For the control of cutworms, poisoned bait prepared according to 

 the Kansas formula is recommended. Cultural operations carried 

 out well in advance of the crop will destroy pupae in the soil. The 

 tobacco horn worm (Protoparce) can be controlled by the application 

 of a mixture of Paris green and lime in equal parts or one part Paris 

 green to three or four parts of lime. Against the larvae of flea-beetles, 

 attacking the roots of seedlings, a strong solution of lead arsenate 

 (1 lb. in 12-16 gals, water) is effective. The cigarette beetle, Lasioderma 

 serricorne, which attacks stored tobacco, is controlled by fumigation 

 with carbon bisulphide, allowing 4 lb, to 1,000 cubic feet for an 

 exposure of 48 hours.

Lachnosterna pairuelis (brown hard-back) occurs in St. Kitts as a 

 pest of sugar-cane. It is believed to be of importance as a root feeder 

 and may be connected with attacks of root fungus. The larvae are 

 attacked by a Hymenopterous parasite. In Antigua a species of 

 Lachnosterna frequently causes serious injury to sugar-cane and has 

 also been recorded on onions and maize. The roots and bases of the 

 stems of both young and ripening plants are attacked. Related insects, 

 occur in other islands, including Phytalus smithi in Barbados and 

 Mauritius, Strategics titanus in St. Croix and Porto Rico, and Ligyrus- 

 iumulosus throughout the West Indies. L. rugiceps is a pest of sugar- 

 cane and maize in the southern United States ; S. anachoretus attacks 

 coconuts and sugar-cane in Trinidad, and Dycinetus barbatus is believed 

 to injure crops in Barbuda. In addition to the control exercised over 

 hard-back larvae by natural enemies, of which the Scoliid wasp, Tiphia 

 •parallela, is the most important, and the use of poisoned bait, the 

 control of the insects depends on the collection of larvae and adults 

 and purely agricultural methods.
