Environmental Morphological Divergence and Its Integration With Collective Behavior in Cooperative Pseudoscorpions

Ethology, EarlyView.
In the social pseudoscorpion Paratemnoides nidificator, populations across contrasting urban and peri‐urban environments exhibit marked morphological divergence and consistent sexual dimorphism. Crucially, relative development of the prey‐capture pedipalp apparatus (rather than absolute body size) is positively integrated with proactive collective ...

Simultaneous Infection With Genetically Distinct Trypanosoma cruzi Isolates Is Associated With Distinct Myocardial Innate Immune Transcriptional Profiles During Acute Infection in Mice

Parasite Immunology, Volume 48, Issue 10, October 2026.
ABSTRACT Innate immune receptors are central to host resistance against Trypanosoma cruzi infection, yet how parasite genetic diversity is associated with these responses remains poorly understood. Here, we characterized acute infection outcomes and myocardial innate immune transcriptional profiles in mice subjected to single and mixed infections with ...

Temporal change of the aggregation response in Triatoma infestans [PDF]

Memórias do Instituto Oswaldo Cruz, 2000
Adults and larvae of Triatoma infestans spend daylight hours assembled in shaded places. An assembling factor has been demonstrated in the excrement of this species. We analysed different aspects of the dynamics of the response of bugs. Recently fed insects do not aggregate around faeces.

Topographic Barriers and Lowland Corridors Structure Gene Flow in the Chagas Vector Rhodnius pallescens Across the Isthmian Forests

Journal of Biogeography, Volume 53, Issue 7, July 2026.
ABSTRACT Aim Biogeographic processes can profoundly shape the connectivity and evolutionary potential of arthropod disease vectors. We investigated how Panama's ecological and topographic transitions structure populations of the kissing bug Rhodnius pallescens, the primary vector of the Chagas disease agent Trypanosoma cruzi in the region.

Variations of the External Male Genitalia in Three Populations of Triatoma infestans Klug, 1834 [PDF]

, 1998
Triatoma infestans is the triatomine that presents the greatest dispersion area in South America. However, it is not known whether the original characteristics of this insect remained in its long dispersion process.

Metaciclogênese do Trypanosoma cruzi como parâmetro de interação do parasita com o triatomíneo vetor

Revista da Sociedade Brasileira de Medicina Tropical, 1997
Triatoma infestans infectados por três amostras do Trypanosoma cruzi permitiram observar: 1) variabilidade numérica de metacíclicos obtidos de cada amostra após diferentes períodos de infecção; 2) diferenças na perda da infecção de acordo com a amostra ...

The Contribution of Entomological Surveillance to the Control of Chagas Disease in Endemic Regions: An Integrative Literature Review

Tropical Medicine &International Health, Volume 31, Issue 7, Page 832-842, July 2026.
ABSTRACT Chagas disease remains a significant public health challenge in various endemic regions of Latin America. The persistence of vector‐borne transmission highlights the complexity of the issue and the limitations of traditional strategies. In this context, entomological surveillance plays a strategic and multifaceted role, not only in the early ...

Diel thermal variability does not always have detrimental effects on the performance of ectotherms

Functional Ecology, Volume 40, Issue 4, Page 786-799, April 2026.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Climate change directly affects animal survival, with ectotherms being particularly vulnerable because their vital rates are closely related to environmental temperatures.
