Intestinal Fork Head Regulates Nutrient Absorption and Promotes Longevity
Cell Reports, 2017 Reduced activity of nutrient-sensing signaling networks can extend organismal lifespan, yet the underlying biology remains unclear. We show that the anti-aging effects of rapamycin and reduced intestinal insulin/insulin growth factor (IGF) signaling (IIS)

Insect Science, EarlyView.The feasibility of using RNA interference to control the globally important quarantine pest, the spongy moth. Targeting genes related to JHs play an important role in the growth and development of insects. First, the open reading frames (ORFs) of Ldjhamt and Ldjheh were identified and characterized, and the target genes were cloned and double‐stranded ...

Permeability of lepidopteran larval midgut to the potential insecticidal peptides proctolin and TMOF
, 2008 Great efforts have been recently devoted to the identification of innovative gene products to be developed as biopesticides. A large number of studies constantly detect new naturally derived peptides and proteins with haemocoelic receptors that could be ...

Dual role of BMP signaling in the regulation of Drosophila intestinal stem cell self-renewal
Fly, 2017 Many adult organs including Drosophila adult midguts rely on resident stem cells to replenish damaged cells during tissue homeostasis and regeneration.

Maltase 1 regulates DENV2 infection and life history in Aedes aegypti
Insect Science, EarlyView.Our study employed CRISPR/Cas9 to generate a MAL1 knockout strain of Aedes aegypti, demonstrating that the absence of MAL1 significantly suppresses DENV2 replication in the midgut and impairs viral transmission. The mutation also altered life‐history (hatching/pupation/emerging rates and sex‐specific survival), identifying MAL1 as a novel target for ...

Tick-borne pathogen detection in midgut and salivary glands of adult Ixodes ricinus
Parasites & Vectors, 2018 The tick midgut and salivary glands represent the primary organs for pathogen acquisition and transmission, respectively. Specifically, the midgut is the first organ to have contact with pathogens during the blood meal uptake, while salivary glands along

Iflaviruses in arthropods: when small is mighty
Insect 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
Insect 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
