INJURIOUS INSECTS 



MAY BEETLK <>i; JUNE BUG. (Lacltn<mt<-nm 

 Frohl. ; order Coleoptera.) A large familiar brown 

 beetle, frequently heard buzzing about lamps at night. 

 Feeds upon leaves of several varieties of trees. The 

 common white grub, found when turning the soil, is the 

 larval stage of this beetle. This grub frequently dam- 

 ages strawberries. 



Ecini'dics. Use arsenites for beetle, and grubby 

 plots can be freed by plowing to expose the grubs to 

 poultry and field birds. The hogs will likewise clear 

 the ground. Do not plant strawberries in land where 

 these grubs are abundant. 



MEALY-BUGS. (Dactylopius adonidum Linn.; order 

 Hemiptera.) White scale insects, which feed upon 

 greenhouse plants. 



Remedies. A small stream of water generally drives 

 them away from greenhouse plants. House plants may 

 be washed in soapsuds or the insects can be removed 

 from tender plants with an old toothbrush. 



Maple. MAPLE WORM. See under Green Striped 

 Maple Worm. 



FALL WEB WORM. (Hyphantria cunea Drury; 

 order Lepidoptera.) Caterpillars feeding in swarms 

 within large webs in late summer and early fall. Re- 

 move the web-infested limbs, and burn or crush the 

 worms thereon. If it is objectionable to remove the 

 infested limbs, spray the populous web thoroughly with 

 kerosene emulsion.
