm pupae, which can accurately determine the development process of pupae. Background technique [0002] The silkworm (Bombyx mori L.) has been domesticated in my country for more than 5,700 years. It belongs to the complete metamorphosis insect of Lepidoptera Bombyridae, and its generations include egg, larva, pupa and adult (moth). Bombyx mori has four different stages of development, and its internal and external representations are also different: the egg is the stage of embryonic development, the larva is the stage of absorbing nutrients from the outside world, the pupa is the transition stage from larva to moth metamorphosis, and the adult is the stage to complete the reproduction of offspring. Since the pupa of silkworm does not need to absorb nutrients from the outside, it needs to consume a lot...
