I have never observed that the weevils had any choice among varieties, all being subject to their attacks alike, provided all were growing in equally favorable positions.
From observations last year, it would be advisable to remove the straw from one or two rows in order to hasten the maturity of the buds, and keep the straw on the remainder of the patch in order to force the weevils to the uncovered row.
This one crop system could be followed for about two years, when it might be advisable to return to the two crop system if the weevils have disappeared.
Since the weevils do not disperse readily, and since they hibernate within the fields, the one crop system and the plowing up of the beds immediately after picking would probably do away with the injury entirely.
Just above this carrion was a cluster of black and red weevils as large as mice; they hung from a porcupine quill, each tied to it by a thin strand of twisted sinew.

Curiously enough, the chestnut weevils did not go to my chinquapins.
Several kinds of nuts are attacked and injured by long-beaked snout beetles or weevilsbelonging to the genus Balaninus, the chestnut probably being the most seriously damaged.
In the spring, generally about the time cotton begins to form "squares," the weevils shake off their long winter sleep and enter the cotton fields with appetites as sharp as razors.
A second is to kill as many weevils as possible by burning the homes that shelter them in winter.
The weevils can stand a good deal of cold, but fortunately many are killed by winter weather.
Repeat the treatment if any weevils are found alive.
The fumes of this substance are heavy and will pass through the mass of seeds below and kill all the weevils and other animals there.
One is to grow cotton that will mature too early for the weevils to do it much harm.
In this way a good crop can be harvested before the weevils are ready to be most destructive.
The grown weevils try to outlive the cold of winter by hiding snugly away under grass clumps, cotton-stalks, rubbish, or under the bark of trees.

Weevils are the greatest pests, frequently ruining tons of stored corn, wheat, and other cereals.
The weevils are destroyed by birds, the infected bolls and stalks are burnt, millions are killed each winter by cold, other insects prey on them, but at the present time they are one of the greatest pests the south knows.
If you are not equipped to spray, you can reduce weevil injury about 50 percent by jarring the limbs of the trees lightly and gathering the weevils on a sheet during the period of emergence.
Some control of these weevils can be obtained by collecting and destroying the infested nuts before the larvae leave them to enter the soil.
The chestnut weevils are probably the weevilsbest known to most of you.
Begin jarring about the last week in July and confine it to two or three trees until the first weevils appear.
Make the first application when at least six weevils can be jarred onto a sheet on the ground beneath any tree known to have been infested in previous seasons, and make the second 10 to 14 days later.
Most of the small weevils require two years to complete development, and most of the larger weevils but one year.

Illustration: Pitch-eating weevils in the genera Pachylobius, Hylobius, and Pissodes.
Pitch-eating weevilsbreed in the roots of freshly cut stumps.
The most effective control for pine reproduction weevils is to wait nine months before replanting or until the stumps in an area are no longer attractive to the weevil.
Adult weevils are attracted by the odor of fresh pine resin, and quickly invade logging areas.
Emerging adult pitch-eating weevils feed by night on the tender bark of seedlings.
The weevils do not multiply until the squares begin to form.
Postponing the fall destruction of cotton stalks until the middle of December, or later, permitted over 43 per cent of the weevils to survive the winter and attack the next crop.
When the weevils appear on the new cotton in the spring, pick them off and destroy them.
A large majority of the adult weevils also perish in the flames, especially when the stalks are burned after sundown, as weevils retire to the stalk piles for the night at about that time.
Attempts to Destroy Weevils with Poison:= In territory newly infested with the boll weevil, attempts continue to be made to destroy the weevils by poisoning.
Destroy All Punctured Squares:= The weevils that survive the winter are all in the adult stage.
Picking Weevils and Squares The following is the substance of a number of letters from Mississippi farmers relative to picking weevils and squares: Mr. T.
Hibernation:= The immature weevils in the squares and bolls are usually killed during the winter.
Nature has provided a number of agencies to prevent such excessive multiplication; nevertheless, the picking off of a single pair of weevils from the young cotton plants may mean millions less later on.
There is little danger of weevils coming in from other fields until in August, by which time the cotton crop is normally set.
Crawford found 268 weevils the first time; two hundred and fifty the second time, one hundred and ninety-seven the third time and one hundred and fifty the fourth time.
While this treatment probably will not kill all the weevils it will insure a much larger percentage of germination than there would be otherwise.
Any intelligent warfare against the nut weevils calls for a knowledge of these distinctive life histories.
Walnut Husk Maggot Although none of the weevils of the group just discussed attacks walnuts, the fruit of this tree has a serious enemy in the walnut husk maggot.
As with the larger species, a few of the smaller weevils carry as larvae for several years to tide over possible failures of the chestnut crop.
This has resulted in a constant increase of weevils until infestation of the nuts became practically one-hundred per cent.
In the case of the larger weevils the beetles are present only about three months of the year.
In the case of chestnuts, the crop should be harvested as soon as possible after the first nuts fall so that the damage from weevils may be kept at a minimum.
So closely confined are these weevils to their particular food plants that many of them distinguish between the different species of oak and will oviposit only in certain kinds of acorns.
These weevils are to be made the subject of a bulletin by the Bureau of Entomology in the near future, in which it is hoped to go more fully into a discussion of control measures.
In the woods adjacent to the orchard the native chestnut trees are disappearing on account of the blight, and presumably weevils are on the decrease.
Once the chestnut weevils are absent in a locality, there is no chance that oak trees will serve as a means of spreading the weevils back into the locality.
