Abstract:
... Brochosomes are ultramicroscopic particles produced in large quantities by the Malpighian tubules of leafhoppers (Insecta, Hemiptera, and Cicadellidae) and applied by leafhoppers as a coat to their integuments. A recent study has described brochosomes on museum specimens of Heteroptera and Psylloidea, suggesting a wider distribution of brochosomes among Hemiptera. Here, I report that the majority ...

Locusta migratoria; Schistocerca gregaria; grasshoppers; locusts; migratory behavior; models; phase transition; phylogeny; polyphenism
Abstract:
... Although the specific mechanisms of locust phase transformation are wellunderstood for model locust species such as the desert locust Schistocerca gregaria and the migratory locust Locusta migratoria , the expressions of density-dependent phase polyphenism in other nonmodel locust species are not wellknown. The present paper is an attempt to review and synthesize what we know about these nonmodel ...

Abstract:
... The responses of adult solitarious desert locust to odors from a host plant were evaluated in a two-choice wind tunnel. Solitarious desert locusts collected from the field (Red Sea Coast) were more attracted to volatiles from potted Heliotropium ovalifolium in scotophase than in photophase. The attraction towards the host plant odors rather than to clean air, in both photophase and scotophase, con ...

The monotypic genus Paracyphoderris Storozhenko and at least 13 species are endemics or subendemics. About 50 species are known from boreal North America. Four endemic species are distributed very locally. Relationships between t ...

Abstract:
... The genus Mischocyttarus comprises 245 species of neotropical basal eusocial wasps. They form small colonies (rarely more than few tens of individuals); castes are morphologically undifferentiated and determined behaviorally by agonistic interactions. The aim of this study was to verify the effects of the experimental disruption of social hierarchy on foraging activity of Mischocyttarus cerberus s ...

More than one thousand hoppers were collected and described according to a semiquantitative method. A typology is proposed, strictly reflecting the increase in population densities. This correctly translated the progressive evolution of a solita ...

Many social bees exhibit this behavior, but scent-marking is absent in social wasps, except for Vespa mandarinia . We tested for scent marking in the swarm-founding wasp, Polybia occidentalis . This wasp has moderately large colonies and utilizes resources that are concentrated in time and space, making s ...

Atta; body size; evolution; foraging; information exchange; insect communication; paper
Abstract:
... Sequential transport of plant fragments was studied in the grass-cutting ant Atta vollenweideri . Two competing hypotheses concerning its occurrence were tested. Based on the “economic-transport hypothesis," sequential transport occurs because of a mismatch between load size and ant body size, and it is therefore considered a way to improve size-matching and so the plant delivery rate. Alternative ...

Abstract:
... Chemical trails have been shown to act as an orientation cue in some ant species. Here, I report that the trail-laying behaviour in the nectar-feeding ant, Camponotus rufipes , varies with the concentration of the sucrose solutions collected. Single workers collected solutions of different sucrose concentrations (5%, 20%, and 40% in weight) during 4 consecutive visits to the resource, and their tr ...

Pteromalus puparum is a gregarious pupal endoparasitoid wasp which has evolved unique means to adopt the host's immune system, as no other parasitoid-associated factors other than venom are injected into its hosts during oviposition. It represents an excellent mo ...

Abstract:
... Foraging behavior in social wasps is important in the development of the colony and reflects an important ecological interaction between the colony and the environment. Although the social traits of the colony play a role in the foraging activities, the conditions that establish the space and time limits are mainly physical. Here, we evaluate colonies of Polybia paulista throughout one year in ord ...

Abstract:
... Bees acquire wing damage as they age, and loss of wing area affects longevity and behaviour. This may influence colony performance via effects on worker behaviour. The effects of experimental wing damage were studied in worker honeybees in observation hives by recording survivorship, how often and for how long bees foraged, and by decoding waggle dances. Mortality rate increased with both age and ...
