Bio-Activity Assay of Arid Region Plant Prosopis Cineraria on Adult Emergence of Pulse Beetle, Callosobruchus Chinensis Lin.

The powdered samples derivedfrom the fruit, leaf, and bark of the Prosopis cineraria (L.) plant were evaluated for theirability to safeguard green gram seeds from damage caused by the pulse beetle Callosobruchus chinensis. The biologicalparameter examined for C. chinensis was "Percentadult emergence," which refers to the proportion of adult insects thatemerged from the green gram seedsupon which C. chinensis lay its eggs. Formulations derived from plant extracts were observedto inhibit the development of the pulse beetle from the egg stage to the adult stage and eliminate it within thegrain. The ovicidal and larvicidal effects of P. cineraria were demonstrated, as the extractsdramatically decreased the percentage of adult emergence by 56 to 93% at a 5% level of significance,compared to 96% in control groups. A minimum adult emergence rate of 56.68% was recorded in the groupstreated with 10% aqueous bark extract of P. cineraria.Significant inhibition of emergence was seen in groups treated with 10% fruit formulations, with a range of 56 – 59%.
