Horse Chestnut Leaf Miner Pheromone Dispenser Trial

Background

Cameraria Damage Full Tree ImageThe Horse chestnut leafminer, Cameraria Ohridella, is a pest of Horse Chestnut trees across Europe. Since 1985, Cameraria Ohridella has rapidly spread across Europe, first arriving in the UK in 2002. The larvae of this moth pest are leaf miners, feeding on the inner tissues (parenchyma) of leaves, protected between the outer layers of epidermis and cuticle. Larval feeding creates semi-translucent and brown circular areas on the leaf and large populations rapidly transform a healthy green horse chestnut tree into a brown, unhealthy and unsightly looking version.

Approach to Monitoring and Controlling

One method of monitoring for and controlling this pest is the use of a pheromone trapping system. The sex pheromone, produced by female moths to attract males, is adsorbed onto a dispenser and the dispenser placed in a trap containing a sticky glue board. Male moths attracted to the pheromone dispenser become entangled in the glue and are unable to escape.

Currently, the standard dispenser used does not persist for long enough in the field so attraction of male moths has been reported to decline after ca. two to three weeks. Ideally, attraction should persist for four weeks atleast before the dispenser needs replacing. Here at International Pheromone Systems, we are hoping to address this issue by running a trial over a five week period to investigate the performance of three different dispensers and the effect of adding an extender to the pheromone formulation.

We will post photos on a weekly basis to visually show how the various dispensers are performing and the hope is that we will be able to identify a superior pheromone dispensing system for the Horse Chestnut Leaf Miner - Cameraria Ohridella.

Halyomorpha halys or Brown Marmorated Stink Bug

The brown marmorated stink bug, Halymorpha halys is an insect pest that has recently been attracting a lot of interest from both researchers and concerned farmers. Much of this interest has been in North America but as this pest is now beginning to spread through Europe, there is going to be a greater demand for information on this pest and suitable products for its control. Below, we give a brief summary of this pest, why there is a growing concern and what options there are for farmers to safeguard their crops.


Identifying Halymorpha halys

H halys idLike all shield or stink bugs adult H. halys are shield shaped with a long piercing-sucking rostrum or mouth part which is tucked underneath the body when not feeding. The common name of "brown marmorated stink bug" stems from the marble like pattern present on the head, pronotum and legs. The four most important features to look out for are:
