Genetic Diversity and Phylogenetic Relationships of Coevolving Symbiont-Harboring Insect Trypanosomatids, and Their Neotropical Dispersal by Invader African Blowflies (Calliphoridae)

Frontiers in Microbiology, 2018
This study is about the inter- and intra-specific genetic diversity of trypanosomatids of the genus Angomonas, and their association with Calliphoridae (blowflies) in Neotropical and Afrotropical regions. Microscopic examination of 3,900 flies of various

Antagonistic effects of intraspecific cooperation and interspecific competition on thermal performance

eLife, 2020
Understanding how climate-mediated biotic interactions shape thermal niche width is critical in an era of global change. Yet, most previous work on thermal niches has ignored detailed mechanistic information about the relationship between temperature and

An inquiry‐based activity to teach about insects of medico‐legal importance: Lessons from Redi's landmark experiment

Natural Sciences Education, Volume 55, Issue 1, June 2026.
Abstract In this article, we describe an inquiry‐based teaching activity developed in a public high school in Brazil. The objectives were to (a) develop an experimental activity grounded on the students’ autonomy for formulating and testing hypotheses, (b) address Biology topics from a historical and multidisciplinary perspective, (c) stimulate skills ...

Armadilha atrativa padronizada e de baixo custo para coleta de Diptera (Insecta) atraídos por substratos proteicos

Entomological Communications
The use of baited traps is essential for sampling necrophagous Diptera Linnaeus, 1758 in both ecological and forensic studies. Ferreira's trap is a widely used model in Brazil; however, traditional versions can present logistical challenges under field ...

Hairy, hairy quite contrary: Pollination and functional floral traits in a hirsute carrion‐scented stapeliad

TAXON, Volume 75, Issue 3, June 2026.
Abstract Floral mimicry of decaying substrates of animal origin, such as carrion or faeces, is associated with unusual traits such as geoflory, deep maroon or yellow colouration, floral hairs and unpleasant odour, but the functional significance of these traits for attracting and manipulating pollinators has seldom been examined.

Chasing behaviour and optomotor following in free-flying male blowflies: flight performance and interactions of the underlying control systems

Frontiers in Behavioral Neuroscience, 2010
The chasing behaviour of male blowflies after small targets belongs to the most rapid and virtuosic visually guided behaviours found in nature. Since in a structured environment any turn towards a target inevitably leads to a displacement of the entire ...

Multiparasitism Resolves the Apparent Paradox of High Male Pheromone Investment Despite Frequent Within‐Host Mating in a Parasitoid

Entomologia Experimentalis et Applicata, Volume 174, Issue 6, Page 579-588, June 2026.
It is unknown why males of the parasitoid wasp Nasonia giraulti produce large amounts of a costly sex pheromone although they were long thought to mate with their females already before emergence within the host. Mated females do no longer respond to the pheromone.

Stability of positive solutions of local partial differential equations with a nonlinear integral delay term

Electronic Journal of Qualitative Theory of Differential Equations, 2008
Stability properties of positive stationary solutions to local partial differential equations with delay are studied. The results are applied to equations with not necessarily convex (concave) nonlinearities, for example, to the diffusive Nicholson's ...

A Comparative Study of iDNA and airDNA for Biodiversity Assessments in Tropical Forest Fragments

Environmental DNA, Volume 8, Issue 3, May–June 2026.
Comparing invertebrate‐derived DNA and airborne eDNA across fragmented tropical forests, we show that iDNA recovers higher vertebrate richness from fewer samples, while airDNA offers greater field reliability. Together, both methods capture functional diversity gradients, supporting a combined approach for agroforestry biodiversity monitoring ...
