Presence of cardenolides and ursolic acid from oleander leaves in larvae and frass of Daphnis nerii

Phytochemistry, 1996
Cardenolide glycosides from larvae of the sphingid moth Daphnis nerii reared on oleander leaves, and those from their frass, were examined by HPLC and then isolated preparatively. Most of the cardenolide triosides in the leaves were detected as their corresponding monosides in the larval and frass extracts.

Feeding and nutritional influence on growth and reproduction of Daphnis nerii (Linn.) (Lepidoptera: Sphingidae)

Journal of Insect Physiology, 1992
Abstract The impact of age-correlated biochemical changes in Nerium oleander leaves on food consumption and utilization efficiency of Daphnis nerii (Linn.) is provided. The relative preference and maximal utilization of young leaves when compared to mature and senescent leaves are attributed to the changes in the chemical profiles such as protein ...

Target-site sensitivity in a specialized herbivore towards major toxic compounds of its host plant: the Na+K+-ATPase of the oleander hawk moth (Daphnis nerii) is highly susceptible to cardenolides

Chemoecology, 2009
The caterpillars of the oleander hawk moth, Daphnis nerii (Linnaeus, 1758) (Lepidoptera: Sphingidae) feed primarily on oleander (Nerium oleander). This plant is rich in cardenolides, which specifically inhibit the Na+K+-ATPase. Since some insects feeding on cardenolide plants possess cardenolide-resistant Na+K+-ATPases, we tested whether D.

EFFECT OF HOST PLANT SECONDARY CHEMICALS ON FOOD UTILIZATION OF DAPHNIS NERII (LINN.) (LEPIDOPTERA : SPHINGIDAE)

open access: yes, 1996
Influence of age correlated host leaf secondary chemicals of Nerium oleander on food utilization of Daphnis nerii (Linn.) is provided. Amount of food consumed as well as the efficiency ofingested (ECI) and digested (ECD) food were decreased onsenescent leaves fed insects than other leaf stages.

The motor apparatus of head movements in the Oleander hawkmoth ( Daphnis nerii , Lepidoptera)

Journal of Comparative Neurology, 2023
Abstract Head movements of insects play a vital role in diverse locomotory behaviors including flying and walking. Because insect eyes move minimally within their sockets, their head movements are essential to reduce visual blur and maintain a stable gaze. As in most vertebrates, gaze stabilization behavior in insects

Morphological Characteristics and Developmental Stages of Daphnis nerii (Oleander Hawk-Moth)

International Journal of Applied and Advanced Biology (IJAAB), 2023
Abstract The life cycle of Daphnis nerii, commonly known as the Oleander Hawk-Moth, was investigated through laboratory rearing in 2022. The study focused on observing the morphology and duration of different life stages, including the egg, larva, pupa, and adult. The life cycle of D. nerii consisted of five instars.
