Integrated pest management approach for a new pest, Lacanobia subjuncta (Lepidoptera: Noctuidae), in Washington apple orchards.
Bioassays of Lacanobia subjuncta (Grote and Robinson) larvae established baseline LC50 values and identified the potential of reduced-risk, organophosphate replacement and naturally derived insecticides (eg chloronicotinyls, spinosyns, oxadiazines, insect growth regulators, microbial insecticides and particle films) to control this pest. The toxicities of these products were compared with those...
متن کاملa study on rate making and required reserves determination in reinsurance market: a simulation
reinsurance is widely recognized as an important instrument in the capital management of an insurance company as well as its risk management tool. this thesis is intended to determine premium rates for different types of reinsurance policies. also, given the fact that the reinsurance coverage of every company depends upon its reserves, so different types of reserves and the method of their calc...
Automated Crop Yield Estimation for Apple Orchards
Crop yield estimation is an important task in apple orchard management. The current manual sampling-based yield estimation is time-consuming, labor-intensive and inaccurate. To deal with this challenge, we developed a computer vision-based system for automated, rapid and accurate yield estimation. The system uses a two-camera stereo rig for image acquisition. It works at nighttime with controll...
متن کاملTarget Recognition for the Automatically Targeting Variable Rate Sprayer
In order to quickly and accurately realize target recongnition when the crop demanding, adopt green strength of RGB`s method to identify the crop from the background of elaphic, the recognition accuracy was more than 98%. Use density DBSCAN fuzzy clustering algorithm, by means of setting two parameters ε and MinN, in the density DBSCAN fuzzy clustering algorithm, to determine a cluster gather o...
متن کاملDevelopment of a Variable Rate Chemical Sprayer for Monitoring Diseases and Pests Infestation in Coconut Plantations
An image processing-based variable rate chemical sprayer for disease and pest-infested coconut plantations was designed and evaluated. The manual application of chemicals is considered risky and hazardous to workers, and provides low precision. The designed sprayer consisted of a sprayer frame, motors, a power system, a chemical tank and pump, a crane, a nozzle with a remote monitoring system, ...
