Population regulation of the Eurasian pine adelgid (Homoptera: Adelgidae) in Hawaii

Population dynamics of the Eurasian pine adelgid, Pineus pini (Macquart), and its predator, Leucopis obscura Haliday, were studied over a 2-yr period in Hawaii. Densities of both species tended to be lowest during the summer dry season and highest at times of increased rainfall and tree flowering in...

Summary:Population dynamics of the Eurasian pine adelgid, Pineus pini (Macquart), and its predator, Leucopis obscura Haliday, were studied over a 2-yr period in Hawaii. Densities of both species tended to be lowest during the summer dry season and highest at times of increased rainfall and tree flowering in winter. Correlation analysis of predator and adelgid densities indicated that the P. pini population was regulated by L. obscura at its higher densities, below economically significant levels.
