Abstract
The results study of efficiency of the alkaloid and phenolic extract of the seeds and leaves of the sesban plant in the average percentage of mortality the larvae of the red rusty flour beetle T. castaneum showed a variation in the average percentage of mortality insect larvae, are reached 62.08 and 73.75%, respectively. The results of the statistical analysis showed that there was a clear significant difference in the average percentage of mortality the larvae for both extracts. The results of the study showed a variation in the effect of the extract of the plant part of the seeds and leaves of the sesban plant on the average percentage of mortality insect larvae, which reached 67.08 and 68.75%, while the results of the effect of the concentrations of the alkaloid and phenolic extract were 0.25, 0.50, 0.75 and 1%, to the average percentage of mortality insect larvae directly proportional to The studied concentrations increased and reached 50.00, 65.00, 72.50, and 83.33%, respectively. The results of the study showed the LC50 values and the relative toxicity of the alkaloid and phenolic extract of the seeds and leaves of the Sisban plant, indicating that the alkaloid extract of the leaves of the Sisban plant was superior to the rest of the studied extracts. The LC50 value reached 0.284 and the relative toxicity was 151.41 compared to the alkaloid extract of the seeds of the Sisban plant, which gave the lowest toxicity with an LC50 value of 0. 430 and a relative toxicity of 100.
