Author(s):

Abstract:
Larvicidal activity of Hexane and ethanol seed extracts of Annona squamosa were studied against third instar larvae of Spodoptera litura at different concentration (5, 10, 15, 20 and 25 mg/ml. The plant seeds were dried, powdered and extracted in soxhlet apparatus in hexane and ethanol solvent for 24 hrs. The third instar larvae of S. litura were exposed to various concentration and percent mortality were recorded after 96hrs.
The larvicidal activity of seed extract of A. squamosa were (LD 10= 5.91 mg/ml, LD 50= 13.9878 mg/ml) in hexane and (LD10= 11.72 mg/ml, LD 50= 22.48 mg/ml) in ethanol respectively. Results revealed that the mortality was increased with increasing in concentration of the plant extracts.
The hexane solvent extract of A.squamosa showed higher larvicidal property against third instars larvae of S. litura. Statistical variance, 95% confidence limits and regression equations are presented.
