Abstract Experiments were conducted in Ash-Shoubak area of Jordan from June 2003 to September 2005 to study the effect of three apple rootstocks on the development of the small red-belted clearwing borer, Synanthedon myopaeformis (Borkh.) (Lepidoptera: Sesiidae), under field conditions. Mondial Gala apple trees grafted on the dwarfing rootstock M9 and the semi-dwarfing rootstock M26 were equall...

Captures of male dogwood borer, Synanthedon scitula (Harris), in traps baited with trinary andbinaryblendsof the female sexpheromonecomponentswere comparedwith those in traps baitedwith themost effective commercially available lure in apple orchards inWestVirginia, Virginia, and North Carolina. Traps baited with the trinary blend [88:6:6 vol:vol:vol (Z,Z)-3,13 octadecadienyl acetate (ODDA):(E,Z...

two species of tachinidae, masicera sphingivora (robineau & desvoidy) and bithia glirina (rondani), were collected from pupae and larvae of hyles euphorbiae (l.) (lep.: sphingidae) and chamaesphecia schizoceriformis kolenati (lep.: sesiidae) respectively. masicera sphingivora belongs to the subfamily exoristinae and has mostly been reared from the larvae of sphingidae, especially the genus hyle...

Gas chromatography and mass spectrometry analyses of crude sex pheromone gland extracts revealed that virgin Synanthedon tipuliformis (Clerck), currant borer (Lepidoptera: Sesiidae) females, produced 6 compounds, structurally related to sex pheromone components of clearwing moths. By comparison of retention times and mass spectra of natural products with corresponding properties of synthetic st...
