RESUMEN El objetivo principal de este artículo es analizar los patrones de migración interna para identificar sus efectos a nivel de División Administrativas Mayores (DAM) de Cuba para los años 2002 y 2012, utilizando las matrices de la Base de Datos Migración Interna en América Latina y el Caribe (MIALC) años 2002 y 2012. Destaca que la población migrante entre las DAM disminuyó en el 2012 al pasar del 2,19% de la población al 1,89%; se mantiene la persistencia de atracción de la capital, que presenta la más alta tasa de inmigración en ambos períodos. Además, en el perfil de los inmigrantes por sexo en 2012 aumentó el predominio de las mujeres, que ya era dominante en el 2002, conservando los rangos de edad, pero con cambios en el perfil educativo que tienden a ser similares entre ambos sexos en el 2012, mientras que en 2002 tenían más diferencias.

ABSTRACT The main objective of this article is to analyze the patterns of internal migration to identify its effects at the DAM level of Cuba for the years 2002 and 2012, using the matrices of the Internal Migration Database in Latin America and the Caribbean (MIALC) years. 2002 and 2012. It is noteworthy that the migrant population among the DAM decreased in 2012, going from 2,19% of the population to 1,89%; The persistence of attraction of the capital, which presents the highest rate of immigration in both periods, is maintained. In addition, in the profile of immigrants by sex in 2012 the predominance of women increased, which was already dominant in 2002, preserving the age ranges, but with changes in the educational profile that tend to be similar between both sexes in the 2012, while in 2002 they had more differences.

The composition and seasonal occurrence of sandflies were investigated in coffee agroecosystems in the Soconusco region of Chiapas, Mexico. Insect sampling was performed on three plantations located at different altitudes: Finca Guadalupe Zajú [1,000 m above sea level (a.s.l.)], Finca Argovia (613 m a.s.l.) and Teotihuacán del Valle (429 m a.s.l.). Sandflies were sampled monthly from August 2007-July 2008 using three sampling methods: Shannon traps, CDC miniature light traps and Disney traps. Sampling was conducted for 3 h during three consecutive nights, beginning at sunset. A total of 4,387 sandflies were collected during the course of the study: 2,718 individuals in Finca Guadalupe Zajú, 605 in Finca Argovia and 1,064 in Teotihuacán del Valle. The Shannon traps captured 94.3% of the total sandflies, while the CDC light traps and Disney traps captured 4.9% and 0.8%, respectively. More females than males were collected at all sites. While the number of sandflies captured was positively correlated with temperature and relative humidity, a negative correlation was observed between sandfly numbers and rainfall. Five species of sandflies were captured: Lutzomyia cruciata , Lutzomyia texana , Lutzomyia ovallesi , Lutzomyia cratifer / undulata and Brumptomyia sp. Lu. cruciata , constituting 98.8% of the total, was the most abundant species. None of the captured sandflies was infected with Leishmaniaspp.
