-The biology and ecological importance of Hawaiian endemic Cydia spp. (Lepidoptera: Tortricidae) are poorly known. Cydia larvae arc an important food to palila, an endangered Hawaiian bird that inhabits Sophora woodlands on Mauna Kea, Hawaii. We quantified Cydia larval abundance in seeds of Sophora chrY~'ophylla Salisbury (Fabaceae) and larval mortality caused by parasitism. Four new host plant...

The study was conducted on fruit trees where bands of corrugated cardboard were attached around the trunks of the trees, which were used to catch the larvae of overwintering generation of the rufous-tipped swammerdamia moth, Swammerdamia pyrella (Villers) (Lepidoptera: Yponomeutidae). Twenty-five species of parasitic Hymenoptera have been described from S. pyrella in Poland including the report...

Female Edovum puttleri Grissell [Hymenoptera: Eulophidae], reared from eggs of Leptinotarsa decemlineata (Say) or Leptinotarsa texana Schaeffer [Coleoptera: Chrysomelidae], were videotaped as they attacked egg masses of L. decemlineata containing 20 host eggs. We identified 15 components of ovipositional behavior. Parasitoids reared on L. texana attacked and oviposited in significantly more hos...

Numerous species of gall midges (Diptera: Cecidomyiidae) have been recorded from saltbush (Chenopodiaceae: Atriplex) around the world but only 11 of them belong to the large cecidomyiid genus Asphondylia. Of these, two species were described in the late 19th century from complex bud galls on Atriplex halimus in the Mediterranean Basin. In the present study Asphondylia punica is redescribed, A. ...

Ratzeburgiola Erdös is a small but phylogenetically interesting genus exhibiting a combination of characters once used to define both the former tribes Elachertini and Eulophini of the subfamily Eulophinae (Hymenoptera: Chalcidoidea: Eulophidae). It was once classified in the tribe Elachertini with genera having scutellar grooves and complete notauli, but in some characters it resembles the gen...

A survey was conducted in Iran, on xylophagous beetles, to collect and determine their associated chalcidoid parasitoids (Hym.: Chalcidoidea). Nineteen species of parasitoids are recorded. These species are from 6 families: Chalcididae, Encyrtidae, Eulophidae, Eupelmidae, Eurytomidae and Pteromalidae belong 4, 1, 1, 2, 4 and 7 species, respectively. Five species were discovered as new record fo...

Chemical signals used by parasitoids to Þnd hosts often originate from the host, its habitat, or both, providing critical cues for locating hosts that are often cryptic or highly dispersed. MelittobiaWestwood are gregarious ectoparasitoids, which primarily attack Trypoxylon politum Say prepupae.HowMelittobia locates its host is unknown, but itmay involve host-related chemical signals. Therefore...
