Chemical studies of rectal gland secretions of some species ofBactrocera dorsalis complex of fruit flies (diptera: Tephritidae)
Male-produced rectal gland secretions of a number of species now considered to be members of theBactrocera dorsalis complex of fruit flies have been examined by combined gas chromatography-mass
Pyrrolizidine alkaloids in Crotalaria taxa from northern Australia: risk to grazing livestock.
Taxa with high levels of hepatotoxic alkaloids, abundance, and biomass pose the greatest risk to livestock health, particularly C. novae-hollandiae, C. retusa, and C. crispata .
Isoquinoline alkaloids and keto-fatty acids of Argemone ochroleuca and A. mexicana (mexican poppy) seed.II. Concentrations tolerated by pigs
A safe tolerance of 0.2% in the diet of grower pigs, and up to 1% for finisher pigs, is suggested, based on alkaloid contents of A. ochroleuca and A. mexicana, which were fed to pigs in several experiments to determine tolerable concentrations in pig diets.
Residue potential of norsesquiterpene glycosides in tissues of cattle fed Austral bracken (Pteridium esculentum).
This detection of residual glycosides in tissues of cattle feeding on Austral bracken raises health concerns for consumers and warrants further investigation.
Norsesquiterpene glycosides in bracken ferns (Pteridium esculentum and Pteridium aquilinum subsp. wightianum) from Eastern Australia: reassessed poisoning risk to animals.
The presence of this additional reactive glycoside in Australian P. esculentum implies greater toxicity for consuming animals than previously estimated from ptaquiloside content alone.
Chemistry of Leichhardt's Grasshopper, Petasida ephippigera, and its Host Plants, Pityrodia jamesii, P. ternifolia, and P. pungens
Investigation of the strikingly aposematic Leichhardt's grasshopper revealed a number of host-plant-derived components and no evidence for previously suspected "alkaloidal" toxins was found in either the insect or host plant.
