Turnip sawfly – Wikipedia

Its effectiveness was borne out in a test over ha in which it was sown 7 days before rape in a m band rosaae the crop Vlasenko and Sushkova, Embryonal period varies from 5 to 12 days.

Caterpillars of Pieris rapae Linnaeus and Pieris brassicae Linnaeus served as control prey species that do not sequester glucosinolates.

These leaves become dry; the plant dies or weakens, not giving yield. Removal of various glucosinolates has been shown to reduce sensitivity to host plants in later adult stages.

The larva winters in the ground in a cocoon the depth is about cm. Lizards attacked them at a higher rate than larvae and they were never rejected. Turnip sawfly Scientific classification Kingdom: When attacked, their integument is easily disrupted and a droplet of haemolymph is exuded ‘easy bleeding’.

Note, however, that Lorenz and Kraus consider the abdomen to be devoid of such protuberances. The insect is oligophagous. Views Read Edit View history.

Athalia rosae Linnaeus The fact that glucosinolates being removed causes reduced sensitivity to future rrosae 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.

Retrieved 24 September Lizards attacked far fewer sawfly larvae than pierid caterpillars.

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. Forecasting and calculation of pests and diseases on agricultural cultures. At low damage the leaves resemble a net; at strong damage the sawfly roughly feeds leaf mass, leaving only big ribs and petioles. 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.

Keys to dangerous insects and mites on technical cultures in the USSR. This is to ensure that we give you the best experience possible. The turnip sawfly was found to result in diploid males and females after sister-brother matings. 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, Scutellum and middle lobes of notum, meso- and metathorax are yellow underneath.
