two strains of anopheles atroparvus, one resistant and another sceptible to ddt and two of anopheles stephensi, one resistant and one susceptible to ddt were tested for their irritability to ddt. various laboratory investigations of the effects of insecticides on mosquito behavior and their irritability were carried out. in these series of experiments a comparison was made between the results o...

Updated information on the distribution of Anopheles in the Valencian Autonomous Region of Eastern Spain is presented. Larval surveys over a four year period (20052008) detected seven species, all in the subgenus Anopheles, namely Anopheles algeriensis, An. atroparvus, An. claviger, An. maculipennis, An. marteri, An. petragnani and An. plumbeus. Distribution, biology and ecology of each are dis...

In October 2010, one case of autochthonous malaria due to Plasmodium vivax was diagnosed in Spain. The case occurred in Aragon, north-eastern Spain, where the vector Anopheles atroparvus is present. Although the source of infection could not be identified, this event highlights that sporadic autochthonous transmission of vector-borne diseases in continental Europe is possible and calls for enha...

BACKGROUND A field study on diversity and distribution of anophelines currently present in a past endemic malaria area of Spain was carried out in order to identify possible risk areas of local disease transmission. METHODS Multiple larval sites were sampled from June to October of 2011 in the Region of Somontano de Barbastro (Northeastern Spain). The sampling effort was fixed at 10 minutes w...

Background: Malaria is a former endemic problem in the Camargue, South East France, an area from where very few recent data concerning Anopheles are available. A study was undertaken in 2005 to establish potential malaria vector biology and dynamics and evaluate the risk of malaria reemergence. Methods: Mosquitoes were collected in two study areas, from March to October 2005, one week every two...

When exposed to a human host, Anopheles gambiae started probing 4 h post-eclosion, but 95% successfully blood-fed by 16-20 h with maximal blood volumes of 5- 10 microl per female. When fed sugar, the 95% feeding was not observed until 36-40 h post-eclosion; sugar meals appeared to interfere with blood meals. Similarly in An. atroparvus, maximum volumes were 10 microl when starved but only 6 mic...

Acoustic characteristics of three representatives of malaria mosquitoes of Palearctic complex Anopheles maculipennis: An. messeae, An. maculipennis s.s. and An. atroparvus were studied. It was found that the spectra of fundamental frequencies for males of all species is significantly higher than for females. An. atroparvus and An. maculipennis have close acoustic characteristics, which explains...

The flight potential and metabolism of two malaria vectors, Anopheles gambiae s.str. and An. atroparvus, were analyzed on flightmills. The flight distance, the flight time, and individual flight activities of females were recorded during 22 h flight trials. The glycogen and lipid before flight, after flight, and of unflown controls were measured for starved, sugar-, or blood-fed females. Maxima...
