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

open access: yesEnviron Sci Pollut Res Int, 2014
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.

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

open access: yesPLoS 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 developmental cost of leg regeneration, the developmental period and weight of leg-regenerated ...

The role of semiochemicals in the avoidance of the seven-spot ladybird, Coccinella septempunctata , by the aphid parasitoid, Aphidius ervi [PDF]

open access: yes, 2004
The role of semiochemicals in mediating intraguild interactions between the seven-spot ladybird, Coccinella septempunctata, and the aphid parasitoid, Aphidius ervi, was investigated. Female parasitoids avoided leaves visited by C.
