JOURNAL FREE ACCESSA series of field investigations was made on the imaginal mosquito populations occurring in a suburban area of Nagoya City, central Japan. 1) During the period from May 1972 to May 1973,an investigation was made on the seasonal fluctuation of the imaginal masquitoes. As a result, most (99.6%) of the adult mosquitoes collected with light traps were Culex pipiens group. 2) Discriminant function was applied to the identification of the two house mosquito biotypes, or autogenous Culex pipiens molestus and anautogenous C. p. pallens. As a result, 66.4% of the males and 75.4% of the females in the collections were regarded as C. p. molestus. 3) A breeding place of C. p. molestus was found to be the final settling tank in sewage treatment plant adjacent to the area. Female mosquitoes reared from larvae and pupae collected at the tank were tested for the presence of autogenecity, and 96% of them proved autogenous.View full abstractDownload PDF (561K) -

JOURNAL FREE ACCESSAn ecological study was made on the overwintering populations of the house mosquito, Culex pipiens pallens, in 6 caves of 3 localities in Aichi Prefecture (Fig. 1), central Japan, during the period from October 1969 to March 1970. Female mosquitoes captured were C. p. pallens (Cpp), C. hayashii, C. orientalis, C. vorax and Anopheles sinensis in order of decreasing numbers (Table 1). Overwintering females of Cpp appeared on the inside walls of the caves in October, became most abundant in January of the following year and decreased toward March. Monthly fluctuation patterns in catch size of the mosquitoes were similar to those obtained separately by counting without removal (Fig. 2). Wing length distribution of the overwintering Cpp females did not show the normal distribution, whereas that of field-collected summer populations proved to be the normal one (Fig. 3). Using probability paper analysis, the overwintering populations were found to be composed of two different groups with regard to wing length; one was a long-winged group which accounted for about 90% of the populations and the other was a short-winged group (Figs. 4,5 and Table 2). Similar phenomenon had been observed in the same localities in the previous year (Makiya et al., 1971). In order to know closely whether autogenous C. p. molestus (Cpm) were intermixed with the overwintering anautogenous Cpp populations, discriminant function derived from 5 characters was applied to differentiate the two biotypes. As a result, most of the ovewintering females were identified as Cpp, but a few individuals (8∿10%) were morphologically regarded as Cpm. The overwintering short-winged group, however, seemed not be Cpm, because wing length of most of the individuals regarded as Cpm fell within the range of the long-winged group (Table 3 and Figs. 4,5).View full abstractDownload PDF (934K) -

JOURNAL FREE ACCESSA laboratory colony of adult mosquitoes, Aedes albopictus (Skuse), was experimentally fed with royal jelly, a glandular secretion of the honey bee Apis mellifera L. Results indicated that mosquitoes, deprived of a blood meal, showed an increased tendency to develop mature ovaries and oviposit viable eggs as a result of feedings of increasing concentrations of royal jelly. This experiment was divided into two stages of observations as outlined below. The initial stage of this experiment was concerned with observations of accelerated follicular development as a result of royal jelly feedings at various concentrations. A total of 720 females and 360 males, which emerged within a 24 hour period, were maintained in equal numbers in 12 separate cages (25×25×25cm). Ten cages of mosquitoes were fed graded concentrations of royal jelly (0.5% to 20.0%). The remaining two cages of mosquitoes each received daily feedings of a 5% sugar solution, however, the mosquitoes in one of these cages were given a blood meal from a mouse on their first day after emergence. On the 8th day after emergence all of the female mosquitoes were dissected and stages of follicular development were recorded based upon the criterion of Christophers (1911). It was found that the percentage of mosquitoes which attained stage V of follicular development increased as a result of feedings of increasing concentrations of royal jelly. The second stage of this experiment was an attempt to determine the viability of mosquito eggs which had been oviposited following royal jelly feeding. A total of 600 female and 600 male mosquitoes were divided equally into 5 separate cages. Mosquitoes in three cages received royal jelly feedings in concentrations of 5,10,and 20% for three days, and the remaining two cages served as controls and received feedings of other diets for three days. After this initial three day period, approximately 40 females from each cage were placed in separate tubes containing water to facilitate oviposition. Royal jelly feeding was maintained for nine more days and on the 9th day the number of oviposited eggs was observed. Also, the degree of follicular development was examined by observing the number of follicles in each stage of develoment. It was found that mosquitoes were able to oviposit viable eggs as a result of royal jelly feeding.View full abstractDownload PDF (483K) -

JOURNAL FREE ACCESSThe bait tablets containing 0.1 or 1% propoxur, carbary, dieldrin, DDT, BHC, lindane, naled, fenthion, malathion, fenitrothion, diazinon, or trichlorfon showed repellency more or less against German cockroaches, when tested with the similar tablets containing no insecticide. Propoxur, naled, and BHC were highly repellent, whereas trichlorfon was little. The consumption of the trichlorfon-bait by an alive cockroach per day was much greater than that of the propoxur-bait on the first day of the experiment, whereas the consumption of the nonpoison bait kept as the control increased later on. Many cockroaches (more than 10%) could survive on the bait containing 0.5% propoxur and 20% boric acid, although the bait containing only the latter would have given the complete mortality. The strong initial repellency of propoxur in the bait would be responsible for the decreased mortality of the cockroaches. The consumption by the living cockroaches of both poison (propoxur and trichlorfon) and nonpoison baits decreased as the tests progressed. The similar trend was observed when we treated the cockroaches with the sublethal doses of the poisons. Satisfaction of their appetite or loss of their appetite by the intoxication, or both are the possible causes for the decreased bait consumption.View full abstractDownload PDF (613K) -

JOURNAL FREE ACCESSA series of surveys have been carried out on the spider fauna of houses in various districts of Nagasaki Prefecture, and on the role played by various spider species as predators of house-infesting insects. In total, 45 species belonging to 37 genera and 22 families were collected, among which 29 species (24 genera and 13 families) were the weavers, and 16 species (13 genera and 9 families) were the hunters. Oecobius annulipes and Theridion tepidariorum were the most common species encounter in the houses surveys, and their seasonal changes in population density and the indoor distribution were investigated in detail. The behavior of the two common wandering spiders in houses, Heteropoda venatoria and Selenops bursarius, was specially investigated. They were found most abundantly in barns, but were also common in living rooms with straw mat floor (tatami), in corridor, in latriums and in kitchins. A variety of insect species were shown to be killed by the spiders; the preys confirmed in the present survey were the members of the orders Collembola, Blattaria, Orthoptera, Isoptera, Lepidoptera, Hymenoptera, Coleoptera and Diptera. The cockroaches (Blattaria) were found to be caught mainly by the wandering spiders, such as H. venatoria, H. focipata and S. bursarius. Mosquitos and chironomids (Diptera) were captured by the wandering spiders such as S. bursarius, Hasarius adansoni and Plexippus paykulli, and trapped by the viscid lines of weavers. Houseflies (Diptera) were observed to be killed by most of the house spider species, especially by the wandering ones. In an observation on the predation of a wandering spider, S. bursarius, a total of 42 winged ants, 22 chironomids, 6 houseflies and 2 cockroaches were found to be sacrificed while the author had watched it for 4.5 hours every night for 11 consecutive days.View full abstractDownload PDF (729K) -

JOURNAL FREE ACCESSIn 1907 Shelford described "Phyllodromia japonica" from "Riou-Kiou, Oshima, Japan." He soon transferred it to the genus Liosilpha, but it had remained neglected until Princis included it in the genus Shelfordina in his Blattariae Catalogus (1969). In 1973 I had an opportunity to examine the type specimens (2 ♀♀) in the Museum National d'Histoire Naturelle, Paris, and found them to be a Symploce species which was the same with "Ischnoptera testacea (Shiraki, 1908)" known from Kyushu, Japan. In the present paper, the synonymies were clarified and a description was given for both the sexes, as the male insect has never been described. I took this opportunity to designate the Lectotype specimen to be one of the females in the Paris Museum, the right side one in Fig. 1. For the Allotype specimen I selected a male individual taken by Mr. S. Tachikawa at Yuwandake, Amami-oshima in the Ryukyus. (Fig. 2) The distributional range of this species hitherto known covers Amami-oshima, Takarajima, Tenagashima and Kyushu (Kumamoto, Unzen, Amakusa, Nagasaki). Specimens from Takarajima have a more rounded supra-anal plate in the male insect (Fig. 14). It is interesting to note that this species is most closely allied to Symploce okinoerabuensis Asahina (1974), a cavernicolous species found from Okinoerabu Island situated to the south of A-mami Island.View full abstractDownload PDF (851K) -

JOURNAL FREE ACCESSBy topical application, we studied diazinon and malathion susceptibility of 30 F_1 subcolony of houseflies, Musca domestica L., which were established from 30 females collected from a farm in Hokota. The LD_<50>'s of diazinon against the most susceptible and resistant subcolonies were 0.095 and 2.6μg per female fly respectively. When malathion applied at the dose of 10μg per female fly, the mortality of subcolony varied from 0 to 100%. We concluded that susceptibility of houseflies to insecticide varied widely even when they were collected from the same breeding habitat.View full abstractDownload PDF (365K) -

JOURNAL FREE ACCESSIn order to clarify the actual situation of insects of medical importance carried into Japan by aircrafts, the survey was conducted by checking the inside of the international aircrafts just after arriving at Tokyo International Airport, during the period from July 1972 to August 1973. Of 42 aircrafts surveyed, 10 species of the pest insects, excluding several unidentified species, were captured in 24 aircrafts. Musca domestica Linne and Culex fatigans Wiedemann were collected most abundantly, 59 and 24,respectively. Of 10 species identified, 5 species were exotic ones and the other 3 were either the exceptional or rare ones around Tokyo. It is worth to note that an engorged female of Aedes aegypti (Linne), an important vector of yellow fever, and Anopheles subpictus Grassi, a malaria vector, were caught. It must be emphasized that important mosquito species were carried mainly by the flights via Bangkok, Hongkong or Manila, whilst the house flies were abundantly carried by Seoul and Khavarovsk lines. In order to know the possible place where the mosquitoes embarked on the aircrafts, a discussion was made considering the actual time schedules of the flights. As for the house flies the levels of the insecticide susceptibility between the captured insects and Japanese colonies were compared.View full abstractDownload PDF (594K) -

JOURNAL FREE ACCESSLethal effects of a juvenile hormone analogue, methoprene (ZR-515[○!R]), and its slow-release formulation A (SR-10[○!R]), were tested on larvae and pupae of Culex pipiens pallens and Culex tritaeniorhynchus at different developmental stages. Methoprene, which contains more than 90% of the active component, was emulsified with 0.03% (w/w) Tween 80 and 5% alcohol solution. Certain amount of the diluted emulsion or slowrelease formulation A, was stirred into glass jars containing 200ml of distilled water and 30 mosquito larvae or pupae at the particular developmental stage. Minute amount of brewered yeast was added as a food. The temperature was maintained at 25℃. The individuals which failed to moult into normal pupae or adults were counted every day until all survived larvae became adults. EC_<50> values of methoprene against Culex pipiens pallens were 0.03ppm at late 3rd instar, 0.02ppm at late 4th instar, 0.0006ppm at pharate pupal stage and 1.0ppm at one-day-old pupae, respectively. The lethal effect of slow-release formulation A to C. pipiens pallens larvae proved to be more potent than methoprene perse, but not to pupae. Almost the same figure was found in the experiments on Culex tritaeniorhynchus. The phenomenon that the susceptibility to the compound increases gradually toward the pupation and decreases drastically after the pupation was in accord with the theory on the secretion and action of juvenile hormone in the physiological and endocrinological studies.View full abstractDownload PDF (498K) -
