Mexican Boll-weevil (Anthonomus grandis). — A snout beetle about one-fourth inch in length, which lays its eggs in the squares and bolls, producing a grub which eats out the contents.

Treatment (U. S. Dept. Agric.): —

1.  Destroy the vast majority of weevils in the fall by uprooting and burning the plants. This is the all-important step. It results in the death of millions of weevils. It insures a crop for the following season.

2.  Destroy also many weevils that have survived the preceding operation and are found in the cotton-fields and along the hedgerows, fences, and buildings. This is done by clearing the places referred to thoroughly.

3.  As far as possible, locate the fields in situations where damage will be avoided. This cannot be done in all cases, but can frequently be done to good advantage.

4.  Prepare the land early and thoroughly in order to obtain an early crop. This means fall plowing and winter working of the land.

5.    Provide wide rows, and plenty of space between the rows and the plants in the drill, for the assistance of the natural enemies of the weevil, which do more against the pest than the farmer can do himself by any known means. Check-rowing, wherever practicable, is an excellent practice.

6.    Insure an early crop by early planting of early-maturing varieties, and by fertilizing where necessary.

7.  Continue the procuring of an early crop by early chopping to a stand and early and frequent cultivation. Do not lose the fruit the plants have set by cultivation too deep or too close to the rows.

8.  Where the labor is sufficient, pick the first appearing weevils and the first infested squares. Do not destroy the squares, but place them in screened cages. By this means the escape of the weevils will be prevented, while the parasites will be able to escape to continue their assistance on the side of the farmer.

9.  Use a crossbar of iron or wood, or some similar device, to cause the infested squares to fall early to the ground, so that they will be exposed to the important effects of heat and parasites.

10. Do not poison for the leaf-worm unless its work begins at an abnormally early date in the summer. Cranberry. Fruit-worm (Mineola vaccinii).—Small caterpillar working in the fruits, eating out the insides.

Preventive. — For bogs with abundant water, reflow for ten days immediately after picking. Let the foliage ripen, and then turn on water for winter. Draw off water early in April, and every third or fourth year hold it on until the middle of May. For dry bogs spray three times with arsenate of lead during July. Bury all screenings. Fire-worm, Cranberry-worm, or Black-headed Cranberry-worm (Eudemis vacciniana). — Small larva, green, black-headed, feeding upon the shoots and young leaves, drawing them together by silken threads ; two broods.

Treatment. — Flooding for two or three days when the worms come down to pupate. Arsenicals. Yellow-headed Cranberry-worm (Acleris minuta). — Stout, yellowish-green, small caterpillar, with a yellow head, webbing up the leaves as it works.

Treatment. — Hold the water late on the bog in spring to prevent egg-laying. Arsenicals from the middle of May till July 1. Cranberry-girdler (Crambus hortuellus). — Small caterpillars feeding on the stems just beneath the surface of the sand.

Preventive. — Reflow just after picking, for a week or ten days, or reflow for a day or two about June 10.

False Army-worm (Calocampa nupera).— Green to blackish caterpillars devouring the leaves and buds.

Treatment. — Reflow for from twenty-four to thirty-six hours soon after the middle of May. It may be necessary to reflow a second time. Destroy all caterpillars washed ashore while the water is on.

In dry bogs, spray early in May with arsenate of lead. Cucumber. Pickle-worm (Diaphania nitidalis). — Larva, about an inch long, yellowish white, tinged with green, boring into cucumbers; two broods.

Preventives. — Clean farming, fall plowing, and rotation of crops.

Remedies. — Kill the caterpillars before they enter the fruit by spraying with arsenate of lead about the time the buds begin to form, and repeat in two weeks. Stem-borer. — See under Squash (p. 331), where it is described as root-borer. Melon-worm. — See under Melon, p. 322.

Spotted Cucumber-beetle (Diabrotica 12-punctata).— Beetle, yellowish and black spotted, about one-fourth inch long, feeding upon the leaves and fruit. Sometimes attacks fruit-trees, and the larva may injure roots of corn.

Treatment. — Same as for Striped Cucumber-beetle, below.
