Warehouse pest insects contained in commodities can affect the quality and quantity of the commodity. Every industry which has a commodity stored in warehouses makes efforts to prevent damage to the commodity. Control of insect pests during storage is generally conducted by fumigations with phosphine (PH3) and sulfuryl fluoride (SO2F2). This study aims to analyze and compare sulfuryl fluoride and phosphine fumigants in controlling pest insects in the animal feed industry warehouses in Semarang, Central Java. The test insects used are all kinds of insects found on piles of commodities that will be fumigated. The test used is the mortality test. Observations are carried out before and after fumigation takes place. The one-way ANOVA with the Tukey follow-up test was employed to analyze the data. There was a difference in the average mortality of warehouse pest insects between treatments and the highest mortality rate in fumigation using sulfuryl fluoride. Thus, fumigants sulfuryl fluoride and phosphine can affect the mortality of warehouse pest insects. Fumigation using sulfuryl fluoride is easy to apply, more effective, and exposure time is faster compared to phosphine.
The presence of insect pests of warehouses can affect the quality of commodities stored in warehouses. One of the chemicals used for pest control is phosphine. The purpose of this study was to analyze the influence of fumigation process with phosphine fumigant on soybean seeds and bird feed that can be seen from the death of pests in storage warehouses in Semarang, Central Java. Identification is carried out in animal taxonomy laboratory, State University of Semarang is carried out by calculating pest death in each type of commodity. after the data is collected, a one-way ANOVA is involved to analyze the data. Phosphine fumigants are very effective for killing warehouse pests insects especially Tribolium castaneum and Ephestia cautella in soybean seed and bird feed commodities. For future warehouse pest control it is recommended to use biopestiside to be safer for food safety.
Insects warehouse pests contained in commodities, especially tobacco, can cause a decrease in the quantity and quality of commodity. The main pest insects found in tobacco storage warehouses are Lassioderma serricorne and Pholcus phalangioides. This study aims to analyze and compare the effectiveness of the use of fumigant storin to control insect pests L. serricorne and P. phalangioides. Methods used in this study include preparation of test insects, fumigation application, identification, calculation of mortality, and data analysis. The data were analyzed statistically using the One Way ANOVA test. The results showed that there was a significant difference in morphility between groups of test insects. Mortality is highest in the L. serricorne test insect group, which indicates that fumigant storin is very effective in controlling barn pest insects, especially L. serricorne. To control insect pests warehouses in the future, it is recommended to use biopesticides to be safer for food.

This study aims to analyze and compare the effectiveness of phostoxin fumigants to control insect pests L. serricorne and P. phalangioides. Methods used in this study include preparation of test insects, fumigation application, identification, calculation of mortality, and data analysis. The data were analyzed using one way ANOVA test. The results showed that there was a significant difference in morphility between groups of test insects. The highest mortality was in the group of test insects L. serricorne, which indicated that phostoxin fumigants effectively controlling barn insect pests, especially L. serricorne.
