Abstract
The effect of Zingiber officinale was studied on mortality
percentages and cocoon shell ratio of silkworm, Bombyx mori during
spring season of 2015 at Plant Protec. Dept. Fac. of Agric., El Fayoum
Univ. The powder of Z. officinale was dissolved in distilled water to
prepare different concentrations (10, 20, 30, 40 and 50 mg/ml.). In the
present study, results showed that, the concentration 20 mg/ml. of Z.
officinale occupied the first category to reduce 1st , 2nd and 3rd instars
mortality percentages. While 40 mg/ml. of Z. officinale occupied the
first category for reducing 4th & 5th instars mortality percentages and
improving cocoon shell ratio.
