Trapping system

The Yellow Bucket Funnel Trap is used in the capturing of the African bollworm moth (Helicoverpa armigera). The Yellow Bucket Funnel Trap consists of four (4) main parts (dome lid, funnel, bucket and white plastic lure cage), which slide into each other. The trap comes with a trap hanger that can attach to the dome lid and be used to hang the trap on a pole, trap stand or tree. The semiochemical lure is placed inside the white plastic lure cage in the top of the dome lid. A dichlorvos block is placed in the bottom bucket of the trap, which kills all insects entering the trap.

A.B.W. PheroLure®

The rubber septa used to attract the African bollworm moth that goes into the trap is known as the A.B.W. PheroLure®. The A.B.W. PheroLure® needs to be replaced every six (6) weeks. Any extra A.B.W. PheroLures® should be kept in their individual foil pouches in a fridge in order to prolong their shelf life before use.

How, where and when to hang traps

  • How: Always hang the trap 30cm above the crop canopy. This will allow for maximum airflow, to distribute the semiochemical molecules (which are heavier than air), across the field/orchard. Place the trap out of the way of farm implements, and  the direct reach of spray machines and irrigation systems. Secure the trap firmly to the pole/stand/tree so that it does not sway in the wind. Identify each trap by a trap/block number for later reference.
  • Where: A map layout of the field/orchard will assist in correct placement of traps. In fields/orchards that are uniform with respect to topography, size and windbreaks, hang traps at a density of 1 trap per 10 – 20 ha for field crops and 1 trap per 2 – 5 ha in orchards. This is the maximum area that can be monitored by a single trap. A higher density may be necessary in unevenly shaped fields/orchards, or fields/orchards with excessive slopes or hollows where the prevailing wind may adversely affect trap catches.
  • When: Tree crops: at beginning of production season.

Field crops: one week after germination or transplanting date.

Inspection and maintenance of traps

  • Inspection: The traps should be inspected weekly on the same day of each week (7-day intervals). The number of African bollworm moths caught in the trap bottom, together with the trap number & date needs to be recorded.
  • Maintenance: The bucket trap needs to be cleaned on a regular basis even if no moths have been caught. The trap bucket tends to get clogged with dust, by-catch and other foreign matter over time.
