15 صفحه اولEvaluation of Partial Plant Sampling Procedures and Corresponding Action Thresholds for Management of Lepidoptera on Cabbage
J. Econ. Entomol. 78: 913-916 (1985) ABSTRACT Within-plant sampling procedures, coupled with action thresholds for cabbage-feeding caterpillars, were evaluated for accuracy and efficiency in New York,Ontario, Canada, and Wisconsin in 1982. When results were averaged over the three sites, use of all thresholds required fewer insecticide applications than a fortnightly schedule, while the total p...
متن کاملEffect of Beauveria bassiana (Hypocreales: Clavicipitaceae) and Fungicide Applications on Megacopta cribraria (Hemiptera: Plataspidae) in Soybean
Declining populations of kudzu bug, Megacopta cribraria (F.), in the southeastern United States have been observed since 2013 and are generally attributed to increased prevalence of natural enemies. Beauveria bassiana (Bals.-Criv.) Vuill. infects kudzu bugs in North America, but the level of pest suppression has not been reported. Beauveria bassiana is sensitive to classes of fungicides used to...
متن کاملDistribution Free Confidence Intervals for Quantiles Based on Extreme Order Statistics in a Multi-Sampling Plan
Extended Abstract. Let Xi1 ,..., Xini ,i=1,2,3,....,k be independent random samples from distribution $F^{alpha_i}$، i=1,...,k, where F is an absolutely continuous distribution function and $alpha_i>0$ Also, suppose that these samples are independent. Let Mi,ni and M'i,ni respectively, denote the maximum and minimum of the ith sa...
متن کاملAction Change Detection in Video Based on HOG
Background and Objectives: Action recognition, as the processes of labeling an unknown action of a query video, is a challenging problem, due to the event complexity, variations in imaging conditions, and intra- and inter-individual action-variability. A number of solutions proposed to solve action recognition problem. Many of these frameworks suppose that each video sequence includes only one ...
