JOURNAL FREE ACCESSStudy on distribution of oribatid mites as a vectors of Anoplocephaline cestodes, containing Moniezia expansa, was made. Soil samples were collected in winter at pastures, mainly of livestock breeding farm in each prefecture of Japan. Thirteen families, 19 genera, 31 species and 1877 individuals of oribatid mites were extracted by means of a Tullgren apparatus (Table 1). A naverage, 3.0 species are found in one soil sample and it means that the oribatid fauna of pasture soils are much simple as compaired with woodland one (Fig.1). Scheloribates rigidisetosus Willm. and Trichogalumna lunai Bal. are considered most dominant and show constant number among 41 samples collected. (Table 4 and 5). Their percentage, however, vary considerably in each sample (Fig.2). Scheloribates laevigatus (Koch) comes after them. This species are already known as a vector of Moniezia expansa and a mite of wide distribution. Mites belonging to the family Phthiracaridae may be reduced in pasture soils, while they are more abundant in other circumstances.View full abstractDownload PDF (628K) -

JOURNAL FREE ACCESSExperimental studies were made to observe the mode of breeding of the common grain mite, Tyrophagus dimidiatus, in various stored food products. Fourty five kinds of samples were kept separately in glass chambers under the temperature of 25℃ and the relative humidity of 75%, in which contain equal amount of the mite samples and the numbers of mite per gramm were counted with the saturated saline floatation method at the interval of a month for three times. At the observation made one month after the start of the cultures, the highest mite count of 34, 000 per gramm was seen in white cheese, which were followed by other cheese samples, dried yeast, laboratory animal food powder, rice bran, various grains, and so on. At the observations of two and three months later, considerable changes in the order of the mite counts were seen by the samples; in "sake-kasu" (rice-wine lees) for example, a retarded breeding of the mite was seen with the highest count of 167, 000 per gram after three months of culture. In most samples, the population were seen to increase by months but in some others the highest population observed at the first or second month.View full abstractDownload PDF (481K) -

JOURNAL FREE ACCESSThe present authors have observed fly larvae discharged from a patient's urethra, who was 26 year old male living at Kumihama-cho, northern Kyoto Prefecture. Of eight larvae in total, three larvae (about 2mm. long) were discharged on August 22nd, two larvae (3.4-4.8mm. long) on 25th, and three larvae (about 10mm. long) on 27th, 1961. Two larvae of the second discharge were estimated as third instar, and were identified as either Sarcophaga septentrionalis or Sarcophaga similis. The infection route was presumable that first instar larvae deposited around dirty penis of the patient invaded through the external urethral orifice into the urethra where they grew up, then they came out three times in the course of their development.View full abstractDownload PDF (507K) -

JOURNAL FREE ACCESSAs a part of the studies on filariasis by members of the Department of Parasitology, the Instute for Infectious Diseases, the University of Tokyo, mosquito surveys were made at the endemic areas of bancroftian filariasis in southern Amami Island during the period of June to October, 1961. A total of 18 species of mosquitoes listed in table 1 were collected from this area. The female mosquitoes collected either by sucking tubes in houses or by light traps were dissected. The positive rates for filarial larvae (all stages included) were 6.4% or 68/1, 059 in Culex pipiens, 0.13% or 1/800 in Culex tritaeniorhynchus and 0.50% or 2/392 in Anopheles hyrcanus and all the other species dissected were negative. The infective stage larvae were recovered from 16 Culex pipiens but not from other species. The infection rates of mosquitoes were much higher in those collected from houses of microfillarial carriers than those in random collections. The densities of mosquitoes and their rates by species were found to differ greatly by the areas surveyed. As the rule, the rates of Culex pipiens among the total collections were higher in urban areas than in the rural villages surrounded by rice fields. As the means of estimating the densities of mosquito breedings in residencial zones, the index was calculated at each community by dividing the number of breeding places of each species by the number of houses, or by dividing the number of positive houses by the total number of houses surveyed.View full abstractDownload PDF (989K) -

JOURNAL FREE ACCESSTo investigate the usefullness of the carbon-dioxide for collecting mosquitoes in field, the mosquito bet nets in which dry-ice was placed were set in the suburbs of Tokyo in summer season of 1961. In one case, up to 5000 female mosquitoes, consisting mainly of Culex tritaeniorhynchus and partly of C. pipiens and Anopheles spp., were collected in a net. Much more mosquitoes were collected by the dry ice trap than by the animal trap using chicken or goat, or by light trap. Dry ice trap adopted in the present study was proved to be highly effective result for collecting the mosquitoes. Diurnal change of prevalence of mosquitoes was also studied using the dry ice trap. The invading number of mosquitoes, both C. tritaeniorhynchus and C. pipiens, appeared to become the peak from 7 : 00 to 8 : 00p.m., and the invasion lasted till 4 : 00 or 5 : 00a.m. in the next morning.View full abstractDownload PDF (545K) -

JOURNAL FREE ACCESSDuring a period from April 1959 to March 1960, a seasonal survey of the occurrence of mosquito larvae were conducted in a residential area in Kawasaki City. In total, 7, 617 mosquitoes belonging to seven species, i.e., Culex pipiens, Aedes albopictus, Ae. vexans, C. tritaeniorhynchus, Anopheles hyrcanus sinensis, C. vorax and C. bitaeniorhynchus, were collected. The most dominant species was C. pipiens, which occupied 94.5% of whole collection. Main breeding sites of C. pipiens were : digged ditches, concrete ditches, night-soil tanks diluted with water and surface waters. As the drainage from dwelling houses pours into the irrigation trenches, C. pipiens larvae were often found even in paddy fields and ponds. Ae. albopictus was found abundantly in grooves of grave stone. The first generation larvae of C. pipiens were found in April, in sheltered places as night soil tank and grassy digged ditch. The peak of the abundance was observed during June-July, but they were recognized until December.View full abstractDownload PDF (591K) -

JOURNAL FREE ACCESSField surveys of the injuries due to the cockroaches and ecological statues of them were conducted in the urban area in Kawasaki City, during a period from February 1960 to March 1961. By means of the interview to the inhabitants, it became clear that the cockroaches were established in 98.3% of the surveyed houses, and 76.6% of the inhabitants are suffering from them. An attempt to obtain a correlation existing between the population density of cockroaches and the environmental facters did not yield any promising result. By trap collecting method, three species; Blattella germanica, Periplaneta japonica and P. fuliginosa were collected. B. germanica prevails in restaurant, cabaret and office room, whereas P. japonica and P. fuliginosa were found predominantly in concrete apartment houses and common wooden houses. B. germanica was caught by traps throughout the year. Even in winter, they showed activity in the surroundings of gas ranges and radiators, but were most abundant during the period from July to September. P. japonica and P. fuliginosa were never trapped in an early season from February to March, but were abundant during warmer season from May to August.View full abstractDownload PDF (624K) -

JOURNAL FREE ACCESSThe development and loss of resistance of houseflies to diazinon in Japan was first reported in 1961 by the present author. Further experiments using a number of housefly strains were carried out in the laboratory. The results may be summarized as follows : 1) When topically tested the Hokota population showed a great increase in (LD)_<50>. It raised, after 6 generations, from 0.5836 microgram per a female fly up to 2.5098 microgram, but further pressure gave only a negligible increase even after 15 generations. 2) At the 10th generation of continuous selection the Hamajuku flies showed a (LD)_<50> level of 1.9146 microgram, but further selection gave only slight increase until the F_<15>. 3) A rather diazinon-susceptible strain from Sodegaura was selected. It induced in the second generation a great increase to a plateau of 10 times of that of the normal Takatsuki strain. 4) In the case of Dejima population, a selection for 10 generations did not increase its level by much more than 5 times. 5) In the case of Hikone population, the pressure did not induce any further increase even after 8 generations, but between the F_<10> and F_<15> the resistance was raised sharply to reach a plateau of 55 times the normal. 6) When kept without selection the Hokota and Ibaraki strains which have about 20 times of the resistance as high as the normal lose their resistance gradually reaching the level about 12 times the normal after 20 generations. These results suggest that resistance to diazinon will not disappear rapidly, as mentioned by Keiding (1959).View full abstractDownload PDF (446K) -

JOURNAL FREE ACCESSIn a contact-test to an insecticide film it was known that the knock down effects widely fluctuate under the presence of minute moisture, besides the fact that the effects of moisture is strongly influenced by the nature of surface to which the insecticide is applied. In order to explain such a phenomenon this investigation was carried out using house-flles. It was experimentally confirmed that, when a volatile insecticide such as DDVP, was applied on a glass plate, the residues evaporates rapidly under the presence of minute moisture. In this case, therefore, the knock down effect rapidly disappears. In a case of an absorptive material such as filter paper, the knock down effect under the presence of minute moisture decidedly increase. A consideration of these facts was given in relation to the behaviour of the residues on the treated materials.View full abstractDownload PDF (407K) -

JOURNAL FREE ACCESSSemi-field and laboratory experiments were conducted to obtain some observations concerning the evaluating methods of house fly population. The number of house flies counted by each evaluating methods such as fly grill, fly paper, fly ribbon and the others was varied by extent of activity of the house flies. The activity, in general, increased at high temperature except at above 30℃. When the number of activated house flies, which recorded in this test, was plotted against the temperature, a straight-line relationship was obtained in 15℃ to 30℃. Old age or starvation has made the flies more active. In a room test, the number of the flies released in the room, vs, the number of the flies which alighted on some surface, did not generally give a straight-line relationship. This was ascertained on the index of the fly grill and fly paper. These results indicated that the counts of house flies obtained from each evaluating methods were influenced by temperature, stage and feeding or starvation of the house flies. It was generally observed in rooms that house flies, which decreased activity in some condition, would choice the resting place on the ceiling or on side of the walls. On the other hand, activated flies have alighted on the floor and concentrated in a center of the room. From this observation, house flies which alighted on the fly grill or on the fly paper placed on the floor, would increase in numbers as temperature increased, and decreased at low temperatures. When various numbers of flies were releaced in a room, the index of the flies of the fly paper was essentially similar to that of the fly grill. The index of the fly grill has more fluctuated than that of the fly paper.View full abstractDownload PDF (1257K) -

JOURNAL FREE ACCESS1) Objective investigation on the density of fly population was very difficult, because the flies showed excellent fecundity and extensive dispersion. The method taken in the present papar was the one for evaluating the effectiveness of insecticides in field and was to compare with the effectivenss of insecticides before and after application. Evaluation of insecticides in field was desirable for simple and stable method to decrease error caused by apparatus and investigators. 2) Up to the present, the effectiveness of insecticides for flies in field was evaluated by fly trap, fly ribbon and fly grill. However, these had merits and dermits. Of couse, the method with combination of several ones was desirable from the point of ideal view. But, the method by fly ribbon and fly grill were concluded to be useful from the point of practical view. 3) In case of extensive appication of insecticides in field, it was better to evaluate with the method avaraging numerical values. When evaluation of the effectiveness was compared with others in limited area, it was better to pick out numerical value that might represent fly population and that should be a value above the average. 4) In the case of a release study of the dispersion of house fly, the number of flies on fly ribbon indicated the proportional relation with the number of emergence.View full abstractDownload PDF (1311K) -
