JOURNAL FREE ACCESSThe newly synthesized pyridyl ether compound 4-phenoxyphenyl (RS)-2-(2-pyridyloxy) propyl ether (S-31183), which acts as a juvenile hormone, was evaluated for larvicidal potency against mosquitoes. The residual activity of three formulations, solubilized emulsifiable concentrate (SEC), wettable powder (WP) and granule (G), were compared under laboratory and field conditions. In the laboratory experiment, the granular formulation was most effective against the larvae of Culex pipiens pallens, Aedes aegypti and Anopheles stephensi. Under field conditions also, the granular formulation was more effective both against C. pipiens pallens that are susceptible and those resistant to organophosphorus compounds than a WP formulation.View full abstractDownload PDF (585K) -

JOURNAL FREE ACCESSA colony of Anopheles omorii, which is a treehole breeder and is distributed in limited areas in Japan, was newly established in the laboratory. Eggs and larvae were reared in an insectary at 24±1℃ and 60% RH. Pupae and adults were kept in another insectary at 24±1℃ and 70% RH with a day-length of 17 : 7 (L : D). The first and the last 1hr of the daytime were simulated to dawn and dusk controlling with automatic gradual increase and decrease of voltages. Adults were kept in a nylon mesh cage of 30cm cube with a piece of cotton soaked with a 3% sugar solution. They easily mated in this cage. A mouse, restrained in a wire net, was provided once every 1 or 2 weeks for a blood meal. Eggs were deposited on filter papers attached to the inner wall of a plastic cup (6cm height, 9cm diameter) containing deionized water 2cm in depth. When the larvae hatched, shavings of cedar or fir were put into the cup to prepare good conditions for larval development in the same volume as the water in the cup. As food for the larvae, powdered food (liver and vegetables) and dried yeast were supplied once a day. The developmental period from egg to adult emergence was about 17 days under these conditions. Fifteen generations of the mosquito have been successfully maintained after 1 and half years in the laboratory.View full abstractDownload PDF (879K) -

JOURNAL FREE ACCESSThe subfamily Sarcophaginae (Diptera : Sarcophagidae) from Nepal is revised. A new species, Sarcophaga baruai, is described and figured. An identification key to the male fly of the known genera and species is given. The data of seven newly recorded species from Nepal are provided. Four species are newly included into the genus Sarcophaga Meigen s. lat. and a replacement name, Sarcophaga birganjensis n. nom., is proposed for Boettcherisca nepalensis Kano et Sugiyama.View full abstractDownload PDF (683K) -

JOURNAL FREE ACCESSThe oviposition and egg development of wild female Simulium ochraceum were observed under various constant temperature conditions (15,18,21 and 24℃) in the laboratory. Forty-seven (55.3%) out of 85 blood-fed females successfully oviposited in small tubes; a mean of 82.5% of their mature ova were laid. Hatching occurred in 34 (72.3%) of 47 egg batches laid. Ovulation and egg development rates were more depressed at 24℃ than at lower temperatures. The rate of egg development became higher as temperature increased, with the mean time (±SD) required being 9.8±0.65,7.2±0.27,5.6±0.50,and 4.2±0.27 days at 15,18,21 and 24℃, respectively. Infection with Onchocerca volvulus larvae did not affect oviposition and fecundity of the fly. The fecundity correlated with body size (expressed as the cube of wing length) of the female.View full abstractDownload PDF (401K) -

JOURNAL FREE ACCESSSusceptibility levels to eight insecticides (diazinon, fenitrothion, fenthion, isoxathion, phoxim, temefos, permethrin and tetramethrin) in the adults of the predaceous mite Cheyletus malaccensis were examined by the filter paper contact method. The mite was not susceptible to all the insecticides tested. There was no dose-mortality relation in every insecticide and the mortality was below 30% even after the contact with the filter paper impregnated with 500mg A. I./m^2 of an insecticide.View full abstractDownload PDF (264K) -

JOURNAL FREE ACCESSAn exceptionally rare case of airway invasion of a wingless female adult aphid is reported. The abdominal cut plane of the aphid was found in a histological slide specimen of left B^6 peribronchial tissue of a patient taken during a transbronchial lung biopsy. The patient was a 69-year-old male who had devoted his retirement time entirely to managing a green vegetable farm. Apparently one of the aphids inhabiting on a vegetable had accidentally invaded the patient's respiratory system during his normal breathing as he worked among the vegetables. Whether or not there is actual damage to the peribronchial tissue caused by airway invasion of an aphid is not yet clearly known.View full abstractDownload PDF (650K) -

JOURNAL FREE ACCESSThe fauna and distribution of blackflies in Osaka Prefecture were investigated from various streams by sampling immatures at 24 sites in March 1987. A total of 835 larvae and 105 pupae belonging to 2 genera and 18 species were collected at 16 sites. Seven species, Simulium (Eusimulium) aureum, S. (E.) konoi, S. (E.) mie, S. (E.) subcostatum, S. (Simulium) kawamurae, S. (S.) quinquestriatum and S. (S.) rufibasis, were newly recorded from Osaka Prefecture, of which S. (E.) aureum was the new record from Japan. The predominant species was S. (E.) uchidai (29.9%), followed by S. (E.) subcostatum (16.2%) and S. (E.) mie (13.2%). The most widely distributed species was S. (E.) uchidai, followed by S. (E.) subcostatum and S. (S.) japonicum.View full abstractDownload PDF (407K) -
