TLDR
The moth Utetheisa ornatrix (Lepidoptera: Arctiidae) is protected against predation by pyrrolizidine alkaloids that it sequesters as a larva from its foodplants, and females reinforce after copulation the choice mechanism they already exercise during courtship.
Defensive Secretions of Millipeds
The millipeds, comprising the arthropodan class Diplopoda, are a relatively uniform and unspectacular lot. Generally slow and sluggish despite their many legs, they are for the most part furtive
Firefly "femmes fatales" acquire defensive steroids (lucibufagins) from their firefly prey.
TLDR
It is found that by feeding on Photinus males, Photuris females gain more than nutrients, and acquire defensive steroidal pyrones called lucibufagins, which are contained in Photinus but which photuris fireflies are unable to produce on their own.
Grass roots chemistry: meta-Tyrosine, an herbicidal nonprotein amino acid
TLDR
It is shown that m-tyrosine exposure results in growth inhibition for a wide range of plant species and proposed that the release of this nonprotein amino acid interferes with root development of competing plants and could lead to the development of biorational approaches to weed control.
Biparental defensive endowment of eggs with acquired plant alkaloid in the moth Utetheisa ornatrix.
TLDR
Field and laboratory tests showed that the alkaloids of Utetheisa ornatrix protect eggs from predators, and a previously identified pheromone, derived by the male from the alkAloid and emitted during precopulatory behavior, may announce the male alkaloidal worth to the female.
Attractive and defensive functions of the ultraviolet pigments of a flower (Hypericum calycinum)
TLDR
It is found the DIPs to be present in high concentration in the anthers and ovarian wall of the flower, suggesting that the compounds also serve in defense.
Defense of Phalangid: Liquid Repellent Administered by Leg Dabbing
TLDR
The phalangid Vonones sayi has a pair of exocrine defensive glands that secrete quinones that effects dosaged delivery of the mixture by brushing it on the assailant with the tips of its forelegs.
Collisionally-induced dissociation mass spectra of organic sulfate anions
The collisionally-induced dissociation mass spectra of a variety of organic sulfate ester anions are described and mechanistically rationalized. A cyclic syn-elimination pathway, analogous to that of
A cyanoallyl glucoside from Alliaria petiolata, as a feeding deterrent for larvae of Pieris napi oleracea.
TLDR
Feeding inhibition assays showed comparable activity for the synthetic and natural glycosides, and structural assignment was confirmed by synthesis of peracetylated alliarinoside and its 2E isomer.
