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

Aphids-induced plant volatiles affect diel foraging behavior of a ladybird beetle Coccinella septempunctata [PDF]

open access: yesInsect Sci, 2020
The ladybird beetle Coccinella septempunctata (L.) is an important biocontrol agent of pests such as various aphid species. Despite being one of the most studied coccinellid species, many aspects of its foraging behavior are still not completely ...

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

open access: yesAgriculture, 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.

Effects of the Ecdysone Receptor on the Regulation of Reproduction in Coccinella septempunctata [PDF]

open access: yesInsects
The effects of the gene encoding the ecdysone receptor (EcR) on the reproduction of the ladybug Coccinella septempunctata was evaluated. EcR transcription was measured by quantitative real-time PCR in ladybug adults reared on artificial diets with and without 20-hydroxyecdysone (20E).

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)

Toxic effects of hexaflumuron on the development of Coccinella septempunctata [PDF]

open access: yesEnvironmental Science and Pollution Research, 2013
Studying the toxic risk of pesticide exposure to ladybird beetles is important from an agronomical and ecological perspective since larval and adult ladybirds are dominant predators of herbivorous pest insects (e.g., aphids) in various crops in China.
