ENEMY OF THE APHIS.
ACCLIMATISATION PROBABLE. EGGS FOUND AT CHRISTCHURCH. CHRISTCHURCH, Dec. 28. Experiments conducted by Mr A. Tonnoir, entomologist at the Canterbury Museum, show that the green lace wings introduced to- New Zealand from British Columbia to deal with the green aphis on oaks can be at least acclimatised in New Zealand. Whether or not they will check the aphis will be disclosed when the experiments have advanced a stage. About 600 perfect lace wings sent to Mr Tonnoir by Dr. Tillyard, chief biologist of the Cawthron Institute, Nelson have been held captives in bags tied to infected twigs of oaks in the museum grounds in- North Hagley Park, and in Mr J. R. Montgomery’s garden, Carlton road, Fendalton. In a vivarium at the museum some of the insects have laid many eggs. These are very small, oval and, like the perfect insects, light green. It is on the larvae or grubs that entomologists rely for help in the war against the aphis. The perfect insects are pretty IfTMe creatures. Their lace-like wings are diaphanous. Their greatest beauty, however, is in their eyes, which are golden, a character that has earned for them an appropriate entomological name, chysopa, golden eyes.
