The mitochondrial genome of the Maltese honey bee, Apis mellifera ruttneri (Insecta: Hymenoptera: Apidae)

open access: yesMitochondrial DNA. Part B. Resources, 2020
The mitochondrial genome of Apis mellifera ruttneri consisted of 13 protein-coding genes, two rRNAs, 22 tRNAs, an AT-rich control region, and was 16,577 bp long. The phylogenetic analyses suggested that A. m.

Iflaviruses in arthropods: when small is mighty

open access: yesInsect Science, EarlyView.
Many arthropod species harbor iflaviruses, which often cause covert (asymptomatic) infections, but may still affect host fitness. We review the impact of iflaviruses on arthropod fitness, immunity, behaviour as well as the iflavirus’ host range, transmission, tissue tropism and the interactions with other microorganisms within arthropods.

Sensitivity and Resistance of Parasitic Mites (Varroa destructor, Tropilaelaps spp. and Acarapis woodi) Against Amitraz and Amitraz-Based Product Treatment: A Systematic Review

open access: yesInsects
Resistance to amitraz in Varroa destructor mites poses a significant challenge to global beekeeping, leading to the declining efficacy of treatments and increased colony losses. This study aims to comprehensively map, characterize, and analyze the status

The complete mitochondrial genome of Apis mellifera jemenitica (Insecta: Hymenoptera: Apidae), the Arabian honey bee

open access: yesMitochondrial DNA. Part B. Resources, 2020
The mitochondrial genome of a worker Apis mellifera jemenitica was 16,623 bp. It consisted of 13 protein-coding genes, 22 transfer RNAs, two ribosomal RNAs and a control region. Phylogenetic analyses suggest a close relationship between A. m. jemenitica,

Rapid hormonal rise in honey bees due to heat‐shock is mitigated by a primer pheromone

open access: yesInsect Science, EarlyView.
We show that honey bee foragers increased juvenile hormone (JH) titers significantly after heat‐shocked for 1 h at 40 °C, but this increase is dependent on social conditions. Increase of JH titers only happened when bees were isolated (one worker bee per vial) but not in groups.

Chronic Exposure to Field-Level Thiamethoxam Impairs Gut Tissue and Reduces Honeybee (Apis cerana) Survival

open access: yesInsects
Pesticides such as neonicotinoids frequently harm beneficial insect pollinators and affect their survival, social behavior, digestive system, and metabolism.

Effect of the microbiome on pathogen susceptibility across four Drosophilidae species

open access: yesInsect Science, EarlyView.
Four Drosophilidae species were used to investigate how variation in the host microbiome influences susceptibility to infection. Microbial composition and abundance differed among species and treatments. The effects of microbiome manipulation on host survival were both species‐ and pathogen‐specific.

A horizontally acquired pantothenate gene drives vitellogenin's benefit to whitefly symbiosis persistence

open access: yesInsect Science, EarlyView.
This diagram illustrates that the horizontally transferred panBC influences the level and localization of vitellogenin (Vg) by facilitating pantothenate production and juvenile hormone (JH) biosynthesis. In turn, Vg shields symbionts by suppressing autophagic degradation in bacteriocytes.

Decades of Enclosure Protection Exert Composite Effects on Grassland Grasshopper Communities

open access: yesIntegrative Zoology, EarlyView.
Decades of enclosure protection have altered grasshopper community structure, with species‐specific effects on population dynamics. For the low‐mobility grasshopper Chorthippus fallax, abundance did not differ strongly between exclosure‐protected and overgrazed areas, but its egg development duration was longer in exclosures. The two C.
