Long term changes in abundance of Coccinella septempunctata (Coleoptera: Coccinellidae) in the Czech Republic

open access: yesEuropean Journal of Entomology, 2005
Since 1978, the abundance of Coccinella septempunctata L. has been recorded at a hibernation site in the western Czech Republic. Over the years, abundance varied by two orders of magnitude and a long-term trend for decrease in C. septempunctata abundance

Mitogenomic Characterization and Phylogenetic Expansion of Tribe Coccinellini (Coleoptera: Coccinellidae) [PDF]

open access: yesEcol Evol
This study presents the complete mitochondrial genomes of nine ladybird species from the tribe Coccinellini and compares them with 58 previously published mitogenomes. Phylogenetic analyses confirm the taxonomic placement of these species within Coccinellini.

Foraging in a complex environment - semiochemicals support searching behaviour of the seven spot ladybird

open access: yesEuropean Journal of Entomology, 2005
Knowledge of semiochemically-mediated behavioural mechanisms of the seven-spot ladybird, Coccinella septempunctata L., is limited but sufficient to encourage further studies in the behavioural ecology of this well known insect.

Antagonistic interactions between an invasive alien and a native coccinellid species may promote coexistence [PDF]

open access: yes, 2016
1. Despite the capacity of invasive alien species to alter ecosystems, the mechanisms underlying their impact remain only partly understood. Invasive alien predators, for example, can significantly disrupt recipient communities by consuming prey species ...

Pathogen avoidance by insect predators [PDF]

open access: yes, 2008
Insects can detect cues related to the risk of attack by their natural enemies. Pathogens are among the natural enemies of insects and entomopathogenic fungi attack a wide array of host species.

Long-term changes in communities of native coccinellids: population fluctuations and the effect of competition from an invasive non-native species [PDF]

open access: yes, 2016
1. We assessed the changes in abundance and community composition of native species of coccinellids (Coleoptera: Coccinellidae) on deciduous trees that occurred between 1970s and 2010s, in the Czech Republic. 2.

SYN‐A, a naturally derived synergist, restores pyrethroid efficacy against cabbage stem flea beetle but negatively impacts its parasitoid Microctonus brassicae

open access: yesPest Management Science, EarlyView.
SYN‐A, a naturally derived synergist, inhibited key metabolic pathways associated with pyrethroid insecticide resistance in cabbage stem flea beetle (CSFB) and its parasitoid Microctonus brassicae. SYN‐A restored pyrethroid efficacy against resistant CSFB allowing up to 80% reduction in application rates.

HvarAKR1B1‐mediated tolerance in Hippodamia variegata: Deciphering the metabolic adaptation and fitness costs under prolonged starvation

open access: yesPest Management Science, EarlyView.
Starvation stress significantly affected the growth and development of Hippodamia variegata. Combined transcriptome and metabolome analysis and RNA interference verification revealed that HvarAKR1B1 may be involved in the response of Hippodamia variegata to starvation stress.

Significant resource niche overlap between competing parasitoids does not prevent their successful co‐existence

open access: yesFunctional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Different species that exploit the same resources can sometimes co‐exist in the same habitat through resource sharing. For example, if resources are superabundant, then they can be easily partitioned interspecifically among different individuals. However, when resources
