Dynamic transcriptome analysis and Methoprene-tolerant gene knockdown reveal that juvenile hormone regulates oogenesis and vitellogenin synthesis in Propylea Japonica

open access: yesGenomics, 2021
Propylea japonica has been regarded as one of the most remarkable natural enemies against aphid in China. However, the mechanism of juvenile hormone (JH) regulation of reproduction in P. japonica is still unclear. In this study, we investigated the JH titers of P. japonica and the development of the ovaries.

Bacillus thuringiensis protein Vip3Aa does not harm the predator Propylea japonica: A toxicological, histopathological, biochemical and molecular analysis

open access: yesEcotoxicology and Environmental Safety, 2020
The ladybeetle Propylea japonica is a widely distributed natural enemy in many agricultural systems. P. japonica is often used as a test organism for safety assessments of transgenic Bacillus thuringiensis crops. Plant varieties expressing the Vip3Aa insecticidal protein are not currently commercially available in China.

Exploring the Influence of Insect Honeydew on Plant Physiology and Health: Bridging the Gap in Current Understanding

open access: yesPhysiologia Plantarum, Volume 177, Issue 6, November/December 2025.
ABSTRACT Honeydew, a sugary excretion from sap‐feeding insects, significantly influences plant‐insect interactions. While extensive research has examined honeydew's composition, regulation, and role in insect‐plant relationships, its direct effects on plant physiology and health remain understudied.

Bt rice in China — focusing the nontarget risk assessment

open access: yesPlant Biotechnology Journal, Volume 15, Issue 10, Page 1340-1345, October 2017., 2017
Summary Bt rice can control yield losses caused by lepidopteran pests but may also harm nontarget species and reduce important ecosystem services. A comprehensive data set on herbivores, natural enemies, and their interactions in Chinese rice fields was compiled.

Biological Flora of Britain and Ireland: Cytisus scoparius*

open access: yesJournal of Ecology, Volume 113, Issue 7, Page 1877-1933, July 2025.
Broom is an attractive and common native plant across Britain, Ireland and most of Europe, and yet it is considered a harmful and invasive weed around the rest of the world. This is aided by broom thriving on poor dry soils, helped by using green stems for photosynthesis and having root nodules to fix nitrogen.
