| previtellogenic development and vitellogenin synthesis in the fat body of a mosquito: an ultrastructural and immunocytochemical study. | we describe two phases, previtellogenic and vitellogenic, in the activity of the trophocytes in the fat body of the mosquito aedes aegypti. the previtellogenic phase, leading to trophocyte competence to synthesize vitellogenin (vg), occurred during the first 3 days after eclosion. this phase was characterized by enlargement and activation of the nucleoli, proliferation of ribosomes and rough endoplasmic reticulum (rer), development of golgi complexes, and extensive invaginations of the plasma me ... | 1983 | 6349013 |

| primary lymph node responses to mosquito bites. | post-auricular lymph node responses and changes in fresh weight of thymus and spleen of hamsters and mice at 4 and 8 days after primary exposure of both ears to 20 bites by the mosquito aedes aegypti were studied quantitatively. in both hosts lymph node changes characteristic of the development of cell-mediated immune responses and those which are believed to lead to antibody production occurred, with the emphasis on the latter phenomena. no reactions of thymus and spleen were observed. the resp ... | 1977 | 848080 |
| an autocidal ovitrap for the control and possible eradication of aedes aegypti. | a revolutionary, autocidal ovitrap has been developed as a promising weapon for the control and possible eradication of ae, aegypti, the principal vector of dengue haemorrhagic fever (dhf), in urban high dhf endemic areas. a study carried out with this trap in a highly endemic area for dhf in singapore city, namely the rochor area, has shown this trap to be superior to all other domestic habitats in attractiveness to ovipositing ae. aegypti females. | 1977 | 887996 |
| autogeny in diverse populations of aedes aegypti from east africa. | autogeny in aedes aegypti was found in many diverse populations throughout the range of east africa. degree of autogeny is proposed to be measured either by a relative method using an autogeny index (aix), or by direct count of eggs in dissected ovaries and expressed in percentage. degree of autogeny varied from population to population but it was always higher in the dark feral ae. aegypti formosus than in the domestic ae. aegypti aegypti form. the highest degree of autogeny occurred in the dar ... | 1977 | 871038 |
| fine structure and role in behavior of sensilla on the terminalia of aedes aegypti (l.) (diptera: culicidae). | the terminalia of male and female aedes aegypti (l.) bear numerous hairs of various shapes and lengths, all of which are mechanoreceptors. each hair is innervated by one bipolar neuron which contains ciliary rootlets, two basal bodies, and a region assuming the structure of a non-motile cilium. at the distal tip of the dendrite is a tubular body, a characteristic of cuticular mechanoreceptors. covering the outer dendritic segment is a cuticular sheath which ends proximally in a net-like felt-wor ... | 1977 | 845972 |
| ultrastructural changes in midgut cells of female aedes aegypti l. (insecta, diptera) after starvation or sugar diet. | the ultrastructure of the epithelial cells in the posterior part of the midgut in female aedes aegypti was partly changed after starvation periods of 5 or 8 days. most obvious is a drastic reduction of the amount of rough endoplasmic reticulum (rer), which is responsible for the synthesis of enzymes for blood digestion. a similar influence on rer membranes is to be observed in mosquitoes fed on sucrose solution only, without additional blood meals. | 1977 | 837408 |
| [studies of the time of effectiveness and the characterization of compounds in insecticide tests with aedes aegypti]. | the contact-toxicity of 5 insecticides (2 chlorinated hydrocarbons, 2 organophosphate compounds 1 p-substance) are tested against aedes aegypti l (adults). because of the relationship between dosage (quantity of application) and time of effectiveness of a compound, we are able to design a specific curve of time-efficacy of each insecticide at graded intervals (= increasing dilutions). this curve may be characteristic of different pure compounds--possibly in connection with other features. the ti ... | 1977 | 67813 |

| ultrastructural changes in intersegmental cuticle during rotation of the terminal abdominal segments in a mosquito. | the terminal abdominal segments of male aedes aegypti rotate 180 degrees within 24 hr after adult emergence, rotation occurring in the intersegmental membrane between abdominal segments vii and viii. the ultrastructure of this rotating membrane is compared with non-rotating intersegmental membranes at different developmental stages. the deposition of cuticle in both the rotating and non-rotating intersegments appears ultrastructurally similar, and follows the sequential pattern described for the ... | 1977 | 906015 |
