The redheaded pine sawfly, European pine sawfly or Neodiprion sertifer, is a sawfly species in the genus Neodiprion. Native to Europe, it was accidentally introduced to North America in 1925, where it has established itself as a commercial pest. [1] The larvae of Exhyalanthrax afer feed on N. sertifer cocoons.
The pine sawfly Diprion pini is a serious pest of forestry. Caterpillar-like larvae of Iris sawfly on yellow flag, showing damage to host plant. Sawflies are major economic pests of forestry. Species in the Diprionidae, such as the pine sawflies, Diprion pini and Neodiprion sertifer, cause serious damage to pines in regions such as Scandinavia.
The larvae feed on pine needles. [3] [4] Eggs are laid in rows in springtime, on pine needles from the previous year. Young caterpillars start feeding on the old needles near where they hatched, leaving the vascular bundles uneaten. Older caterpillars feed more widely, moving to other branches and eating whole needles except for the leaf sheath ...
In Europe, the larvae of Acantholyda erythrocephala are attacked by the parasitoid Tachinid fly Myxexoristops hertingi.In 2002, 2003 and 2004, in an effort to initiate a biological control programme in North America, pupae of this fly were imported from Italy and released in Ontario in an area of red pine (Pinus resinosa) infested with sawfly larvae.
Gilpinia pallida is one of several species known as the pine sawfly. Outbreaks, which can cause considerable damage to pine forests, have been recorded in northern, central, and eastern Europe. Outbreaks, which can cause considerable damage to pine forests, have been recorded in northern, central, and eastern Europe.
Dahlbominus fuscipennis, the sawfly parasitic wasp, is a species of chalcid wasp from the family Eulophidae which parasitizes the European pine sawfly Neodiprion sertifer, among other hosts. It is the only species in the genus Dahlbominus .
Gilpinia video. The Diprionidae are a small family of conifer-feeding sawflies (thus the common name conifer sawflies, though other Symphyta also feed on conifers) restricted to the Northern Hemisphere, with some 140 species in 13 genera.
Two genera and about 15 species occur in Europe. [5] [6] Considering additional fossil records from Australia, [7] South Africa [8] and Argentina, [9] the extant species display a relict distribution. The species in the subfamily Xyelinae are associated with conifers (esp. Pinus and Abies), where the larvae feed on pollen or within buds.
