Development of allele-specific loop-mediated isothermal amplification (AS-LAMP) to detect the tebufenozide-resistant allele in the smaller tea tortrix, Adoxophyes honmai (Lepidoptera: Tortricidae)
The smaller tea tortrix, Adoxophyes honmai Yasuda (Lepidoptera: Tortricidae), is one of the most common pests that affect the tea plant, Camellia sinensis (L.) O. Kuntze. Diacylhydrazine-analog insect growth regu...

Identification of novel genes expressed highly and selectively in the corpora allata of the silkworm, Bombyx mori (Lepidoptera: Bombycidae)
Juvenile hormone (JH) has crucial roles in insect physiology, including development, reproduction, and polyphenism. JH is synthesized in the corpora allata (CA) from acetyl-CoA through 13 enzymatic steps, whic...

Open AccessGenome-wide Identification of Tebufenozide Resistant Genes in the smaller tea tortrix, Adoxophyes honmai (Lepidoptera: Tortricidae)
The smaller tea tortrix, Adoxophyes honmai, has developed strong resistance to tebufenozide, a diacylhydrazine-type (DAH) insecticide. Here, we investigated its mechanism by identifying genes responsible for the ...

Functional characterization of two paralogous JH receptors, methoprene-tolerant 1 and 2, in the silkworm, Bombyx mori (Lepidoptera: Bombycidae)
Methoprene-tolerant (Met) is a bHLH-PAS transcription factor that functions as a core component of juvenile hormone (JH) receptors in insects. The genome of the silkworm, Bombyx mori (L.), encodes two Met paralog...

Open AccessA Halloween gene noppera-bo encodes a glutathione S-transferase essential for ecdysteroid biosynthesis via regulating the behaviour of cholesterol in Drosophila
In insects, the precise timing of moulting and metamorphosis is strictly guided by ecdysteroids that are synthesised from dietary cholesterol in the prothoracic gland (PG). In the past decade, several ecdyster...

Open AccessCloning, phylogeny, and expression analysis of the Broad-Complex gene in the longicorn beetle Psacothea hilaris
Seven isoforms of Broad-Complex (PhBR-C), in which the sequence of the zinc finger domain differed (referred to as Z1, Z2, Z3, Z2/Z3, Z4, Z5/Z6, and Z6, respectively), were cloned from the yellow-spotted longicor...

Development of a cell-based assay for ecdysteroid quantification using an early ecdysteroid-inducible gene promoter
Ecdysteroids, primarily 20-hydroxyecdysone (20E) and ecdysone (E), are steroid hormones that regulate various developmental and physiological processes in insects. Commonly, immunoassays are used to quantify e...

Remodeling of the corpora cardiaca and the corpora allata during adult metamorphosis in Bombyx mori: identification of invisible corpora cardiaca by the expression of adipokinetic hormone
It is problematic to identify the corpora cardiaca (CC) of pupal and adult stages of Bombyx mori because of the presence of tissues similar in appearance near the associated corpora allata (CA). To find the CC, w...
