Uses of Jellyfish in Pre Sowing Seeds Treatment and Pest Control

Abstract

Aim: Preliminary experiment on the effect of liquefied Jellyfish on seedling growth and the digested solution of jellyfish as insecticides. Place and Duration of Study: Natural Products Research Department, National Center for Radiation Research and Technology, Atomic energy authority. Methodology: Seeds of anise, canola, coriander, cumin and dill were experimented to study the effect of presowing soaking treatment in liquefied Jellyfish on seedling growth. Also, different concentrations of digested solution of jellyfish were examined as bio-insecticide against two insects Oryzaephilus surinamensis L. and Bactrocera zonata (Saunders). Results: Enhancement in germination parameters were observed in comparison to untreated control. The changes in protein pattern in seedlings from seeds soaked in liquefied jellyfish solution were investigated. Most of electrophoretic protein patterns in coriander weren’t affected by soaking in jellyfish. But, in dill or in canola seedlings new bands were created in samples from seeds soaked in jellyfish compared to those separated from control soaked in water. On the other hand, the digested solution of jellyfish was highly toxic with LC50 of 2.06 and 1.14 % for O. surinamensis and B. zonata, respectively. Conclusion: These data suggest that liquefied jellyfish is useful as a priming solution for plants and its digested solution as bio-insecticide.
