Silencing of juvenile hormone‐related genes through RNA interference leads to molt failure and high mortality in the spongy moth

open access: yesInsect 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 ...

MICROHARDNESS DIFFERENCES BETWEEN SILK FIBER AS A NATURAL FILLER COMPOSITE RESIN WITH NANOFILLER COMPOSITE RESIN

open access: yesODONTO: Dental Journal, 2020
Background: Dental composite composed of natural filler is a trend nowadays. Silk fiber, Bombyx mori L., is one of the natural fibers that have good microhardness (66 VHN) and has a potency to become a renewable natural filler.

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.

Роль сомы в формировании способности к термическому партеногенезу у тутового шелкопряда Bombyx mori L. [PDF]

open access: yes, 2009
The eggs that have undergone the impact of anticipating heat shock (water at 46°C during 1 min) and consequent ovary transplantation in course of larval development were studied.

Photoperiod-modulated instar-specific clock-shifting in the circadian protein and amino acid rhythms in the larval segmental muscle of Bombyx mori [PDF]

open access: yes, 2011
The photoperiod-modulated clock-shifting in the circadian protein rhythm was studied in the segmental muscle of Bombyx mori. The analysis of phase response curves of the fourth instar rhythm revealed that the muscle tissue completes six protein synthetic

Selection, counterselection, and conditional gene expression for genetic biocontrol of insects

open access: yesInsect Science, EarlyView.
Selection, counterselection, and conditional expression can be used for sex separation. Selection (S) and counterselection (CS) genes are linked to the sex chromosomes (e.g., the X and Y chromosomes) to confer sex‐specific selection or counterselection based on the presence or absence of the S or CS genes.

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

Okaramine insecticidal alkaloids show similar activity on both exon 3c and exon 3b variants of glutamate-gated chloride channels of the larval silkworm, Bombyx mori [PDF]

open access: yes, 2017
The okaramine indole alkaloids were recently shown to be more selective than ivermectin in activating the glutamate-gated chloride channels of the silkworm larvae of Bombyx mori (BmGluCls).

New Allergens Approved by the WHO/IUIS Allergen Nomenclature Sub‐Committee in 2021–2024 and Their Significance for Future Diagnostics, Regulation, and Research. An EAACI Task Force Report

open access: yesAllergy, EarlyView.
ABSTRACT The WHO/IUIS Allergen Nomenclature Sub‐Committee is an international body of experts that maintains the systematic nomenclature of allergenic proteins by assigning official names to newly identified allergens submitted by researchers. Here, we summarize the data on new allergens approved between 2021 and 2024.

The complete mitochondrial genome of a balanced sex-linked lethal silkworm and its phylogenetic analysis

open access: yesMitochondrial DNA. Part B. Resources, 2019
Male-only rearing has long been desirable in sericulture because males have superior economic characteristics. To this end, a balanced sex-linked lethal (BSL) system has been developed.
