Natural green lacewing solution for aphid and mealy bug management
Chrysoline is a biological control agent containing second instar larvae of Chrysoperla species, commonly known as Green Lacewings. These larvae are generalist predators that feed on insects, mites, and aphids. Adult lacewings feed only on nectar and pollen, and do not prey on pests, making them harmless once mature.
Benefits of Chrysoline :
- ✅ Broad pest targeting: Suitable for a wide range of aphid species on different crops, helping with effective use even when pest species identification is challenging.
- ✅ High consumption rates: A single larva can consume significant numbers of aphids during its development, with studies showing over 200 aphids in 14 days at 21 °C.
- ✅ Easy monitoring: Larvae are visible on plants, making observation and tracking straightforward.
- ✅ Lifecycle detail: Adult females lay single eggs on long stalks, usually on the underside of leaves; larvae hatch and move down these stalks to begin searching for prey immediately.
- ✅ Localised application: Well suited for hotspot treatments where aphid colonies are established, as larvae require live prey to complete development and are not suitable for preventive use.

How it works
Chrysoline larvae remain on aphid colonies, acting as a curative treatment for localised infestations. They use their mandibles to pierce prey and inject enzymes that gradually digest internal tissues. Once digestion is complete, the liquid contents are consumed. Adults naturally disperse, so repeat releases may be needed to maintain ongoing management. Tests have shown a single larva can consume:
> More than 200 Macrosiphum euphorbiae in 14 days at 21 °C
> 385 Myzus persicae in 14 days at 21 °C
> 425 Aphis gossypii in 14 days at 21 °C
