Series experiments were conducted to evaluate the effectiveness of the crude extract of alkaloid compounds of residue of the tobacco plant Nicotiana tabacum in the mortality of Ephestia cautella.
The highest mortality rate of the larval stages was 90% of when the extract used in at 10% concentration after 48 hours, compared with 26.56,26.56,17.70, 17.70,17.70% in the larval stage 1st ,2nd ,3rd ,4th ,5th , respectively, of the control treatment. It was found a linear correlation between the mortality rates with increasing the concentration of the extracts.
Pupal mortality rates increased from 17.70 % in the control treatment to 90% at all concentrations of the extracts.
