Abstract:
The study was conducted under the laboratory conditions of the laboratory of insects and agricultural animals, Department of Plant Protection Faculty of Agricultural Studies University of Sudan for Science and Technology Shambat in the period from September 2017 to November 2018 to study the effect of Neem powder and propolis on the biological and the mortality rate of larvae KhabrabeetleT. granarium.
Three factors were used in this experiment in addition to the witness, and the effect of these parameters on the lesion was evaluated.
The results showed that the coefficients used in comparison with the control showed no significant effect on the growth and development of the larval stage.
In contrast, the neem and propolis mixture gave the best effect on larval stage mortality at an average of 0.135 compared to the neem treatment, which gave an average of 0.09. The treatment with propolis powder gave an average of 0.06 compared to the average 0.03
Summation: Treatment with the mixture of neem and propolis leaves contains some ingredients that have proven the experience of the ability of the mixture to kill the larvae of the beetle at different times, which is considered useful for the continuation of this type of research.
