LONG WAY OFF YET
In response to an inquiry from “The Press.” Dr. J. M. Hoy, director of the Entomology Division of the Department of Scientific and Industrial Research at Nelson, this week corrected the impression that there is an insect available to control sweet briar.
Dr. Hoy said that they had been having a wide range of insects investigated in Europe and there was one insect, a gallwasp, that would warrant investigation in this country, but this could only be done under strict quarantine, and it was hoped that such facilities for testing the insect would be available by the
end of this year or early next year. It was likely that it would be 1967 before it was brought in, he said. A vital aspect of the tests which will be carried out is the possible harmful effect that the parasite could have on plants related to briar. This was a long way from saying that they had an insect that would control sweet briar without any harmful effect on related plants, he said, and if it was proved possible it would probably be several years before this insect could be released.
The gall-wasp attacks the fruit of the briar.
