pest, essentially a horticultural one. as feeding upon a field crop. 

 The insect is night flying and feeds only after nightfall, secreting 

 itself during the day in the loose soil beneath its food plant, among 

 rubbish on the ground, or in crevices such as found between the stem 

 or trunk of a plant and the soil. 



REMEDIES. 



Hand picking in the seed beds will free the seedlings from this pest 

 in one or two nights. If thereafter the seed beds are protected by a 

 covering after sundown, relief from further injury will be secured. 

 A box frame with cloth across the top could be cheaply made for this 

 purpose, easily handled, and would last for several seasons. 



The greatest injury to tobacco from the Japanese rose beetle will 

 doubtless occur in the field, for the reason "that this insect feeds, as a 

 rule, on the more matured leaves of plants. The beetle may not 

 prove to be a serious tobacco pest, as it might possibly have invaded 

 the experimental plat from neighboring plants where it had exhausted 

 its primary food supply. Should the work of the pest become serious 

 in the field, it can be controlled by an arsenical poison as for the flea- 

 beetle and splitworm. Arsenate of lead has been used with success 

 against this pest on roses and other ornamental plants. Regarding a 

 remedy for the beetle on roses, Professor Koebele says: 



One ounce of Paris green mixed with 4 pounds of flowers of sulphur, and dusted 

 thickly over the rose and other affected plants, has so far proved one of the best 

 remedies against that serious pest, the so-called rose bug, Adoretv.s wmbrosus. a 



THE CIGARETTE BEETLE. 



(Lasioderma serricorne Fab.) 



Having considered the pests of the growing tobacco plant, we now 

 pass to one injurious to the cured and manufactured product. The 

 cigarette beetle is the most common and destructive pest of stored 

 products in the islands, infesting groceries, drugs, and cured and dried 

 products indiscriminately, possibly favoring tobacco in its many man- 

 ufactured forms. At this station it has been most annoying in its 

 injury to the herbarium and specimens of dried fodder plants which 

 had been ground for analysis. It has been bred from cigars, red 

 pepper, and fish guano. Adults have been received from correspond- 

 ents in cigars, in a preparation sold under the name of ••paprika." 

 and in a patented stock food. A local cigar firm recently received a 

 shipment of several thousand cigars from Manila almost ruined by 

 this pest. By taking the proper remedial measures, their storeroom 

 did not become infested. The remedy consisted in fumigating the lot
