INSECTS INJURIOUS TO MELONS, CUCUMBERS, ETC. 351 



quarters, hibernating along the edge of woodlands, beneath leaves, 

 under logs, boards or whatever shelter may be available. In 

 the South there are probably two or three broods a year accord- 

 ing to the latitude. 



Control. The eggs are easily seen and should be picked off 

 and destroyed. The adults cannot be killed by insecticides, but 

 the nymphs may be destroyed by spraying with kerosene emulsion, 

 or a mixture of " Black-leaf 40, " one to 400 with soap. The 

 adult bugs may be readily trapped by placing small pieces of 

 board or similar shelter near the vines, under which they will 

 hide at night and from which they may be gathered in the early 

 morning. Cucumbers and melons may be protected by planting 

 early squash among them, as the bugs prefer the squash, from 

 which they may be collected. Cleaning up the vines in the fall 

 is evidently of importance in reducing the number which will 

 hibernate 



The Squash Ladybird * 



Although almost all of the ladybird beetles are exceedingly 

 beneficial, this species, with its near relative the bean-ladybird 



are the exceptions which prove the rule, being the only injurious 

 forms with which we have to contend. Both the beetles and larvae 

 feed on the foliage of various cucurbs, but prefer that of the squash. 

 It is an Eastern species, not being injurious west of the Mississippi
