PEAR MIDGE.

A DREADED PEST. NELSON, Feb. 6. A few months ago it was reported that the pear midge,' one of the most dreaded of orchard pests, bad been discovered in an orchard at Tasman. The discovery, it was stated, had then been confined to one orchard, and prompt and energetic measures were taken to cope with it and prevent its spread. Now the midge has been discovered over a wide area in Motueka and Riwaka, and in old pear plantations. Spraying is stated to be ineffective for dealing with the pest, as it is so difficult to get at, and the hope of the orchardist lies in the introduction of a parasite. Even if this can be done, it must take , a considerable time, and tbe prospects are that in the meantime the pear-growing industry will receive a very serious check. , From time to time parasites for tree pests have been introduced into Nelson, with successful results, and something may yet be done to prevent the pear industry being wiped out. One of the difficulties facing a new country like New Zealand is that the pests, being imported, often get a big start, and work much havoc before a parasite eari be introduced. In older countries an equilibruim is established between pest and parasite, and in tbe days to come similar conditions may prevail in the Dominion.
