JOURNAL FREE ACCESSA nuisance chironomid midge, Polypedilum nubifer breeding in eel culture ponds was controlled successfully with temephos but recovered or alternate species appeared within 1 month. Procladius sp. was tolerable to temephos and rather increased following the treatment. The species composition of zooplankton population in the ponds changed. The decrease of crustaceans and predatory rotifers by the insecticide seemed to cause the increase in other rotifers. Phytoplankton did not show a marked change soon after the treatment but increased its standing crop approximately 1 month after. No appreciable change occurred in the water quality by the application of insecticide.View full abstractDownload PDF (563K) -

JOURNAL FREE ACCESSLarval crowding effects and oviposition preference of 7 strains of Culex tritaeniorhynchus from Far East were studied under laboratory condition. The 7 strains may be grouped according to the experiments into 3 types : (1) Strains Tt and O : The pupation rate at low larval density was higher than in OK-7 strain. No clear discrimination was made between tap water and the conditioned water which had contained the 1st-instar larvae for 1hr at 25℃. The gravid females were reluctant to oviposit on artificial food suspension. (2) Strain OK-7 : The pupation rate was lower in one larva per pot than in two or ten larvae per pot. The pupation rate decreased more sharply in overcrowded density. The ovipositing females showed a significant preference to the certain concentration of artificial food suspension. The females were reluctant to choose the conditioned water which had contained the 1st-instar larvae. (3) Strains A, N, Os76 and S : For the range of density favorable for their larval survival, the similar results to those obtained with strains Tt and O were obtained. However, the oviposition preference was intermediate between strains Tt and OK-7. These results indicate that C. tritaeniorhynchus is a variable species in the ecological characters. Discussion was briefly given on the divergence of oviposition preference for larval food among strains from viewpoint of productivity of larval food source in subtropical and temperate zones.View full abstractDownload PDF (815K) -

JOURNAL FREE ACCESSBiological observations were made on Cephalonomia gallicola (Ashmead), a bethylid wasp which is causative of sting dermatitis in houses, under laboratory conditions (70% R. H., 16L 8D at various temperatures) with host insects, mature larvae of Lasioderma sericorne Fabricius, and a discussion was devoted to the potentialities of injurious pest in the wasp. The observations on adult wasps were made at a temperature of 26℃ and the experiments on development were conducted at various temperatures within a range of 15-40℃. The results are summarized as in the following. The pre-oviposition period was 4.9 days in mated female and 25.8 days in unmated females. The ovarian eggs remained immature in teneral females. In the unmated females the number of mature eggs remaind 5-6 in their ovaries during the long preoviposition period. The width of head capsule in adult females decreased with increased number of eggs in the cases in which the number of eggs on a host was more than 5. The females reared with constant supply of fresh hosts had laid 4.4 eggs on a host at intervals of 2.1 days, and survived a long period of 94 days. The wasps reared without host supply did a shorter period of 10-20 days. The females did not lay their eggs at the temperatures below 15℃ and above 40℃. The threshold temperature for development was determined as 15.8℃ in the two sexes, and the total effective temperature for development as 240.4 day-degrees in females and 227.3 day-degrees in males. The above findings appear to make the species suited for the continued existence under some detrimental conditions and for rapid growing of house-haunting populations under some appropriate conditions, showing that the species is of synovigenic type in the regulation of ovulation and egg disposal.View full abstractDownload PDF (662K) -

JOURNAL FREE ACCESSSilvius oshimaensis, a new species, was described based on the materials from Amami-oshima Island, Japan. This species is closely related to S. dorsalis Coquillett in appearance, but can be easily distinguished from it by having the smaller frontal callus which is well separated from eye-margins. Key to Silvius species from Japan was presented.View full abstractDownload PDF (541K) -

JOURNAL FREE ACCESSAllergenicity (antigenicity) of the common domestic cockroaches in Japan, Blattella germanica (Linne), Periplaneta fuliginosa (Serville), and P. americana (Linne), was investigated by skin tests, RAST, and basophil degranulation test with crude antigens extracted from the triturated, whole cockroach bodies with physiological saline. The following results were obtained : 1. Eight out of 9 volunteers who had been working in an entomological laboratory were positive for the cockroach antigens in prick tests. 2. Five of 7 asthmatic outpatients who visited an allergy clinic were positive for the antigens in intradermal tests, and 12 of the other 34 asthmatic patients gave positive results in IgE-RASTs with the antigens. 3. Two out of the 7 positive volunteers in the prick tests were subjected to basophil degranulation tests; one of them showed positive result for the test, but the other was negative. These results confirmed the allergenicity of the common cockroaches against man, but a discrepancy between man's reactivities in the prick- and basophil degranulation tests to the antigen remained to be investigated. Allergenic difference was also suggested between cockroach- and house dust mite antigens.View full abstractDownload PDF (682K) -

JOURNAL FREE ACCESSIt is necessary to establish a standard method in evaluating an immature simuliid density. This paper describes the results of the comparison of various artificial substrates (i. e., bricks, polyvinyl chloride (PVC) sheets, PVC or silicone tubes) with unit time (10min) collection in the fields in Japan and Guatemala. In Tanzawa, Kanagawa Prefecture, Japan, PVC sheets and normal bricks were compared with unit time collection monthly. Mean numbers of immature simuliids captured by bricks, PVC sheets and unit time collection were 3.6,33.8 and 65.8,respectively (Table 1). Thus, bricks were not recommendable as the artificial substrate. The seasonal occurrence was observed by PVC sheets. Simulium japonicum were dominant (96%) and occurred throughout the year. S. suzuki and S. bidentatum occurred during May to September abundantly, while S. subcostatum January to March. Prosimulium hirtipes group was shown March to April (Table 2). In Mt. Tsukuba, Ibaraki Prefecture, Japan, PVC sheets and tubes were compared with unit time collection monthly. Total number of S. japonicum, dominant species (69%) in the tributary No. 8 of the Yamaguchi River, captured by PVC tubes, sheets and unit time collection were 1,507,875 and 669,respectively (Table 4). In 4 stations from the headwaters to the main stream, the species composition and its seasonal change were observed. S. subcostatum was abundant from the head to the middle reaches; S. japonicum was so at the middle courses where the water runs rapidly; and S. aokii was found in the lower courses of the tributary and the main stream also (Table 3). Each species showed a specific occurrence pattern (Figs. 4-7). In the River Los Lavaderos and the River Guachipilin in the pilot area for research and control project of onchocerciasis, Municipality of San Vicente Pacaya, Department of Escuintla, Guatemala, the silicone tubes were compared with unit time collection fortnightly. In the River Los Lavaderos, the number of larvae and that of species were not different widely between both methods (Table 5), while in the River Guachipilin, unit time collection varied widely according to the skill of collectors (Table 6,Fig. 8). As a conclusion, the author recommends that the use of unit time collection together with the artificial substrates (PVC sheets and/or silicone tubes according to the condition of the stream) is preferable for the evaluation of the immature simuliid density.View full abstractDownload PDF (676K) -

JOURNAL FREE ACCESSLethal and knockdown effects of several insecticides to the drugstore beetle, Stegobium paniceum which is one of Cephalonomia gallicola's hosts, were examined in the laboratory. Fenitrothion showed the most effectiveness among the five tested insecticides by the topical application method. On the contrary, dichlorvos was less effective to the others. In the film contact test, dichlorvos showed very quick knockdown effect in comparison with the other insecticides. Permethrin, propoxur and MTMC showed the remarkable effects in comparison with the organophosphorus insecticides except dichlorvos.View full abstractDownload PDF (259K) -
