Abstract

The present study was carried out during spring seasons, 2020 and 2021,the study aimed to evaluate the feeding of silkworm Bombyx moriL. on different artificial diet (T1-T2) in 2020 season and (T1-T2-T3) in 2021 season , on some biological, and technological aspects. The results indicated that the best results were recorded with T2 diet especially for larvae which fed on young instar (R1  which fed in 1 st and 2nd instar) and R2 which fed in 1st ,2nd  and 3th), during the first season.While in the second season, the best results were noticed also with the larvae which fed on young instarin the treatments (T1 and T2) and the same sub treatment (R1 and R2) in comparison with other diets and control for biological indexes (larval weight and larval duration) and silk filament characteristics. The current study supports the trend towards the use of artificial diets during the 1st and 2ndinstars, due to its importance in the process of natural silk production.
