“…In conclusion, metapopulation structure in monophagous herbivores of prairie species in the fragmented Iowa landscape may be restricted largely to sedentary species that use host plants that are predictable in space and time. For example, the weevil Rhynchites bicolor bicolor Fabricius is probably sedentary like most weevils and feeds on a few closely related species in the genus Rosa , another group of long‐lived, shrubby plants of prairies (Balduf, 1959). In general, prairie plant species such as Amorpha canescens that are intolerant of disturbance may harbour sedentary species such as Anomoea laticlavia that potentially function as metapopulations.…”

1. Dispersal capabilities of organisms are critical in determining the landscape population structure of species as well as their likelihood of survival in fragmented landscapes. Using mark-recapture techniques on the monophagous weevil Rhyssomatus lineaticollis Say (Curculionidae), within-and between-patch dispersal capabilities, landscape level population structure, and the role of beetle density and host patch characteristics in setting distances, amounts, and timing of dispersal were studied.2. The data indicate that R. lineaticollis is sedentary, with 50% of recaptured beetles moving <1 m and the maximum distance moved <1 km. Within-and between-patch movement of beetles was unrelated to host plant patch characteristics and beetle densities.3. Despite limited dispersal, R. lineaticollis probably functions as a patchy population in east-central Iowa, U.S.A. because dispersals between patches are common and because all host patches surveyed contained this herbivore, indicating a lack of suitable vacant patches, a prerequisite for metapopulation structure.4. Between-patch distances are well within the dispersal capabilities of R. lineaticollis, although this may be the result of an increase in the density of patches of its host, Asclepias syriaca, in the landscape over the last 150 years as a result of human disturbance and this species' weedy habit.5. Metapopulation structure in monophagous prairie herbivores may be most likely in species whose non-weedy host plants form highly predictable resources in space and time, but which are now widely scattered in habitat fragments.

“…Mating in caddisflies is poorly known, and female attractant pheromones have only recently been discovered, but they are now known to occur in three of the four infraorders (Solem & Petersson, 1987;Bjostad, Jewett & Brigham, 1996). Male swarming also occurs in many species in this order (Downes, 1969;Sivinski & Petersson, 1997), and mating pairs escape from possible harassment by leaving the swarm (Davis, 1934;Balduf, 1939;Petersson, 1989), so the females of many Trichoptera are probably protected. Nevertheless, male genitalia are extremely elaborate, and are species-specific throughout this order (Mosely, 1939;Malicky, 1983;Neboiss, 1986) (Fig.…”

Male–female conflict and genitalia: failure to confirm predictions in insects and spiders

Some recent models suggest a new role for evolutionary arms races between males and females in sexual selection. Female resistance to males is proposed to be driven by the direct advantage to the female of avoiding maleimposed reductions in the number of offspring she can produce, rather than by the indirect advantage of selecting among possible sires for her offspring, as in some traditional models of sexual selection by female choice. This article uses the massive but hitherto under-utilized taxonomic literature on genitalic evolution to test, in a twostep process, whether such new models of arms races between males and females have been responsible for rapid divergent evolution of male genitalia. The test revolves around the prediction that 'new arms races' are less likely to occur in species in which females are largely or completely protected from unwanted sexual attentions from males (e.g. species which mate in leks or in male swarms, in which males attract females from a distance, or in which females initiate contact by attracting males from a distance).The multiple possible mechanical functions of male genitalia are summarized, and functions of male genitalic structures in 43 species in 21 families of Diptera are compiled. Functions associated with intromission and insemination (e.g. seizing and positioning the female appropriately, pushing past possible barriers within the female, orienting within the female to achieve sperm transfer), which are unlikely to be involved in new arms races when females are protected, are shown to be common ( > 50 % of documented cases). This information is then used to generate the new arms race prediction: differences in genitalic form among congeneric species in which females are protected should be less common than differences among congeneric species in which females are vulnerable to harassment by males. This prediction was tested using a sample of 361 genera of insects and spiders. The prediction clearly failed, even when the data were adjusted to take into account several possible biases. Comparative analyses within particular taxonomic groups also failed to show the predicted trends, as did less extensive data on other non-genitalic male display traits. Arms races, as defined in some recent models, seem to have been less important in male•female coevolution of genitalic structures than has been suggested. By elimination, alternative interpretations, such as traditional female choice, which do not predict associations between female protection from harassment and rapid divergent evolution, are strengthened.

“…Biological control might offer a long‐term, viable solution to R. multiflora management: one macro‐organism and one disease have been identified as having the potential to provide biological suppression of R. multiflora . The first is Megastigmus aculeatus (Hymenoptera; Torymidae), whose larvae feed in R. multiflora seeds (Balduf 1959). The second is rose rosette disease (RRD), a disease with unknown etiology and uncertain classification, which reduces plant vigor and eventually kills R. multiflora .…”

Rosa multiflora Thunb. (Rosaceae) is an invasive species in the USA, where it grows in pastures and wooded areas. A disease of unknown etiology, rose rosette disease (RRD), infects R. multiflora and other Rosa spp. The goal of this research was to determine the effects of habitat and disease symptoms on the abundance of Phyllocoptes fructiphilus Keifer (Acari: Eriophyidae), the presumed vector of RRD, and other arthropods on R. multiflora. We collected branch tips from healthy R. multiflora plants growing in the sun and shade, as well as RRDinfected R. multiflora growing in the sun. The samples were collected from June 2002 to April 2004 from three sites in Iowa, USA. The samples were collected approximately every 2 weeks during the summer, monthly during the fall, and once during early spring. The fall samples were only taken from RRD-infected plants because they retain leaves throughout the winter. We found that P. fructiphilus was present on diseased and healthy R. multiflora growing in the sun and on healthy R. multiflora growing as understory plants under a tree canopy (shaded), but the greatest numbers were observed on the diseased plants growing in the sun. Several other mite species, both predatory and phytophagous, Chaetosiphon sp. aphids, and the thrips species, Frankliniella exigua Hood and Neohydatothrips variabilis Beach, occur in the same plant microhabitat as P. fructiphilus. This is the first study to document the presence of additional arthropods in the same microhabitat (branch tips) as P. fructiphilus. Future research needs to isolate and identify the causal agent of RRD so it can be confirmed that, of the many arthropods feeding on R. multiflora, only P. fructiphilus vectors RRD.
