Indian meal moth Plodia interpunctella (Lepidoptera-Pyralidae) is one of the most serious stored grain pests worldwide. Destruxin is a cyclic hexadepsipeptides produced by entomopathogenic and phytopathogenic fungi, it is contains five amino acids and one hydroxyl acid. The effect of Nano-extracted Destruxin from Metarhizium anisopliae was evaluated against the target pests. Results showed thatthe LC50 obtained 103X10 ⁴ and 77 X10 ⁴ spores/ml for Destruxin and nano-Destruxin treatments, respectively. Under laboratory conditions, the number of eggs laid / female were significantly decreased to 17.4±3.8 and 10.6±9.5 eggs / female after destruxin and nano-destruxin applications, as compared to 99.9±7.9 eggs/female in the control after 120 days. The adult emergence recorded 100% in the control which is significantly decreased to 2% after nano - destruxin treatments after 120 days of application under laboratory conditions. Under store conditionsthe number of eggs laid /female were significantly decreased to 13.1±9.2 after nano - Destruxin treatments after 120 day of storage.
