Hypothesis

How does the survival of larval Naupactus cervinus vary on different groundcover species in New Zealand kiwifruit orchards?

Conclusion

The study found that larval survival of Naupactus cervinus is generally low, but higher on white clover compared to ryegrass.

Supporting Evidence

  • Survival rates of larvae were significantly lower on ryegrass compared to white clover.
  • Larval survival was generally low, ranging from 4% to 11%.
  • White clover provided a more favorable environment for larval development than ryegrass.

Takeaway

This study looked at how well baby weevils survive on different plants in kiwifruit orchards, finding that they do better on clover than on grass.

Methodology

The survival of larval N. cervinus was estimated in field plots and potted plants with varying densities and types of groundcover.

Potential Biases

Potential bias from the limited number of host plants tested and environmental conditions.

Limitations

The study's findings may not be generalizable due to the specific conditions of the Bay of Plenty region.
