help to kill off the worms, for this reason, all worms that are collected 

 should be placed in tight enclosures, with the open bottoms set into 

 the soil and with openings at the tops covered with screening or net- 

 ting, having a large enough mesh to allow for the exit of the Hies, but 

 not large enough to permit the escape of the millers or moths which 

 come forth from the unparasitized worms. 



LITTLE GRAIN-MOTH. 



(Tinia granella.) 



A small moth that bores Into seeds and grains, working both In the field and In stored 

 grains. 



To the list of Tiniid moths working in grain in our state we must 

 add one more, the little grain-moth or wolf-moth of Europe. It is 

 very small, only about the size of a clothes-moth, but differing in having 

 spotted wings. The ground color is creamy white with a suggestion 

 of pearl, the wings being marked by brown or blackish spots. There is 

 a tuft of pure white scales at the front of the head. The insect measures 

 a little less than a fourth of an inch when the wings are folded. In 

 its work it resembles the Angoumois grain-moth to a decree, tunneling 



into the kernel of grain of 

 all sorts and binding thorn 

 together Avith webs of silk. 

 The larvae also crawl about 

 more or less aimlessly, spin- 

 ning threads wherever they 

 go and thus fouling more 

 than they eat. The eggs are.

in the cob, where it was 

 the cause of severe losses. We have received it also from Mr. E. J. 

 Kraus, of Lansing, who bred the moths from larvae found tunneling 

 in corn-stalks which had been stored in a barn over winter. The de- 

 termination in both cases was verified by Mr. F. H. Chittenden of our 

 National Bureau of Entomology. We have also bred what appears to 

 be the same species from drying fungi (Morchella) here at the Agri- 

 cultural College. 



REMEDIES. 



The habits of this pest render it diflicult to eradicate, but fortunately 

 it is not so very widespread as yet. No better remedy suggests itself 

 than that recommended for the Angoumois grain-moth — fumigation with 

 carbon-bisulphide or possibly with some other agent.
