The most destructive granary pest in South America is Calandra 

 oryzae, which has four generations in a year, or five if the winter is 

 warm. A less important pest is Tinea granella, which attacks exclu- 

 sively wheat, barley and rye. The appearance and habits of these 

 pests are described. Fumigation is recommended with carbon bisul- 

 phide, carbon tetrachloride or sulphurous anhydride. In the case 

 of the last-named, 5 j oz. of sulphur are mixed with 3^ oz. of saltpetre ; 

 the mixture is ignited and allowed to burn for 24 hours, the granary 

 being hermetically sealed during the operation. It is then thoroughly 

 ventilated, and the walls, roof, etc. disinfected with a 2 per thousand 

 solution of corrosive sublimate. The quantities given are sufficient 

 to fumigate 50 cubic metres (1,766 cubic feet).
