Coleobug contains larvae of Coleomegilla maculata, commonly known as the Pink Spotted Lady Beetle. Native to North America, this versatile predator is highly effective against aphids and can also contribute to mealybug suppression.

Unlike many predators that depend entirely on prey, C. maculata can survive on pollen and nectar when pest populations are low. This allows it to remain active in the crop longer and respond quickly when pest populations begin to increase. Its high reproductive potential, adaptability, and voracious appetite make it an excellent tool for curative aphid control programs.

Here’s What They Look Like at Different Stages of Their Life

• Eggs: Eggs are pale yellow and spindle-shaped. Females lay clusters of 10–40 eggs near aphid colonies to ensure newly emerged larvae have immediate access to food.
• Larvae: Larvae are dark gray to black with orange or pink markings. They have an elongated, alligator-like appearance and are the most voracious life stage. Larvae actively search foliage for prey and can consume more than 30 aphids per day under optimal conditions.
• Pupae: The pupa attaches to a leaf or plant surface and ranges in colour from yellow-orange to deep orange with darker markings. During this stage, the insect transforms into an adult beetle.
• Adults: Adults measure approximately 4–7 mm long and are easily recognized by their bright pink to reddish-pink colour with black spots on their wing covers. Adults continue feeding on aphids while also consuming pollen and nectar.

Because all stages (especially larvae and adults) are mobile and feed on aphids, you should actively notice them moving through the crop as they search for prey.

Why Growers Love It

• Both larvae and adults consume large numbers of aphids.
• Integrates smoothly with other biological controls and cultural measures.
• Simple distribution and rapid establishment when aphids are present.
• Safe for people, plants, beneficial insects, and the environment.
• Native North American species.

Timing is critical to achieving success with predatory beetles. They perform best when introduced pests have reached outbreak levels.

Preventive Use:

• Coleobug is primarily recommended as a curative biological control agent.
• However, preventative introductions can be beneficial in crops with a history of recurring aphid or mealybug pressure.
• Introduce lady beetles when you start seeing aphids or mealybugs.

Curative Use:

• Deploy during times of high aphid or mealybug infestations.
• Multiple releases will be required if pest pressure is high or crop is mature and dense.

Environmental Conditions:

• Most effective between 15 and 33°C (59 and 86°F). Activity slows at lower temperatures (< 14 °C).
• Adult ladybirds are good fliers and can disperse over a large area in search of prey.
• Avoid areas where recent broad‑spectrum insecticides were applied, such treatments may reduce performance of the predator.

Note: Monitoring is essential. Inspect leaves and stems, and any other plant crevices weekly to determine if additional releases are required.

Proper release techniques ensure the Coleomegilla maculata establish quickly and begin controlling pests effectively:

1. Distribute the product: Carefully open the cardboard cylinder and release beetles near infested or high-risk areas.
2. Recommended density: Introduce based on pest pressure. Often 5–40 larvae per m² per release, repeated at intervals until control is achieved.
3. Follow‑up releases: In curative situations or severe infestations, a second release after 7–14 days often improves establishment and control.
4. Avoid interference: Do not release immediately before or after broad‑spectrum insecticide applications. If treatments are needed, choose only those compatible with beneficial insects.
