Response of chrysopids (Neuroptera) to larval tracks of aphidophagous coccinellids (Coleoptera) [PDF]

open access: yesEuropean Journal of Entomology, 2001
Choice tests showed that tracks left by coccinellid larvae have generally little effect on oviposition site selection by chrysopid females. Fresh tracks of first instar larvae of the coccinellid species Coccinella septempunctata, Cycloneda limbifer, Leis

Water Budget in Larvae of Semiadalia undecimnotata Schn. Studied with Tritiated Water

open access: yesZeitschrift Fur Naturforschung - Section C Journal of Biosciences, 1980
Abstract The rates of water vapor entry, body water clearance and the net loss of water in larvae of Semi­ adalia undecimnotata (3rd and 4th stage) of different weights were determined from observed changes in the mass of body water and its tritium content for each of several relative humidities (RH) in ambient air.

Sexual activity in Coccinellidae (Coleoptera): a review

open access: yesEuropean Journal of Entomology, 2000
Although there are few studies of the sexual life of coccinellids these phenomena have attracted the interest of isolated groups of coccinellidologists. Probably the most important finding is that at least some coccinellid species (Adalia bipunctata and ...

Efficiency of the aphidophagous coccinellid Semiadalia undecimnotata Schn. in the glasshouse

open access: yes, 1984
Les larves de la coccinelle Semiadalia undecimnotata sont utilisées au dernier stade sous forme de traitements inondatifs contre les pucerons des aubergines en serre. Le nombre d’individus lâchés sur chaque plante est calculé en fonction des aptitudes trophiques du stade utilisé et de la biomasse aphidienne totale à exploiter. Dans la majorité des cas,
