The Bean Weevil (Bruchus obtectus Say). — These are small beetles 

 which resemble the Pea weevil in shape but are only half its size. They 

 breed in both green and dried beans, and when common are extremely 

 destructive. They were reported over a year ago near Huntingdon in Dutch 

 beans. Descendants of specimens received at that time have been breeding 

 in dried beans in the laboratory ever since. The eggs are laid in the field 

 on the young pods or inserted through a slit cut between the two halves of 

 the pod. The grubs from the eggs laid on the pod eat their way to the inte- 

 rior, feeding a short time on the substance of the pod, and then enter the 

 seeds. Those from eggs laid within the pods seem to attack the seeds at

once. Several grubs will be found in a seed, within which they pass their 

 transformations. They may emerge in the fall or at any time during the 

 winter. If the place where the beans are kept is at all warm the beetles 

 lay eggs upon the dried beans, or cutting a slit between the seed-leaves 

 insert their eggs. The grubs which hatch bore into and feed upon the 

 seeds, eventually completely riddling them, even reducing them finally to 

 shells and dried powder. I have taken twenty-four adults and young from 

 one dried bean. The eggs laid on dried beans in the laboratory hatched 

 in two weeks (average). The greater number were laid on the skin. The 

 larvae wandered about on the bean for a short time, sometimes several 

 hours, and finally entered through any abrasion in the skin or cut a round 

 hole through any part. For a short time fine dust was extruded from the 

 burrow. The pupae appeared in about five weeks from the hatching of the 

 eggs, and the adults eight days later. 



The one safe method of control is to gather the crop carefully and 

 fumigate (as for the pea- weevil) immediately.

 the common "white butterfly" are always plentiful on cabbages and 

 allied crops. They breed throughout the season ; many caterpillars were
