A New Species of Palarus Latreille from Spain with a Comparative Study on Nesting Behavior and Larvae in the Genus (Hymenoptera: Sphecidae)
1992
Palarus almerienis n. sp. is described from Spain (including imago, larva, and nesting habits). P. confusus Turner, currently considered a subspecies of P. ambustus Klug, is raised to full species status. The most important differences among the three species involve sculpture of the mesopleuron. The geographical distribution of these three taxa is discussed. Females of P. almeriensis excavate unicellular nests and capture not only Hymenoptera (the usual prey of the genus), but also Diptera (Stratiomyiidae). They make temporary closures and store the prey in the gallery before transferring it to the cell, which they dig during provisioning. Several species of Diptera (Miltogramminae) are na…
Host detection and rate of parasitism by Acroricnus seductor (Hymenoptera: Ichneumonidae), a natural enemy of mud-dauber wasps (Hymenoptera: Sphecida…
2011
Abstract The behavioural ecology of ichneumonid wasps that attack aculeate Hymenoptera is still largely unknown. Field observations and morphological analyses were devoted to investigate host detection and rate of parasitism by Acroricnus seductor (Scopoli), a natural enemy of the black and yellow mud dauber wasp Sceliphron caementarium (Drury). At the study site, about half of the host nests suffered parasitism by A. seductor. No significant difference was found between the rate of parasitism in sheltered (inside human building) and unsheltered (outside building) nests. Larger nests did not suffer a higher rate of parasitism, and larger brood cells were not more likely to be parasitized. …
Evaluating the quality of the Mexican fruit-fly, Anastrepha ludens, as host for the parasitoid Melittobia digitata
2013
We investigated the presence of Melittobia digitata (Hymenoptera: Eulophidae) and its associations with its natural hosts in Veracruz, Mexico. The parasitoid was confirmed to be present and found to attack prepupae of Trypoxylon and Sceliphron (Hymenoptera: Crabronidae and Sphecidae, respectively) mud daubers as well as pupae of the Mexican fruit fly Anastrepha ludens (Diptera: Tephritidae). Since A. ludens is a very important pest of citrus and mango in Mexico and Central America, we evaluated, in laboratory experiments, the quality of A. ludens as host of M. digitata comparing the development of the parasitoid in another unrelated fly species (Sarcophaga [Neobellieria] bullata) (Diptera: …
