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

open access: yesInsect 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.

Drosophila Zic family member odd-paired is needed for adult post-ecdysis maturation [PDF]

open access: yesOpen Biology, 2019
Specific neuropeptides regulate in arthropods the shedding of the old cuticle (ecdysis) followed by maturation of the new cuticle. In Drosophila melanogaster, the last ecdysis occurs at eclosion from the pupal case, with a post-eclosion behavioural ...

Ecological and social factors lead to variation in parental care between sexes in a burying beetle

open access: yesInsect Science, EarlyView.
We experimentally investigated the effects of ecological (resource availability and interspecific competition) and social factors (intraspecific competition) on parental care and reproductive success in the burying beetle Nicrophorus vespilloides. Our results showed that males and females adjust their parental care based on resource availability and ...

Silencing of juvenile hormone‐related genes through RNA interference leads to molt failure and high mortality in the spongy moth

open access: yesInsect Science, EarlyView.
The feasibility of using RNA interference to control the globally important quarantine pest, the spongy moth. Targeting genes related to JHs play an important role in the growth and development of insects. First, the open reading frames (ORFs) of Ldjhamt and Ldjheh were identified and characterized, and the target genes were cloned and double‐stranded ...
