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,

Full‐length transcriptome profiling of true bug mitochondrial genomes reveals the unique transcriptional regulation during insect evolution

Insect Science, EarlyView.
The mitogenome was transcribed into complete primary polycistrons on both strands. The heteropteran mitochondrial transcription termination factor (HmTTF) functions as a bidirectional attenuator rather than a terminator, and co‐evolution of HmTTF and the binding sites was observed.

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.

Effect of male age at the time of irradiation on the sexual performance of sterile Ceratitis capitata males: insights from remating female offspring

Insect Science, EarlyView.
Abstract The Sterile Insect Technique (SIT) is an effective strategy for controlling insect pests, such as the Mediterranean fruit fly (Ceratitis capitata, Wiedemann). The effectiveness of the SIT depends on the ability of the sterile males to mate and their capacity to induce sterility in wild females.

Iflaviruses in arthropods: when small is mighty

Insect 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.

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.
