Clap-and-Fling Mechanism of Climbing-Flight Coccinella Septempunctata [PDF]

open access: goldBiomimetics
Previous studies on the clap–fling mechanism have predominantly focused on the initial downward and forward phases of flight in miniature insects, either during hovering or forward flight.

Developmental cost of leg-regenerated Coccinella septempunctata (Coleoptera: Coccinellidae). [PDF]

open access: goldPLoS ONE, 2019
As larval cannibalism is common under intensive rearing conditions, leg regeneration can help ladybugs adapt to the competitive environment, but whether the leg regeneration leads to side effects on development remains unclear. To analyze the potentially

Kinematic and Aerodynamic Analysis of a Coccinella septempunctata Performing Banked Turns in Climbing Flight [PDF]

open access: yesBiomimetics
Many Coccinella septempunctata flights, with their precise positioning capabilities, have provided rich inspiration for designing insect-styled micro air vehicles. However, researchers have not widely studied their flight ability. In particular, research

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

open access: goldEuropean 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

The Toxicity Response of Coccinella septempunctata L. (Coleoptera: Coccinellidae) after Exposure to Sublethal Concentrations of Acetamiprid [PDF]

open access: goldAgriculture, 2022
Coccinella septempunctata is a nontarget beneficial arthropod and an important aphid predator in agricultural crops. In this study, the toxic effects of the neonicotinoid acetamiprid on C.

Toxicity and Lethal Effect of Greenhouse Insecticides on Coccinella septempunctata (Coleoptera: Coccinellidae) as Biological Control Agent of Myzus persicae (Hemiptera: Aphididae) [PDF]

open access: yesToxics, 2023
Deltamethrin and imidacloprid are commonly used insecticides for controlling sub-sucking insects in greenhouses. However, their application may cause sublethal effects on the aphid coccinellid predator Coccinella septempunctata (Coleoptera: Coccinellidae)

Toxicity and Sublethal Effects of Diamide Insecticides on Key Non-Target Natural Predators, the Larvae of Coccinella septempunctata L. (Coleoptera: Coccinellidae) [PDF]

open access: yesToxics, 2023
Coccinella septempunctata (ladybird) is an extremely important natural predator that feeds on aphids. An assessment of the toxicity of pesticides on environmental organisms is an essential component of Integrated Pest Management (IPM) strategies.
