A laboratory study was conducted to determine the effect of the turbinate, alkaloid and phenolic extract of castor beetle leaves on the 24 and 120-hour virginal cycles of the southern cowpea beetle C. maculates and with three concentrations of 3%, 5% and 7%, as the concentration of 7% of the alkaloid extract exceeded the mortality rate for both phases, which amounted to 90% and 75% for the 24- and 120-hour-old pupae, respectively. The turbinate, phenolic and alkaloid extracts also showed With the three concentrations, there were percentages of destruction, partial eruption, and distortions, as the maximum percentages reached 7% of the turbinate extract when treating 120-hour-old virgins, whose partial eruption percentage reached 65%, while in the 3% concentration of the alkaloid extract the percentage of partial eruption and distortions reached 30 % for a lifespan of 120 hours.
