Pests and diseases of fodder cultures. Turnip sawfly and control treatments. The body of larva is wrinkled, covered with small warts. Turnip sawfly Scientific classification Kingdom: In small-plot tests in Western Siberia, Russia, Indian mustard proved to be the most effective, overall, of a number of crucifers investigated for use as trap crops to protect rape against A. The adult feeds on nectar. During pupation period the ground humidity must be moderate.

Archived from the original on 24 September The results suggest that for the defensive effectiveness of the pest sawfly species against vertebrates the chemical cue is not necessarily sufficient. Face and anterior of head with setae; thorax with protuberances developed weakly, one pair on first and second annulets of prothorax, two pairs on second annulet of meso- and metathorax, three pairs on fourth annulet of meso- and metathorax; abdomen without stout hairs, with two pairs of protuberances on second and third annulets of first segment and two pairs on second and fourth annulets of second to ninth segments Abe, It has molts, 6 instars.

EU pesticides database www. This page was last edited on 15 Novemberat The pest also feeds on wild cruciferous and umbelliferous species, such as Thlaspi arvense L. Dark or green-gray larva mm has black head and 11 pairs of cylindrical legs. The strongest harming activity is marked on turnip.

Some experimental data to ecology of turnip sawfly. These leaves become dry; the plant dies or weakens, not rose yield. Coloration as female except head basal two-thirds of mandibles white, apical one-third of mandibles red-brown; abdomen apical region of first tergum black Benson, ; Abe, The turnip sawfly, Athalia rosae Linnaeus, is a pest on cruciferous crops. Larvae of the first generation are especially dangerous.

Larvae roughly eat leaves, with only big ribs and petiole remaining. Abdominal side is lighter, dorsal side has dark stripes. Movement and colour may be important additional factors triggering the behaviour of vertebrate predators.

Turnip sawfly

Irkutsk plant protection station. The sawfly fecundity varies from to eggs. Lizards attacked far fewer sawfly larvae than pierid caterpillars.

This has been shown to be an effective, chemical-based, defence against invertebrate predators. For further information, we recommend you visit the following resources: Krasnoyarsk plant protection station. Retrieved from ” https: The turnip sawfly and control measures.

Removal of various glucosinolates has been shown to reduce sensitivity to host plants in later adult stages. The fact that glucosinolates being removed causes reduced sensitivity to future possible host plants has been used to argue that these chemicals are important in specific larval patterning to future host plant options. As a consequence of these periods of illumination, females developing from non-diapausing larvae would swarm in autumn at a time when the rape crop was no longer suitable for oviposition Saringer, This differs from normal haplodiploid hymenoptera and after a further cross causing triploid males, resulted in evidence that sex determination is controlled by a single locus.


Large-scale planting of fields with cash-crops such as rape and mustard seed are as equally liable to be infested Rusinov, as greenhouse and small-scale domestic crops of crucifers Nagasaka, The pest eats leaf mass, buds, flowers, young pods. The most important predators are Perilampus italicus Fabr. Several of the sawfly larvae were rejected after an initial attack, demonstrating unpalatability to the lizards, while the Pieris larvae were not rejected. Larvae of the second generation damage in July – August.

Lizards attacked them at a higher rate than larvae and they were never rejected. Pupae Tough, silken cocoon, yellow in colour Hill, Its length is about mm. Oviposition lasts days.

Articles with ‘species’ microformats. Biological Control Laboratory and field experiments rosze in Hungary showed that illumination for 30 minutes during the scotophase in autumn, in the third and eighth hours after the beginning of the dark period, decreased the number of larvae of A. Female cuts leaf by ovipositor and lays eggs inside.

Athalia rosae Linnaeus Turnip sawfly control on mustard sawing. Like most athwlia we use cookies. Note, however, that Lorenz and Kraus consider the abdomen to be devoid of such protuberances.
