Defensive droplets from glandular hairs of the pupa of the Mexican bean beetle, Epilachna varivestis, contain a group of structurally novel alkaloids, the azamacrolides. The major constituent of this secretion, epilachnene, is shown to be (5Z)-11-propyl-12-azacyclotetradec-5-en-14-olide. The secretion also contains an epilachnadiene and trace amounts of three closely related components.

Antiinsectan Activity of Epilachnene, a Defensive Alkaloid from Pupae of Mexican Bean Beetles (Epilachna varivestis)
Both the R enantiomer of epilachnene, and the natural configuration of the compound, proved deterrent in a feeding bioassay with a predaceous coccinellid beetle (Harmonia axyridis) and in a topical irritancy test with a cockroach.
Miriamin, a defensive diterpene from the eggs of a land slug (Arion sp.).
The eggs of the land slug Arion sp. contain a diterpene, miriamin, characterized as a polyoxygenated geranylgeraniol derivative. In bioassays with a coccinellid beetle, Harmonia axyridis, miriamin
Mayolenes: Labile defensive lipids from the glandular hairs of a caterpillar (Pieris rapae)
In bioassays with the ant Crematogaster lineolata, the secretion of the European cabbage butterfly was shown to be potently deterrent, indicating that the fluid plays a defensive role in nature.
It is demonstrated that the secretion of this introduced beetle serves as a potent antipredator defense: contact with it elicited pronounced cleaning activity by the predatory ant Crematogaster lineolata, and application of the secretion to palatable food items rendered them unacceptable to the ant.
Combinatorial chemistry in insects: a library of defensive macrocyclic polyamines.
The pupal defensive secretion of the coccinellid beetle Epilachna borealis is composed principally of a combinatorial library of macrocyclic polyamines. These compounds constitute a previously
Biparental Endowment of Endogenous Defensive Alkaloids in Epilachna paenulata
Biparental endowment of chemical defenses into eggs has been shown previously in insects that acquire defensive compounds from dietary sources, but this is the first report of biparental egg endowing of endogenous defenses.
The Use of Gyrinids and Dytiscids for Stimulating Breast Growth in East Africa
The use of whirligig beetles and predaceous diving beetles for stimulating breast growth in East Africa is a unique traditional practice and the beetles secrete defensive substances which are produced in special glands to discourage possible vertebrate predators.
Ladybird defence alkaloids: Structural, chemotaxonomic and biosynthetic aspects (Col.: Coccinellidae)
The defensive mechanisms which protect ladybird beetles (Coccinellidae) against predators are reviewed, and particular emphasis is laid on the repellent alkaloids which are contained in the haemolymph of many species.
Chemical defense of the ladybird beetle Epilachna paenulata
Comparative studies of the defensive chemistry of eggs, larvae, pupae and adults showed both qualitative and quantitative differences in alkaloid composition among the four life stages, and also within adult age.
Polyazamacrolides from ladybird beetles: ring-size selective oligomerization.
Comparing this alkaloid mixture with that of the pupal defensive secretion in related ladybird beetle species indicates that the degree of oligomerization of the 2-hydroxyethylamino carboxylic acid building blocks can be carefully controlled by the insects.


Hemorrhage in a Coccinellid Beetle and Its Repellent Effect on Ants
Special refinements of the bleeding mechanism of the Mexican bean beetle are described, and the defensive effectiveness of the mechanism against ants is demonstrated, suggesting that Ants may have provided a major selective force in the evolution of this mechanism.
