Sirex wasp (1 o 2)

Sirex wasp

The sirex wasp (Sirex noctilio) is an introduced pest that lays its eggs in pine trees, fatally weakening them. Its effects were understood in the early 1900s, and biological control methods were trialled successfully in the 1930s. However, it wreaked havoc in the Kāingaroa State Forest in 1945 and 1946.
