Molecular characterization of transformer, transformer‐2, and doublesex genes in the carambola fruit fly, Bactrocera carambolae, revealing potential for genetic pest management

Insect Science, EarlyView.
Abstract Globalization and climate change may be driving the spread of the quarantine fruit fly, Bactrocera carambolae, highlighting the need for ecofriendly control methods like the Sterile Insect Technique (SIT), which relies on releasing sterile males to reduce wild populations.

Molecular mechanisms of sex determination in Lepidoptera: current status and perspectives

Insect Science, EarlyView.
The genetic basis of sex determination in Lepidoptera was discovered in 2014 in the silkworm Bombyx mori. In this model species, the W chromosome‐derived small piRNA called Fem piRNA downregulates the expression of a Z‐linked gene, Masculinizer (Masc), which leads to the default female‐specific splicing of the doublesex gene (dsxF) and thus to female ...

Russian wheat aphid: a model for genomic plasticity and a challenge to breeders

Insect Science, EarlyView.
Invasive foundress finds suitable habitat and reproduces through pathogenesis. Wingless females produce life offspring quickly, which leads to high population densities. High population densities result in competition, which may induce epigenetic changes and wing development for dispersal.

The shibirets4 mutation causes temperature sensitive paralytic and lethal phenotypes in the Queensland fruit fly, Bactrocera tryoni

Insect Science, EarlyView.
Abstract Bactrocera tryoni, the Queensland fruit fly, is among the most damaging insect pests to the Australian horticultural industry as larvae infest ripening fruits or vegetables prior to harvest. Genetic biocontrol using Sterile Insect Technique (SIT) programs have been used to successfully suppress populations, via mass release of factory‐reared ...

CRISPR/Cas9‐mediated mutagenesis of the white‐eye gene in the tephritid pest Bactrocera zonata

Insect Science, EarlyView.
Abstract Bactrocera zonata is a highly invasive agricultural pest that causes extensive damage to fruit crops. The Sterile Insect Technique (SIT), a species‐specific and environmentally friendly pest control method, significantly benefits from the availability of Genetic Sexing Strains (GSSs) that enable efficient mass production of males for sterile ...

Development and evaluation of pupal color‐based genetic sexing strains in Anastrepha obliqua (Diptera: Tephritidae)

Insect Science, EarlyView.
Two spontaneous mutations in pupae of the West Indian fruit fly Anastrepha obliqua, named bp and sp, were isolated and studied. The bp mutation was selected, and using two types of Y‐autosoma l translocation inducers and an appropriate crossing scheme, two genetically sexed strains based on pupa l color were developed for the first time in this species,

DsiRNA‐mediated silencing of Ceratitis capitata transformer or transformer‐2 leads to masculinization of XX embryos and systemic gene silencing in ovaries

Insect Science, EarlyView.
We carried out functional studies using Dicer‐substrate small interfering RNAs (DsiRNAs), targeting the sex determination genes Cctransformer (Cctra) and Cctransformer‐2 (Cctra‐2) in the Mediterranean fruit fly (Ceratitis capitata). Microinjection of DsiRNAs into XX embryos (0‐1 h old) rapidly triggered the expression of male‐specific Cctra isoforms ...

Chromosome‐scale genome assembly of the South American fruit fly, Anastrepha fraterculus sp.1

Insect Science, EarlyView.
Anastrepha fraterculus sp. 1 is a major fruit fly pest in Argentina, currently controlled through chemical treatments and traps. This study aims to enhance the genomic understanding of this species to support the development of sterile insect technique as well as the use of innovative technologies.

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

Insect 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.
