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 ...

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.

Calcitonin‐like diuretic hormone influences reproduction in adult female Rhodnius prolixus

open access: yesInsect Science, EarlyView.
Highlights • CT/DH‐like immunoreactivity is present in female reproductive tissues • CT/DH receptor transcripts are expressed in the fat body and ovaries • RNAi knockdown of CT/DH receptors reduces egg number and hatching rate • Rhopr‐CT/DH increases RhoprVg1 and RhoprVgR expression in ovaries in vitro • Rhopr‐CT/DH stimulates oviduct contractions in a

Adaptation of the invasive pest Drosophila suzukii to a specialized nutritional niche

open access: yesInsect Science, EarlyView.
Unlike most Drosophila larvae that feed on spoiled food, Drosophila suzukii larvae thrive on ripening fruits and consequently face a low‐protein, high‐carbohydrate nutritional challenge. Comparisons of growth among D. suzukii, D. biarmipes, and D. melanogaster larvae across diets with varying protein‐to‐carbohydrate ratios demonstrate that D.

Two Entomophagous Isolated From Sumatera Utara; Potential as Biocontrol Agent Againts Nematode [PDF]

open access: yes, 2016
Two species of nematophagous fungi has been isolated from Sumatera Utara soil, with an aim of harnessing their potential in the biological control of plant parasitic nematodes or animal parasitic nematodes in Indonesia, especially in Sumatera Utara. Soil

Human behaviors: a threat for mosquito control?

open access: yes, 2015
Community involvement and the preventive behavior of households are considered to be at the heart of vector-control strategies. In this work, we consider a simple theoretical model that enables us to take into account human behaviors that may interfere ...

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.

Volatile organic compounds emitted from fungal-rotting beech (Fagus sylvatica) [PDF]

open access: yes, 2008
Chemo-communication is an important mode of interaction within ecosystem. The living organism in the ecosystem can deliver signals to conspecifics, to co-organisms, and unintentionally to their enemies, by emitting the volatile organic compounds (VOCs ...

Unravelling Evolutionary Dynamics of Female Sexual Cannibalism and Male Reproductive Strategies in Spiders

open access: yesIntegrative Zoology, EarlyView.
Sexual cannibalism (SC), where one mating partner consumes the other in the context of mating, is especially prevalent among spiders. However, the evolution of SC in spiders is still not fully understood. We review key hypotheses for SC and explore how female‐initiated SC has driven the evolution of various male counter‐adaptations to mitigate its ...

Comparison of Three Sympatric Desert Lizards: Digestive Tract Structure, Digestive Enzyme Activities, Gut Microbiota, and Metabolites

open access: yesIntegrative Zoology, EarlyView.
We performed 16S rDNA sequencing and metabolite profiling for three sympatric lizard species—Teratoscincus roborowskii, Phrynocephalus axillaris, and Eremias roborowskii—and compared their goblet cell and enzyme activities in the digestive tract. Our study suggests that the dietary niche may promote divergence or convergence of microbiota across host ...
