Widespread use of pesticides represents a potential risk to human and environmental health. Hence, biopesticides from plants are some of the future strategies for plant protection. In this regard, a seed extract of Annona squamosa was prepared and found to be a promising pesticide. In order to establish the inherent toxicity and non-target safety required for registration and marketing of pesticides, toxicological studies are conducted. The genotoxicity potential was evaluated in rats with 75, 150 and 300 mg/kg Annona squamosa by the comet assay in leucocytes, micronucleus and chromosomal aberration tests in bone marrow. We also studied the effects of 300 mg/kg of extract on lipid peroxidation, reduced glutathione level and glutathione S transferase activity in liver, lungs, brain, kidneys, heart and spleen of treated rats. The comet assay showed a statistically significant dose related increase in DNA migration. The micronucleus and chromosomal aberration tests revealed a significant induction in frequency of micronuclei and chromosomal aberrations at 150 and 300 mg/kg. Annona squamosa treatment significantly enhanced lipid peroxidation, decreased glutathione and glutathione S transferase levels revealing the oxidative stress condition. Our results warrant careful use of Annona squamosa seed extract as a biopesticide till more tests are carried out. (C) 2009 Published by Elsevier Ltd.
