Mitochondrial genome of Lemnia saucia Mulsant (Coleoptera: Coccinellidae) and phylogenetic analysis

open access: yesMitochondrial DNA. Part B. Resources, 2019
We sequenced and annotated the nearly complete mitochondrial genome (mitogenome) of Lemnia saucia (Coleoptera: Coccinellidae). This mitogenome was 14,106 bp long and encoded 13 protein-coding genes (PCGs), 19 transfer RNA genes, and two ribosomal RNA ...

Kin recognition and avoidance of kin cannibalism by the larvae of co-occurring ladybirds: a laboratory study

open access: yesEuropean Journal of Entomology, 2005
The role of relatedness and diet in kin recognition was investigated in the aphidophagous ladybirds Propylea dissecta and Coccinella transversalis. Third instar larvae of both species exhibited kin recognition, as they were reluctant to consume related ...

Functional responses of immature stages of Propylea quatuordecimpunctata (Coleoptera: Coccinellidae) to Aphis fabae (Hemiptera: Aphididae)

open access: yesEuropean Journal of Entomology, 2011
Functional responses of immature stages of Propylea quatuordecimpunctata (L.) to varying densities of Aphis fabae Scopoli reared on Vicia faba L. were evaluated under laboratory conditions. All larval stages of the predator were starved for 12 h prior to

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

open access: yesPLoS 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.

Ageing trajectory and longevity trade-off in an aphidophagous ladybird, Propylea dissecta (Coleoptera: Coccinellidae)

open access: yesEuropean Journal of Entomology, 2006
The ageing trajectory (trend in ageing) and reproduction-longevity trade-off in both sexes of the ladybird Propylea dissecta were studied. The ageing trajectories of both sexes were investigated in terms of reproductive performance, using initial ...

Optimal experimental design for predator–prey functional response experiments [PDF]

open access: yes, 2018
Functional response models are important in understanding predator–prey interactions. The development of functional response methodology has progressed from mechanistic models to more statistically motivated models that can account for variance and the ...
