Article Abstract

Tool-use in animals is a complex and rare phenomenon, particularly in insects. Tool-use in assassin bugs has been suggested as several species apply adhesive plant resins to their body, which has been hypothesized to function in enhancing prey capture. Here, we staged predatory interactions of resin-deprived and resin-equipped assassin bugs ( sp.) and discovered that applying resin as a tool conveys a clear predatory advantage to the assassin bugs. sp. can thus be considered a tool-user, and since this behaviour was present in all individuals, including newly hatched nymphs, tool-use can be considered to be stereotyped. Our study, along with others, suggests that, when compared with other insects, tool-use is disproportionately common within the assassin bugs.

Chagas disease is caused by , which is transmitted to mammals, including humans, mainly by insects of the subfamily Triatominae (Hemiptera: Reduviidae). Also known as "kissing bugs", the subfamily includes 159 species in 18 genera and five tribes. Although most species are in the Americas, here we present the first compilation of non-American triatomine occurrences.

Background: Plasticity in sensory perception and tolerance to xenobiotics contributes to insects' adaptive capacity and evolutionary success, by enabling them to cope with potentially toxic molecules from the environment or internal milieu. Odorant-binding proteins (OBPs) and chemosensory proteins (CSPs) have traditionally been studied in the context of chemoreception. However, accumulating evidence over the past few years indicates that these protein families can also sequester insecticide molecules.

The two closely related Oriental species of the genus , (Stål, 1867) and (Fabricius, 1787), exhibit remarkable morphological similarity, particularly in their overall red and black body coloration, including the head, thorax, and abdomen. Based on the examination of type specimens and non-type material collected from various localities of southern China, we found these two congeners were misidentified in many previous publications. Due to the restricted distribution and limited population size of in China, most taxonomic, biological, and biocontrol studies conducted under the name or should be instead attributed to To address this confusion regarding these two species, the present study clarifies the taxonomic status of the two controversial species- and .

Lack of Genetic Differentiation of Five Triatomine Species Belonging to the Subcomplex (Hemiptera, Reduviidae).

The subcomplex, comprising several triatomine species, plays a significant role in the transmission of Chagas disease in southern Brazil. Despite morphological distinctions among these species, their genetic differentiation remains poorly understood, particularly in sympatric regions. This study investigates the genetic diversity and phylogenetic relationships through DNA sequencing analysis of five sympatric species within the subcomplex (, , , , and ), using a 542-bp fragment of the mitochondrial cytochrome b (mtCytb) gene.

Background: The genetic diversity of Trypanosoma cruzi and the epidemiological characteristics of the environments in which the parasite occurs are essential for understanding infection dynamics and controlling Chagas disease. This systematic review aimed to: (i) identify and analyze studies that evaluated the genetic variability and epidemiological aspects of T. cruzi infection in the state of Rio Grande do Norte, Brazil; (ii) summarize the information reported in the literature; and (iii) suggest new control strategies tailored to the region's epidemiological profile.
