INJURIOUS INSECTS 1 35 



in Fig. 45, b. It measures, when extended, three- 

 tenths of an inch, being of about the same proportions 

 as the lar\'a of the common species, but is readily sep- 

 arable by its ochraceous orange color. Fig. 45, c, 

 shows the second abdominal segment of lan'a, and d 

 same of the common asparagus beetle, much enlarged. 

 Remedies. — The remedies are those indicated for 

 the common asparagus beetle, with the possible excep- 

 tion of caustic lime and other measures that are 

 diredled solely against that species, but the habit of 

 the lar^-a of living within the berry places it for that 

 period beyond the reach of insecticides. The collec- 

 tion and destruction of the asparagus berries before 

 ripening might be a solution of the problem,. but it is 

 questionable if recourse to this measure would be 

 necessar}', save in cases of an exceptional abundance 

 of the insect. 



THE ASPARAGUS MINER 

 {Agrontyza simplex) 



In a recent bulletin from the New York Experi- 

 ment Station, Prof. F. A. Sirrine describes a com- 

 paratively new and injurious insedl on asparagus. It 

 was discovered on Long Island, and injures the young 

 plants by mining just underneath the outside surface. 

 The habits of this creature are such that there is little 

 chance of apph'ing remedies for its destruction. Cul- 

 tural and preventive measures seem to be the most 

 practical, and are suggested. The parent insedl is a 

 small fly, which deposits its eggs for the first brood 

 earl}' in June, and no doubt much can be done toward 

 keeping the pest under control b}' not allowing small 

 shoots to grow during the cutting season. Professor
