Larvae of the mothUtetheisa ornatrix are shown to cannibalize eggs in the laboratory. They proved most cannibalistic if they were systemically deficient in pyrrolizidine alkaloid (PA), the defensive agent that protectsUtetheisa at all stages of development against predation, and whichUtetheisa acquire as larvae from their food plant. In exercising cannibalistic choice,Utetheisa larvae feed preferentially on eggs that are PA-Iaden rather than PA-free. Egg cannibalism can therefore… 

Causes and consequences of cannibalism in noncarnivorous insects.

Cannibalism can be adaptive by improving growth rate, survivorship, vigor, longevity, and fecundity, and it also can play an important role in regulating population density and suppressing population outbreaks, stabilizing host plant-insect relationships, and reducing parasitism rates.

The frequency of cannibalism by Spodoptera frugiperda larvae determines their probability of surviving food deprivation

Evidence of cannibalism is usually associated with higher population density, or lower food plant quality, and has been reported in half of all terrestrial, herbivorous insects. However, we found

Cannibalism of Pupae by Caterpillars of the Ranchman's Tiger Moth, Arctia Virginalis, (Lepidoptera: Erebidae)

This work investigated the cannibalism of pupae by caterpillars of the ranchman's tiger moth, Arctia virginalis based on an observation of a late instar caterpillar attacking the pupa of a conspecific in the laboratory and conducted separate laboratory and field experiments to confirm this observation and determine the propensity for cannibalism under more natural conditions.

Interspecific advantage results in intraspecific disadvantage: Chemical protection versus cannibalism inUtetheisa ornatrix (Lepidoptera: Arctiidae)

Cannibalism may be expected to have general ecological importance in the evolutionary play of Utetheisa and may contribute to a balanced regulation of the acquired alkaloid contents in these arctiid populations.

Pyrrolizidine alkaloid deters ant predators of Utetheisa ornatrix eggs: effects of alkaloid concentration, oxidation state, and prior exposure of ants to alkaloid-laden prey

The data provide the first demonstration of such long-term avoidance of chemically protected lepidopteran prey by an invertebrate, and has important ramifications to egg-laying strategies of female Utetheisa, both in terms of the dispersion of eggs, and the extent to which eggs are provisioned with alkaloid.

Stadium‐specific transmission of endosymbionts needed for pederin biosynthesis in three species of Paederus rove beetles

Lack of intrinsic biosynthesis after ingestion of endosymbionts indicates that these are not biosynthetically active within the gut and have to reach an unknown internal location before completion of metamorphosis.

Selective Sequestration of Pyrrolizidine Alkaloids from Diverse Host Plants by Longitarsus Flea Beetles

In 11 species of the flea beetle genus Longitarsus, whether the insects sequester the pyrrolizidine alkaloids present in their host plants of the families Asteraceae and Boraginaceae is investigated, and data indicate that the PAs found in the beetles are largely determined by the host plant.

Effect of light stress on Crotalaria spectabilis (Fabaceae) and on its herbivore insect, the moth Utetheisa ornatrix (Erebidae: Arctiinae)

Whether plants stressed by shading differ from non-stressed plants in terms of productivity, morphological characteristics and water percentage is verified and the Plant Stress Hypothesis is corroborated by two tested variables: number of trichomes and larval survival.

The Plant Stress Hypothesis predicts that stressed plants are more attacked by herbivorous insects. In this work, we investigated the influence of light stress on Crotalaria spectabilis Roth

Temporal Modulation of Pyrrolizidine Alkaloid Intake and Genetic Variation in Performance of Utetheisa ornatrix Caterpillars

It is demonstrated that an herbivorous insect can temporally vary its intake of sequestered allelochemical, and modulation of intake rate by caterpillars may be an important mechanism to reduce effects on the growth and fitness of individuals.



Biparental defensive endowment of eggs with acquired plant alkaloid in the moth Utetheisa ornatrix.

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.

Unpalatability of the pyrrolizidine alkaloid-containing moth, Utetheisa ornatrix, and its larva, to wolf spiders

Experiments demonstrating that Utetheisa, as larvae and adults, are protected against wolf spiders are reported.

Courtship pheromone production and body size as correlates of larval diet in males of the arctiid moth,Utetheisa ornatrix

Hydroxydanaidal, the corematal courtship pheromone of maleUtetheisa ornatrix, shows pronounced quantitative variation in natural populations of the moth, and could be used to gauge both the alkaloid content and body weight of their suitors.

Paternal allocation of sequestered plant pyrrolizidine alkaloid to eggs in the danaine butterfly,Danaus gilippus

Pyrrolizidine alkaloid sequestered by adult maleDanaus gilippus from plants is transferred in large measure to the female at mating, and by the female to the eggs. The eggs, presumably, are protected

Reinvestigation of oak leaf roller sex pheromone components and the hypothesis that they vary with diet.

The sex pheromone of the oak leaf roller, Archips semiferanus, was identified as a specific blend (67:33) of trans-11- and cis- 11-tetradecenyl acetates, which conflict with the hypothesis that the composition and perception of month sex phersomones vary with slight changes in diet.

Methods are described for converting alkaloids having the dehydropyrrolizidine ring, and their N-oxides, to dihydropyrrolizine derivatives, which are also formed as metabolites when the alkaloids are
