Ecological host fitting of Trypanosoma cruzi TcI in Bolivia: mosaic population structure, hybridization and a role for humans in Andean parasite dispersal. [PDF]

open access: yes, 2015
An improved understanding of how a parasite species exploits its genetic repertoire to colonize novel hosts and environmental niches is crucial to establish the epidemiological risk associated with emergent pathogenic genotypes.

The magnitude of cryptic insect diversity in one tropical rainforest

open access: yesInsect Conservation and Diversity, Volume 18, Issue 6, Page 1163-1174, November 2025.
We detected 214 cryptic species out of a total of 2006 species (10.6%) examined from 22 focal insect taxa in 1500 ha tropical rainforest in Panama. The percentage of cryptic species varied greatly among assemblages (0%–19%), with half of the assemblages devoid of cryptic species and the highest proportions of cryptics in Pieridae and Formicidae ...

Field trials of an improved cost-effective device for detecting peridomestic populations of Triatoma infestans (Hemiptera: Reduviidae) in rural Argentina [PDF]

open access: yes, 2002
An improved device for detecting peridomestic Triatoma infestans consisting of one-liter recycled Tetra Brik milk boxes with a central structure was tested using a matched-pair study design in two rural areas in Argentina.

The loss of the urea cycle and ornithine metabolism in different insect orders: An omics approach

open access: yesInsect Molecular Biology, Volume 34, Issue 5, Page 632-644, October 2025.
Among urea cycle enzymes, only the nitric oxide synthase gene is universally present across insect genomes. All Hemiptera species lack the enzymes needed to convert citrulline to arginine, and some also lack the pathway from arginine to ornithine. Putrescine and spermidine synthesis is conserved in all insects, but aphids lack the capability to produce

Chromosome complement and meiosis in three species of the Neotropical bug genus Antiteuchus (Heteroptera, Pentatomidae, Discocephalinae) [PDF]

open access: yes, 2006
Orcein staining of spermatocytes was used to study the meiotic behavior of holocentric chromosomes in three member of the genus Antiteuchus (commonly known as stink bugs). We describe and illustrate the karyotype of Antiteuchus mixtus, A. sepulcralis and
