Assays were conducted to assess the number of Beauveria bassiana (Bals) Vuill. conidia on Diatraea saccharalis F. (Lepidoptera: Pyralidae), Nezera viridula (L.) and Piezodorus guildinii (Westwood) (Hemiptera: Pantatormidae) corpses maintained at different levels of relative humidity (RH) (75%, 80%, 90% and 100%) and temperatures (22oC, 26oC, 30oC and 34oC) during five days. The isolates produced conidia when exposed to RH from 75% to 100%. Conidiogenesis was incipient at 75% RH on D.saccharalis larvae, but did not occur on N. viridula and P. guildinii. In ideal conditions od RH and during 10 days, mathematical equations were developed to estimate the number of condia produced by isolates ARSEF 933 and ARSEF 2515. Conidia number were shown to be dependant on RH, temperature, fungal isolate, host species, host stage, and time. |

A literature analysis of 158 papers published in international peer-reviewed journals indexed by the Thomson Reuters Web of Knowledge from 1994 to 2013 showed that CO2C emission was significantly lower in free water surface (FWS) constructed wetlands (CW) than in subsurface flow (SF) CWs (median values from 95.8 to 137.0 mg m−2h−1, respectively). In vertical subsurface flow (VSSF) CWs the CH4Cemission was significantly lower than in horizontal subsurface flow (HSSF) CWs (median values 3.0, 6.4,and 4.0 mg m−2h−1, respectively). There were no significant differences in N2O N emission in various Cw types (median for FWS, VSSF and HSSF CWs: 0.09, 0.12, and 0.13 mg m−2h−1correspondingly).The highest value of emission factor (EF) of CH4((CH4C/inflow TOCin) * 100%) was found for FWSCWs (median 18.0%), followed by HSSF CWs (3.8%), and VSSF CWs (1.28%). Median values of N2O EFs((N2O N/inflow TNin) * 100%) differed significantly in all three CW types: 0.34% for HSSF, 0.11% for FWS,and 0.018% for VSSF CWs.We found a significant correlation between TOCin and CH4C emission and between the TNinandN2O N emission values for all of the types of CWs we studied.Hybrid CWs (e.g., the subsequent combination of VSSF, HSSF and FWS CWs) are beneficial from thepoint of view of both water purification and minimization of greenhouse gas (GHG) emissions. Likewise,intermittent loading in VSSF CWs and macrophyte harvesting in HSSF and FWS CWs can mitigate GH Gemissions. |
