Recently, no specific research was approving this method, especially for maize. Maize weevil, Sitophilus maize L is a common destructive insect pest considered many losses on stored grains. The aim of this research is to determined fogging effect on grains to biological effect of S.maize L. This research conducted using a complete randomized design with three levels of fogging durations 0, 15, 30, 45 minutes with three replications. Observation factors were weevil behavior (S.maize L), frasses, and grain level infestation. The results showed that the level of infestation decreased as well as the increasing of fogging duration. Fogging is a good method for safeness of weevil control on stored grain. Formaldehyde in fog affected prevents grains from attacking weevil. Fogging is a cheap and safe control method regarding the environmental issues.

Otherwise corn is also vital raw material for processed food industries. Corn is the second source of carbohydrates after rice which plays a role in supporting food security, adequate supply of animal feed, and has recently even been used as a raw material for alternative energy (biofuel). Based on Department statistic of Indonesia (2015), Several kind of corn are import and exported from Indonesia such as sweet corn, popcorn, dry kernels, and seeds. In end of 2014, recorded land cultivated is 3.8 million hectares and produced at least 19.03 million tons of corn. In order to strengthen the food ecosystem and strengthen national food, the government continues to look for solutions to increase corn production to meet domestic demand for corn, as well as to meet export market demand. The government has prepared a policy related to the acceleration of corn development by establishing a strategy Available online at INSECTA Integrative Science Education and Teaching Activity Journal Journal homepage : https://jurnal.iainponorogo.ac.id/index.php/insecta Article INSECTA Vol. 4 No. 1, 2023, pp. 104 - 109
