The flea beetle, Phyllotreta nemorum L. (Coleoptera: Chrysomelidae), is an intermediate specialist feeding on a small number of plants within the family Brassicaceae. The most commonly used host plant is Sinapis arvensis L., whereas the species is found more rarely on Cardaria draba (L.) Desv., Barbarea vulgaris R.Br., and cultivated radish ( Raphanus sativus L.). The interaction between flea b...

The frequency of gene flow from Brassica napus L. (canola) to four wild relatives, Brassica rapa L., Raphanus raphanistrum L., Sinapis arvensis L. and Erucastrum gallicum (Willd.) O.E. Schulz, was assessed in greenhouse and/or field experiments, and actual rates measured in commercial fields in Canada. Various marker systems were used to detect hybrid individuals: herbicide resistance traits (H...

Presently, chemical control is the most used method for plant protection. However, it not an approach that environmentally sustainable. Alternative IPM methods include biological such as Allelopathy can be a good alternative in protection.Allelopathy defined direct or indirect interaction, whereby allelochemicals released by one organism influence physiological processes of other neighboring or...

Recently re-named as a sub-species of Mellinus arvensis , Mellinus arvensis obscurus Handlirsch 1888 was investigated ecologically and morphologically in Nepal, in order to underline the most important differences with the well known M. arvensis arvensis . Mellinus arvensis obscurus females nested in clumped aggregations on inclined plains at high altitudes, both on sunny bare soil and on a sha...

Wild mustard (Sinapis arvensis L.) and milk thistle (Silybum marianum (L.) Gaertn.) are two competitive broad-leaved weeds commonly found in cereals Europe, while several weed species have developed resistance to the main herbicides that applied on these crops. Thus, implementation of integrated management (IWM) programs is great importance. Field experiments were conducted based a split-plot d...
