Russell IPM manufactures and supplies pheromone lures, traps and complete monitoring systems for Archips podana, fruit tree tortrix moth.
Pheromone trap data gives early warning of the infestation and also exhibits the density of the insect population.
Pheromone application guidelines
The following notes are guidelines of general nature and meant to give the user a head start in implementing pheromone monitoring programme. Local conditions and practices can vary and can lead to customisation of the programme
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.
Do not re-use the trap to monitor different insects as this may lead to mixed catches.
Trap density
Two traps per hectare (2trap/ha) for small holdings and in field of uneven topography.
One trap for every two hectares of large scale fields of homogenous lands.
Trap position
Place trap near the highest point of the plant using supporting posts approximately 1 meter high, or higher if the crop is higher.
Trap data and interpretation
Collect data weekly from the start of the flight of the over wintering generation.. During the height of the population a 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.
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.
