INSECTS ATTACKING GARDEN VEGETABLES.

Remedies. — Infested peas should be put into an air-tight box 

 or bin and treated with bi-sulphide of carbon (see p. 10). This 

 fluid is poisonous and inflammable, and must be handled with 

 great care. Its fumes are heavier than air, so that the liquid may 

 be sprinkled over the surface of the peas, or put into an open dish 

 resting on the peas. 



Immersing the infested peas for a minute or two in water 

 heated to 140° Fahrenheit will kill all contained weevils and 

 larvse. 



Kansas Notes. — This insect is commonly injurious all over the 

 State. 



BEAN WEEVIL. 



{Bruchus obtectus Say; Order, Coleoptera.) 



Diagnosis. — Stored beans with a number of small, circular 

 holes, or dark, discolored, circular spots; small weevils (beetles) 

 crawling among the beans. 



Description a7id Life-history. — The adult Bean Weevil much 

 resembles the Pea Weevil, but is little more than one-half as large. 

 It is dark colored, lacking the white spot on the thorax. The life- 

 history is about the same as that of the Pea Weevil, the eggs 



being laid on the young 

 bean pods, of course, in- 

 stead of the pea pods. 

 In the case of the Pea 

 Weevil but one larva 

 enters a pea, while with 

 the Bean Weevil several 

 larvse may find homes in 

 a single bean. When the 

 stored beans are white, 

 the presence of the weevil 

 is easily detected by the 

 dark eye-spot which lies 

 over the cell of one of 

 the enclosed larvse. The
