This study suggests that alkaloid deficiency inUtetheisa (Lepidoptera: Arctiidae) is a main cause of cannibalism; moreover, cannibalism can be predicted on the basis of alkaloid deficiency and of systemic alkaloid accumulation. This chemical plays a central role in the life of this species, because, first, it provides acquired chemical protection from potential predators, and, second, it determines mating success (as the alkaloid is an essential precursor of the male pheromone). Consequently… 

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.

Baculovirus-Induced Climbing Behavior Favors Intraspecific Necrophagy and Efficient Disease Transmission in Spodoptera exigua

It is concluded that, in addition to improving the dissemination of virus particles over plant foliage, baculovirus-induced climbing behavior increases the incidence of intraspecific necrophagy in S. exigua, which is the most efficient mechanism of transmission of this lethal pathogen.

Native Insects as a Framework for Understanding Potential Impacts of Exotic Species

It is shown that this South African citrus thrips can form self-sustaining populations on mango, grape, chilli, pea, green bean and blueberry, and that caution is needed before promoting this thrips as a biocontrol agent against the pasture weed.

Feeding on Host Plants with Different Concentrations and Structures of Pyrrolizidine Alkaloids Impacts the Chemical-Defense Effectiveness of a Specialist Herbivore

The protection against the spider was more effective in adults whose larvae fed on seeds, which had a higher PA concentration than leaves, and the results are partially explained by host plant phylogeny, since PAs of the host plants do have a phylogenetic signal which is reflected in the adult defense.

Mixed‐species aggregations in arthropods

This review offers the first synthesis of the research on mixed‐species groupings of arthropods and highlights the behavioral and evolutionary questions raised by such behavior, particularly the evidence for phylogenetic proximity between members that promotes cross‐species recognition.

Cannibalism in Natural Populations

It is shown that cannibalism is a normal phenomenon in many natural populations, to evaluate its possible roles in influencing demo­ graphic structure and population processes, and to suggest conditions for, and constraints on, its occurrence.

Chemical basis of egg cannibalism in a caterpillar (Utetheisa ornatrix)

It is argued that such feeding may occur only opportunistically in the wild, rather than as a matter of course, because presence of PA in the egg, while providing the egg with defense against predation, can increase its vulnerability to cannibalism.

It is suggested that cannibalism is potentially the most effective and homeostatic self-regulatory agent and is capable of contributing to the long term stability and persistence of populations.

Chemical basis of pupal cannibalism in a caterpillar (Utetheisa ornatrix)

Evidence is presented indicating that cannibalism in larvae is elicited not by hunger, but possibly by PA deficiency itself, and that in making cannibalistic choices larvae prefer PA-containing over PA-free pupae.

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.

Cannibalism in Phytophagous Argina cribraria Larvae and its Possible Significance

Most fifth instar Argina cribraria female larvae reared in paired groups on fresh sunnhemp leaves practised cannibalism on the male, causing profuse bleeding of haemolymph, immobility and contraction.

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.

A potential kairomone stimulates pheromone-responsive receptor neurons inUtetheisa ornatrix (Lepidoptera: Arctiidae)

The olfactory receptor neurons in basiconic sensilla on the antennae of Utetheisa ornatrix are shown to be responsive to volatile substances in samples of pyrrolizidine alkaloids (PAs), indicating the evolution of a signaling system with these properties.
