Abstract

The present work has been carried out at Plant Protec. Dept. Fac.
of Agric., El Fayoum Univ. during spring season of 2014 to study the
effect of Pimpinella anisum as food additives on spinning of silkworm,
Bombyx mori L. Dried seeds of P. anisum were crushed and dissolved
in distilled water to prepare different concentrations (5, 10, 15, 20 and 25
mg/ml.). In the present study, results showed that, the concentration 10
mg/ml. of P. anisum occupied the first category to improve the most
studied parameters of B. mori L. when comparing to control. Where 5th
instar mortality percentage recorded 5% compared to 10% in control. 5th
instar larval duration were 10.40 days compared to 10.44 days in control.
Cocooning percentage were 96.82% compared to 92.22% in control and
cocoon indices were 1.192 g, 0.253 g and 21.23% for cocoon, cocoon
shell weights and cocoon shell ratio comparing to 1.088 g, 0.194 g and
17.90% for the control respectively. Total haemolymph protein
registered 75.90 mg/ml compared to 67.52 mg/ml in control. Protease
enzyme were 64.33 µg alanine/min/ml compared to 57.21 µg
alanine/min/ml. in control and silk productivity were 2.434 cg/day
compared to 1.866 cg/day in control.
