Several plant characters are known to affect the searching behaviour and parasitization efficiency of Trichogramma spp. (Hymenoptera: Trichogrammatidae). In this study, plant characters contributing to the low Helicoverpa armigera (Hübner) (Lepidoptera: Noctuidae) egg parasitism levels on pigeonpea (Cajanus cajan (L.) Millspaugh) were investigated. The efficiency of T. chilonis on pigeonpea was...

Abstract: The objective of this work was to evaluate phytomass production, nutrient cycling, and efficiency use by single intercropped crop systems, in the second crop, under no-tillage. experiment carried out during 2014 2015 Cerrado biome state Mato Grosso, Brazil, a randomized complete block design, with nine treatments four replicates. In 2014, systems were evaluated at 63, 93, 124, 157 day...

This work aims at the modeling of bio-sorption of cadmium(II) onto physically and chemically activated Cajanus cajan (Pigeon pea) husks. Experimental data obtained were fitted to a number of isotherm and kinetic models, and the results interpreted. The monolayer Cd(II) bio-sorption capacities of the husk were found to considerably increase by 2.82 times due to chemical activation, for bio-s...
