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

open access: yesInsect 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 ...

LsFAMeT and LsJHAMT coordinate JH biosynthesis to regulate fecundity in Laodelphax striatellus

open access: yesInsect Science, EarlyView.
The small brown planthopper (SBPH), Laodelphax striatellus, can trigger large‐scale outbreaks when encountering suitable habitats during migration due to their strong reproductive ability. This study investigated the role of juvenile hormone (JH) in regulating SBPH reproduction.

Similar songs, but different mate localization strategies of the three species of Phaneroptera occurring in Western Europe (Orthoptera: Phaneropteridae)

open access: yesEuropean Journal of Entomology, 2021
In bush-crickets, males produce a calling song to announce their presence to females. Females ready to mate respond either by a phonotactic approach or signal their presence acoustically by establishing a kind of duet.

TcALS knockdown accelerates metamorphosis via insulin signaling in Tribolium castaneum

open access: yesInsect Science, EarlyView.
RNAi silencing of TcALS accelerates larva‐to‐pupa metamorphosis in Tribolium castaneum. Abstract Insect metamorphosis is an evolutionary adaptation precisely regulated by nutritional and hormonal cues. The red flour beetle Tribolium castaneum, a major stored‐product pest, serves as an excellent model for studying this process.

The value of regeneration for insect fauna associated with leaf litter in the Brazilian savanna: A comparative study of biomass and trophic structure

open access: yesAnnals of Applied Biology, EarlyView.
This study demonstrates the ecological value of natural regeneration in the Brazilian Cerrado by analysing the biomass, richness and trophic structure of leaf litter insects across pasture (P), regenerating (R) and native (N) areas. We found that R areas supported insect communities more similar to N habitats than to Ps, with higher richness, greater ...

A systematic review on research trends and commercialised entomopathogenic nematodes: A global perspective

open access: yesAgricultural and Forest Entomology, EarlyView.
Out of 136 identified EPNs, only 18 (8 Steinernema and 6 Heterorhabditis) are commercialised globally, highlighting a major gap between discovery and application. High production costs and inconsistent field efficacy are the leading obstacles to the widespread commercialisation of EPN‐based biocontrol products.

Harnessing social media data to track species range shifts

open access: yesConservation Biology, EarlyView.
Abstract Biodiversity monitoring programs and citizen science data remain heavily biased toward the Global North. Especially in megadiverse countries with limited biodiversity records, incorporating social media data can help address existing data gaps.

Changes in the numbers of chromosomes and sex determination system in bushcrickets of the genus Odontura (Orthoptera: Tettigoniidae: Phaneropterinae)

open access: yesEuropean Journal of Entomology, 2011
Chromosomes of the males of five species of Odontura, belonging to the subgenera Odontura and Odonturella, were analyzed. Intensive evolution of the karyotype was recorded, both in terms of changes in the numbers of chromosomes (from 2n = 31 to 27) and ...
