Consumption of Bt rice pollen containing Cry1C or Cry2A does not pose a risk to Propylea japonica (Thunberg) (Coleoptera: Coccinellidae). [PDF]

Sci Rep, 2015
As a pollen feeder, Propylea japonica would be directly exposed to Cry proteins in Bacillus thuringiensis (Bt)-transgenic rice fields. The effect of Cry1C- or Cry2A-containing transgenic rice pollen on the fitness of P. japonica was assessed using two dietary-exposure experiments in the laboratory.

Suitability of various prey types for the development of Propylea japonica (Coleoptera: Coccinellidae) [PDF]

European Journal of Entomology, 2007
The relative suitability of three prey organisms, Bemisia tabaci (Gennadius) eggs, B. tabaci nymphs, and Myzus persicae (Sulzer), to the ladybird Propylea japonica (Thunberg) was evaluated under laboratory conditions.

Expression of Cry1Ab/2Aj Protein in Genetically Engineered Maize Plants and Its Transfer in the Arthropod Food Web [PDF]

Plants, 2023
While transgenic Bacillus thuringiensis (Bt) maize provides pest resistance and a reduced application of chemical pesticides, a comprehensive environmental risk assessment is mandatory before its field release. This research determined the concentrations

Alternative splicing fine-tunes prey shift of Coccinellini lady beetles to non-target insect [PDF]

BMC Genomics
Background Coccinellini lady beetles have been applied as biological control agent of aphids, however, not all of these species are obligately aphidophagous. Thus, a comprehensive understanding of the molecular mechanisms behind predaceous specificity of

Influence of Host Species, Location, and Aphid Prey on Microbial Diversity and Community Dynamics of Aphidophagous Ladybird Beetles in Guangxi, China [PDF]

Ecol Evol
Analyses of the 16S rRNA amplicons of several ladybirds and their aphid prey from various locations in Guangxi, China reveal the plasticity of microbial abundance in aphidophagous ladybirds across different ladybird species and locations. Additionally, aphid symbionts are sporadically detected in the corresponding predator ladybirds, indicating their ...

TRPA1-kinase axis polarization: Nepetalactone drives pest repulsion and predator attraction via divergent PKC/CaMKII signaling [PDF]

Journal of Advanced Research
Introduction: Nepetalactone, an iridoid compound derived from Nepeta cataria, is a potent TRPA1 agonist known to repel hematophagous insects. However, its ecological roles and molecular mechanisms within agricultural ecosystems remain largely unexplored.

Development and reproduction of an aphidophagous coccinellid, Propylea japonica (Thunberg) (Coleoptera: Coccinellidae), reared on an alternative diet, Ephestia kuehniella Zeller (Lepidoptera: Pyralidae) eggs

Applied Entomology and Zoology, 2006
To establish a simple method for rearing Propylea japonica (Thunberg), we investigated its larval and pupal development and reproduction when offered Ephestia kuehniella Zeller eggs as an alternative diet. Larvae raised on E. kuehniella eggs matured as well as those raised on Acyrthosiphon pisum (Harris), and could be reared at high densities without ...

Changes in Metabolomics Profiles of <i>Propylea japonica</i> in Response to Acute Heat Stress. [PDF]

Int J Mol Sci
The ladybird beetle, Propylea japonica Thunberg (Coleoptera: Coccinellidae), is a widely distributed natural predator that is crucial in controlling various agricultural pests in China. Despite frequent references to its remarkable thermotolerance, the molecular mechanisms underlying its thermotolerance remain poorly understood.
