The Application of Carbon Dots in Crops for Sustainable Agriculture

open access: yesChemistryEurope, EarlyView.
Carbon dots serve as versatile nanoagents across the crop life cycle. They promote plant growth and photosynthesis, enhance resilience to biotic and abiotic stresses, aid in postharvest preservation, and enable sensitive detection of contaminants.

Role of mitochondrial complex I genes in host plant expansion of Bactrocera tau (Tephritidae: Diptera) by CRISPR/Cas9 system

open access: yesInsect Science, EarlyView.
The role of 3 mitochondrial complex I gene in host expansion of Bactrocera tau was verified by CRISPR/Cas9 gene editing system. A stable homogenous strain (Btndufa7‐/‐) of B.tau was established after silencing Ndufa7. The reduced size of larvae and pupae of Ndufa7 knockout strain was first found.Then different levels of fitness and relative expression ...

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

open access: yesInsect 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.
