The transformer gene controls sexual development in Drosophila suzukii

Insect Science, Volume 33, Issue 2, Page 547-565, April 2026.
The transformer gene plays a key role in the genetic pathway for sexual development in Drosophila suzukii Abstract The genetic network of sex determination in the model organism Drosophila melanogaster was investigated in great detail. Such knowledge not only advances our understanding of the evolution and regulation of sexual dimorphism in insects ...

Genetic engineering for SIT application: a fruit fly‐focused review

Insect Science, Volume 33, Issue 2, Page 703-723, April 2026.
Abstract Sterile insect technique (SIT) has become a key component of efficient pest control. Fruit fly pests from the Drosophilidae and Tephritidae families pose a substantial and overwhelmingly increasing threat to the agricultural industry, aggravated by climate change and globalization among other contributors.

Drosophila Hox and sex-determination genes control segment elimination through EGFR and extramacrochetae activity.

PLoS Genetics, 2012
The formation or suppression of particular structures is a major change occurring in development and evolution. One example of such change is the absence of the seventh abdominal segment (A7) in Drosophila males.

Phylogenetic analysis and embryonic expression of panarthropod Dmrt genes

Frontiers in Zoology, 2019
Background One set of the developmentally important Doublesex and Male-abnormal-3 Related Transcription factors (Dmrt) is subject of intense research, because of their role in sex-determination and sexual differentiation.

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

Insect Science, Volume 33, Issue 2, Page 640-664, April 2026.
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.

Molecular evolution of Drosophila Sex-lethal and related sex determining genes

BMC Evolutionary Biology, 2012
Background Sex determining mechanisms are evolutionarily labile and related species often use different primary signals and gene regulatory networks. This is well illustrated by the sex determining cascade of Drosophila fruitflies, which have recruited ...

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

Insect Science, Volume 33, Issue 2, Page 724-743, April 2026.
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.

Characteristic and Functional Study of Intersex, a Gene Related to Female Fertility in Bemisia tabaci

Frontiers in Physiology, 2020
The intersex (ix) gene acts in concert with doublesex (dsx) at the end of the sex determination hierarchy to control somatic sexual differentiation in Drosophila melanogaster.

Synthetic biology approaches to generate temperature‐sensitive alleles for the Sterile Insect Technique

Insect Science, Volume 33, Issue 2, Page 517-532, April 2026.
Abstract The Sterile Insect Technique (SIT) is an environmentally friendly, sustainable pest control approach, which uses large‐scale releases of sterile insects to suppress or eradicate target populations through infertile matings. The efficiency of SIT is enhanced by male‐only releases requiring genetic sexing strains (GSSs) that are classically ...

CRISPR/Cas9‐based white pupae mutant lines in Bactrocera spp. for sterile insect technique applications

Insect Science, Volume 33, Issue 2, Page 463-475, April 2026.
Bactrocera fruit flies are significant horticultural pests that cause major economic losses. A “neoclassical approach” incorporating genome editing via CRISPR/Cas9 to develop genetic sexing strains (GSS) could render the sterile insect technique (SIT) against these pests more efficient and cost‐effective.
