USE OF SULPHUR AS A REMEDY FOR THE INDIAN-MEAL MOTH. 



Mr. A. Martin, Larnont, S. Dak. . writes, under date of November 3, 

 1900, that during the summer of 1899 the Indian-meal moth (Plodia 

 interjmnctella Hbn.) became so numerous that he was obliged to have 

 recourse to remedies. Having a hard-coal heater in the building in 

 which the infested grain was stored, he decided to make an experi- 

 ment. The first was to ascertain if coal gas and heat would have any 

 effect on his unwelcome guests. Neither produced the desired result. 

 On the contrary, the heat enabled the insects to multiply more rapidly. 

 and the grain for a foot or so nearest the heater became quite hot — as 

 high as 110° F. 



Sulphur was tried, 3 pounds being burned in a couple of days, with 

 result that it killed some of the moths, the fumes not being strong 

 enough to effect the destruction of the larvae. He next tried 3 pounds 

 of sulphur, repeating with 3 pounds more. This killed all the moths 

 not protected by being under boards or in similar localities. It did 

 not affect the larvee as far as could be seen. Our correspondent esti- 

 mates that the moths could all be killed at an expense of about, say, 

 5 pounds of sulphur to 10,000 cubic feet. 



Bisulphide of carbon cost, in this case, 25 cents a pound, and was 

 therefore too expensive. 



FULLER'S ROSE BEETLE IN THE HAWAIIAN ISLANDS. 



Since writing on the so-called ;i olinda bug" (Pandamorus olinda 

 Perk.), in " Notes on insects affecting the koa trees at Haiku Forest, 

 Maui," specimens were given to me at San Francisco by Mr. Charles 

 Fuchs, who claims that they were common in gardens of that city. 

 Mr. E. A. Schwarz, to whom we showed specimens, pronounced them 

 the well-known 4i Fuller's rose beetle" (Aramigus fuLleri Horn). The 

 insect has been figured in the Report of the Entomologist of the 

 Department of Agriculture for 1879. 1 Dr. Riley states that as early 

 as 1875 specimens were sent to him by Mr. A. S. Fuller, who found 

 it in greenhouses somewhat injurious to camellias. In his report, Dr. 

 Riley stated that '* it seems to be quite widespread, occurring from the 

 Atlantic at least as far west as Montana, and its habit of injuriously 

 affecting roses and other greenhouse plants must be looked upon as a 

 comparatively recent acquirement." 



The so-called ''Olinda bug" is found on Oahu, and lately occurred 

 in destructive numbers at Kohala and Kau, on Hawaii. The injury of 

 this beetle to trees is in reality not as serious as it would appear, and 

 its presence upon older trees is barely noticed, while upon the young 

 trees growing among the Hilo grass its presence is more apparent. 



1 More recently Mr. Chittenden has given an account of this species in Bui. 27, 

 n. s., pp. 88-96.
