JOURNAL FREE ACCESSAmong the cases of scrub typhus newly recognized in Japan after the World War II, those prevalent in the Izu Shichito Islands of Tokyo Prefecture, in Awa-gun, Chiba Prefecture, and in Mt. Fuji area, Shizuoka Prefecture, are called as the "Shichito type scrub typhus" or as the "scutellaris type scrub typhus, " and Trombicula scutellaris has been presumably incriminated as a potential vector of this type of scrub typhus. The study on scrub typhus in Chiba Prefecture was commenced in 1952, when the so called "twentydays fever, " an endemic disease in this Prefecture, was assumed to belong to a scrub typhus by Kasahara et al. (1952) and Kitaoka et al. (1952).View full abstractDownload PDF (1481K) -

JOURNAL FREE ACCESSThe observations of the behavior of the house fly Musca domestica vicina and the lesser house fly Musca domestica vicina and the lesser house fly Fannia canicularis, inhabiting most commonly in houses in Japan, were carried out at inside and outside of a residence in Kawasaki city in winter season of 1958. Their activities showed the diurnal rhythm depending upon the environments surround them, and were found to be correlated mainly with the changes in the air temperature and the light intensity. The flies resting on the ceiling during the night, owing to the low temperature and the low light intensity, began to leave from the resting sites at 11.0〜12.0℃ (M. d. vicina) and 8.4〜10.5℃ at 12〜100lux (F. canicularis) in the morning. And they began to come back to the ceiling again below 9.8℃ or 200lux (M. d. vicina) and 9.8〜11.2℃ or 75lux (F. canicularis). The beginning of the rotary flying of F. canicularis was found at 10.8〜12.4℃ or 12〜800lux. M. d. vicina inhahiting indoors in the morning. in the evening and at night went out often to the sunny place of outdoor in the daytime, while F. canicularis stayed at indoors through a whole day. Their resting sites at night were almost ceiling of room, in which being active in the daytime.View full abstractDownload PDF (923K) -

JOURNAL FREE ACCESSThe bionomics of American cookroach, Periplaneta americana, was investigated in the apartments in Hashima Island, Kyushu, Japan, and the experiments on the control of the roaches by the application of four kinds of insecticides were also done in the same apartments. The results were summarized as follows : In Hashima Island, P. americana was the dominant species of the roaches, the bionomics of which had scarcely been reported in Japan except a few records on the local distribution, and the other species found were P. fuliginosa and Blattella germanica, both of which were far less than P. americana. Male roaches were more abundantly found than the female ones. The roaches were found to be distributed in the apartments not evenly but concentratedly to the particular sections, where kitchinranges would often be used and firewoods and the other materials were disorderly kept under the kitchinranges, or highly moisty. The spray of insecticidal emulsion directly to/or near the hiding places of the roaches were more effective than the coating of the emulsion on the corners or the edges where the roaches would often crawl. The most effective methods were the spray of 1% lindane emulsion and the mixed emulsion of 0.4% dieldrin and 0.6% lindane. The spray of 1% diazinon emulsion was comparatively effective and the effect of 1% BHC suspension was lower than the chemicals stated above. However, about 30 days after the application of any insecticides adopted there, the population of the roaches was found to recover to the level before the application. By the application of the insecticides, the ratio of larvae to all the roaches and that of the male to all adult roaches decreased, probably because of higher susceptibility of larvae than adults and of the male than the female. Thus, it caused the increase of the ratio of female roaches to all the roaches. The fog application of 9.2cc of 0.3% DDVP solution per square meter of floor were practically ineffective to American cockroaches.View full abstractDownload PDF (1253K) -

JOURNAL FREE ACCESSField tests of the control of adult flies, their larvae and mosquito larvae by malathion were done during 1 June to 28 July, 1955, in Yokaichiba, Chiba Prefecture, Japan. The results were summarized as follows : By the spray of 27 to 42cc of 0.5% emulsion or 0.7% kerosene solution of malathion per square meter on the ceilings of the dwellings, the fly population estimated by traps set in dwellings decreased remarkably and the effect lasted for 7 to 10 days. To fly larvae in latrines, the application of 2 liters of 0.1% emulsion or 100g of 1.5% dust of malathion was effective, but the larvae emerged again 7 days after the application. The fly larvae in manure heaps could be controlled by spraying 10 liters of 0.02% malathion emulsion per square meter, though the spray of 2 liters of 0.1% emulsion was almost ineffective. The difference in the effect of applying the same amount of the active ingredient may be ascribed to the permeability of the chemical into the heaps. The application of 100cc of 0.2% malathion emulsion per square meter was effective to mosquito larvae in water tanks or small ponds, though almost ineffective to the pupae of the mosquito.View full abstractDownload PDF (960K) -

JOURNAL FREE ACCESSAttempts were made to clarify some problems of cockroach control in large buildings by means of dry fog-blowing of insecticide. Laboratry-reared adult insects of Blattella germanica Linne and Periplaneta fuliginosa Serville have been introduced into some test-sites. DDVP was only used as test-insecticides. (1) Repeated application tests in which the test insects were confined in a glass ring and placed in each test room showed that the standard amount of the DDVP required for the practical control should be as below : for B. germanica 100ml, per 99cu. meter in a 0.3per cent of oil solution; for P. fuliginosa 200ml., per 99cu. meter in a 0.3per cent of oil solution. (2) It was experimentally confirmed using artificially introduced test-insects that the effect of fogs against the cockroaches inhabiting closed hiding places is difficult to expect, and therefore one should take into consideration that the applied fogs can penetrate into the hiding places by beforehand arrangement. (3) It was also confirmed that the residue after two days showed no effect against German roach. (4) Natural poulation of the cockroaches inhabiting each room of a business building was estimated and the population density and its correlation to the business activity was discussed.View full abstractDownload PDF (674K) -

JOURNAL FREE ACCESSThe authors' intension in the present experiments was to compare the effect of the residues of dieldrin, chlordane, lindane and diazinon to German cockroach, Blattella germanica L., brought into contact for 10 minutes successively, i. e. for 2 minutes once a day in 5 days. The results obtained were summarized that dieldrin and chlordane were equally or slightly more effective in the intermittent contact method than in successive contact method, and, on the contrary, lindane and diazinon were more effective in successive contact method. Based upon the results obtained in the present and previous papers, the authors were led to the conclusion that dieldrin was the most effective and adequate chemical in practical control of German cockroaches by painting the insecticides narrowly on the surface on which the roaches would often crawl.View full abstractDownload PDF (523K) -

JOURNAL FREE ACCESSIn order to ascertain the behavioristic reaction of housefly to certain residues of chlorinated hydrocarbon insecticides, the laboratory tests were made with six strains of housefly, Musca vicina Macq., which had been reared for several months to four years in laboratory. The strains collected from various parts of this country were as follows : DKM (Tokyo), DKE (Ebina, Kanagawa Pref.), DKA (Nase City; Kagoshima Pref.), Aminoko (Aminoko, Amami Islands, Kagoshima Pref.), Kamiaso (Kamiaso, Kanagawa Pref.), and Misaki (Misaki, Kanagawa Pref.). Filter paper containing a given amount of test insecticide (2.5g/m^2 of DDT or 0.25g/m^2 of lindane) was placed in the bottom of the test cage which consisted of net-screen, 15cm in diameter and 5cm in height. Thirty flies were used in each experiment. The flies were allowed to behave freely. During the exposure of five hours, number of flies on the paper and their knocked down rate was counted at 20-minutes intervals. As shown in the results, there were some differences in susceptibility of insecticide among the strains and this phenomenon might due to the differences in physiological resistance among each strain. However, the evidence of a combined physiological and behavioristic resistance in a certain strain was also observed in the present tests. The results have shown that flies of DKM-strain avoided insecticide residues on paper, consequently, lower mortality and higher KT-50 value were obtained. When the flies of this strain were treated topically, they were comparatively susceptible to DDT and lindane.View full abstractDownload PDF (417K) -

JOURNAL FREE ACCESSLaboratory experiments were carried out to compare the effectiveness of diazinon, malathion, lindane, dieldrin and DDT against tropical rat mite, Liponyssus bacoti (Hirst), by the method of spray or contact. The results were summarized as follows : diazinon was the most effective of all the chemicals tested. Malathion came next rank. Lindane was slightly less effective than malathion. Dieldrin and DDT were ineffective to the mite. Considering both on mammalian toxicity and effectiveness to the mite, malathion seemed to be the most suitable chemical for practical control of tropical rat mites.View full abstractDownload PDF (391K) -

JOURNAL FREE ACCESSThe insects crowding on the lamps of living rooms make us very uncomfortable. The authors are attempting to control these insects by using light trap. In the present paper, the authors report the constitution of the insects and their daily fluctuation in numbers, attracted to a light trap situated at the bank of the River Seta, Siga Prefecture, in July 5-6, 1958. In this station, many caddisflies, mayflies and dipterous insects were caught. Their daily fluctuation were shown in Fig 1. Caddisflies were most abundant from sunset to 9 p.m.. Mayflies showed the peak between 9 to 10 p.m. Dipterous insects (chiefly a species of sand-fly) were showed the peak 11 to 12 p.m. The flying activity of these insects seemed to begin from the sunset and to end before the midnight.View full abstractDownload PDF (396K) -
