PE.\ ^^■EEVIL. ^ '*'^- ^ 



Seed peas often may be 

 found with a single round hole 

 in each, due to attack by the 

 pea weevil (fig. 58), or "pea 

 bug," a beetle measuring about 

 one-fourth of an inch in length. 

 While this insect is black in 

 ground color,. it is thickly cov- 

 ered with a brownish fuzz, with black and white markings. It is a 

 ]:)est of long standing in this country. On account of its ravages, 



seed peas are largely im- 

 ported from Canada and the 

 extreme northern States. 

 Every pea in a pod when 

 ready for the table often is 

 infested with this weevil.

seed, however, the cell in- 

 habited by the insect is quite plainly seen under the skin. Many 

 weeviled seeds germinate, but they arer' likely to be weak and non- 

 productive. Since this species prodi:ices only one 

 generation a year, it is more readily treated than 

 are the bean and cowpea weevils. 



Control. — Keep seed peas in a warm room, in 

 a tight bag or box, one full season beforeplanting. // imarajfii™ \ y 



The weevils will issue from the seed and die. Plant 

 late in order to secure sound seed stock. Fumi- 

 gate with carbon disulphid. (See Farmers' Bulle- 

 tin 799.) Do not plant weeviled or " buggy " peas, 

 as it will not pay.

The 4-spotted bean weevil (fig. 59) and the 

 cowpea weevil (fig. 60) resemble each other rather 

 closely. While both favor cowpeas as food, they also live on table 

 beans in the South — peas, chickpeas, and, in fact, all leguminous
