Temperature-Dependent Ovarian Development in Coccinella septempunctata (Coleoptera: Coccinellidae)
Annals of the Entomological Society of America, 1995A linear relationship was observed between ovarian developmental rate in Coccinella septempunctata L. and five constant temperatures (14-30°C). The estimated lower temperature threshold for follicle development was 13°C. Development of follicles to maturity (egg chorionation) required 833 degree-hours (° H > 13°C).

SEQUENTIAL SAMPLING OF ADULT COCCINELLA SEPTEMPUNCTATA L. IN WHEAT FIELDS
The Canadian Entomologist, 1988AbstractA 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.

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.

Biological Control of Aphid by using Beetle (Coccinella septempunctata)
World Journal of Biology Pharmacy and Health SciencesDevelopment and reproductive potential of the Coccinella septempunctata L. CSL was conducted under normal conditions to determine its fecundity and longevity on natural diet. Tests were made on normal temperature rearing materials and all development stages were carefully recorded. Diet quality is related to egg production, so CSL fertility is affected

Phototactic Behavior ofCoccinella septempunctataL. (Coleoptera: Coccinellidae)
The Coleopterists Bulletin, 2013We studied the behavioral response of the seven-spotted ladybird beetle, Coccinella septempunctata L., (Coleoptera, Coccinellinae) to various light wavelengths and intensities. Significant differences in the phototactic responses of beetles to 15 wavelengths of monochromatic light and white light were found.
