Fish and amphibians as test organisms for evaluation of effects caused by chemicals [PDF]

open access: yes, 2007
A large number of chemicals can contaminate aquatic environments and therefore be exposed to fish and amphibians during their sensitive stages of development.

The transformer gene controls sexual development in Drosophila suzukii

open access: yesInsect Science, EarlyView.
The transformer gene plays a key role in the genetic pathway for sexual development in Drosophila suzukii Abstract The genetic network of sex determination in the model organism Drosophila melanogaster was investigated in great detail. Such knowledge not only advances our understanding of the evolution and regulation of sexual dimorphism in insects ...

Multilocus sequence typing of the invasive pest Halyomorpha halys (Hemiptera: Pentatomidae) and associated endosymbiont reveals unexplored diversity

open access: yesInsect Science, EarlyView.
A multilocus sequence typing approach is proposed to explore Halymorpha halys genetic diversity, taking into consideration both insect nuclear markers and markers from the gut symbiont “Candidatus Pantoa carbekii.” Increased information was revealed regarding the number of distinct holobiont haplotypes in native and invasive populations of the pest ...

Thiamethoxam impairs honey bee visual learning, alters decision times, and increases abnormal behaviors. [PDF]

open access: yes, 2020
Learning is important for honey bee fitness and the pollination services that they provide. Neonicotinoid pesticides impair learning, fitness, colony health, and pollination, but most studies on how they affect bee learning have focused on olfactory ...

Genetic engineering for SIT application: a fruit fly‐focused review

open access: yesInsect Science, EarlyView.
Abstract Sterile insect technique (SIT) has become a key component of efficient pest control. Fruit fly pests from the Drosophilidae and Tephritidae families pose a substantial and overwhelmingly increasing threat to the agricultural industry, aggravated by climate change and globalization among other contributors.

National assessment of bioavailable contamination level using caged Gammarus fossarum (Crustacean): towards optimisation and extension of the list of monitored substances

open access: yesEnvironmental Sciences Europe
Background Since 2018, in situ caging of Gammarus fossarum has been used by French water agencies at more than 400 river sites. This active biomonitoring tool helps meet the requirements of the Water Framework Directive by analysing priority substances ...

Genetic differentiation and adaptive evolution of buff‐tailed bumblebees in Asia

open access: yesInsect Science, EarlyView.
This study investigates the genetic differentiation and local adaptation of the buff‐tailed bumblebee (Bombus terrestris) across its European and Asian populations. Using whole‐genome resequencing, we identified distinct genetic differences between populations, with Asian B. terrestris representing a unique genetic resource.

Functional validation of a white pupae minimal gene construct in Ceratitis capitata (Diptera: Tephritidae)

open access: yesInsect Science, EarlyView.
An intronless version of the white pupae (wp) gene was engineered to restore the wild type brown puparium color in white pupae phenotype mutants of the Mediterranean fruit fly, Ceratitis capitata. Functionality of the minimal gene version (mini‐wp) was verified in vivo, as one copy of mini‐wp successfully restored the wild type phenotype in homozygous ...
