Consumption of Bt Maize Pollen Containing Cry1Ie Does Not Negatively Affect Propylea japonica (Thunberg) (Coleoptera: Coccinellidae) [PDF]

Toxins, 2017
Propylea japonica (Thunberg) (Coleoptera: Coccinellidae) are prevalent predators and pollen feeders in East Asian maize fields. They are therefore indirectly (via prey) and directly (via pollen) exposed to Cry proteins within Bt-transgenic maize fields ...

Use of a pollen-based diet to expose the ladybird beetle Propylea japonica to insecticidal proteins. [PDF]

PLoS ONE, 2014
A rape seed pollen-based diet was developed and found to be suitable for use in a dietary exposure assay for Propylea japonica. Using the diet, we established and validated a dietary exposure assay by using the protease inhibitor E-64 as positive control.

Discovery and identification of a male-killing agent in the Japanese ladybird Propylea japonica (Coleoptera: Coccinellidae) [PDF]

BMC Evolutionary Biology, 2010
Background Endosymbionts that manipulate the reproduction of their hosts have been reported widely in invertebrates. One such group of endosymbionts is the male-killers.

Bt, Not a Threat to Propylea japonica [PDF]

Frontiers in Physiology, 2020
Given the ever-increasing commercial planting of transgenic plants across the world, an evaluation of their impacts on non-target organisms is as an important part of the risk assessment process.

Gut Microbe‐Driven Resistance Mechanisms in Propylea Japonica: Insights from Horizontal Gene Transfer and Oxidative Phosphorylation [PDF]

Advanced Science
Insect–microbial symbiont relationships are widespread in nature and often involve lateral gene transfer. Although the evolutionary processes that allow insects to adapt to complex environments remain largely unknown, it is clear that symbiotic ...

Comparative genomic analysis reveals the genetic basis of the environmental adaptability of Propylea japonica [PDF]

BMC Genomics
Background Propylea japonica is a widely distributed natural enemy insect that preys on aphids, whiteflies, and other pests. Owing to its exceptional environmental adaptability, this species serves as an effective biological control agent.

Unintended changes in transgenic maize cause no nontarget effects

Plants, People, Planet, 2022
Societal Impact Statement Genetic engineering is used to introduce new genes into plants to obtain crops with novel traits. However, the unintended effects of genetically engineered (GE) crops on nontarget organisms—such as beneficial insects—are a topic

Characterization of the complete mitochondrial genome and phylogenetic analysis of Coelophora saucia (Mulsant, 1850) (Coleoptera: Coccinellidae) [PDF]

Mitochondrial DNA. Part B. Resources
Coelophora saucia is an important natural enemy insect in agricultural production. We determined the complete mitochondrial genome of the C. saucia by high-throughput sequencing, and the mitogenome was 18,068 bp in length, with a GC content of 20.9 ...
