    Notes: Summary A fourteen-membered lactone,(R)-(Z,E)-9,11-octadecadien-13-olide, was isolated from extruded abdominal glands of a Neotropical, nymphalid butterfly,Heliconius pachinus (Lepidoptera). This compound was obtained from mature adults of both sexes, but was not detected in young adults or pupae.

    Notes: Summary Pollen dispersal by male and female Heliconius butterflies and hermit hummingbirds was examined in a natural population of the tropical vine Psiguria warscewiczii. Fluorescent dyes were used to track flowers visited by individual pollinators. Mean distance of pollen dispersal was significantly higher by males than by female Heliconius. Butterflies dispersed pollen greater distances than did hummingbirds. There were no significant differences in dispersal distance among species of Heliconius. The number of flowers or plants to which dye was dispersed was greater for Heliconius than for hummingbirds. The home range behavior and site specificity exhibited by Heliconius, together with the preference by most Heliconius species in the study site for Psiguria led us to examine the relationship between the butterflies' home range and its daily foraging among Psiguria. A Heliconius mark-recapture program was conducted simultaneously with the dye program. This study showed that individual butterflies, for which extensive recaptures were made, visited an area of Psiguria plants on any one day that corresponded to the area in which those butterflies were caught or observed. The area over which a butterfly moved was termed its home range; within home ranges relative movement by butterflies was estimated as the mean distance between sequential captures. This estimate differed significantly among species of Heliconius; males of all species moving greater distances than females.

    Notes: [Auszug] SIR - Exotic pest species often become dominant in alien ecosystems by escaping regulation by coevolved pathogenic and parasitic organisms1. Since arriving from its native Brazil around 1940 (ref. 2), the red imported fire ant (Solenopsis invicta) has decimated arthropod communities3 and occupied ...

    Description / Table of Contents: Résumé Passiflora mollissima Bailey, vigne introduite, pose un problème dans l'unique zone de forêts naturelles aux Hawaï. La lutte biologique est souhaitable mais la proximité de la culture deP. edulis f.flavicarpa Degener exige de recourir à des agents hautement spécifiques. Les lépidoptères heliconiines inféodés auxPassiflora peuvent satisfaire cette spécificité. Les potentialités des heliconiines en tant que ravageurs d'une part, et en tant qu'agents de lutte contre lesPassiflora d'autre part, sont examinées. Les essais préliminaires en laboratoire et les observations dans la nature sur les hôtes et la spécificité d'habitat de ces lépidoptères sont rapportés.
    Notes: Abstract The introduced vine,Passiflora mollissima (Bailey), poses a threat to unique natural forest areas in Hawaii. While biological control is desirable, the proximity of the crop plant,P. edulis f.flavicarpa Degener requires control agents to be highly specific.Passiflora-specialist heliconiine butterflies may exhibit this necessary specificity. We examine the potential for heliconiines as pests and control agents ofPassiflora and report preliminary laboratory and field observations on host and habitat specificity.
