able to find a breeding place would serve to liberate another generation 
of weevils, possibly in June, and these would produce another generation 
extending through July and August, and these weevils would infest the 
ripening crop. 
The writer is convinced that statements like the following “The 
adult weevil comes from the seed bean or pea, we plant, so by treating 
the seed or planting clean seed we need never be bothered.” 1 or “—when 9 
one uses ‘buggy’ seed in which the pests are alive, one places the insect 
in just the best surroundings for their continued welfare;” cannot be 
applied to Bruchus obtectus Say, or B. quadrimaculatus Fab. 
Conclusions 
The planting of weevily beans or cowpeas injures the crop (1) by the 
injury of the germs causing a large percentage of the seeds to fail to 
germinate (2) by accelerating decomposition of the seeds while they are 
germinating (3) by holding the cotyledons together thus preventing the 
development of the primary leaves and (4) by removing and making 
unavailable much of the plant food which should aid the young plant in 
becoming well established thus making weak unproductive plants. 
The planting of weevily beans does not appear to have any bearing 
on the weevil infestation of the new crop.
