JOURNAL FREE ACCESSIn order to investigate an effective control method of blackfly larvae in an onchocerciasis endemic area of Guatemala, large scale stream tests were done in the rainy season using various formulations of temephos. The concentration of temephos had no relationship with its carry within a range of 0.2-2.0ppm/10min. There existed a clear tendency in that the larger the water discharge, the longer was the carry of the insecticide. No distinct difference was observed in efficacy among the four formulations, i.e. solid, water dispersible powders (wdp), emulsifiable concentrates (EC) and oil solution, as also between the two application methods, instantaneous pouring and pouring during a 10min period. It is recommended that in future vector control operations of Guatemalan onchocerciasis temephos wdp packed in a bag containing 1.0-1.5g of the active ingredient should be poured into a stream immediately after mixing it with stream water, regardless of the water discharge of stream. With this mode of application, 50-100m carry would be expected in streams infested with Simulium ochraceum, the principal vector of onchocerciasis.View full abstractDownload PDF (598K) -

JOURNAL FREE ACCESSSound trapping of male mosquitoes in the field was improved with the introduction of an artificial swarm marker. A 1×2.5m black cloth was wrapped around the base of a 0.7-m high tripod, and two or four sound traps were hung above the cloth at 0.7 and 1.5m. During dusk, 370Hz sound at 100dB was emitted for 5-sec duration and at 15-sec intervals by each speaker to trap Culex tarsalis and Culex tritaeniorhynchus. The sound-trapped mosquitoes were mostly 3- and 4-day-old males. The standard deviation of their age was much smaller than that of the resting males. Two weeks of removal sampling of Cx. tarsalis males by 3 or 6 sets of 12 sound traps from a stand of marsh fleabane in California may have reduced the insemination rate of the unfed resting female population from 22% to zero, while the insemination rate remained unchanged at 55% in a comparison area. The removal of sound-sensitive males by this technique may prove more efficient for mosquito control than other male manipulation techniques.View full abstractDownload PDF (580K) -

JOURNAL FREE ACCESSFauna and seasonal fluctuation of flies were surveyed in 4 points of swine houses of Takikawa Animal Husbandry Experiment Station, Takikawa, Hokkaido from April to December in 1977 and 1978. Total flies collected by fly-paper strips were 32,506,belonging to 8 families, 13 genera and 20 species, of which Musca domestica constitutes 86.7%, 7.4% in Fannia canicularis, 5.3% in Tephrochlamys japonica, 0.3% in Muscina stabulans and the rest of 16 species constitutes less than 0.1%. Emergence of M. domestica was observed from the end of April to the end of November, F. canicularis from the middle of April to the middle of November, and M. stabulans from the beginning of June to the middle of October. The large populations of those species were seen in July and August. While, the emergence of T. japonica was observed from the early part of April to the end of November, and the first and the second large populations were seen in May and October, respectively.View full abstractDownload PDF (499K) -

JOURNAL FREE ACCESSThe mating, blood feeding and oviposition of Simulium takahasii (Rubtsov), an anautogenous, multivoltine Japanese blackfly, were observed in the laboratory. The results showed that this species readily mates in captivity, and when a male and a female were put together in a small polystyrene tube, the insemination rate was 100% (of 43 pairs examined). In addition, blood feeding was successfully induced on a man's hand and a rabbit's ear on the day of emergence. Fifteen (14.7%) of 102 females fed on a hand, while 6 (37.5%) of 16 females fed on a rabbit. Three or 4 days after the blood feeding, oviposition was observed with 11 inseminated females. However, 2 females which had not been inseminated failed to oviposit. A mean of 158 eggs was laid by a female which had fed on a man, whereas 195 eggs were deposited by a female which had fed on a rabbit. Five to 12 days after oviposition, 80.9-97.9% of eggs laid by 7 females hatched, although the rate was only 38.3% with an egg batch laid by 1 female. Thus, it was found that S. takahasii is a candidate species suitable for laboratory colonization.View full abstractDownload PDF (570K) -

JOURNAL FREE ACCESSAn ecological study of Leptoconops nipponensis oshimaensis (Takaoka and Hayashi, 1977) was carried out at Katoku, Amami-oshima Island. The survey of the seasonal prevalence of adult midges was made during the period from February 1980 to July 1981. The adults were captured by light-traps from late March to late August, and a peak was observed between mid April and mid May. An hourly biting catch was carried out in April 1980,and two peaks of biting activity were observed, in early morning and late afternoon. The survey on the larval habitat was carried out in April 1981. The majority of larvae and pupae were found in the sandy zone with Imperata cylindrica var. major along the beach and the windbreak forest zone (Casuarina equisetifolia, etc.). No larvae nor pupae were found in clay, sandy beach, sandy river side, lawn and sandy grassy zone with Carex breviculmis var. fibrillosa in the windbreak forest.View full abstractDownload PDF (564K) -

JOURNAL FREE ACCESSIn a quadrat sampling made in a 2.4-m stretch. Simulium ochraceum larvae were recovered only from shallow rapids. Lead plates were designed for collecting larvae attached on them. The highest larval density was recorded from the lowest depth (0.2-2.0cm) and the highest velocity (41-66cm/sec). The density increased with velocity increment, but decreased with depth increment. No larva was recorded in the stream of the current velocity less than 10cm/sec. Comparing among the five sampling stretches of 20m each, the increase in discharge was associated with increase both in depth and current velocity, but decrease in larval density, while increase in slope was associated with decrease in depth but increase in both current velocity and mean larval density.View full abstractDownload PDF (459K) -

JOURNAL FREE ACCESSNine species in 3 families of Diptera were determined as the prey of the common yellow dung-fly Scathophaga stercoraria. Eight of these species were recorded as the prey for the first time. Preys for three species of yellow dung-flies, S. scybalaria, S. stercoraria and S. suilla, were serologically determined by the use of micro-Ouchterlony method. Positive reactions were observed against Musca domestica, M. bezzii, M. hervei and Morellia saishuensis in both male and female S. scybalaria and female S. stercoraria, and against M. domestica and M. hervei in male S. stercoraria. No positive reactions were found against these muscid flies in S. suilla. No distinct seasonal changes in the blood source were found in any species of dung-flies examined.View full abstractDownload PDF (571K) -

JOURNAL FREE ACCESSThe tabanid fauna of Okushiri Island, Hokkaido, Japan, was surveyed by collecting female adults with a mosquito-net trap baited with dry ice and by digging larvae and pupae with hand shovels, on August 6 and 7,1983. A total of 544 female adults of 9 species belonging to 3 genera and 39 immatures of 3 species of Tabanus were collected. Tabanus nipponicus, T. chrysurus and T. trigeminus were ubiquitous and predominant. The faunal make-up of this island with a considerable abundance of anautogenous tabanid population markedly differs from that of Rishiri and Rebun Islands. The influence of the livestock farming for the establishment of the tabanid fauna of this island was discussed.View full abstractDownload PDF (381K) -

JOURNAL FREE ACCESSThe egg-batches of Tabanus chrysurinus (Enderlein, 1925) were collected from more or less shaded swamps in or at the margin of forest. The eggs were laid on the underside of leaves of 6 kinds of plants, mainly Phragmites communis Trinius, at the average height of 84.5cm above the ground. The egg-batches were light yellow, and nearly conical in shape with 3 to 4 layers of eggs. Average number of eggs per batch was 525. Seven batches out of nine unhatched ones were parasitized by wasps (Telenomus angustatus). Morphological differences of the egg-batches among closely related 3 species, T. katoi, T. sapporoenus and T. chrysurinus, were interpreted.View full abstractDownload PDF (433K) -

JOURNAL FREE ACCESSMore than 500 patients of tsutsugamushi disease have been reported in Kagoshima Prefecture since 1955. We have, therefore, made a series of investigations in an attempt to determine the vector trombiculid species in this prefecture. Trombiculid larvae were collected from wild rodents, from the soil of endemic areas, and from the black bakelite plates set on the ground. Also attempted were the isolation of Rickettsia tsutsugamushi (R. t.) from the collected mites and the detection of anti-R. t. antibodies from the sera of the sentinel mice exposed to trombiculid larvae in the endemic foci. As the results, 351 fed larvae of trombiculid mites consisting of 2 genera and 9 species were collected from the wild rodents, and 544 unfed larvae belonging to 2 genera and 7 species were recovered by the bakelite plate method; Leptotrombidium scutellare and L. pallidum were included in both of these groups of mites collected. However, the isolation of R. t. from the unfed L. scutellare was unsuccessful. Three out of 174 sera of the experimental mice exposed to trombiculid larvae in the endemic foci were positive for R. t. antigens by the indirect immunofluorescence method.View full abstractDownload PDF (452K) -
