Parental age at mating affects reproductive attributes of the aphidophagous ladybird beetle, Coelophora saucia (Coleoptera: Coccinellidae)

European Journal of Entomology, 2010
Ageing and its affect on life attributes have not been widely explored in ladybirds. The present study investigates the influence of female and male age at mating on the reproductive attributes of the ladybird beetle, Coelophora saucia (Mulsant).

Effect of Dietary Protein and Carbohydrates on Survival and Growth in Larvae of the Henosepilachna vigintioctopunctata (F.) (Coleoptera: Coccinellidae)

Journal of Insect Science, 2018
The ratio of protein and carbohydrate in an insect’s nutritional regime can significantly influence its survival, growth, and fecundity. The effects of 11 different artificial diets containing protein (p): carbohydrate (c) ratios were determined in ...

The biogeography of Coccinellidae in the Pacific area [PDF]

GeoJournal, 1983
This paper is an attempt to sum up our knowledge of the coccinellid fauna in the Pacific area. About 560 species have been recorded from the area, in which Australia has been included because it is essential for a proper understanding of the Melanesian insular faunas. Major points emerging from this.

Body size and the temporal sequence in the reproductive activity of two species of aphidophagous coccinellids exploiting the same resource

European Journal of Entomology, 2008
The hypothesis that small species of aphidophagous coccinellids need lower aphid population densities for reproduction than large species (Dixon, 2007) was tested in the field.

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

European 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.
