Excerpt: ...effect of wind upon the results is so marked that fumigation should not be attempted with anything stronger than a slight breeze, particularly if the tents have not been rendered gas-tight or nearly so by the use of a "filler." It has been found, with an untreated tent, that with a dosage sufficient to destroy 100 per cent of white fly pupae, a brisk breeze renders the results so uncertain that the effectiveness may be as low as 30 per cent in some sections of the tree, while in others the destruction of the insect may be complete. Atmospheric humidity and dews.--The presence of moisture in the form of dew does not seem to have any deleterious effect upon the foliage, although in California it is generally considered necessary to materially increase the dosage in such cases to insure the effectiveness of the work against scale insects. Prof. H. A. Gossard " concluded that "moisture did not seem to interfere with the efficiency of the work, unless the leaves were almost dripping, when it became a factor of much disturbance, though not as great as we had thought probable." The experiments conducted by the writer and assistants.during January and February, 1907, show that moisture on the foliage during the period of exposure has no marked effect on the foliage or upon the efficiency of the gas against the white fly. In the six instances where the leaves were wet with dew, examination showed that 100 per cent of the insects were destroyed in all cases but one, and in this only a single specimen out of 102 under observation, before and after fumigation, survived the treatment. The results of the tests concerning the effect of atmospheric moisture on the efficiencv of the fumigation treatment are given in Table! Table...

Excerpt: ...summer, brushed, and, if necessary, exposed to the sunlight. It would be more convenient, however, to so inclose or wrap up such material as to prevent the access of the moths to it, after it has once been thoroughly treated and aired. This can be easily effected in the case of clothing and furs by wrapping them up tightly in stout paper, or inclosing in well-made bags of cotton or linen cloth or strong paper. Dr. Howard has adopted a plan which is inexpensive and which he has found eminently satisfactory. For a small sum he secured a number of the large pasteboard boxes such as tailors use, and in these packs away all winter clothing, gumming a strip of wrapping paper around the edge, so as to seal up the box completely and leave no cracks. These boxes with care will last many years. With thorough preliminary treatment it will not be necessary to use the tar-impregnated paper sacks sold as moth protectors, which may be objectionable on account of the odor. The method of protection adopted by one of the leading furriers of Washington, who also has a large business and experience in storing costly furs, etc., is practically the course already outlined. Furs, etc., when received are first most thoroughly and vigorously beaten with small sticks, to dislodge all loosened hair and the larvae or moths. They are then gone over carefully with a steel comb and packed away in large boxes lined with heavy tar rooting paper, or in closets similarly lined with this paper. An examination is made every two to four weeks, and, if necessary at any time, any garment requiring it is rebeaten and combed. During many years of experience in this climate, which is especially favorable to moth damage, this merchant has prevented any serious injury from moths. A...

LIFE HISTORY. " Observations on the biology of this species have been made by Hunter and Hooker (1907), Hooker (1909), Rohr (1909), and New .-', --2 _-.-. _. 3 _ FIG. 12.--The Cayenne tick, Amblyomma CGj8'I17l7L8(.'.' Distribution in North and Central America. The large dots show localities where the species has been collected in our investigation. The small dots indicate the probable range of the species. (0riginal.) The egg (Table LXVII).--In the laboratory in August, at a mean temperature of 84 F., oviposition commenced on the ninth day following dropping while out of doors, at a mean temperature of 84 F., 11 days passed. Eight of 10 females collected April 22, 1908, and kept in the laboratory at a mean temperature of 63 F. commenced oviposition on the eighteenth day, the other two beginning oviposition on the sixteenth and twentieth days after collection. The average preoviposition period for 13 ticks was 16.5 days and the average oviposition period was 19.7 days. In the laboratory in May, at a mean temperature of 77 F. oviposition continued for as long as 23 days. The largest number of eggs recorded was 4,789, which were deposited in the laboratory in 20 days following May 10, 1908. The largest number of eggs deposited in 1 day was 447. The average number of eggs deposited, based upon records of 13 ticks, is 3,536. All of the females used in these counts were collected individuals and may not have been completely engorged. Newstead states that Worthly has found 7,240 eggs to be deposited by an individual of this species and Rohr records 7,742 from 1 specimen. The minimum incubation period in the laboratory at a mean temperature of 80 F. was 37 days. Out of doors, at a mean temperature...

Excerpt: ...a number of laboratory experiments bearing directly upon the treatment of foul brood. His object was to determine the antiseptic value of various drugs for this species. The results obtained by this method of testing the antiseptic value were reported for weak solutions of salicylic acid, camphor, thymol, carbolic acid and tar, creolin, eucalyptus, beta naphthol, naphthalene, and formic acid. In doing this the drug to be tested was added to agar. The agar was inoculated with a pure culture of the organism, and observations were made as to whether a growth took place on this medicated medium. Harrison gives the results of experiments in which he used two colonies of bees to test the value of naphthol and formic acid in the treatment of foul brood. The results which he obtained, however, can have only a relative value in treatment, since the organism with which he worked has most likely no etiological relation to any disease, or at least an unimportant one. Harrison had reached the conclusion that considerable attenuation in cultures of B. alvei may take place by its prolonged growth on artificial media. Since old cultures on this ground might be objectionable, he used, in his experimental inoculation, cultures which were only three generations from the diseased larvae. The further technique, in the carrying out of hia experiment, involved the feeding of the spores from cultures to each of two healthy swarms placed side by side. The spores were scraped from the surface of an agar slant, put into 10 cc. of water, and well shaken. This suspension was then poured into medicated sirup. One colony was fed sirup containing the spores of B. alvei and one-third of a grain of beta naphthol to 1 liter of the sirup. The other colony was fed sirup...
