ResumoThe life history of the Apple-Blossom Weevil, Anthcmomus pomo-rum, a serious pest in apple-growing districts, has been worked out and is herein described. The adult, of which a full description, including that of the alimentary and genital systems, is given, spends the winter hibernating in or near apple orchards. In spring the adults leave their winter quarters and, prior to mating, feed by piercing the fruit buds and sucking the juices. Egg laying is performed when the development of the buds is in the stage known as “Cluster-bud.” The egg is thrust into the centre or the young flower by the ovipositor of the female. The stages, oval, larval, and pupal are described followed by a discussion of the habits of the young adult which is shown to feed on the under surfaces of the leaves. Natural enemies, including birds, insects and fungi, are shown to play an important part in limiting the extent and distribution of the weevil.
