As many degrees of symbiosis, a phenomenon in which two unrelated organisms coexist over a prolonged period of time while depending on each other, occur, it is not easy to unequivocally define parasitism (Cheng, 1991). -

E-mail: [email protected] Abstract Prenolepis is a lineage of formicine ants with its center of diversity in the Old World tropics. Three more Prenolepis spe- cies are added to the Indomalayan and Australasian fauna and another is synonymized, bringing the total number of Pre- nolepis species worldwide to 19. Two new species are described: P. nepalensis from Nepal and P. lakekamu from Papua New Guinea, the latter being the first in the genus east of Wallace’s Line. Additionally, P. dugasi Forel (comb. rev.) from Vietnam is transferred from Nylanderia and redescribed. Based on morphology, each of the three species appears to be most closely-related to other species found predominantly in or nearest to their respective bioregions: P. nepalensis most resembles P. darlena, P. fisheri, and P. fustinoda; P. lakekamu bears strongest resemblance to P. jacobsoni, P. jerdoni, and P. subopaca; and P. dugasi most resembles P. melanogaster. Descriptions, illustrations and images are provided for all three species. -

The host-parasite genera Proformica-Rossomyrmex present four pairs of species with a very wide range of distribution from China to Southeastern Spain, from huge extended plains to the top of high mountains. Here we review (1) the published data on these pairs in comparison to other slave-makers; (2) the different dispersal ability in hosts and parasites inferred from genetics (chance of migration conditions the evolutionary potential of the species); (3) the evolutionary potential of host and parasite determining the coevolutionary process in each host-parasite system that we treat to define using cuticular chemical data. We find a lower evolutionary potential in parasites than in hosts in fragmented populations, where selective pressures give advantage to a limited female parasite migration due to uncertainty of locating a host nest. -

Wise Faculty of Life Sciences, Tel Aviv University, Tel Aviv 69978, Israel. E-mail: [email protected] ABSTRACT Cataglyphis ants comprise one of the most characteristic groups of insects in arid regions around the Mediterranean basin and have been intensively stud- ied over the last 30 years. These ants are central-place foragers and scaven- gers, single-prey loaders that have become a model for insect navigation using sophisticated visual orientation, having lost pheromone orientation. They are highly heat-tolerant ants that forage close to their critical thermal limit dur- ing the hottest hours of the day, with their long-chain cuticular hydrocarbons protecting them from desiccation. This is exemplified in two Cataglyphis species, each of which developed different mechanisms for counteracting extreme heat when foraging: polymorphism of workers vs. physiological and behavioral adaptations. Several species in this genus have also become a model for studying nestmate recognition mechanisms. The role of cuticular hydrocarbons and the postpharyngeal gland as a reservoir of hydrocarbons in nestmate recognition was initially discovered mainly in Cataglyphis, includ- ing the first experimental demonstration of the Gestalt model of nestmate recognition. -

Swingle (Tree-of-Heaven) in the Mid- Atlantic United States Jessica S. Thompson ABSTRACT To date little information has been collected on the pollination biology of Ailanthus altissima (Mill.) Swingle (tree-of-heaven), an invasive exotic in the U.S. This study was conducted to determine the insect pollinator fauna visiting A. altissima and to study general pollinator visitation patterns associated with the tree’s nectar profile. A list of taxa visiting trees within each of three sites was developed from collected insects. Overall, visitor assemblage was dominated by the soldier beetle Chauliognathus marginatus with large numbers of ants in the genera Formica, Prenolepis, and Camponotus. No major diurnal pattern was found for visitation of insect pollinators using instantaneous counts. The nectar composition, concentration, and amount of total sugars in the flowers of A. altissima and how these are related to tree gender and time of day were determined. Nectar was found to be sucrose-dominant with lower, but nearly equal amounts of fructose and glucose. Total amounts of sugar in male and female blossoms were not statistically different, however higher concentrations of sugar were found in males (40.7%) than in females (35.3%). -

Among the characters that are common to all Hymenoptera, The Paradox of Altruism perhaps the one that is of greatest interest to the topic of this article (even if it eventually turns out to be only of Queens mate and lay both haploid, unfertilized eggs and historical interest) is haplodiploidy, a term that indicates diploid, fertilized eggs. Workers are, by and large, sterile. In that males are haploid on account of developing parthe- some ant genera, such as , , and nogenetically from unfertilized eggs and females are dip- Pheidole Pheidologeton Sole- nopsis, workers have altogether lost their ovaries.

Even among those In any case, workers never or very rarely lay eggs when that are social, there is a very large variation in the degree their queen is alive so that they usually spend their whole lives working to assist their queen to reproduce, while of sociality. -
Distinct Chemical Blends Produced by Different Reproductive Castes in the Subterranean Termite Reticulitermes Flavipes
www.nature.com/scientificreports OPEN Distinct chemical blends produced by diferent reproductive castes in the subterranean termite Reticulitermes favipes Pierre‑André Eyer*, Jared Salin, Anjel M. Helms & Edward L. Vargo The production of royal pheromones by reproductives (queens and kings) enables social insect colonies to allocate individuals into reproductive and non‑reproductive roles. In many termite species, nestmates can develop into neotenics when the primary king or queen dies, which then inhibit the production of additional reproductives. This suggests that primary reproductives and neotenics produce royal pheromones. The cuticular hydrocarbon heneicosane was identifed as a royal pheromone in Reticulitermes favipes neotenics. Here, we investigated the presence of this and other cuticular hydrocarbons in primary reproductives and neotenics of this species, and the ontogeny of their production in primary reproductives. Our results revealed that heneicosane was produced by most neotenics, raising the question of whether reproductive status may trigger its production. Neotenics produced six additional cuticular hydrocarbons absent from workers and nymphs. Remarkably, heneicosane and four of these compounds were absent in primary reproductives, and the other two compounds were present in lower quantities. Neotenics therefore have a distinct ‘royal’ blend from primary reproductives, and potentially over‑signal their reproductive status. Our results suggest that primary reproductives and neotenics may face diferent social pressures.
