Thus the grain will not be able to heat quickly, but, being cooled by the wind, keeps a long time. Other exposures produce the corn weevil and the other little creatures that are wont to spoil the grain.
Our pathologists will find immune varieties that will resist the root disease, and the bollworm can be dealt with, but the boll weevil is a serious menace to the cotton crop. It is a Central American insect that has become acclimated in Texas and has done great damage.
When the full season for planting cotton had come it was discovered that so many farmers had planted cotton that the plan of co-operation was a failure, and the whole district went back to cotton, with full prospect of assisting the boll weevil in his course toward the East. The reasons for this action lie in the type of farmer who thus found it impossible to co-operate.
LXIII. Grain is taken out of store to be cleaned, when the weevil begins to damage it. When this is apparent the grain should be laid out in the sun and bowls of water placed nearby and the weevil will swarm on this water and drown themselves.
Present her with a Cleonus of a different species, or any other large Weevil, of a sort which she has most probably never seen before, since it does not figure on the inventory of the provisions in her burrows. This time there is no show of disdain: the victim is seized and stabbed in the regulation manner and forthwith stored away.
Great progress has already been made among farmers by the creation of farmers' institutes, of dairy associations, of breeders' associations, horticultural associations, and the like. A striking example of how the Government and the farmers can cooperate is shown in connection with the menace offered to the cotton growers of the Southern States by the advance of the boll weevil.
I showed myself a ready pupil to my masters' teaching and used to paralyze a Buprestis or a Weevil almost as well as a Cerceris could have done. Why should I not to-day imitate that expert butcher, the Tarantula? With the point of a fine needle, I inject a tiny drop of ammonia at the base of the skull of a Carpenter-bee or a Grasshopper.
How can I keep certain insects from getting into my dry beans? I have finished picking the crop. Every year a little, short, stubby beetle gets in them before spring and makes them unfit for use. You have to do with the bean weevil. The eggs are inserted by the insect while the beans are still green in the pods; subsequently the eggs hatch and the worm excavates the interior of the ripened beans.
The pea, the broad bean, the vetch, and the chick-pea all have their vermin; but the haricot, lou gounflo-gus, never. What should we do, poor folk as we are, if the Courcoussoun robbed us of it?" The fact is that the weevil despises the haricot; a very curious dislike if we consider how industriously the other vegetables of the same family are attacked.
During the first week of August, when the mature Bruchus begins to emerge, I notice a little Chalcidian, the protector of our peas. In my rearing-cages it issues under my eyes in abundance from the peas infested by the grub of the weevil. The female has a reddish head and thorax; the abdomen is black, with a long augur-like oviscapt. The male, a little smaller, is black.
