Fitness of two phenotypes of Harmonia axyridis (Coleoptera: Coccinellidae)
TLDR
It is suggested that a genotype that confers a specific pattern of elytra could also confer other specific autecological attributes, such as longevity and reproductive capacity, that could affect its fitness. Expand
The harlequin ladybird, Harmonia axyridis: global perspectives on invasion history and ecology
TLDR
An overview of the invasion history and ecology of H. axyridis globally with consideration of future research perspectives is provided. Expand
Intraguild predation between the aphidophagous ladybird beetles Harmonia axyridis and Coccinella undecimpunctata (Coleoptera: Coccinellidae): The role of intra and extraguild prey densities
TLDR
The results and those of other authors suggest that H. axyridis has the potential to be an IGpredator, mainly of the most vulnerable stages of IGprey, and may negatively affect the survival of C. undecimpunctata when these two species exploit the same resources. Expand
Effect of Temperature and Intraspecific Allometry on Predation by Two Phenotypes of Harmonia axyridis Pallas (Coleoptera: Coccinellidae)
TLDR
Temperature is a limiting factor to larval and adult relative consumption rate and predation activity of fourth instars and adults of aulica and nigra phenotypes were compared, and body size and shape could explain the differences observed. Expand
Intraguild predation between the aphidophagous ladybird beetles Harmonia axyridis and Coccinella undecimpunctata (Coleoptera: Coccinellidae): the role of body weight
The magnitude, direction and symmetry of intraguild predation (IGP) between the developmental stages of the aphido- phagous Harmonia axyridis Pallas and Coccinella undecimpunctata L. wereExpand
Dietary self‐selection behaviour by the adults of the aphidophagous ladybeetle Harmonia axyridis (Coleoptera: Coccinellidae)
TLDR
The results suggest that H. axyridis present self-selection behaviour because they agree with the basic criteria of Waldbauer and Friedman's self- selection, i.e. the animal's choice of food or nutrients is non-random, and the coccinellid benefits from self-selecting. Expand
Voracity of Coccinella undecimpunctata: effects of insecticides when foraging in a prey/plant system
TLDR
Results suggest that C. undecimpunctata does not detect the insecticide on the aphids and indicate that the increase in voracity may be due to a decrease in the mobility of insecticide-treated aphids, since their capture should be easier than highly mobile non-treated prey. Expand
Suitability of Aphis fabae, Myzus persicae (Homoptera: Aphididae) and Aleyrodes proletella (Homoptera: Aleyrodidae) as prey for Coccinella undecimpunctata (Coleoptera: Coccinellidae)
The suitability of Aphis fabae Scopoli, Myzus persicae Sulzer and Aleyrodes proletella L. as food sources for Coccinella undecimpunctata L. was evaluated by studying the impact of prey consumption onExpand
Effects of pirimicarb, buprofezin and pymetrozine on survival, development and reproduction of Coccinella undecimpunctata (Coleoptera: Coccinellidae)
TLDR
In general, pirimicarb and pymetrozine had no adverse effects on immature or adult stages of C. undecimpunctata, and hence are suitable for IPM of sucking pests. Expand
Invasions by ladybugs, ladybirds, and other predatory beetles
TLDR
This topic is addressed by focusing on invasive alien ladybird beetles (Coccinellidae) by making clear the potential of invasive alien predatory Coleoptera to disrupt invaded natural and agricultural ecosystems. Expand
