Effect of Beauveria bassiana (Balsamo) Vuillemin (Ascomycota: Hypocreales) on Diadegma semiclausum (Hellen) (Hymenoptera: Ichneumonidae), a parasitoid of Plutella xylostella (L.) (Lepidoptera: Yponomeutidae)
Investigation of the interactions among Plutella xylostella (host), Beauveria bassiana (pathogen) and Diadegma semiclausum (parasitoid) was the aim of this thesis. The pathogenicity of B. bassiana to P. xylostella larvae and D. semiclausum females, the direct and indirect effect of the pathogen on …

Interrelationship of Bacillus thuringiensis Berliner to diamondback moth, Plutella xylostella L. (Lepidoptera: Plutellidaae), and its primary parasitoid, Diadegma insulare Cress (Hymenoptera: Ichneumonidae)
… Diadegma insulare Cress (Hymenoptera. Ichneumonidae), was studied by determining: the differential response of third instar diamondback moth, parasitized and unparasitized, to B. thuringiensis, and the ability of D. insulare to discriminate between B. thuringiensis-treated and untreated …

The role of foliar glucosinolates in host plant resistance of oilseed rape and mustard to the Bertha armyworm and the diamondback moth
… rates by Diadegma insularis (Hymenoptera: Ichneumonidae) were not significantly different between plant species on foliar samples. On flower head samples, larvae on B. juncea were parasitised the most, whereas larvae on S. alba were parasitised the least. The glucosinolate profile of the …

Evaluation of the potential of Pteromalus puparum (L.) (Hymenoptera: Pteromalidae) for suppression of the imported cabbageworm and parasitism of the diamondback moth
… <i>Diadegma insularis</i> (Meus.) (Hymenoptera: Ichneumonidae) parasitized 46% and 69% of the diamondback moth in 1983 and 1984, respectively. Higher parasitization of <i>P. xylostella</i> was found in pupae collected from Abbott & Cobb #5. Two generations of the cabbage looper were seen in 1983 …
