“…These structures are a continuation of the hypopharynx and the labrum (Forattini 1973) and are involved in the process of blood meal digestion, probably initiating the mechanical breakdown of the cells. It is not known for certain what adaptive advantage would be obtained by a population with ten horizontal teeth over one with eight teeth.…”

ABSTRACT. Polymorphism, inter-population and inter-specific variation in Nyssomyia intermedia (Lutz & Neiva) and Nyssomyia neivai (Pinto) (Diptera, Psychodidae, Phlebotominae). Nyssomyia intermedia (Lutz & Neiva) and Nyssomyia neivai (Pinto) are morphologically very close and both present great variation in some structures. The objective of this study is a description of the variation among the females of these species in populations from the States of Minas Gerais and São Paulo. The morphological structures studied were the number of horizontal teeth in the cibarium and the number of rings and the shape of the terminal knob of the spermathecae. The spermatheca rings are significantly more numerous in N. intermedia than in N. neivai and the simple shape of the terminal knob predominated in both species. Regarding the cibarium, eight to eleven teeth have been found in both species, with up to twelve teeth in the latter. The number of horizontal teeth and the shape of the terminal knob of the spermathecae were variable throughout the populations of both species and all structures were polymorphic in the populations studied.

“…The eggs are deposited in groups under the leaves of aquatic plants, particularly grassy plants 1 , and the larvae attach themselves to the roots and take oxygen directly from the aeriferous parenchyma. These plants have the capacity to increase their biomass rapidly, through sexual or asexual reproduction, thus constituting an excellent substrate for many animals 2 .…”

“…The epidemiological significance of the group comes from the fact that they have been found naturally infected by dangerous arboviruses, such as Oropouche 1,3 In June and April 2010, immature forms were systematically collected along the edges of the breeding sites with the aid of entomological scoops (BioQuip®). The water was poured into polyethylene trays and any larvae and insects that were present were removed with the aid of a thin brush.…”

INTRODUCTION: Findings of immature forms of Coquillettidia venezuelensis in temporary breeding sites, without the presence of aquatic plants or other submerged plant tissue are reported. METHODS: A systematic scooping technique to collect specimens was used at the breeding site. RESULTS: Immature forms of Coquillettidia venezuelensis, Anopheles rangeli, An. evansae and Culex sp. were collected from areas of the hydroelectric power station of São Salvador, State of Goiás. CONCLUSIONS This is a novel finding relating to the bioecology of Cq. venezuelensis, a species of medical interest that has been found naturally infected with arboviruses, including Oropouche and West Nile virus.

“…KEY WORDS: Survival, development time, wing length, food, larval rearing rural species which insistently attacks human and animals (Forattini 1965), and as a consequence of its bites, it can reduce caws milk production in some areas of Argentina (Ludueña Almeida & Gorla 1995). Colonization of this species was not possible yet, and it is an important step for the development of laboratory studies, such as biology (which will provide valuable information for its control), on resistance to insecticides, and on its role in disease transmission.…”

Neotropical Entomology 37(6): 729-732 (2008) Efecto de la Composición de la Dieta sobre el Desarrollo del Mosquito de Inundación Ochlerotatus (Ochletotatus) albifasciatus (Macquart) (Diptera: Culicidae)RESUMEN -Un paso importante para la colonización de Ochlerotatus albifasciatus (Macquart) es conocer las condiciones óptimas para la cría de las larvas, lo cual además posibilita el desarrollo de experimentos en el laboratorio. En este trabajo se estudió el efecto de la dieta sobre el desarrollo de O. albifasciatus. Para ello se criaron cohortes de 20 larvas I utilizando cinco tipos de dietas: una mezcla 1:1 de levadura y TetraMin ® , una mezcla 1:1 de materia orgánica fi na y gruesa, gramíneas cortadas y sumergidas en agua 1h o 24h antes de incorporar las larvas, y una mezcla 1:1:1 de gramíneas cortadas, materia orgánica fi na y materia orgánica gruesa. Para cada cohorte se registró la supervivencia, y para cada individuo, el tiempo de desarrollo desde larva I hasta pupa y la longitud del ala de los adultos. El efecto de la dieta sobre estas características se analizó mediante un ANOVA de una vía. Los resultados mostraron que la dieta afecta la supervivencia y la longitud del ala, obteniéndose los mayores valores de estas variables (79-100 % y ~ 4,46 mm) con las dietas consistentes en materia orgánica o materia orgánica más gramíneas. El tiempo de desarrollo no estuvo afectado por la dieta, aunque el tiempo más corto (8,1-8,3 dias) y la menor variación entre réplicas se registraron al criar las larvas con materia orgánica o materia orgánica más gramíneas. Se concluye que las dietas consistentes en materia orgánica o una mezcla de ésta y gramíneas, son las más efectivas para la cría de O. albifasciatus.PALABRAS CLAVE: Supervivencia, tiempo de desarrollo, longitud del ala, alimento, cría de larvas ABSTRACT -One important step for the colonization of Ochlerotatus albifasciatus (Macquart) is to determine the optimal conditions for larval rearing, which makes possible the development of experiments comprising larval rearing in the laboratory. In this research the effect of diet composition on the development of O. albifasciatus was studied. For this purpose, cohorts of 20 fi rst instars were reared using fi ve diets: 1:1 mix of yeast and TetraMin ® , 1:1 mix of fi ne and coarse organic matter, grass cuts soaked in water for 1h or 24h before larvae incorporation, and 1:1:1 mix of grass cuts, fi ne organic matter and coarse organic matter. Survival was recorded for each cohort, while development time from fi rst instar to pupa, and adult wing length were recorded for each individual. The effects of the diet on the observed traits were analyzed by one way ANOVA. Both survival and wing length were affected by diet, being signifi cantly higher (79-100% and ~ 4.46 mm) on diets consisting of organic matter or organic matter plus grass than on those consisting of yeast plus TetraMin ® or grass. Development time was not affected by the diet, although the shortest time (8.1 to 8.3 days) and lower variation between replicates...
