two rows of triangular Telvet3M:)lack spots extending down the back. 

 Four or five broods a 3-ear occur in Texas. By picking them off of 

 young cotton when chopping in the spring they may be largely con- 

 trolled. As they pupate in 

 the soil, frequent cultiva- 

 tions destroy the pupae. 



COTTON STAINER.i 



The cotton stainer (fig. 24) 

 is important onl}^ in the 

 Southeast, especially in 

 Florida. It is a sucking bug 

 with a long beak. The body 

 is red, with dark-brown or 

 black wings. It feeds on the 

 juices of many plants. The 

 young are similar to the 

 adult except that thewings 

 are not developed. Much 

 injury is done to cotton by the staining of the fiber. In sections 

 where this bug is abundant, measures should be taken to hold down 



the growth of weeds, 

 upon which the 

 stainer breeds in great 

 numbers. Principal 

 among these weeds 

 are Spanish cockle- 

 bur- and nightshade.^ 

 They may be trapp(Ml 

 by placing small 

 bunches of cotton 

 seed in different parts 

 of the field. 



As soon as the 

 young bugs make 

 their appearance in 

 the spring, the 

 colonies should be 

 sprayed with kero- 

 sene emulsion, or jarred into buckets of water having a film of 

 kerosene.
