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 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.
Sawfly and moth larvae form one third of the diet of nestling corn buntings (Emberiza calandra), with sawfly larvae being eaten more frequently on cool days. [52] Black grouse (Tetrao tetrix) chicks show a strong preference for sawfly larvae. [53] [54] Sawfly larvae formed 43% of the diet of chestnut-backed chickadees (Poecile rufescens). [48]
Maggot therapy (also known as larval therapy) is a type of biotherapy involving the introduction of live, disinfected maggots (fly larvae) into non-healing skin and soft-tissue wounds of a human or other animal for the purpose of cleaning out the necrotic (dead) tissue within a wound (debridement), and disinfection. There is evidence that ...
Neodiprion lecontei is a species of sawfly in the family Diprionidae native to eastern North America, commonly known as the red-headed pine sawfly or Leconte's sawfly. The larvae feed on the foliage of many species of native and imported pines. This species was named after John Lawrence LeConte, an American entomologist of the 19th century.
Sirex noctilio, known as the European woodwasp, [1] European horntail woodwasp, [2] or sirex woodwasp, [note 1] is a species of horntail, native to Europe, Asia, and northern Africa. [ 3 ] [ 4 ] Adults vary in length from 9 to 36 mm ( 3 ⁄ 8 to 1 + 3 ⁄ 8 in).
Larva (top view) Diprion similis is a species of sawfly in the family Diprionidae. It is native to central and northern Europe and Asia but was accidentally introduced into North America where it has become invasive. The larvae feed on the needles of pine trees, especially those of the white pine (Pinus strobus).
