In Hawaii, the introduction of natural enemies for the biological control of insect pests continues to be the method chiefly employed. During the period 1920-1925 inclusive, the important successful introductions were as follows:

1920―Cyrtorhinus mundulus, a mirid bug from Australia and Fiji which feeds on the eggs of the sugar cane leaf-hopper and has now brought that pest under complete control.

1921―Four bruchid parasites from Texas.

1921―Ischiogonus syagrii, a parasite of the Australian fern weevil, introduced from Australia and has checked the spread of this fern weevil in the native forests.

1921-1922―Pleistodontes froggatti and Pleistodontes imperialis, caprifiers of Ficus Macrophylla and Ficus rubiginosa, two Australian trees being used in reforesting projects in Hawaii.

1922―Pseudaphycus utilis from Mexico, as a parasite on-the avocado mealybug, (Pseudococcus nipae) which it has now practically eliminated.

1923―Lysiphlebus testaceiPes from California. An aphid parasite which has already become established and reared from four different aphids.

1923-1924―Euplectrus platyhypenae and Archytas cirphiae from Mexico as parasites of Armyworms. Already established and widely spread.

1925―Anagyrus dactylopii from Hong Kong as parasite of Pseudococcus filamentosus. Already established in several localities and promising well.
