Red-belted clearwing moth, Synanthedon myopaeformis

Synanthedon myopaeformis is a native of North Africa and Europe that has recently invaded North America. The red-belted clearwing is a destructive insect pest of top and stone fruit crops, most notably apples, pears, plums, quinces, cherries and apricots. Females lay up to 250 eggs within the bark of fruit trees and upon hatching, larvae feed on plant tissues beneath the bark which can lead to tree death. Severe infestations can build quickly and cause massive reductions in crop yield and treee death. Use Mothcatcher and Delta traps with species-specific pheromone lures for monitoring in order to time treatments as part of an effective integrated pest management programme.

Monitoring
Application Guidelines

Lures
Lures can be changed every 4-6 weeks to get the most accurate results.

Lures Handling
Pheromone lures are a very sensitive tool. They can be affected by exposure to elevated heat and direct sunshine. Direct touching by hand may cause cross contamination leading to mixed catches in the trap. Some contaminants such as Nicotine May have repellent effect reducing trap catch.

Lure Storage
Store in a cool dry place. Shelf life can vary from 3-36 months depending on the storage temperature. See Technical Data Sheet for further details.

Trap Selection

The Deltra trap is the most sensitive trap to use for monitoring this insect. However, Moth catcher may be used in dusty conditions or in high moth population density.

Trap Density

Do not re-use the trap to monitor different insects as this may lead to mixed catches. One trap for every two hectares of large scale fields of homogenous lands.

Two traps per hectare (2trap/ha) for small holdings and in field of uneven topography.

Trap Position

Place traps near the highest point of the plant using supporting posts approximately 1 meter high, or higher if the crop is higher.

Data and Interpretation

Collect data weekly from the start of the flight of the over wintering generation. During the height of the population more frequent reading may be needed. Decisions on pesticide application should not be taken solely on the trap catch data. Climatic and biological considerations should be taken in account.
