J. Econ.Entomol.91(3): 624-630 (1998) ABSTRACT Evaluations of the efficacy and persistence of Beauveria bassiana (Balsamo) Vuillemin for control of the diamondback moth, Plutella xylostella (L.),on cnlcifers were done in growth chambers, the greenhouse, and the field. In growth chamber studies done at 21 or 26°C and 60 or 90%RH, neither temperature nor humidity affected the survival oflarvae, b...

The MADS box gene, AGAMOUS-LIKE 20 (AGL20), integrates environmental and endogenous flowering signals in Arabidopsis thaliana. In order to determine if its role is conserved in other plants, we isolated AGL20 orthologs from Brassica campestris, Cardamine flexuosa and Draba nemorosa. The putative amino acid sequences of the orthologs were 94 to 97% identical. We analyzed the flowering phenotype ...

The S-locus-specific glycoprotein of Brassica and the gene encoding it (the SLG gene) are thought to be involved in determining self-incompatibility phenotype in this genus. It has been shown that the Brassica genome contains multiple SLG-related sequences. We report here the cloning and characterization of a Brassica oleracea gene, SLR1, which corresponds to one of these SLG-related sequences....

Brassica napus L. and Sinapis alba L. are two cruciferous species for which some medicinal uses are mentioned in the Iranian, Indian and Chinese traditional medicine. Seed oil of  B. napus has cathartic action, and is either used as such or after partial hydrogenation for cooking, shortening or as margarines. Sees of S. alba have also cathartic action and some other medicinal uses but, beca...

The adults of diamondback moth, Plutella xylostella L, are known to have been transoceanic migrants in Europe since ancient times. The insect, which has its origin in Asia Minor, spread to other parts of the world with the spread of the cultivation of its host, the crucifers, and by using its own migrational abilities over long distances. Several large scale transoceanic migrations have been re...
