| search for a sex pheromone in triatoma mazzottii (hemiptera: reduviidae). | hexane extracts of volatile substances from sexually mature male and female triatoma mazzottii usinger, collected with cold glass trap (-10 degrees c) and evaluated in a wind tunnel, demonstrated the absence of a sex pheromone. the females failed to secrete a liquid from the sixth and seventh abdominal sternite. | 1991 | 1875377 |
| sylvatic focus of chagas' disease in oaxaca, mexico. | during three field trips to the community of 'la humedad', municipality of santiago jamiltepec, oaxaca (a state in the southern part of the mexican republic), live specimens of triatoma mazzottii usinger (hemiptera: reduviidae) were found infected with trypanosoma cruzi. the insects were captured in only one of the dwellings inspected in the locality, and in four small caves where bats and other mammals live. these findings suggest the need for further studies on the existence of a sylvatic cycl ... | 1989 | 2513783 |

| life cycle and influence of age and feeding on the first mating of triatoma mazzottii (hemiptera: reduviidae). | a cohort of 100 eggs of triatoma mazzottii usinger was studied to obtain information on its life cycle. egg incubation took 24 days; mean duration of 1st, 2nd, 3rd, 4th, and 5th instar nymphs was 27, 36, 39, 46, and 64 days respectively; mean time from egg to adult was 236 days. the total duration of the nymphal stages was 212 days. the total nymph mortality in cohort was 16.3%, and the embryonic egg mortality was 14.0%. the greater mortality occurred in the 2nd instar. the average number of egg ... | 1993 | 8107581 |
| molecular taxonomic study of chagas disease vectors from the phyllosoma, lecticularia, and rubrofasciata complexes. | the triatiominae (hemiptera: reduviidae) are hematophagous hemipters of importance because they transmit trypanosoma cruzi, the causal agent of chagas disease. the aim of this study was to define the possible relationships between species of the phyllosoma complex (triatoma mazzottii, triatoma pallidipennis, and triatoma longipennis) and species of other complexes present in mexico that have not been previously analyzed (triatoma lecticularia and triatoma rubida). in addition, it was determined ... | 2005 | 16103598 |
| development of triatoma rubida sonoriana, triatoma barberi, and meccus mazzottii (heteroptera, reduviidae) under laboratory conditions. | the objective of this study was to determine some of the most important bionomic parameters related to the capacity of transmission of trypanosoma cruzi and to estimate the potential transmission capacity and role of 3 groups of recent colonized mexican triatoma barberi, t. rubida sonoriana, and meccus (formerly triatoma) mazzottii in the prevalence of chagas disease cases based on the distribution area of each species. among the studied triatominae species, the life cycle was shorter in t. r. s ... | 2005 | 16252523 |
