Study of chemical composition and antimicrobial activity of mud dauber wasps nest soil

This study involves determination of the chemical composition of wasp’s nest soil and simple clay soil. The samples were analyzed at Biotech Lab. S.D. (PG) College Sri Ganganagar, a high standard laboratory with sophisticated equipments. Research showed that it builds nest by excreting saliva to mixture of water and various building materials which include paper and clay soil. The nest soil was found to be higher in concentration of phosphorus, magnesium, chloride, potassium (very low amount), calcium, phenol and iron. Antimicrobial activity test was showed positive result on four different pathogenic microbes such as Escherichia Coli, Pseudomonas aeruginosa and Bacillus subtilis against nest soil where as Staphylococcus aureus showed higher inhibition zone.
