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

Ultrastructural and Functional Organization of Maxillary Palps in Ladybird Species (Coleoptera: Coccinellidae) With Different Feeding Preferences. [PDF]

open access: yesMicrosc Res Tech
This research described the ultrastructural organization of Coccinellidae maxillary palps. The apical sensory area housed the largest number of sensilla. The sensilla belonged to three types: uniporous, multiporous, and campaniform sensilla. Large number of sensilla and sensory neurons provide evidence that maxillary palps act as primary sensory organ ...

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 ...
