Field Notes

Description:

The adult feeds on nectar.

Notes:

Turnip Sawfly was found to result in diploid males and females after sister-brother matings. 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 loci. The sawflies have been found to sequester glucosinolates like many insects in larval stages. Removal of various glucosinolates has been shown to reduce sensitivity to host plants in later adult stages.
