JOURNAL FREE ACCESSThe immature stages of six species belonging to the genus Gymnodia R.-D., namely G. ezensis Shinonaga et Kano, G. tohokuensis Shinonaga et Kano, G. humilis (Zetterstedt), G. lasiopa Emden, G. ascendens (Stein), G. nigrogrisea Karl, were described and illustrated. A key to the third instar larvae of the six species was presented. The eggs of ezensis and tohokuensis were the "basic" phaoniine-type and those of ascendens and nigrogrisea were the "modified" phaoniine-type in morphological characters. All the species described in this paper were proven to hatch from eggs in second instar, and third instar larvae were obligately carnivorous. The shape and color of posterior spiracles of third instar larvae were most characteristic and useful features for the identification of Gymnodia-larvae from Japan. The shape and features of puparia and pupal respiratory horns were also characteristic in some species. The taxonomic and biological significance of some morphological features was discussed.View full abstractDownload PDF (843K) -

JOURNAL FREE ACCESSTwenty kinds of 2,2-dimethyl-3-(2,2-dichlorovinyl) cyclopropane-carboxylic acid esters of acyclic alcohols were synthesized, and their insecticidal activities against houseflies were investigated by three bioassay methods; a topical application, a filter paper contact and a volatile effect test method. Among the α-ethynyl alcohol esters, (E)-1-ethynyl-2-methyl-2-pentenyl ester possessed the highest activity by a volatile effect test method. The insecticidal activities of α-cyano alcohol esters were lower than those of corresponding α-ethynyl esters. The insecticidal activities of the other types of esters were low. From these results, α-ethynyl-2-methyl-2-pentenol was selected as an alcoholic moiety, and the insecticidal activities of 4 kinds of esters containing different acidic moieties were investigated. Among these esters, chrysanthemate showed the highest efficacy by the volatile effect test method. This compound was selected as a unique pyrethroid possessing high volatile effect, and is now promised to be developed.View full abstractDownload PDF (403K) -

JOURNAL FREE ACCESSComparative efficacy of seven insecticides against Guatemalan blackfly larvae was assessed by semi-field trough tests. Chlorphoxim, permethrin and chlorpyrifos-methyl consisted of the most effective group, followed by the second group, temephos. The third group, diazinon, phenothrin and fenitrothion, was inferior to the above two groups. Unlike most organophosphorus insecticides, pyrethroids have a tendency of sharp mortality dropping in relation to the concentration decrease. Blackfly larvae paralyzed by phenothrin showed high recovery. No difference in susceptibility was observed, either of four blackfly species, Simulium ochraceum, S. metallicum, S. callidum and S. horacioi, or of small-, medium- and large-sized larvae of these species. With the same total amount of temephos application, no great difference was observed in mortality, as far as exposure time was in the range of 10 to 120min; but higher mortality was observed with 300min exposure. All available data of temephos by trough and stream tests were reviewed on the basis of concentration per 1min water discharge (ppm-min). Minimum value for the 95% lethal concentration in trough tests was estimated to be 3ppm-min. Most stream tests under review were found effective only when more than 3ppm-min was applied. Exceptions for the above were considered as due either to special particulate formulation or to adsorption of temephos onto particulates suspended in stream water.View full abstractDownload PDF (818K) -

JOURNAL FREE ACCESSAtylotus takaraensis n. sp. is described based on the male and female materials from Tokara Islands, Japan. This species is closely related to Atylotus kakeromaensis Hayakawa, Takahasi and Suzuki, 1982,but can be easily distinguished from it by the much shorter or lacking appendix on vein R_4 of wings in addition to the absence of any markings on abdomen. Key to the 11 Japanese species belonging to the genus Atylotus is presented.View full abstractDownload PDF (548K) -

JOURNAL FREE ACCESSA new species, Myospila japonica, is described and illustrated. This species is closely related to M. laevis (Stein), but differs from it in having 1 or 2 small hairs around notopleural bristle and an incision on apical part of male cerci, and no lateral bristles on scutellum of female. A revised key to the Japanese species of Myospila is presented.View full abstractDownload PDF (369K) -

JOURNAL FREE ACCESSDespite the reports that northern part of Taiwan is the known northernmost limit of distribution range of Culex vishnui, it was more abundant than Cx. tritaeniorhynchus in northern Taiwan. Furthermore, the average temperature in every month of the year in Taipei, Taiwan is nearly equal with that in Naha, Okinawa island. Taiwan strain of Cx. vishnui and Taiwan and Okinawa strains of Cx. tritaeniorhynchus were compared as to some ecological characters under the laboratory conditions. In oviposition preference no clear discrimination was made by Cx. vishnui between tap water and artificial food suspension. The gravid females of Cx. tritaeniorhynchus were reluctant to choose the food suspension when the amount of food in 200ml tap water was over 0.01g in Taiwan strain and 0.1g in Okinawa strain. This difference in oviposition preference may be in some way related to the difference in population level between both species. Duration of larval growth was longer in Cx. vishnui than in Cx. tritaeniorhynchus at temperatures between 20 and 33℃. At 20℃ pupation rate tended to be lower in Cx. vishnui than in Cx. tritaeniorhynchus. It seemed that Cx. vishnui is less adaptable to low temperatures than Cx. tritaeniorhynchus.View full abstractDownload PDF (563K) -

JOURNAL FREE ACCESSSurveys of the chironomid midges breeding in sewage ditches, eutrophicated ponds, and some clean fountains or mountain streams were carried out during the period from December 1981 to February 1982 on the three main islands of the Ryukyu Archipelago, southern Japan, where no information on the freshwater chironomids was available. Adult midges were collected with insect nets on the bank of their breeding places. Bottom sediments containing larval chironomids were collected from the ponds and streams, and the adults were reared in the laboratory. As the result, a total of 26 species belonging to the tribe Chironomini of the subfamily Chironominae were recovered, as in Table 2,among which 17 species were from Okinawa Island, 14 from Ishigaki Island, and 13 from Miyako and Ikema Islands. As for their distribution in relation to the quality of water, 13 species were from eutrophicated ponds such as the eel culture pools and small lakes in urban areas, 9 species were from sewage ditches (5 species were in common to the above two types), 7 species were from clean streams (none of them was in common with the polluted waters), 2 from sedimentation pools containing clean water, and 1 from sea water ditches connected with prawn culture ponds. It was thus observed that their distribution was highly correlated with the degree of pollution with sewage waters, and other chemical or physical environmental conditions. Of 26 species collected and examined, 18 were tentatively identified as species previously described from the neighbouring regions, such as the mainland of Japan, Taiwan, Thailand, Indonesia and Korea, and the scientific names of the rest 8 species were reserved for future studies. It was noteworthy that Chironomus yoshimatsui Martin et Sublette, the species predominantly breeding in all the sewage streams in the mainland of Japan, was not found in our collections from the Ryukyu Islands, and instead, several other chironomid species were breeding in the same types of sewages.View full abstractDownload PDF (5187K) -

JOURNAL FREE ACCESSEgg-batches of Hybomitra tarandina (Linne, 1761) were collected from marshes in Hokkaido in late July and early August in 1981-1982. The collection sites were the same as those for Hy. olsoi egg-batches. The eggs of Hy. tarandina were found on very narrow and mostly erected stems or leaves of 6 kinds of plants, mainly Carex middendorffii Fr. Schmidt and Eriophorum vaginatum L., at the average height of 33.4cm above the ground or water surface. The egg-batches were purplish black in color, and rather elongate-oval in shape with 1 to 3 layers of eggs. Average number of eggs per batch was 399. Thirty-six per cent of egg-batches were destroyed by parasitic wasps.View full abstractDownload PDF (542K) -
