Female sex pheromone of Cameraria ohridella Desch. and Dim. (Lepidoptera: Gracillariidae): structure confirmation, synthesis and biological activity of (8 E ,10 Z )-8,10-tetradecadienal and some

Mass spectrometric investigations confirmed the structure of the female produced sex pheromone of the horse-chestnut leafminer Cameraria ohridella . In mixtures with the synthetic pheromone, analogues like 9-tridec...

COMPARISON OF SPRUCE BARK BEETLE (IPS TYPOGRAPHUS) CATCHES BETWEEN TREATED TRAP LOGS AND PHEROMONE TRAPS

The numbers of Ips typographus beetles captured in treated tripod trap logs (tripods) were compared to catches from Theysohn pheromone traps (TPTs). In 2010 the sex ratio wasbalanced. The TPTs and tripods both ...

Comparison of lure-baited insecticide-treated tripod trap logs and lure-baited traps for control of Ips duplicatus (Coleoptera: Curculionidae)

(Coleoptera: Curculionidae, Scolytinae): lure-baited, insecticide-treated tripod trap logs (TRIPODs) versus Theysohn pheromone traps (TPTs). In 2008 and 2011 and at each of three were trapped by the TPTs than by t...

Monitoring the population dynamics of the horse chestnut leafminer Cameraria ohridella with a synthetic pheromone in Europe.

A monitoring system for Cameraria ohridella males based on a synthetic pheromone was tested in the Czech Republic, France and Greece. We concluded that C. ohridella has typically three generations per year. The pheromone monitoring ...
