The aim of this study was to determine the population dynamics of D. citri and its relation with the abundance of vegetative shoots, temperature and precipitation in Huimanguillo, Tabasco. The work was done by sampling fortnightly from September 2010 to August 2011 in a plantation of Persian lime (Citrus latifolia Tanaka) of 1 ha. Population dynamics of eggs and nymphs was determined by collecting vegetative shoots, and adult dynamics by capturing them in yellow sticky traps. The highest incidence of D. citri was between March and June, coinciding with the abundance of vegetative shoots and high temperature. The abundance of eggs and nymphs showed high correlation with that of vegetative shoots, moderate correlation with temperature, and negative correlation with rainfall. The incidence of adults exhib...

Surveys of 54 mosquito breeding sites over a period of 24 months yielded 150 sample collections with a total of 194 Anopheles cadavers infected by the pathogenic fungus Batkoa apiculata (Entomophthorales: Entomophthoraceae). Apart from their basic scientific value, these results also offer some hope about the possibilities to use fungus-based biocontrol against Anopheles species that vector malaria in Brazil.

Por el momento es imposible decir si las colecciones Brasileñas representan un conocido taxón (previamente descrito) o un nuevo miembro aún no descrito de este complejo de especies. Estos nuevos registros del complejo E. grylli expanden el conocimiento sobre Entomophthorales en Brasil y abren oportunidades para posteriores estudios de estos patógenos de saltamontes que causan epizootias naturales y que en muchas ocasiones redujeron significativamente las poblaciones de diversos acrídidos alrededor del mundo.

Los métodos de captura utilizados fueron las trampas dealcohol, trampa de luz y captura directa sobre sus plantas huésped. Se obtuvo como resultado un total de 4 600 especímenes con los tres métodos de colecta, siendo las trampas de alcohol las que registraron el mayor número de organismos con 2 927, seguidos de las trampas de luz con 1 595 y por último sobre sus plantas huésped con 78. La fluctuación de X. volvulus presentó dos picos poblacionales en todas las localidades estudiadas, uno al inicio (enero-abril) y otro hacia el final (septiembre, noviembre y diciembre) del periodo de estudio, coincidiendo en la mayoría de los casos con el periodo de lluvia de la zona.Además se determinó que esta especie se encuentra presente todo el año pero con poblaciones bajas.

The Scolytinae insects are commonly known as bark or ambrosial beetles because of their feeding habits. Among them, some species restrict their reproductive activity to a host plant or a small number of them, whereas others are highly polyphagous. in order to evaluate the population dynamics of Scolytinae species, populations of Xyleborus ferrugineus and X. affinis in ecosystems from Tabasco, Mexico were studied.

The study of diversity associated with conservation sites allows estimating the richness and abundance of species, their population dynamics as well as understanding the population behavior over time. The species richness and abundance of Scolytinae and Platypodinae was studied in the Chontalpa Ecological Reserve (REC) and the José Narciso Rovirosa Botanical Garden (JBU) in Tabasco, Mexico. Insects were captured with ethyl alcohol traps. A total of 7 057 specimens belonging to 46 species and 26 genera were collected and identified; 42 species from 23 genera belong to Scolytinae and four species from three genera to Platypodinae. The species Bothrosternus foveatus (Blackman, 1943); Dendroterus luteolus (Schedl, 1951); Dendrocranulus guatemalensis (Hopkins, 1915); Micracis swainei (Blackman, 1920); Pseudothysanoes tenellus (Wood, 1971) y Ambrosiodmus obliqu...
