Excerpt: ... from one field to another is also by flight, and in some instances the carriage of the larvae by water is of importance. CARRIAGE OF LAUV.K IN SEED FOR PLANTING AND OTHER PURPOSES. The transportation of infested seed by man from place to place is the usual means by which this insect is carried to new localities. It was introduced into Mexico in 1911 with seed for planting; into Brazil in 1911-1913 with seed for planting; and more recently into certain parts of Texas with seed in cotton and seed for milling purposes. From what has already been stated concerning the habits of the pink bollworm, it is evident that seed from an infested field is sure to contain a certain percentage of infestation, and it is known that the resting larvae can live for at least 2 years in such seed. It is thus seen that the larvae are admirably adapted for transportation over great distances in this way. Seed, moreover, is often incidentally carried with other products. Railroad cars which have been used for shipping cotton seed are a very dangerous example of this. Seed will usually be found in the cracks and corners and between the walls of the car. Numerous instances of this have been noted, particularly by inspectors at border points, where live pinkbollworm larvae were taken from cars which had been used for seed in the Laguna district and later used for exportation of other products. Bales of cotton often carry seed and as many as several hundred seeds have been found mixed with the lint and attached to the bagging. Cotton waste and used cotton bagging are other items usually having seed attached to them. Cotton pickers in Mexico often move from plantation to plantation. It is a common practice with them to carry their own picking sacks and among their...

Excerpt: ...species of the region except three. The leaves of all species are each tipped with a sharp spine, and the margin of the leaf bears one or more threadlike fibers which frequently strip back and form a loose mat of threads among the bases of the leaves. The margins of the leaves never bear any hooklike spines. In one group of three species that grow in the region of Del Rio, Sanderson, and northward in Texas the leaf margins do not have a threadlike appendage, but are thickened and horny, with very fine teeth, scarcely large enough to be seen by the naked eye, but sharp enough and hard enough to cut the hands badly. Of the other thick-leaved plants of the region the century plants (Agave) all have sharp spines on the ends of the leaves, but the margins bear large recured spines. Sotol (Dasylirion) has flat, strajvshaped leaves with curved, yellow, horny spines on the margin, but they are frayed at the tips. (PI. V, fig. 2.) There are two or three species of Nolina in the region that have long, slim, nearly smooth, but tough leaves, frayed at the tips, without threads or spines, though sometimes a few very small teeth are scattered along the margin. The leaves of these plants are often as thick as they are wide, which is usually not much over one-fourth of an inch, being nearly always triangular, but sometimes nearly circular in cross section. In the region about Marathon and Sanderson, Tex., where one species Nolina erumpenfi) 1 is tolerably abundant, the common name in use'is sacahuista.3 (PI. VIII, fig. 1.) BEAR-GRASS.

Excerpt: ...to changes in the oxygen content of the air was observed until the last day of the experiment. On that day not only water vapor and carbon dioxid, but oxygen also was removed from the system by passing the circulating air through a solution of potassium pyrogallate before returning it to the chamber. This was continued until the proportion of oxygen in the air, which was only 18 per cent at the beginning of the period, was very greatly reduced. After a few hours the circulation of air was stopped and the water vapor and carbon dioxid allowed to ac cumulate in the air of the system in which there was a deficiency of oxygen. The effect on the activity of the bees was soon apparent; the temperature curves, which for some reason had begun to rise, very shortly turned in the opposite direction and continued to fall for about 12 hours. The proportion of oxygen was then 12 per cent and it was thought that the bees had probably been suffocated. Eight hours before the time at which the period would regularly end the air of the system was again put in circulation and water vapor and carbon dioxid removed, oxygen being also removed at the same time. This was continued until the close of the period (which was also the end of the experiment) in order that the air of the system might be quite thoroughly freed of carbon dioxid. After the circulation of air was resumed the bees again indicated that they were living, and during the time that the air-purifying system was operating their activity increased until by the end of the experiment the temperature curve had reached as high a point as at any time during the course of the experiment, even though the proportion of oxygen in the air was low. Analysis of the sample taken at the end of the period showed...

Excerpt: ...fine ones often appearing in midwinter. A publication of this department 1 treats of squab raising for market. There is a great demand for squabs by hotels, restaurants, private hospitals, etc., but their cost is usually too high for them to be used frequently in the ordinary family. The older birds are so seldom eaten in the United States that they are almost a negligible quantity in poultry markets and sell for very low prices. In Europe they are much more commonly used, pigeon pie and potted pigeon being forms in which they are considered especially palatable. DUCKS. Most of the domesticated breeds of ducks have been derived from the wild mallard. Duck breeding has long been practiced in the Old World, where both meat and eggs are in common use, but until recently they were raised in this country only incidentally by farmers who happened to have access to pond or stream. Of late years, however, the duck-raising industry has been greatly developed, with the result that the birds are much improved in size and quality, and are more commonly eateiL than formerly. The egg-laying strains are also attracting attention. Duck flesh is dark throughout and has a distinctive flavor, generally considered palatable. There is a relatively small proportion of flesh to bone, and the meat occurs in such thin, small masses that only four good table portions can be obtained from a medium-sized bird. Specially fattened ducks carve to better advantage, besides having more tender and delicately flavored flesh. Young ducks, usually called ducklings, begin to reach the market in May and may be obtained until January. "Green ducks" is a trade name for those appearing in the spring and early summer. Full-grown birds can be obtained at any season but...

The resistant hybrids, some of which were grafted to vinifera;, comprised Mourvedre X Rupestris 1202, Solonis X Riparia 1616, Berlandieri X Riparia 157.11, Riparia X Rupestris X Aestivalis X Monticola 554.5, Aramon Rupestris Ganzin 1, Riparia Gloire de Montpelier, Rupestris St. George. These vines were planted in the spring of 1914 and inoculated thereafter. On the Muscadine the phylloxera? upon hatching from the eggs refused to settle or feed. The nonresistant varieties were infested throughout summer and autumn, and on their roots the phylloxera; entered into hibernation from September 20 to the beginning of November; in the case of the Champion, they hibernated as late as December 1. On the Catawba and Champion, the most heavily infested, the aphids began hibernation earlier; on the less infested Delaware, Isabella, and Lenoir, somewhat later. Aphids became active about the middle of February, and all hibernants were adult by April 13. This spring activity was somewhat in advance of that occurring in vineyards, but was similar to that which occurred on the caged vinifera vines. On all nonresistant varieties it was observed that the hibernants massed on tuberosities, nodosities, and the normal surface of the roots; and in cracks in a manner similar to that observed to occur on vinifera vines. On the resistant hybrids repeated inoculations during summer and autumn failed to produce more than an extremely light infestation. The phylloxera? settled to hibernate during October, and at the end of that month all were hibernants. They were situated on side rootlets and on the normal surface of the root, but on the Kupestris St. George hibernants occurred also on nodosities which they had caused to form shortly after they...

Excerpt: ...pine seedlings in clumps planted by chipmunks and mice (Douglas fir and lodgepole pine usually occurring singly) may also result in a somewhat larger mortality, since the disturbance which affects one seedling in a clump affects the whole group. Table 8 indicates that as a general thing western yellow pine is less likely to be killed after its third year than is Douglas fir or lodgepole pine. This may be due to the larger size of three-year old yellow pine seedlings. SEASON OF INJURY. To determine the relation between the amount of damage and the time of year when the grazing was done, the plots grazed on the Deadwood allotment in 1913 were grouped into three classes: (a) those grazed early in the season, or up to the latter part of July, which in 1913 was a fairly moist period; (o) those grazed in midseason, from late in July to the middle of August; and (c) those grazed late, or after the middle of August, the driest part of the season. Table 6 shows the relative amount of damage done during each period. Table 6.--Grazing injuries, by time of year, in percentages of number of seedlings on the plots at the time they were grazed. (Dcadwood allotment, 1913.) 'Very small. Injuries which did not result in death, particularly those due to browsing, though insignificant at any season, were greater late in the season than during the earlier period. This is probably due to the drying of the succulent forage of the early part of the season and to the greater liking of sheep for browse types of forage as the season advances. The proportion of seedlings killed by grazing, particularly of those less than a year old, was veTv much greater early in the season than it was later. The reasons for this are that early in summer the seedlings are rather...

Excerpt: ...set of disk nozzles was used in all cases. The chief details and the results of these experiments are recorded in Table XLIII. When reference is made to nicotine sulphate, the commercial article containing 40 per cent of nicotine is intended; likewise references to tobacco extract refer to preparations containing 2.7 per cent of nicotine, or its equivalent. Experiments 5 and 6 of Table XLIV and experiments 5, 6, 7, and 8 of Table XLV are to be considered in connection with Table XLIII. Of these 14 experiments, 5 were directed against the hibernating scales (4 of these in the spring and 1 in the fall); 5 against the loafattached larvae, 2 against the females while making the twigward migration, and 2 against the young females whilo making their maximum growth. These experiments were all negative and showed that nicotine is ineffective against the terrapin scale. COATING SPRAYS. A number of experiments were performed in 1912 with coating sprays, to determine the feasibility of smothering the scale. The chief details and the results of theso experiments are recorded in Table XLIV. The first 4 experiments were made with self-boiled lime-sulphur, 8-8-50, and were applied with coarse nozzles at a pressure of 100 pounds. In experiment 1 the application was made May 24, when 95 per cent of the overwintered scales were mature. This spraying was both extensive and thorough, but was inefficient against the mature females and failed to control the sooty molds. Experiment 2 was directed against the larvae during the beginning of the leafward migration, but gave an efficiency of only 15 per cent and also faded to control sooty molds. In experiment 3 two applications were made, the first at the beginning of the leafward migration and the last when 95...

Department of Agriculture: No; 5 They are deposited mostly in late August and in September, in shallow crevices in the ground, more often among the brace roots of the corn. These eggs hatch the following May and June, and the larvae. Always nearly white in color, attack the roots of the corn and never burrow into the lower stem as does the southern budworm. (see fig. After completing their growth the larvae abandon the corn roots and construct earthen cells in the soil, within which they change to pupae (fig. Which are white like the larvae, and then, during late July and August, to adults or beetles. There is therefore only one genera tion annually. The beetles may perhaps live over winter in extreme southern Texas, but they do not. Do so farther north, where they are of the greatest economic importance.
