Cabbage Looper Moth

Trichoplusia ni, Cabbage Looper Moth

The cabbage looper, Trichoplusia ni, is a serious insect of crop plants in the crucifer family eg. cabbage, cauliflower. broccoli, broccoli, white cabbage and other cabbages. The cabbage looper is an American insect species distributed throughout North America and Europe.

Russell IPM manufacture and supply pheromone lures, traps and complete monitoring systems for cabbage moth Trichoplusia ni. Pheromone trap data gives early warning of the infestation and also exhibits the density of the insect population.


The total life cycle duration ranges from 24-33 days. Adult female lays egg usually singly on the lower leaf surface near the leaf margin. Eggs hatch in 3-4 days. The newly emerged caterpillars are translucent white. Once feeding starts the larvae become pale green, with a thin white line running lengthwise down each side of the body and two white lines along the middle of the back. The caterpillar stage lasts for 12 to 20 days. Pupae are yellow green with a few brown patches when newly formed and gradually darken to dark brown before adult emergence. They are 3/4 inch in length. The pupal stage lasts for 9 days. Adult moths are dark, smoky, gray variegated with light greyish brown. Characteristic small silvery oval spots and U-shaped silvery white marks are on the middle of the forewings. Males have tufts of gold hair at the tip of the abdomen. Adults live for about 24 days and feed on nectars ( Full credited: Ronald F. L. Mau, and J.M. Diez April 2007).

Research & Development

Trap application guidelines

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.

Lures for pest monitoring


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.
