Evaluation of the efficiency of alcoholic propolis extract and Bacillus thuringiensis in the mortality rate of the third larval age of the great wax Moth Galleria melonella (L.)

This study was conducted at the AL- Musayyib Technical College / Department of Biological-Control Techniques for the period from 1/10 /2021 to 15/3/2022. The study aimed to compare propolis extract and B. thuringiensis bacteria on the larvae of the major wax moth. The direct treatment of the larvae of the major wax moth and the food provided to them (natural wax) indicated that the organic extract (ethyl alcohol) of Propolis showed effectiveness in destroying the third larval age the major wax moth.The results showed that there were significant differences between the concentrations of the extract in the percentage killing percentages depending on the concentration and the duration of exposure, if the highest rate of the killing percentage in the concentration reached 3%, reaching 76.6% within a week of the treatment, while the lowest rate of killing at the concentration was 2%, as it reached 53.3% % during the first day of the transaction.Using different dilutions of the bacterial suspension of B. thuringiensis had a significant effect on the percentage of killings for the third larval age of the Great Waxworm after different exposure periods of the treatment
