N < sup > 6 < /sup > -adenosine (m < sup > 6 < /sup > A) mRNA methylation is required for Tribolium castaneum development and reproduction
Insect Biochem Mol Biol. 2023 Jul 6;159:103985. doi: 10.1016/j.ibmb.2023.103985. Online ahead of print.ABSTRACTGene expression is regulated at various levels, including post-transcriptional mRNA modifications, where m6A methylation is the most common modification of mRNA. The m6A methylation regulates multiple stages of mRNA processing, including splicing, export, decay, and translation. How m6A modification is involved in insect development is not well known. We used the red flour beetle, Tribolium castaneum, as a model insect to identify the role of m6A modification in insect development. RNA interference (RNAi)-mediated...

Ovariole-specific Yellow-g and Yellow-g2 proteins are required for fecundity and egg chorion rigidity in the red flour beetle, Tribolium castaneum
In this study we investigated the function of two of this family's genes, yellow-g (TcY-g) and yellow-g2 (TcY-g2), on the formation and morphology of the eggshell of the red flour beetle, Tribolium castaneum. Real-time PCR analysis revealed that both TcY-g and TcY-g2 were specifically expressed in the ovarioles of adult females. Loss of function produced by injection of double-stranded RNA (dsRNA) for either TcY-g or TcY-g2 gene resulted in failure of oviposition. There was no effect on maternal survival. Ovaries dissected from those dsRNA-treated females exhibited ovarioles containing not only developing oocytes but also ...

A review of the molecular mechanisms of acaricide resistance in mites and ticks
Insect Biochem Mol Biol. 2023 Jun 28:103981. doi: 10.1016/j.ibmb.2023.103981. Online ahead of print.ABSTRACTThe Arachnida subclass of Acari comprises many harmful pests that threaten agriculture as well as animal health, including herbivorous spider mites, the bee parasite Varroa, the poultry mite Dermanyssus and several species of ticks. Especially in agriculture, acaricides are often used intensively to minimize the damage they inflict, promoting the development of resistance. Beneficial predatory mites used in biological control are also subjected to acaricide selection in the field. The development and use of new genet...
