    Description / Table of Contents: Zusammenfassung Weibchen jeden Alters, Kasten als wohl als solche mit früherer Kopulationserfahrung verursachten geschlechtliches Verhalten bei Männchen der sozialen WespePolistes fuscatus (F.). Gifte der Arbeiter, Königinnen, unbefruchteten Weibchen 〉 24 Stunden alt und befruchtete Weibchen 〉 14 Tage alt waren wirksam und riefen männliches sexual Verhalten hervor. Aus diesem Grunde enthalten diese Gifte Geschlechtspheromone. Gift von Weibchen 〈 15 h alt riefen kein heufigeres Geschlechtsverhalten hervor als Kontrol-Weibchen.
    Notes: Summary Females of all ages, castes, and prior mating experiences elicited sexual behavior in males of the social waspPolistes fuscatus (F.). The venoms of workers, queens, uninseminated gynes more than 24 hours old, and inseminated gynes more than 14 days old were effective in stimulating male sexual behavior, and thus contained sex pheromone. The venom of gynes less than 15 hours old did not stimulate a significantly greater frequency of male sexual behavior than did the control.

    Description / Table of Contents: Zusammenfassung Männliche Sternaldrüsen sind beschrieben für 28 Wespenarten von 12 polistinen Gattungen. Drüsen und zugehörene kutikulare Änderungen dieser und früherer beschreibten Männchen wurden mit Drüsen der konspezifischen Weibchen verglichen. Es stellte sich heraus, dass Männchen in 4 schwärmenden Gattungen Drüsen haben, die morphologisch und örtlich denen der Weibchen ähnlich sind. Diese Drüsen haben Kanäle, welche entweder mit aufrechten Schuppen am vorderen Rand des fünften Sterniten (Metapolybia, Chartergus, undPolybia) oder mit einem Band von Haaren an dem vorderen Rand des vierten und füften Sterniten (Apoica) versehen sind. Männchen vonRopalidia montana haben Kanal-Zellen auf dem fünften und sechsten Sterniten, während Weibchen solche nur auf dem sechsten Sterniten haben. Bei Männchen vorBrachygastra augusti sind Kanal-Zellen auf dem fünften, sechsten und siebten Sterniten zu finden, während die Weibchen solche nur auf dem fünften haben. Im gegensatz zu Weibchen, haben diese Drüsen keine abgeänderte Kutikula. Arten, die zu den anderen drei Schärmenden Gattungen gehören, zeigen bei Männchen keine Sternaldrüsen vor. Männchen von Gattungen, die Kolonien unabhängig gründen (Mischocyttarus, Polistes, Belonogaster, Parapolybia), haben Drüsenzellen die den hinteren 2/3 oder halben Teil des Sterniten bedecken, während bei Weibchen, diese Drüsenzellen am vorderen Teil des Sternits vorkommen.
    Notes: Summary The sternal glands of 28 species of male wasps belonging to 12 polistine genera are described. Glands and associated cuticular modifications of these males and of males described in past studies are compared to those of conspecific females. Males in species of four swarm-founding genera have glandular areas similar in morphology and location to those of females. The glands are comprised of ducted cells associated with either a bed of erect cuticular scales along the anterior edge of the fifth sternite (Metapolybia, Chartergus, andPolybia) or a band of hairs along the anterior margin of both the fifth and sixth sternites(Apoica). Ropalidia montana males have ducted gland cells on sternites five and six, rather than just on six as in congeneric females;Brachygastra augusti males have them on sternites five through seven, rather than just on five as in their conspecific females. Also unlike those of conspecific females, these glands are not associated with any cuticular modification. Species in the remaining three swarm-founding genera lack male sternal glands. Males of independent-founding genera (Mischocyttarus, Polistes, Belonogaster, andParapolybia) have glandular cells covering the posterior 2/3 or 1/2 of the sternite, rather than the anterior portion as in their congeneric females.

    Description / Table of Contents: Zusammenfassung Qualitative Unterschiede im Nestbau von 12Polistes-Arten werden beschrieben. Die Waben vonFuscopolistes spp.,P. Palisotius major undP. Epicnemius pacificus waren horizontal angelegt, sie hatten entweder eine ovale oder runde Form mit einem zentralen Pedicellus; dagegen waren die Waben vonP. Aphanilopterus spp. tropfenförmig mit einem azentralen oder seitlichen Pedicellus. Der Winkel zwischen Pedicellus und Substrat betrug bei allen Arten ungefähr 90°. Die vierFuscopolistes-Arten bauten die erste Zelle in der Regel vertikal ungeachtet der jeweiligen Neigung des Substrats, wodurch der Winkel zwischen Nest und Substrat verkleinert wurde. Im Gegensatz dazu wurde bei den sechs untersuchtenAphanilopterus-Arten der Winkel zwischen Nest und Substrat durch die Anlage der ersten Zelle vergrößert. Der mittlere Zellendurchmesser war mit der Kopfbreite signifikant korreliert. Alle Arten hörten mit der Verlängerung der Zellen auf, sobald die darin befindlichen Larven sich verpuppt hatten.P. Aphanilopterus canadensis (Brasilien) besaß den größten mittleren Divergenzwinkel der Zellen, sie war auch die einzige der untersuchten Arten, die ihre Nester regelmäßig in Form kleiner, eng benachbarter Waben baute. Bei vielen Arten änderte sich der Winkel zwischen der Wabe und dem Pedicellus im Verlauf des Nestbaus. Arten der gemäßigten Klimazonen tendierten dazu, den Pedicellus zu verstärken, sie bauten sekundäre Pedicellen und fügten auch Baumaterial dem Substrat an. Ob Baumaterial auf den Puppendeckel und auf die Rückseite der Wabe angebracht wurde, war bei den Arten ebenso variabel wie die Festigkeit und die Farbe der Nester und die Form der Rückseite der Zellen.
    Notes: Summary Measurements were taken from the nests of 12 species ofPolistes wasps and qualitative differences described. The combs of theFuscopolistes spp.,P. Palisotius major andP. Epicnemius pacificus were horizontal and either oval or round with a central petiole, while those of theP. Aphanilopterus spp. were tear-shaped with eccentric or lateral petioles. For all species the angle of the petiole to the substrate was close to 90°. The fourFuscopolistes species usually built the first cell vertically, regardless of the substrate angle, and thus reduced the angle of the nest. In contrast, the angle of the first cell increased the nest angle of the 6Aphanilopterus species studied. A regression of average cell diameter on headwith was significant. All species stopped lengthening cells after larvae pupated in them.P. (A.) canadensis (Brazil) exhibited the greatest average angle of cell divergence and was also the only wasp investigated that regularly built its nest a several small combs in close proximity. In many species the comb angle with respect to the petiole changed during construction. Temperate species tended do add more pulp to the petiole of the nest than did tropical species, built secondary petioles, and added pulp to the substrate. Whether or not pulp is added to pupal caps and comb back, paper strength and color, and the shape of cell backs were also variable among species.

    Notes: Summary Polybia sericea (Olivier) (Hymenoptera: Vespidae) foragers were trained to visit experimental foraging plots and tests were conducted to determine the role of visual, olfactory, and chemotactile cues in prey location. Foragers approached prey from downwind and hovered downwind of visual and olfactory stimuli. Olfactory cues were more likely to elicit landing than were visual cues. Biting of potential prey was most consistently elicited by a combination of visual, tactile, and chemotactile cues. Foragers encountering large prey carried a piece back to the nest and returned for prey remains. These returning foragers used visual cues to direct intensive aerial search; olfactory prey cues elicited landing.

    Notes: Abstract Polistes fuscatus variatus (a north temperate wasp) andP. instabilis (a tropical wasp) begin building their nests by applying pulp in a linear sequence of steps: surface preparation, petiole, flat sheet, first cell. After the initiation of first cell there are multiple locations for pulp addition (petiole, new cell, old cell), which become increasingly varied inP. fuscatus as the nest grows (secondary petioles, comb back, substrate, and pupal caps). AlthoughP. fuscatus also adds oral secretion to the petiole, comb back, and pupal caps,P. instabilis only applies oral secretion and no pulp to these locations and does not build secondary petioles or place pulp on the substrate. Both species show a similar series of behavioral acts leading from pulp foraging to application. In both species queens initiate more cells than do subordinates; nonetheless, subordinates account for a large percentage of initiated cells. During pre-emergence and early post-emergence the majority of pulp is used for cell lengthening. BothP. instabilis andP. fuscatus show a bimodal pattern of growth in cell number. The numbers of cells in a mature comb at the end of the nesting cycle are similar in both species (P.f.=274.4 andP.i.=282.6 cells).
