The invention relates to a regulation and control method for synchronous eclosion of middle and later-stage pupae of a silkworm cross variety, and belongs to the technical field of silkworm improved variety breeding. The method aims at solving the problems that existing strong low-temperature inhibition causes pupa physiological injury and synchronous regulation and control in the middle and later periods are insufficient. According to the technical scheme, after cocoons are cut and pupae are identified in the middle stage of pupa body development, female and male pupa forms are observed every day, quantitative scoring is conducted, and comprehensive development scores of two groups are calculated and compared; therefore, differentiated temperature protection is performed on male pupa groups which develop quickly or slowly, and meanwhile, the residual development time difference of the two parties is estimated according to a pre-established development progress comparison table. When the time difference exceeds a set threshold value, physical stimulation is applied to the lagging party, and if the lagging party enters a key window before eclosion, a nutritional agent is synchronously sprayed and supplemented; and after the development of the two parties reaches the standard, differential photosensitive management is executed to trigger synchronous eclosion. The method is mainly used for improving eclosion synchronism and health degree of pupae in silkworm seed production, so that silkworm egg quality is improved.

This invention discloses a cocoon silk deburring mechanism for a silk reeling machine. The mechanism is specifically designed to remove cocoon silk fibrous material from the reeling machine. The cocoon silk passes through the narrow slits of a separating plate, the spacing of which is greater than the diameter of the cocoon silk but smaller than the diameter of the cocoon silk fibrous material. When cocoon silk fibrous material passes through, the separating plate automatically cuts the cocoon silk, preventing the cocoon silk fibrous material from entering the raw silk, thus achieving the purpose of removing the cocoon silk fibrous material. Furthermore, as reeling progresses, the cocoon silk fibrous material on the surface of the cocoon is gradually removed, the pupa falls off, and the weight of the cocoon becomes lighter, potentially causing the cocoon to be lifted up along with the cocoon silk fibrous material (i.e., "pupa lifting"). Under the action of the separating plate, the cocoon silk fibrous material of the pupa lifting is cut off, thereby preventing pupa lifting and avoiding problems such as machine downtime or damage to the ceramic eye caused by pupa lifting. After the cocoon silk is cut, new cocoon silk is added to the silk reeling plate by means of a silk-adding mechanism, thereby achieving the effect of continuous silk reeling without stopping the machine. There is no need for manual removal of rough silk, which improves the mechanical automation level of the silk reeling machine and reduces the labor intensity of workers.
