  ABSTRACT: This paper provides a synthesis of the ecological impact of phorid fly parasitoids on ants. We find the most important impact of phorids on ants to be trait-mediated effects. Phorids diminish the foraging activity of ants, frequently reducing the number and average size of foragers and reducing the amount of food retrieved by a colony. However, ants' coping mechanisms include changing foraging site and time. Phorids can also affect competition, especially through changes in the ability of the host to win in exploitative competition. Factors such as microclimate, resource size, and habitat complexity interact with phorids to change their effect on competition. By being highly specific and attacking ants high in the competitive hierarchy, phorids can alter the linear nature of the competitive transitivity, and by reducing the number of foragers, they can change the discovery-dominance tradeoff that is observed in some ant communities. Trait-mediated effects of phorids also cascade to other trophic levels. As an example, we discuss the trait-mediated cascade of phorids on the Azteca instabilis system in coffee. In this system, by reducing the foraging activity of A. instabilis, phorids reduce the direct and indirect biological control impact of the ant in the coffee agroecosystem.

• Article: A System for Harvesting Eggs from the Pink-Spotted Lady Beetle

  ABSTRACT: Abstract We describe a system for harvesting eggs from a predatory insect, the pink-spotted lady beetle, Coleomegilla maculata De Geer (Coleoptera: Coccinellidae). Adult beetles placed in square, transparent containers that included oviposition substrates hanging from the top of the cage deposited eggs on the materials provided. We harvested eggs from these substrates in quantities sufficient for either destructive sampling or synchronous development of larvae. We evaluated effects of crowding inside cages; effects of a chemical attractant on oviposition behavior; egg cannibalism. Females preferred a textured surface rather than a smooth, waxy one for laying eggs. Crowding inhibited oviposition of beetles. Presence of a chemical attractant (methyl salicylate) did not significantly improve oviposition. This paper describes an inexpensive system for harvesting eggs from C. maculata. Refinement of this system should improve oviposition and reduce cannibalism.

  ABSTRACT: Six species of genus Athesapeuta Faust (Coleoptera: Curculionidae: Baridinae) from India and the adjacent countries are included, of which three new species, namley meghalayensis sp. nov., richardi sp. nov., and spinulatus sp. nov., are described. An annotated checklist of known species along with their synonymy and distribution is given. Descriptions are supplemented with details of genitalia and elytral vestiture; a key to the species studied is provided.

• Article: Grundlegende Merkmale interpersonaler, intersubjektiver und relationaler Ansätze als Ausdruck aktueller Entwicklungstendenzen in der Psychoanalyse

  ABSTRACT: Essential features of interpersonal, intersubjective, and relational approaches as an expression of present-day tendencies in psychoanalysis. – First the author traces the change over time in the understanding of psychoanalytic treatment from traditional one-person psychology to modern, fully developed two- or three-person psychology. 616 dieter KUnfflKe His approach takes the form of (1) a historical and critical engagement with drive theory, (2) an account of the innovations of object relations theory and self-psychology, and (3) an outline of contemporary views of an interpersonal, intersubjective, and relational nature. The latter persuasions are then described in detail and compared, with especial reference to their far-reaching implications for the analytic relationship, therapeutic practice, and psychoanalytic attitude. The interpersonal model is given a little less space, as it is more closely associated with traditional psychoanalysis, which is not the primary subject of the article.
