The insects that feed on reproductive structures of forest trees are not only economically important, they are fascinating examples of the ability of insects to adapt to and exploit the many niches available in forest ecosystems. Cones, fruits, seeds, nuts, catkins and pollen are rich food sources available to insect herbivores. These reproductive structures are qualitatively and quantitatively different from vegetative parts of the tree, in terms of food quality, spatial and temporal distribution, and plant protective strategies. In this chapter we will explore types of reproductive structure herbivory, nutritive value and host defenses, insect strategies and community structure, evolutionary consequences for the host, and implications for management.

The Mongolian pine borer, Dioryctria mongolicella Wang & Sung (Lepidoptera: Pyralidae), is a major pest in Mongolian pine (Pinus sylvetris L. var. mongolica Litvinov) plantations in the northeast of China. A blend of 11-hexadecenal and 11-hexadecenyl acetate in a ratio of 2:1 was detected from extracts of its female sex pheromone glands by gas chromatography–mass spectrometry. Our field trapping experiments confirmed that the D. mongolicella pheromone consists of a blend of (E)-11-hexadecenal (E11-16:Ald) and (Z)-11hexadecenyl acetate (Z11-16:Ac). The addition of (Z,E)-9,11-tetradecadienyl acetate (Z9E11-14:Ac) and (Z,Z,Z)-3,6,9-tricosatriene (ZZZ3,6,9-23:H) increased catches of male D. mongolicella in sticky traps baited with E11-16:Ald and Z11-16:Ac. However, the addition of (3Z,6Z,9Z,12Z,15Z)-pentacosapentaene or (Z,Z,Z,Z,Z)-3,6,9,12,15-tricosapentaene to lures loaded with E11-16:Ald, Z11-16:Ac, and Z9E11-14:Ac did not significantly increase trap catches of D. mongolicella at two locations in Heilongjiang province, China. The synthetic blend of 400 µg E11-16:Ald, 200 µg Z11-16:Ac, 200 µg Z9E11-14:Ac, and 500 µg ZZZ3,6,9-23:H will help in developing efficient strategies for monitoring and control of D. mongolicella populations in Mongolian pine plantations.
