274 STATE BOARD OF AGRICULTURE. 



The "rose chafer" appears in June, sometimes in immense swarms, and 

 attacks flowers of a great variety and also leaves and blossoms of grapes, often 

 completely ruining the crop. Because of their immense numbers poisons are 

 comparatively ineffective, acting slowly, and the killed specimen being immedi- 

 ately replaced by a new arrival. On grapes two or three days will serve to 

 ruin the crop, and while bordeaux mixture is a repellant to an extent, it must 

 be supplemented by persistent gathering in umbrellas, &c, until the grapes are 

 set or until the brunt of the attack is over. 



" June bugs " occasionally attack fruit blossoms, eating through the stems 

 and causing them to drop ; recently they have done some injury to chestnut, 

 and as these creatures fly after dark protection is less easy. In fact, except in 

 a free use of lime and paris green we have no resource unless the plants are 

 actually covered by a netting, which is, of course, impractical except on a very 

 limited scale.
