Three species of Caribbomerus Vitali are newly recorded for the Dominican Republic: Caribbomerus decoratus (Zayas), Caribbomerus elongatus (Fisher), and Caribbomerus asperatus (Fisher). The first two also represent first records for Hispaniola. Caribbomerus elongatus (Fisher) is redescribed based on additional material, including the first known males. Caribbomerus similis (Fisher) is newly rec...

Reputations are a ubiquitous feature of human social life, and a large literature has been dedicated to explaining the relationship between prosocial reputations and cooperation in social dilemmas. However, humans form reputations in domains other than prosociality, such as economic competency that could affect cooperation. To date, no research has evaluated the relative effects of multiple rep...

High levels of inheritable resistance to phosphine in Rhyzopertha dominica have recently been detected in Australia and in an effort to isolate the genes responsible for resistance we have used random amplified DNA fingerprinting (RAF) to produce a genetic linkage map of R. dominica. The map consists of 94 dominant DNA markers with an average distance between markers of 4.6 cM and defines nine ...

A cDNA encoding subunit Va of cytochrome c oxidase (EC 1.9.3.1) was cloned and characterized from a lesser grain borer (Rhyzopertha dominica) cDNA library. The complete cDNA consists of 693-bp and contains an open reading frame of 450-bp that encodes 150 amino acid residues. The sequence includes a 28-bp putative N-terminal and a 122-bp putative mature protein. The estimated molecular weight an...

The reproductive biology of Fidiobia dominica Evans (Hymenoptera: Platygastridae) was studied in the laboratory (25.6 +/- 1 degrees C) using host eggs of Diaprepes abbreviatus L. (Coleoptera: Curculionidae). F. dominica readily parasitized D. abbreviatus eggs on both host plant and wax paper substrates. The number of egg masses parasitized and the number of offspring produced were higher when f...

We used PCRs with omp A primers to determine if spotted fever group rickettsiae occurred in Amblyomma variegatum from 6 Caribbean islands. Positive amplicons were obtained from ticks from the U.S. Virgin Islands (9/18; 50%), Dominica (39/171; 30%), Montserrat (2/5; 40%), Nevis (17/34; 50%), St. Kitts (46/227; 20%), and St. Lucia (1/14; 7%). Sequences for a convenience sample of reaction product...

El objetivo de este artículo es sacar a la luz figura Sor Constanza Castilla (s. XV), una las primeras traductoras en lengua castellana. Esta monja dominica un ejemplo cómo esa época mujeres pudieron acceder nivel cultural desde el que se iniciaron como escritoras y traductoras, dentro vida monacal seno aristocracia. Castilla, linaje real ascendencia alemana, fue influyente poderosa priora que,...
