radish and })r()l)ahly also infest the radish. Serious injury to 

 cab})age and cauliflower plants in the hot-bed has been re- 

 ported from IVIissouri. The beetles, however, prefer to deposit 

 their eggs in the stems of wild pepper-grass, hedge mustard and 

 shepherd's purse. When these plants are available for egg- 

 laying, cultivated crops are not usually infested. In case wild 

 plants are allowed to grow as a trap crop, they should be de- 

 stroyed before the larviie reach maturity else they will merely 

 serve to increase the abundance of the pest.

The Cabbage Seed-Stalk Weevil 



Ceutorhynchiis quadridens Panzer 



Another European weevil closely related to the one last 

 treated has been introduced into INIassachusetts and Long

 serious pest to cabbage grown for seed, hundreds of larvie 

 being found in a single stalk, their presence causing the plants 

 to wilt and break over just before the seed begins to mature. 

 Whole fields are often ruined in this way. The adult is slightly 

 smaller than the cabbage curculio and the scales with which 

 the body is covered are white intermixed with gray hairs. This 

 weevil also infests kale and turnip and in Europe it is recorded 

 as breeding in mustard, water cress, horse-radish and rape. 



No satisfactory method of controlling this insect is known.
