Light brown apple moth, Epiphyas postvittana

The light brown apple moth has a wide host range of over 120 fruit, vegetable and ornamental plant species. Host plants include apple, pear, plum, strawberry, grape, potato and privet. They occur in Europe, North America and Oceania. The number of generations per year ranges from two to five according to temperature and host pant. Larvae feed on the surface layer of leaves under a protective layer of spun silk and leaves can be webbed together. Larvae also feed in fruits causing lesions and pitting, which causes economic damage. Monitor adults weekly from petal fall to the end of August using Mothcatcher or Delta traps with species-specific pheromone lures. The economic threshold for treatment is >30 moths per trap per week.

Nature of Damage


Application Guidelines

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.
