Biological control of codling moth
with nemapom (nematodes of the species Steinernema feltiae)
Why use nematodes?
- Steinernema spp. is a natural antagonist of Codling Moth larvae
- Nematodes can reduce overwintering larvae
- Fewer larvae in spring will lead to less infection and better effect of
- CpGV like Madex
- Mating disruption
- Ovicides and larvicides
- No resistance development against nematodes possible
Trial Results 2002 - 2006:
- Katz Biotech, e-nema & Ellen Elias in 4 orchards in Germany and Holland
- Giovanna Curto in pear plantations in Emilia Romagna
- Jutta Kienzle in apple orchards in Southern Germany
- Other investigators in USA, Italy, France and Germany
→ Over wintering larvae can be reduced by 70-90 %
→ Egg deposition in spring can be reduced by 50-70 %
For good results high humidity after application is essential!

Important:
Nematodes are bigger than you think
→ remove all filters and sieves
Nematodes are living animals
→ best to apply soon after reception. If necessary store at 2°- 8°C.
Nematodes dry out quickly
→ spray in dull conditions or late afternoons
Nematodes sink down in water
→ Circulate suspension constantly during application
Steinernema feltiae - nematodes
are
0.9 mm long and 0,025 mm wide
