Ethyl formate is an ester formed when ethanol (an alcohol) reacts with formic acid (a carboxylic acid). It is also known as ethyl methanoate because formic acid is also known as methanoic acid. Ethyl formate has the characteristic smell of rum and is also partially responsible for the flavor of raspberries. It occurs naturally in the body of ants and in the stingers of bees. Plant volatiles such as ethyl formate have been shown to have insecticidal properties as fumigant. The efficacy of ethyl formate against insect pests of food commodities, bagged cereals, spices, pulses, dry fruits and oilcakes had been proved. The fumigant was known to provide a high mortality of mixed stage cultures of the key stored product pests, with limited efficacy against the pupal stage of few pests like S. oryzae. The advantages of ethyl formate include natural occurrence in food; rapid kill of insects (2-4 hours); fast breakdown of residues to natural products and low human toxicity. However the fumigant exhibits poor penetration characteristics and high doses (>120 g/t of grain) were required to control internal feeders, which was higher than the flammable limit of 85 g/t. Formulations of ethyl formate in liquid carbon dioxide were found to overcome the problems of flammability and poor penetration.
