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 ...

Potential of alternative control of leaf‐cutting ants using essential oils: A systematic review

open access: yesAgricultural and Forest Entomology, EarlyView.
Abstract Leaf‐cutting ants (LCAs) are abundant and cause considerable damage to agricultural and forest crops in the Neotropical region and are commonly controlled using sulfluramid‐based ant baits. However, this active ingredient is a precursor of perfluorooctane sulfonic acid (PFOS), a persistent, human‐made pollutant that poses serious environmental
