Aedes albopictus (Skuse) dispersion in Havana City, Cuba, 1995-2018.

Various arboviruses are transmitted to humans by mosquitoes, particularly Aedes aegypti and Aedes albopictus, two invasive and frequently sympatric species. The objective of this study was to evaluate the dispersion and the behavior of Ae. albopictus in relation to houses and its association with other mosquitoes in the province of Havana, Cuba.

Melaleuca quinquenervia (Cav.) S.T. Blake (Myrtales: Myrtaceae): Natural alternative for mosquito control.

Objective: To evaluate an essential oil with larvicide, adulticide and growth inhibitory activity against Aedes aegypti, Aedes albopictus and Culex quinquefasciatus mosquitoes, of medical importance.

Methods: Standardized methodology by WHO was used to determine the levels of susceptibility of mosquito larvae exposed to the essential oil. To evaluate the adulticide activity with the essential oil at different doses, bottles were impregnated according to the methodology CDC.

[Segregation of Aedes aegypti and Culex quinquefasciatus (Diptera: Culicidae) niche under laboratory conditions].

Introduction: Aedes and Culex are two mosquito genuses of epidemiological importance, being Aedes aegypti and Culex quinquefasciatus the predominant ones in urban areas. It is common to find both of them associated in the same breeding sites where they share a lot of things despite the literature.

Objective: To determine if there is inter-specific competence between these two species when they co-exist in a single reservoir under lab conditions.

[Report of habitats used by Aedes aegypti in Havana City, Cuba].

50 habitats used by Aedes aegypti in the urban environment of Havana City were reported. 66% corresponded to artificial deposits, of which 57.5% were classified as unuseful by the population.

[Chemical composition and lethal effect of essential oil from Pimenta racemosa (Myrtales: Myrtaceae) on Blatella germanica (Dictyoptera: Blattellidae)].

Gas chromatography test and Gas chromatography/mass spectrometry test allowed examining the essential oil from Pimenta racemosa leaves (Mill.) J.W.

[Risk factors of pupal infestation with community-based Aedes aegypti in a municipality of Havana City].

The risk factors of pupal infestation with community-based Aedes aegypti were identified in four areas of Playa municipality, located in the urban zone of Havana City The deposits with the highest positivity to the vector were the artificial ones and the low tanks. It was confirmed that 99.03% of the sites visited contained at least one deposit with water, and that 4 areas presented a very similar behaviour in ratio of tanks per site, since in all of them the water was supplied every other day.

[Ecological factors linked to the presence of Aedes aegypti larvae in highly infested areas of Playa, a municipality belonging to Ciudad de La Habana, Cuba].

Objectives: To identify local ecological factors that might have had an impact on the higher infestation rates by the vector mosquito Aedes aegypti seen in four urban health districts of Ciudad de La Habana, Cuba, and to determine the type of containers with the highest number of larvae.

Methods: This is a descriptive study that was carried out in four health areas (Docente, 28 de Enero, 26 de Julio, and 1. degrees de Enero) within Playa, a municipality belonging to Ciudad de La Habana, Cuba.

[Lethal effect of Cuban Myrtaceae on Aedes aegypti (Diptera Cuilicidae)].

The biological activity of the essential foliar oils from 2 Cuban endemic Myrtaceae: Eugenia melanadenia and Psidium rotundatum on A. aegypti larvae was evaluated for the first time at the laboratory level. The probit-log analysis of the results showed the larvicidal effect of both oils with values of CL50 = 0.
