Extract

1. Insect pests of the blackberry (Rubus fruticosus, L.) are being studied with a view to discovering insects likely to assist in the biological control of this noxious plant in New Zealand. Habrosyne derasa, L., was the first species brought under observation.

2. Investigations revealed an apparently unique method of oviposition, the eggs of H. derasa being deposited on the points of the serrated leaf-edges of the blackberry.

3. Newly hatched larvae of this moth have been simultaneously tested as to their ability to feed and thrive on the following plants:—Blackberry (normal host), loganberry, raspberry, rose, apple, cherry, plum, pear, and currant. They thrived equally well on the first three plants. Ten-day-old, blackberry-fed larvae, when transferred to rose and apple, fed and some ultimately pupated. Similar larvae transferred to cherry, plum and pear fed sparingly but did not succeed in pupating.

4. When a choice of food-plants was given, feeding was concentrated on blackberry, loganberry and raspberry.
