| infective larvae of brugia: escape from mosquitoes into water and subsequent oral infectivity in jirds. | published work showed that third-stage larvae (l-3s) escape into water from dead or dying, brugia pahangi-infected, aedes aegypti. the present study revealed the same escape phenomenon among b. pahangi-infected armigeres subalbatus, anopheles quadrimaculatus, and aedes togoi, and among brugia malayi-infected ae. aegypti and ae. togoi. l-3s maintained in water or in lum's solution for 3 hours retained infectivity when tested in orally or subcutaneously exposed jirds; furthermore, l-3s recovered f ... | 1976 | 8999 |
| development of the timor filaria in aedes togoi: preliminary observations. | developmental stages of the timor filaria recovered from experimentally infected aedes togoi mosquitoes are described. mosquitoes were dissected and examined for larvae beginning 1 1/2 days and continuing daily for 9 days after they had fed on a carrier on the island of flores, indonesia. timor microfilariae develop rapidly to third-stage larvae within the thoracic muscles of a. togoi: the first molt occurs at 3 1/2 days, the second molt as early as 5 1/2 days, and infective forms are found at 6 ... | 1976 | 12255 |
| flight muscle ultrastructure of susceptible and refractory mosquitoes parasitized by larval brugia pahangi. | on parasitization with larval brugia pahangi the infected flight muscle fibres of "resistant" anopheles labranchiae atroparvus undergo the following ultrastructural changes. the fibres become almost totally devoid of glycogen, their sarcoplasmic reticulum becomes elongate and closely associated with muscle fibrils. these fibrils degenerate and vesicles appear both within the degenerate fibril and within elements of the sarcoplasmic reticulum. vesicles accumulate around the worm and degenerate to ... | 1977 | 14324 |
| experimental brugia timori and wuchereria bancrofti infections in certain species of mosquitoes. | laboratory reared aedes aegypti (black eye and jakarta strains), aedes togoi, (taiwan), aedes albopictus, (jakarta), wild caught anopheles barbirostris, (java) and mansonia uniformis, (jakarta) were fed on a carrier with mixed infection of brugia timori and wuchereria bancrofti. b. timori and w. bancrofti were able to develop in a. aegypti (black eye) and a. togoi, with development proceeding more rapidly for of b. timori than w. bancrofti. both species of parasites were readily distinguishable ... | 1977 | 24275 |
| the lethal effects of the cibarial and pharyngeal armatures of mosquitoes on microfilariae. | microfilariae of wuchereria bancrofti and brugia pahangi were killed by the chewing action of the cibarial and pharyngeal armatures and other papillae and spines in the fore-gut of mosquitoes. the proportion of ingested microfilariae that were killed was largely dependent on the presence and shape of the cibarial armature. anopheles farauti no. 1 and anopheles gambiae species a and b have well developed cibarial armatures and killed 36 to 96% of the ingested microfilariae. culex pipiens fatigans ... | 1978 | 30190 |
| incorporation of radioactive precursors into filarial larvae of brugia developing in susceptible and refractory mosquitoes. | the incorporation of tritiated precursors injected into mosquito hosts parasitized by developing filarial larvae of brugia patei has been studied by autoradiography in 2 species of mosquito, aedes togoi in which filarial development was normal and anopheles labranchiae atroparvus in which filarial development was abnormal. in both mosquito hosts there was significant incorporation into 4--5-day-old developing larvae of uridine and amino acids (isoleucine, leucine, valine, arginine, lysine, cysti ... | 1979 | 41893 |
| experimental transmission of wuchereria bancrofti to monkeys. | infective larvae of wuchereria bancrofti from laboratory-raised culex pipiens fatigans and aedes togoi mosquitoes fed on human volunteers in jakarta, indonesia (j strain) and kinmen island, china (k strain) were introduced into taiwan monkeys (macaca cyclopis) by subcutaneous inoculation, by foot puncture, or by permitting infected mosquitoes to feed weekly on the monkeys. some animals were splenectomized and others were treated with varying regimens of immunosuppressants. necropsy was done on m ... | 1979 | 107818 |
| transovarial transmission of japanese encephalitis virus by mosquitoes. | female aedes albopictus and aedes togoi mosquitoes infected with japanese encephalitis virus either by intrathoracic inoculation or by ingestion of a virus-sucrose-erythrocyte mixture transmitted the virus to a small percentage of their f1 progeny. adult f1 female aedes albopictus thus infected transmitted the virus in turn to newly hatched chickens by feeding on them. | 1978 | 203035 |
| disturbed venation, a new sex-linked mutant, in the mosquito aedes togoi. | genetic linkage of a new sex-linked mutant, disturbed venation (dv), in aedes (finlaya) togoi has been studied by utilizing representative markers, s (straw-coloured larva), ru (ruby eye), and y (yellow larva), of the three linkage groups. the dv allele is recessive, disturbs drastically venation of the wing veins, cu1, m1+2, m3+4, r2, r3, and r4+5, and also affects shape of the wings along with loss of many fringe scales. the wings become shortened, especially in females, and somewhat narrowed ... | 1979 | 496477 |
| [the filaria breinlia booliati in the adedes togoi adipose tissue; comparison with the couple dipetalonema dessetae-a. aegypti (author's transl)]. | in the couple filaria-vector breinlia (breinlia) booliati-aedes (finlaya) togoi, the changs observed in the parasited adipose tissue display large similarities with those recently observed in dipetalonemia (molinema) dessetae-aedes (stegomyia) aegypti: same syncitium organisation of parasited adipocytes, and local stimulation of protein synthesis. however, there is an essential difference between the two coules studied: the parasited adipous syncitium is not any more induced by a blood uptake in ... | 2007 | 575875 |
| [experience with the laboratory cultivation of the mosquito, aedes togoi (culicidae)]. | for cultivation of aedes togoi the aquatic infusion of fallen leaves, peat and dry sphagnum (0.15%s) was used and a larval diet (children's haematogen with an addition of polyvitamin "undevit" and glutamic acid) was offered. such cultural medium provides a rapid development of larvae and their survival, high stable weight of pupae, high fecundity and viability of imago. 7 generations were obtained without reducing the quality of culture. | 2007 | 643313 |
| genetics of a new mutant, curved wing, of the mosquito aedes togoi. | a new recessive mutant curved wing (c) in the mosquito aedes (finlaya) togoi (theobald), a vector of various species of filariae in the far east, has been shown to be linked to yellow larva (y), with a recombination value of 13.26 +/- 1.41 to 20.53 +/- 1.41%. these linked alleles are inherited independently of either sex (m), straw-coloured larva (s), ruby eye (ru), or pigmented pupa (p). evidence has now been produced that sex (m)-s, ru-p, and y-c mark the three linkage groups in this species ( ... | 1978 | 666396 |

| the inheritance of a mutant yellow larva in the mosquito aedes togoi. | in the mosquito aedes (finlaya) togoi (theobald), which usually breeds in seawater in tidal pools and is a natural or experimental vector of various species of filariae, the mode of inheritance of a new mutant yellow larva (y) was investigated; the y allele is recessive and inherited independently of sex and its linked alleles, and independently of ruby eye (ru) and pigmented pupae (p), both of which are not sex-linked; therefore y is presumed to be on the third linkage group in this species. th ... | 1977 | 921366 |
| studies on filariasis. iv. the rate of escape of the third-stage larvae of brugia pahangi from the mouthpart of aedes togoi during the blood meal. | the rate of escape of the third-stage larvae of brugia pahangi from aedes togoi which were allowed to probe on a cat and a mouse at time intervals of 5, 10, 20, 30 and 60 seconds was studied. the rate of escape of third-stage larvae at all time intervals was greater during probing on the cat than on the mouse, and was in a logarithmic linear relation to the length of probing time by the mosquito host. the greatest loss (91.35%) of third-stage larvae was in mosquitoes which fed on a cat until ful ... | 1975 | 1127218 |
| mastomys natalensis as an experimental host for brugia malaye subperiodic. | infective larvae of brugia malayi subperiodic obtained by dissection of infected aedes togoi were injected subcutaneously into the scrotal region of mastomys natalensis. from altogether 58 infected male m. natalensis 81% showed consistently or intermittently detectable microfilaraemia, whereas in 19% of the animals no microfilaraemia could be detected at any stage. the mean prepatent period was 136 days; the microfilarial density varied from 1 to 535 per 20 c. mm blood. in those animlas with con ... | 1975 | 1221502 |
| factors affecting transmission of wuchereria bancrofti by anopheline mosquitoes. 4. facilitation, limitation, proportionality and their epidemiological significance. | quantitative understanding of the transmission dynamics of lymphatic filarial parasites is essential for the rational planning of control strategies. one of the most important determinants of transmission dynamics is the relationship between parasite yield, the success rate of ingested microfilariae (mf) becoming infective larvae in a mosquito vector, and mf density in the source of the human blood meal. three types of relationship have been recognized in human filaria/mosquito couples--limitati ... | 1992 | 1475823 |
| survival and infectivity of brugia malayi microfilariae after cryopreservation. | methods were studied for the cryopreservation of microfilariae of periodic brugia malayi. rpmi-1640 tissue culture medium containing 6% dimethyl sulfoxide (dmso) and 15% newborn calf serum was used as cryoprotectant. samples were frozen slowly in the vapor phase of liquid nitrogen prior to emersion in liquid nitrogen (-196 degrees c). the freezing rate was -0.5 to -1.0 degrees c per minute, microfilariae remained viable for as long as, 212 and 375 days, survival rates were 94 to 98% and they wer ... | 1991 | 1948273 |
| ivermectin inhibits molting of wuchereria bancrofti third stage larvae in vitro. | the effect of ivermectin or diethylcarbamazine (dec) on wuchereria bancrofti molting from the third to the fourth larval stage (l3 to l4) was evaluated in vitro. l3 larvae were harvested from laboratory-reared aedes togoi 2 wk after feeding upon a microfilaremic human volunteer. the larvae were kept in an artificial medium (franke's ni medium) with 10% human serum under an atmosphere of 5% co2 for 20 days. experimental tubes also contained ivermectin (0.1-1,000 ng/ml) or dec (0.1-10,000 ng/ml). ... | 1991 | 1992087 |
| exposure to mosquitoes, aedes togoi (theo.), induces and augments opioid-mediated analgesia in mice. | mosquitoes and other biting flies are natural aversive stimuli commonly encountered by wild and domestic animals and by humans. we observed that male mice exposed for 30 min to a low density of female mosquitoes (aedes togoi) displayed significant increases in nociceptive responses which were indicative of the induction of analgesia. this analgesia was blocked by the prototypic opiate antagonist naloxone (1.0 mg/kg). exposure to a novel stimulus had no significant effect on nociception, whereas ... | 1990 | 2176291 |
| species variation in mosquito flight-muscle damage resulting from a single filarial infection and its repercussions on a second infection. | serial sections of females of two highly filaria-susceptible mosquitoes, aedes togoi and ae. aegypti, were examined by light microscopy. following a single brugia pahangi infection, the predominant reaction of flight muscles of ae. aegypti was degeneration, whereas that in ae. togoi was nuclear enlargement, a putative repair response. this also holds true following mechanical injury (beckett 1990), suggesting an inherent species difference in flight-muscle response to injury. the filariae of a s ... | 1990 | 2217122 |
| [the characteristics of aedes togoi susceptibility to plasmodium gallinaceum]. | a high level of mutual adaptation has been established between ae. togoi and p. gallinaceum strains. the level of sensitivity of ae. togoi to the above agent is higher than that of ae. aegypti in the proportion of the individuals infected and the number of agents in them. no correlation in the infectivity of the species compared has been observed. | 1990 | 2290395 |
