Insect behavior and control techniques

The European pine sawfly, Neodiprion sertifer (Geoffr.), is a serious defoliator of pine in many parts of Europe and Asia. Infestations of this insect have been controlled by weather, and frequently high percentages are destroyed by parasitic and predacinus insects, by small mammals, and by birds. Infectious diseases are most frequently reported as having controlled outbreaks, namely: virus disease (4, 5), bacterial disease (12). fungus disease (8), bacterial and fungus diseases (7, 11), a disease not diagnosed (9).
