ed or elongated in shape; whitish or pale 

 yellow in color with a large tuft of white 

 flocculence covering the posterior end of 

 the body. The legs, antennae, and spots 

 on the top of the head are brown. The 

 winged lice are a little larger, more elon- 

 gated and much darker in color. The 

 head, antennae, legs and thorax are black 

 and being usually covered with a fine, 

 white powder appear bluish-black; ab- 

 domen dark green. The presence of this 

 pest is easily told by the white floccu- 

 lence which covers the lice as well as sur- 

 rounding infested areas on the roots. 



Food Plants 



As this is a subterranean aphid, only 

 the roots are affected, but often in such 

 a way as to ruin portions of the crop. 

 Sugar beets are the only economic plants 

 attacked to any injurious degree. Wild 

 yarrow, dock, knotweed (Polygonum avi- 

 ciilare) are also attacked. 



Remedy 

 Rotation.

 Blister Beetles 



The striped blister beetle or what is 

 sometimes called the old-fashioned potato 

 beetle, frequently attacks the beet. They 

 come in immense numbers and are likely 

 to do serious injury before their presence 

 is observed. They are long, slender 

 beetles with black and yellow stripes. 

 Apply arsenate of lead as soon as the 

 beetles appear.

Minute False Chinch Bug 



Nysius angustatus minutus Uhl. 

 Family Lygaeidae 

 General Appearance 

 The adults are very small grayish- 

 brown bugs, about one-sixteenth of an 

 inch long. The young are somewhat 

 lighter in color, having reddish-brown 

 abdomens and lacking wings. The legs 

 and antennae appear very long and are 

 dark. 



Life History 

 The eggs are deposited in the spring 

 and early summer by the adults which 

 have hibernated during the winter. The 

 young are dull gray or brownish-red, and 

 collect in great numbers upon the host 

 plants. The life cycle is short, there be- 

 ing many successive broods each year. 



Food Plants 



The insect is especially destructive to 

 sugar beets grown for seed. It has been 

 collected in large numbers on cultivated 

 flowers. 



Control 

 Soap emulsions and tobacco sprays are 

 excellent remedies. Pyrethrum is also 

 recommended, but is too expensive for 

 large plantings.
