Complete mitochondrial genome of Appasus japonicus Vuillefroy, 1864 (Hemiptera: Belostomatidae) [PDF]

Mitochondrial DNA. Part B. Resources, 2022
We describe the initial sequencing and assembly of the complete mitochondrial genome of Appasus japonicus Vuillefroy, 1864 (Hemiptera; Belostomatidae; Appasus). The mitochondrial genome of A. japonicus was found to be 18,608 bp.

The mitochondrial genome of a giant water bug Lethocerus deyrollei (Hemiptera: Belostomatidae) from South Korea [PDF]

Mitochondrial DNA. Part B. Resources, 2021
A giant water bug Lethocerus deyrollei (Hemiptera: Belostomatidae) is a large, predatory, and nocturnal hemipteran insect, which has been considered threatened and thus enrolled as an endangered species in South Korea and Japan.

Morphological and Molecular Identification of Lethocerus patruelis (Stål, 1854) (Hemiptera: Belostomatidae) Specimen Collected in Close Proximity to Humans in Southern Italy [PDF]

Insects
The Belostomatidae is a family of aquatic Heteropteran insects that normally inhabit swamps of tropical, subtropical and temperate regions where they naturally feed on a large range of prey, mainly fish, amphibians and reptiles. However, these arthropods

Reproductive Strategies in Paternal Care and Remarkably Low Paternity Level in a Giant Water Bug [PDF]

Ecology and Evolution
Reproductive strategies are crucial for organisms because they directly affect the organisms' fitness. “Parental care” is one of the strategies adopted by organisms to improve their fitness.

Assessing the Relationship Between Macroinvertebrate Metrics and Fine Sediment Index for Ecological Biomonitoring in the Little Akaki River, Addis Ababa, Ethiopia. [PDF]

Ecol Evol
Habitat quality had a positive correlation with percentage of Ephemeroptera, percentage of EOT, and Shannon diversity index (r = 0.833, r = 0.880, and r = 0.939, respectively). PSI had positive correlation with number of taxa, and ASPT‐ETHbios (r = 0.819, and r = 0.798, respectively). Most sites were heavily sedimented.

Range Expansion of the Giant Water Bug <i>Lethocerus patruelis</i> (Stål, 1854) in Europe. [PDF]

Ecol Evol
We modeled the expansion of the giant water bug, with a focus on niche dynamics and habitat suitability. Our results show evidence for an ongoing expansion, with strong potential for further spread under future climatic conditions. ABSTRACT Climate change is altering freshwater ecosystems, causing extinctions, range expansions, and facilitating ...

Sex on the Beach: Sexual Size Dimorphism Among Aquatic Bugs (Nepomorpha) Inhabiting Different Habitats. [PDF]

Ecol Evol
We examined the degree of sexual size dimorphism (SSD), based on body length, in approximately 45% of known water bug (Nepomorpha) species. Contrary to our initial hypothesis, we found that females are not significantly longer than males in most species. Our research revealed that habitat plays a significant role in SSD.

The Benefit of Maternal Care and Infanticide by Males as Reproductive Strategies in a Caprellid Amphipod. [PDF]

Ecol Evol
In the marine amphipod Caprella kominatoensis, males perform infanticide to terminate maternal care and accelerate female molting for mating opportunities. However, we found that maternal defense is effective when the female parent is larger than the intruding male.

Karyotype evolution in progress: A new diploid number in Belostoma candidulum (Heteroptera: Belostomatidae) from Argentina leading to new insights into its ecology and evolution

European Journal of Entomology, 2014
A novel chromosome complement (2n = 14 = 12 + XY/XX; male/female sex chromosomes), male meiosis behaviour, heterochromatin characterization, and frequency and distribution of chiasmata are described for the first time in specimens from a natural ...
