Female life span is about three weeks.
It has molts, 6 instars. 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 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.
Adult sawflies do not easy bleed but have glucosinolates carried over from the larval stage.
Views Read Edit View history. Then copulation and oviposition take place. This page was last edited on 15 Novemberat Athalka body of larva is wrinkled, covered with small warts.
Turnip sawfly – Wikipedia
The turnip sawfly, Athalia rosae Linnaeus, is a pest on cruciferous crops. Athalia rosae Linnaeus This is to ensure that we give you the best experience possible. Adult larva penetrates into the ground for pupation.
Abdomen is thick, pointed in female, rounded in male. The head has a black athala clavate apically antenna.
Retrieved from ” https: 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, Go to distribution map These results indicated the possibility of using a similar method of control in commercial fields.
The pest eats leaf mass, buds, flowers, young pods. Oligophagous pest of cruciferous zthalia umbelliferous cultures. Several of the sawfly larvae were rejected after an initial attack, demonstrating unpalatability to the lizards, while the Pieris larvae were not rejected. The strongest harming activity is marked on turnip. In other projects Wikimedia Commons. Tenthredinidae Insects described atahlia Pests and diseases of fodder cultures.
Face and anterior of head with setae; thorax with protuberances developed weakly, one rosse 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, Movement and colour may be important additional factors triggering the behaviour of vertebrate predators.
The results suggest that for the defensive effectiveness of the pest sawfly species against vertebrates the chemical cue is not necessarily sufficient. Biological Control Laboratory and field experiments performed 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.
Pests Athalia rosae L. The species gives generations athaliaa a year; i. 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, This has been shown to be an effective, chemical-based, defence against invertebrate predators.
The efficiency of this proposed defence was tested against a vertebrate predator, using groups of the iguanid lizard Anolis carolinensis Voigt as a model predator.
