Carotenoids of the ladybird beetle, Coccinella septempunctata

Insect Biochemistry, 1977
Abstract The carotenoids of the seven-spot ladybird beetle ( Coccinella septempunctata ) consist largely of hydrocarbons. Phytoene, phytofluene, ζ-carotene, and its unsymmetrical isomer 7,8,11,12-tetrahydrolycopene, neurosporene, lycopene, 3,4-didehydrolycopene, 7′,8′,11′,12′-tetrahydro-γ-carotene, β-zeacarotene, γ-carotene, torulene, β-carotene, 7 ...

Vitellogenin synthesis in the lady beetle Coccinella septempunctata

Insect Biochemistry, 1984
Abstract To elucidate the hormonal mechanisms which regulate reproduction in a beneficial insect, we have begun to investigate the process of vitellogenesis in Coccinella septempunctata, the seven-spotted lady beetle. Vitellin (Vn) constitutes 60–70% of the total protein in C.

Pigmentation of the ladybird beetle Coccinella septempunctata by carotenoids not of plant origin

Nature, 1977
MANY insects contain carotenoid pigments1, and some notable examples are found in the Coleoptera, where carotenoids are responsible for the yellow colour of the yellow and black striped wing cases of the Colorado beetle, Leptinotarsa decemlineata, and the orange-red colour of the ladybird beetles, Coccinella spp.

Interactions of Coccinella novemnotata (Coleoptera: Coccinellidae) and Coccinella septempunctata (Coleoptera: Coccinellidae) While Foraging for Aphids

Environmental Entomology, 2018
The importation and establishment of Coccinella septempunctata L. (Coleoptera: Coccinellidae) in North America purportedly caused the displacement and local extirpation of the native ninespotted lady beetle, Coccinella novemnotata Herbst (Coleoptera: Coccinellidae), across most of its former range, and several reports have shown that C.

Response of the Ladybird Parasitoid Dinocampus coccinellae to Toxic Alkaloids from the Seven-spot Ladybird, Coccinella septempunctata

Journal of Chemical Ecology, 2001
Electrophysiological and behavioral responses of the ladybird parasitoid Dinocampus coccinellae to volatiles from the seven-spot ladybird, Coccinella septempunctata, were investigated to identify semiochemicals involved in host location. Coupled gas chromatography-electroantennography (GC-EAG) with D.

SEQUENTIAL SAMPLING OF ADULT COCCINELLA SEPTEMPUNCTATA L. IN WHEAT FIELDS

The Canadian Entomologist, 1988
AbstractA sequential sampling program was designed for Coccinella septempunctata L. adults in wheat fields, based on a rapid visual counting method. This program takes into account the spatial heterogeneity of coccinellids and the efficiency of the counting method.
