INJURIOUS INSECTS OF KANSAS, 



care must be takeu that no lighted lamps, cigars or burning ma- 

 terial shall come near the bi-sulphide of carbon, or near places 

 where it has been used, until the odor has passed entirely away . 

 The liquid is highly inflammable and explosive. No danger, 

 however, need exist if proper care be taken. Grain treated with 

 bi-sulphide of carbon is not injured at all by the insecticide. The 

 bad odor passes off in a few days. 



Kansas Notes. — In a bulletin issued by this Department in 

 February, 1892, attention is called to the occurrence of this pest 

 in Kansas. At this writing (October, 1892), this insect is threat- 

 ening to injure the cereal specimens collected by the State for ex- 

 hibit at the World's Fair. The specimens are stored in a large 

 warehouse at Topeka, in which the moths are abundant. The 

 pest does great damage in the Southern States, where as many 

 as eight generations are produced in a j^ear. 



GRAIN WEEVILS. 

 {Calandria species; Order, Coleoptera.) 



Diagnosis. — About same as for Grain Moth. A footless grub ; 



pupa without long feelers, or adult beetle, instead of moth will be 



found within the kernels. 



Description and Life-history. — The adult insect is a small, dark- 

 colored snout-beetle, 

 which lays its eggs on the 

 grain. The small, foot- 

 less larvae soon hatch and 

 eat their way into the 

 kernels, maturing in a 

 few weeks. There are 

 several broods each year. 

 Corn, oats, wheat, barley 

 and other stored grains 

 are indiscriminately at- 

 tacked. 



Remedies. — Same as 



Fk;. 25. Grain Weevil; a, adult; b, larva; p /-> • "^T aI, 



c, pupa, all enlarged. lOr Ijrain iViOtn.
