Detection of White Grub Damage in Turfgrass Using Remote Sensing
نویسندگان
چکیده
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 irrigation, and yellowing or browning of the grass. Grub infestations typically occur in sporadic patches affecting only a relatively small fraction of the turfgrass in an area. The patchy nature of white grub infestations is rarely taken into account when managing these pests because of the difficulty of pinpointing the location and extent of infestation using traditional sampling techniques.

Acoustic estimation of infestations and population densities of white grubs (Coleoptera: Scarabaeidae) in turfgrass.
Incidental sounds produced by Phyllophaga crinita (Burmeister) and Cyclocephala lurida (Bland) (Coleoptera: Scarabaeidae) white grubs were monitored with single- and multiple-sensor acoustic detection systems in turf fields and golf course fairways in Texas. The maximum detection range of an individual acoustic sensor was measured in a greenhouse as approximately the area enclosed in a 26.5-cm-...

Third instar growth and survival, and the effect of larval density of the Japanese beetle, Popillia japonica Newman and the southern masked chafer, Cyclocephala lurida (Olivier) were evaluated on Tifway bermudagrass, Cynodon dactyl on (L.) and KY-31 tall fescue, Festuca arundinacea Schreb. in a threeyear field study. Winter survival was sometimes enhanced in bermudagrass plots. Larval weight ga...
متن کاملLand cover land use mapping and change detection analysis using geographic information system and remote sensing
Land cover/land use categories are relevant components in land management. Understanding how land cover/land use change over time is necessary to assess the consequences of humans and natural stressors on the earth’s environment and resources. The aim of the study was to map and monitor the spatial and temporal change in land cover/land use for the periods of 1977, 1991 and 2016 and to predict ...
متن کاملLow Cost UAV-based Remote Sensing for Autonomous Wildlife Monitoring
In recent years, developments in unmanned aerial vehicles, lightweight on-board computers, and low-cost thermal imaging sensors offer a new opportunity for wildlife monitoring. In contrast with traditional methods now surveying endangered species to obtain population and location has become more cost-effective and least time-consuming. In this paper, a low-cost UAV-based remote sensing platform...
