Diglyphus-System - fast and efficient leafminer control
How does Diglyphus-System control leafminers?
- Targeted control – Diglyphus isaea parasitises and feeds on leafminer larvae, rapidly reducing pest populations.
- Dual mode of action – both adult parasitoids and their larvae kill leafminer larvae. In addition, female wasps puncture young larvae and feed on them, further reducing the pest population.
- Rapid population build-up – a single female lays 200 to 300 eggs during her lifetime, allowing Diglyphus-System to keep increasing leafminer populations under control.
- Ideal for curative control – Diglyphus isaea prefers late second and third instar leafminer larvae, making it particularly effective once infestations have become established.
- Perfect for IPM programmes – combine Diglyphus-System with Dacnusa-System for comprehensive biological leafminer control throughout the growing season.
When should you introduce Diglyphus-System?
- Start at the first signs of leafminers – introduce Diglyphus-System as soon as the first mines or leafminers are detected.
- Focus on infested areas – release the parasitoids in and around infested zones to achieve rapid control.
- Ideal for increasing pest pressure – thanks to its rapid population development, Diglyphus-System is particularly effective when leafminer populations start to increase.
- Repeat introductions – make three weekly releases to achieve the best results.
How do you release Diglyphus-System?
- Release in the morning or evening – these conditions allow the parasitoids to disperse effectively throughout the crop.
- Allow the wasps to fly out naturally – hold the tube low within the crop so the parasitoids can emerge and begin searching for leafminer larvae.
- Distribute evenly – release the parasitoids in and around infested areas for optimum performance.
- Combine when needed – use Diglyphus-System together with Dacnusa-System for even more effective leafminer control.
Under which conditions should you use Diglyphus-System?
- Active from 15°C (59°F) – Diglyphus isaea remains active at temperatures from 15°C (59°F) onwards.
- Monitor performance in the crop – parasitised leafminer larvae can be recognised by short mines that stop developing early.
- Easy population monitoring – the larvae and pupae of Diglyphus isaea are easy to detect, making it simple to monitor population development.
- Ideal for integrated pest management – combine with other biological control solutions for sustainable leafminer control.
