Discovery of an aquaporin (CrAQP2) in the freshwater larval midge, Chironomus riparius and its role in response to road de-icers
Chironomus riparius midge larvae are ubiquitous in freshwater ecosystems throughout the Northern Hemisphere. Recently, freshwater in temperate regions has experienced a threat from salinization due to the use of road de-icers. As ambient temperatures fluctuate, snow and ice melt carry the de-icers…

Effects of PFOS on the behavior, growth, emergence, and predation susceptibility of larval mosquitoes (Culex quinquefasciatus)
Per-/polyfluoroalkyl substances (PFAS) have been commonly used over several decades for a variety of products and are very persistent in the environment. However, not much is known about their direct effects on aquatic invertebrates and their ecosystems. We examined the survival, behavior…

Parental thermal environment affects offspring resilience to winter and spring weather anomaliesDryadData supporting this study are available on Dryad:
Recent increases in the frequency and intensity of thermal anomalies can result in recurrent stressful weather events. Among annual insects, this phenomenon may expose parents and offspring to a succession of different weather anomalies (e.g. summer heatwaves and late spring frosts). Parental…

Rp-vasa: a bona fide primordial germ cell marker that drives embryonic expression in the Chagas disease vector Rhodnius prolixus
Rhodnius prolixus is an insect vector of the protozoan Trypanosoma cruzi, the causative agent of debilitating Chagas disease, which is transmitted to humans during blood feeding. Identifying germline markers is a critical step in advancing vector control and transgenic technologies of these…

Distinct roles of the Anopheles gambiae Imd/Rel2 and Toll/Rel1 pathways in resistance to systemic bacterial and fungal infections
In the malaria vector Anopheles gambiae s.l. Toll and Imd immune pathways signal through Re1l and Rel2 NF-κB transcription factors, respectively. Toll/Rel1 and Imd/Rel2 have been characterized mostly in the context of defense against malaria parasites, exhibiting Plasmodium species-specific roles…

Involvement of Taiman in juvenile hormone signaling controlling sexual maturation in a male moth
In insects, juvenile hormone (JH) is essential for orchestrating reproductive events. For example, in the male moth Agrotis ipsilon, the behavioral response to female sex pheromone is linked to neuronal sensitivity in the primary olfactory centers (antennal lobes, ALs), and the maturation of…

mir-31 mediated control of bacteriome size in tsetse flies
Tsetse flies are the primary vectors of African trypanosomes, which are transmitted through blood feeding. To supplement this nutritionally limited diet, tsetse evolved an obligate mutualism with the bacterium Wigglesworthia glossinidia, housed within a specialized organ called the bacteriome…

Isolation of extracellular vesicles from insect hemolymph
Extracellular vesicles (EVs) are produced by cells of all domains of life and current research shows their involvement in intercellular transfer of information. However, a major drawback to the progress of the field relates to the fact that isolating pure EV fractions from complex biofluids is a…

The fallacy of the integrated pest management paradigm and the need for its OFF seasonal shift in the management of tropical fruit flies (Diptera: Tephritidae): The case of Ceratitis capitata
The Mediterranean fruit fly (medfly) is a serious frugivorous Afro-tropical pest common in the Mediterranean Region in Europe, which, despite the requirements of Directive 2009/128/EC and the availability of biological methods, is still widely controlled using pesticides.Our objective was to…

Temperature-dependence of life history in an edible cricket: Implications for optimising mass-rearing
Optimisation of life history and organismal performance underlies success in insect mass-rearing. Rearing schedules, resource use and production yield depend on many aspects of insect fitness and performance within and across generations, such as growth, development, longevity, and fecundity, which…

The Drosophila adult brain: short overview of structure, function, and resources Graphical Review Paper
This short review is targeted at researchers new to the Drosophila model (thereafter: a Drosophilist) in the field of neuroscience. We aim to provide an introductory overview of our current understanding of the adult Drosophila melanogaster (thereafter: Drosophila) brain, its structures, circuitry…

Experimental adaptation to singular pathogen challenge reduces susceptibility to novel pathogens in Drosophila melanogaster
Hosts often encounter and must respond to novel pathogens in the wild, that is pathogens that they have not encountered in recent evolutionary history, and therefore are not adapted to. How hosts respond to these novel pathogens and the outcome of such infections can be shaped by the host's…

The trypanosomatid (Kinetoplastida: Trypanosomatidae) parasites in bees: A review on their environmental circulation, impacts and implications
Trypanosomatids, obligate parasites capable of impacting insects' hindgut, have recently obtained considerable attention, especially about their effects on bees. While Crithidia mellificae and C. bombi were initially discovered and studied in honey bees and bumblebees, respectively, molecular…

Consequences of “zombie-making” and generalist fungal pathogens on carpenter ant microbiota
The bacterial microbiome of the ant Camponotus floridanus has been well characterized across body regions and maturation levels. However, potential effects of entomopathogens on the gut microbiome, and the fungal communities therein, are yet to be assessed. Additionally, the mycobiome remains often…

A model that integrates the different piRNA biogenesis pathways based on studies in silkworm BmN4 cells
PIWI-interacting (pi) RNAs play an essential role in protecting the genomic integrity of germ cells from the disruptive transpositions of selfish genetic elements. One of the most important model systems for studying piRNA biogenesis is the ovary derived BmN4 cell line of the silkworm Bombyx mori…

Antioxidants, oxidative stress and reactive oxygen species in insects exposed to heat
In response to high temperatures, insect metabolic rates increase, favoring the release of higher amounts of reactive oxygen species (ROS). These ROS need to be counteracted by antioxidants to avoid oxidative stress, which can lead to cell damage and death. In this manuscript, we review evidence in…

The multifaceted role of brood communication in wasp societies
The family Vespidae represents a key group to understand the evolutionary trajectory of social behavior in insects, as these wasps display the entire spectrum of social behaviors, from solitary to highly eusocial. The evolution of eusociality likely depended on a coordinated communication system…

Thermal effects on metabolic rate in diapausing Pieris rapae butterflies
ABSTRACT: As ectotherms, many insects spend the winter months in a state of suspended animation (i.e., diapause), lowering their metabolic rates to subsist on a limited store of energy reserves. The ability to lower metabolic rate during diapause relies, in part, on cold winter temperatures to…

Molecular mechanisms and comparative transcriptomics of diapause in two corn rootworm species (Diabrotica spp.)
Diapause is a programmed developmental arrest that can occur at any developmental stage depending on species, but the mechanisms that underscore embryonic diapause are poorly understood. Here, we identified molecular mechanisms underscoring distinct phases of diapause in the Diabrotica spp…

Exploring novel pyrethroid resistance mechanisms through RNA-seq in Triatoma dimidiata from Colombia
Pyrethroids are the most widely used insecticides for controlling insect vectors carrying medically and economically significant pathogens. In Colombia, studies on triatomine insecticide resistance are limited. Due to the increasing challenge of insecticide resistance, this work focuses on…
