Biology, Ecology & Systematics Of Australian Scelio: Wasp Parasitoids Of Locust And Grasshopper Eggs

Taxonomy , biology , and efficacy of two Australian parasitoids of the eucalyptus gall wasp ,

Two species of Tetrastichinae (Hymenoptera: Eulophidae) from Australia are described as parasitoids of Leptocybe invasa Fisher & La Salle: Quadrastichus mendeli Kim & La Salle sp.nov. and Selitrichodes kryceri Kim & La Salle sp. nov. These parasitoids were introduced to Israel as part of a biological control program to counter the severe levels of damage caused by L. invasa to Eucalyptus planta...

Systematics and biology of the aberrant intertidal parasitoid wasp Echthrodesis lamorali Masner (Hymenoptera : Platygastridae s.l.): a parasitoid of spider eggs

The platygastroid wasp Echthrodesis lamorali has been of considerable interest since its description in 1968, primarily because of its highly modified, densely pilose, wingless body, its distribution and unusual biology. The species is endemic to the Cape Peninsula, South Africa, where it is an endoparasitoid of eggs of the marine spidersDesis formidabilis (Desidae) and Amaurobioides africanus ...

Systematics of Old World Odontacolus Kieffer s.l. (Hymenoptera, Platygastridae s.l.): parasitoids of spider eggs

The genera Odontacolus Kieffer and Cyphacolus Priesner are among the most distinctive platygastroid wasps because of their laterally compressed metasomal horn; however, their generic status has remained unclear. We present a morphological phylogenetic analysis comprising all 38 Old World and four Neotropical Odontacolus species and 13 Cyphacolus species, which demonstrates that the latter is mo...

Can we make locust and grasshopper management sustainable ?

Scale is the fundamental conceptual problem in assessing the sustainability or value of controlling grasshoppers or locusts. Using case studies from North America (United States: Wyoming), Africa (Eritrea), and Asia (Russia: Irkutsk), we analyzed the viability of control programs. There are at least four dimensions to acridid pest management. At the geopolitical scale, all three cases reveal th...
