Alkaloid tolerance in Manduca sexta and phylogenetically related sphingids (Lepidoptera: Sphingidae)CHEMOECOLOGY - Tập 12 - Trang 29-46 - 2002
Michael Wink, Vera Theile
Nicotine tolerance is well known for Manduca sexta. It also occurs in several other sphingids of the subfamilies Macroglossinae and Sphinginae. Only members of the subfamily Smerinthinae appear to be more susceptible to nicotine intoxication. Phylogenetic trees have been reconstructed from mitochondrial 16S rDNA and nuclear DNA to map nicotine tolerance.¶The nicotine binding site of both α-subunit...... hiện toàn bộ

Males of Bombus terrestris (L.) adopt a patrolling behaviour during their nuptial parade using cephalic labial gland (CLG) secretions containing sexual pheromones to attract conspecific virgin queens. The changes in chemical composition of their CLG secretions with age are quite well known. In this study, we investigate the evolution of CLG secretions with age in greater detail and compare behavio...... hiện toàn bộ
Allelochemicals from Thapsia garganica leaves for Lolium perenne L. control: the magic of mixturesCHEMOECOLOGY - Tập 32 - Trang 81-87 - 2022

Luteolin 7-O-glucoside (1), 10β-acetoxy-8α-butyryloxy-11α-hydroxy-2β-((2-methylbutanoyl)oxy)-1βH,6αH,7αH,11βH-guaian-3-en-12,6-olide (2) and thapsigargin (3) herbicidal activities’ were evaluated in comparison with their binary and tertiary mixtures, against Lolium perenne. These allelochemicals were isolated from Thapsia garganica leaves methanolic extract. Experiments were carried out by irrigat...... hiện toàn bộ
