Abstract
The effects of feeding silkworm larvae (Egypt hybrid, Giza ) on mulberry leaves supplemented with three foliar fertilizers compounds, Basfoliar combi ctip, Tecamin max and Stimoful at three concentrations (1.0, 2.0 and 3.0 % each) for one time (at the beginning of fourth instar) and two times (at the beginning of fourth and fifth instars) on some biological and technological characters were studied. Basfoliar combi ctip and Stimoful compounds at 2% kept the larvae healthy by decreasing mortality rate.In adation, a concentration of 3% of each Basfoliar combi ctip and Stimoful compounds shortened the larval duration when used one or two times. Basfoliar combi ctip and Stimoful compounds caused the highest cocooning percentage compared with control. Adult emergency increased when mulberry leaves were enriched with Basfoliar combi ctip and Tecamin max fertilizers at 2% and Stimoful fertilizer at 3% compared to control. Stimoful at 3% and Tecamin max at 2% compounds resulted the highest female fecundity when it  applicated two times and one time, respectively. Fresh cocoon weight and cocoon shell weight showed significant increase when Stimoful compound used at 2% and 3%, Tecamin max at 2% and Basfoliar combi ctip at 3% respectively. Meanwhile Basfoliar combi ctip compound at 2 and 3% and Stimoful compound at 2% increased the silk content ratio compared the control. Tecamin max, Basfoliar combi ctip compounds at 2% each and Stimoful compound at 3% gave longer and heavier silk filament than the control.
