White Grub Control Trial, Ft. Morgan, Co, 1991

Detection of White Grub Damage in Turfgrass Using Remote Sensing

Rationale White grubs (e.g. larvae of Japanese beetles or masked chafers) are the most destructive and economically injurious pests of turfgrasses in the Midwest and eastern United States. Developing grubs feed on turfgrass roots at the soil/thatch interface or in the first few centimeters of soil. Visual evidence of an infestation includes thinning, wilting in the presence of adequate irrigati...

Biocontrol Potential of Entomopathogenic Nematodes Heterorhabditis and Steinernema Against Second Instar Grub of White grub, Leucopholis lepidophora (Blanchard)

The effectiveness of two entomopathogenic nematodes (EPN) viz., Heterorhabditis indica strain NBAII-104 and Steinernema carpocapsae strain NBAII-04 against second instar grubs of L. lepidophora (Blanchard) under pot culture experiment. At a concentration of 450 IJs ml, H. indica recorded highest mortality (87.60%) at 15 DAT. While, S.carpocapsae recorded 54.05 per cent grub mortality at 450 IJs...

Introduction Landsat Thematic Mapper ( TM ) imagery was used to analyze patterns of landscape diversity in the seasonal tropical forests of northeastern Guatemala. TM radiance and the radiance coefficient of variation (CV) were significant in discriminating land-cover types. Cluster analysis of TM4, TM5, and TM7 radiance produced six distinct types of landcover. Green leaf biomass from TM4 and ...

Invasive pneumococcal disease among White Mountain Apache adults, 1991-2005.

BACKGROUND Certain Native American populations have high rates of invasive pneumococcal disease (IPD). We aimed to determine the disease spectrum and risk factors of White Mountain Apache adults (age, >or=18 years) with IPD and the use and effectiveness of pneumococcal polysaccharide vaccine (PPV) in this population. METHODS We conducted active surveillance for IPD between 1991 and 2005. Medi...
