Abstract: thermal requirements of aedes (stegomyia) albopictus skuse, 1894 (diptera, culicidae) under laboratory conditions. allochtonous species of ae. albopictus in the american continent can be found in fourteen brazilian states - about fifteen years had been elapsed since the first report of the presence of this species in brazilian territory. considering its potential epidemiological importance and its adaptation to several habitats, it was determined, for this species, the threshold temperature and the thermal constant for egg, larval and pupal stages under laboratory conditions under four constant temperatures and 12:12 hours light-dark photoperiod. the threshold temperature for the egg phase and for the first instar were quite similar: 9.07 oc (k=214.46 degree days) and 9.23 oc (k= 36.64 degree days), respectively. for 2nd, 3rd and 4th instar, the basal-temperature was higher, oscilating between 12.26 oc and 13.95 oc. the threshold temperature for the complete larval stage and for the pupal stage were 12.03 oc (k= 99.48 degree days) and 11.87 oc (k=32.40 degree days) for males and 11.95 oc (k=110.11 degree days) and 11.60 oc (k=35.30 degree days) for females, respectively.

The occurrence of Aedes (Stegomyia) aegypti (Linnaeus) and Aedes (Stegomyia) albopictus (Skuse) in a rural area in Northern Paraná, Brazil and the associated Culicidae fauna
Lopes, José;
Revista Brasileira de Zoologia , 2002, DOI: 10.1590/S0101-81752002000400012
Abstract: to verify the possible occurrence of aedes aegypti (linnaeus, 1761) and aedes albopictus (skuse, 1894) in a rural area in northern paraná, brazil, a water tank was installedon a farm, to work as an artificial breeding site. collections were carried out every 15 days, during a period of 2 years. 12,876 culicidae larvae, belonging to 10 different species, including aedes aegypti and aedes albopictus, were collected, indicating their occurrence.

Boletín de Malariología y Salud Ambiental , 2010,
Abstract: since the first detection of aedes albopictus (skuse, 1894) in spain in 2004 the expansion of this invasive mosquito (diptera, culicidae) has been constant through the east of the iberian peninsula. all the geo-referenced species records are provided together for the first time in this work. the potential negative implications for the public health as well as the spanish and european management against the species are also briefly discussed.

Abstract: Introducción. Dada la importancia de Aedes albopictus en la salud pública, es necesario caracterizar los criaderos para establecer medidas de control. Objetivo. Caracterizar en función de los parámetros físico-químicos y grupos de organismos presentes, los criaderos de los estadios inmaduros de Ae. albopictus en Leticia, Amazonas. Materiales y métodos. Se inspeccionaron 154 viviendas en el área urbana en diciembre 2002 y enero 2003, para buscar criaderos de Ae. albopictus y otros dípteros con estadios acuáticos inmaduros. En los criaderos con resultados positivos se tomaron datos físico-químicos cualitativos y cuantitativos: exposición al sol, ubicación, tama o, material, conductividad, turbidez, oxígeno disuelto, temperatura y presencia de macroinvertebrados y plancton. Los resultados se compararon mediante análisis descriptivos, análisis de componentes principales, dendrogramas de clasificación e índices de diversidad. Resultados. Se encontraron 21 criaderos con larvas de dípteros, 13 con Ae. albopictus; 92% de ellos estaban ubicados en el peridomicilio, en recipientes peque os o medianos, dispuestos en la sombra, con baja turbidez y conductividad, bajos índices de diversidad para macroinvertebrados y altos para organismos productores de plancton. En el análisis de componentes principales, se encontró correlación significativa con ácaros, oligoquetos y hemípteros (macroinvertebrados), y con bacilarofíceas, clorofíceas y cianofíceas (plancton). En presencia de otros culícidos, las larvas de Ae. albopictus fueron escasas. Conclusión. En este estudio se encontró que las hembras de Ae. albopictus depositan sus huevos en depósitos de agua recién establecidos con disponibilidad suficiente de recurso, baja conductividad y turbidez, y menor competencia intraespecífica e interespecífica. Introduction. Because the role of Aedes albopictus as an incriminated vector of several viral pathogens, its control is important to human health. To establish appropriate control methods, characterization of the larval habitats is a necessary first step. Objective. Habitats of the immature stages of Ae. albopictus were characterized with respect to physical-chemical parameters and by floral and faunal arrays present. Materials and methods. Leticia is located at the southernmost tip of Colombia on the banks of the Amazon River. In the urban area, 154 houses were inspected in December 2002 and January 2003. Physical-chemical data were collected, including exposure to sunlight, location, container size and material, water conductivity, and dissolved oxygen. Macroinvertebrates and

Abstract: Considerando a importancia dos percevejos predadores como agentes de controle biológico e a necessidade de se otimizar sua produ o massal, realizou-se o presente trabalho para avaliar a influência do peso corporal sobre a sobrevivência e a reprodu o de fêmeas de Podisus rostralis (St l) (Hemiptera: Pentatomidae). Os tratamentos foram constituídos por fêmeas desse predador com peso médio de: 39,5 mg, 45,5 mg, 51,5 mg, 57,5 mg e 63,5 mg. O período de preoviposi o foi menor nas fêmeas mais pesadas, enquanto o número de ovos e de ninfas por dia apresentou rela o linear positiva com o peso das fêmeas de P. rostralis. A longevidade das fêmeas desse predador foi semelhante entre tratamentos, porém n o apresentou tendência de varia o em raz o do seu peso corporal. Como o objetivo de uma cria o massal é produzir o maior número possível de ninfas por dia, recomenda-se o uso de fêmeas de P. rostralis com peso acima de 60,0 mg.
