=Rate of Increase:= The weevils that survive the winter begin to lay eggs when the first squares form on the cotton and successive broods continue to lay eggs until checked by heavy or killing frost in the late fall. Observations made by Drs. W. D. Hunter and W. E. Hinds, show that the female weevil deposits eggs at the rate of from three to five per day and continues to lay eggs for an average of twenty-eight days. The following is a quotation from Dr. W. D. Hunter, government entomologist in charge of the boll weevil work in the South: "A conservative estimate of the possible progeny of a single pair of weevils during the season beginning on June 20 and extending to November 4 is 12,755,000." [Illustration: Larvae of boll weevil in cotton square] =Life Period of Weevil:= Weevils born during the early summer live from fifty to seventy-five days. Weevils that are born late in the fall hibernate and large numbers live through the winter and for about twenty days after emerging in the spring. =Hibernation:= The immature weevils in the squares and bolls are usually killed during the winter. All adult weevils become dormant and the well protected weevils usually live through the winter and do great damage in the spring. The adult weevil spends the winter in hedges, broomsedge, woods, hay stacks, farm buildings, decayed logs, moss and dead trees. Rotation of Crops A Safe and Sane System of Crop Rotation in Boll Weevil Territory Absolutely Necessary When the boll weevil first appears in a territory, the first efforts at breaking away from all cotton usually consist in going largely into another single crop system of farming rather than the production of a variety of crops. The evils of the new system are usually as great as those of the all cotton system. Many farmers rush into the truck business. Of course, truck crops should be grown on every farm in the weevil territory, and, in some particular localities, they may constitute the main reliance for cash, but it seems that the truck business is a gamble for the average cotton farmer. Trucking has lured many a farmer to financial ruin. The crop rotation for the average cotton farmer should include oats, corn, some cotton, and at least one leguminous crop. Along with this should go the growing of hogs, mules, horses and cattle instead of having to buy them from other sections of the country. It is not possible for the farmer in the boll weevil territory to entirely supplant cotton as a money crop, but this crop should be supplemented with the growing of home supplies, as well as other crops which will produce cash returns.
