Biological control in a changing climate: plant-mediated impact of elevated CO2 concentration on Lobesia botrana eggs and egg parasitism by Trichogramma cacoeciae

Ochratoxin A Management in Vineyards by Lobesia botrana Biocontrol

Grape berries attacked by Lobesia botrana larvae are more easily infected by Aspergillus section Nigri (black aspergilli) ochratoxigenic species. Two-year field trials were carried out in Apulia (Italy) to evaluate a bioinsecticide control strategy against L. botrana and the indirect effect on reducing ochratoxin A (OTA) contamination in vineyards. A commercial Bacillus thuringiensis formulate...

Effects of Intra- and Interpatch Host Density on Egg Parasitism by Three Species of Trichogramma

Host-foraging responses to different intra- and interpatch densities were used to assess three Trichogramma spp. (Hymenoptera: Trichogrammatidae) Trichogramma deion Pinto and Oatman, T. ostriniae Pang and Chen, and T. pretiosum Riley - as potential biological control agents for the Indian meal moth, Plodia interpunctella Hübner (Lepidoptera: Pyralidae). Single naïve females were allowed 6 h to ...

The impact of global elevated CO2 concentration on photosynthesis and plant productivity

CURRENT SCIENCE, VOL. 99, NO. 1, 10 JULY 2010 46 This is the fourth article on the theme ‘Photosynthesis and the Global Issues’ being guest-edited by Govindjee, George C. Papageorgiou and Baishnab C. Tripathy. The first article by Lars Olof Björn and Govindjee discussed the evolution of photosynthesis and the chloroplasts and was published in 2009 (vol. 96, pp. 1466–1474); the second article, b...

Effects of fine-grain habitat complexity on egg parasitism by three species of Trichogramma

Effects of microhabitat complexity on host foraging by three species of Trichogramma (T. deion, T. ostriniae, and T. pretiosum) were evaluated under simulated stored product conditions. All three species have been considered as potential biological control agents for the Indianmeal moth, Plodia interpunctella, in retail stores and warehouses. Trials were conducted with single naı̈ve female paras...
