attack plants such as the potato as soon as these plants 

 appear above-ground. Upon these they lay egg's which 

 bring forth reddish, sing-like larv;r. This brood of 

 larvne is the one which frequently defoliates the first 

 crop of potatoes. Before the application of arsenites 

 was fully understood, the potato beetle was an enemy 

 of considerable importance. In those days the only 

 means of ridding the potato patch was by hand-picking 

 the eggs and insects. With a more complete knowledge 

 of insecticides, however, we find little or no difficulty 

 in treating the potato plants by spraying with Paris 

 green one pound, freshly slaked lime one pound, water 

 100 gallons. 



Squash-Bug. -In garden crops the squash-bug and 

 the cabbage worm are frequently injurious. The 

 squash-bug 1 attacks and causes 

 considerable injury to the vines 

 of the cucumber. This dull, 

 grayish-brown insect belongs to 

 the order Hemiptera, suborder 

 lleteroptera, and therefore has 

 sucking mouth-parts. The punc- 

 ture made b the beak of this 



insect when feeding seems to be FIO.IU. squash-bug 



tristis). Drawn from nature, by 



peculiarly poisonous, especially MISS M. E. wise. x2. 

 to young vines. The insect spends the winter as an adult, 

 and in the spring lays its golden-brown eggs upon the 

 vines of the squash or cucumber family. These insects. 

 as has been previously said, secure nourishment from 

 within the plant, and therefore cannot be poisoned by ar- 



Mstis.
