The effects of application of an artificial honeydew mixture of glucose, fructose and trehalose (GFT), honey and Bemisia tabaci nymph-extract as kairomonal sources in enhancing the foraging efficiency and performance of Eretmocerus sp. near furuhashii on cucumber plants were studied. Experiments were conducted in small greenhouses (4x3*3 m) using life table methods. Life table data indicated that the total mortality in B. tabaci immature cohorts in all treatments was in the order of fourth instar > first instar > second = third > egg > pupa cohorts. The tested kairomonal materials had a significant effect on the rate of parasitism (p > 0.0415) with 13.23, 9.04 and 10.54% higher than that of control in artificial honeydew of GFT, nymph-extract and honey treatments, respectively. B. tabaci egg/adult survival ratio was also significantly affected (p > 0.0001) by the tested kairomonal sources being lowest (22.91%) in nymph-extract treatment. Moreover, the tested kairomonal materials arrested significantly more parasitoids to colonize the treated plants comparing to control. Apparently, the tested materials were significantly effective in attracting the parasitoids up to 3 days after applications then significant difference was not found between treatments.

Eighteen species are documented from China, including four new species described here: Scymnus (Neopullus) nigroventralis Chen et Ren, S. (N.) brevicollis Chen et Ren, S. (N.) lulangicus Chen et Ren and S. (N.) quercanus Chen et Ren, spp. nov. Diagnoses, detailed descriptions, illustrations and distributions are provided for each species. A key to Chinese species is given.

Corporate environmental information disclosures (EIDs) are important policy tools for environmental protection. This paper assesses and longitudinally examines EID changes in Chinese listed nonferrous metal companies from 2008 to 2012 through their annual, social responsibility, environmental, and sustainability reports. Using content analysis and multivariate regression methods, we fi nd a signifi cant increase in the quantity and quality of corporate EIDs post-2010, though the overall level is still not high. Company size, profi tability, and government regulation signifi cantly and positively affect EID. In addition, we fi nd that state-owned enterprises are more likely to disclose environmental information than private ones.
