OPTIONAL PLANS OF BINOMIAL SEQUENTIAL CLASSIFICATION SAMPLING FOR MANAGEMENT DECISION MAKING OF THE ENGLISH GRAIN APHID (HOMOPTERA: APHIDIDAE):VALUE OF TALLY THRESHOLDS OF APHIDS IN SAMPLE UNITS

Feng Mingguang(Department of Biological Sciences and Technology, Zhejiang Agricultural University,Hangzhou, China, 310006)  
Binomial sequential classification sampling plans were developed for use in classifying populations of the English grain aphid, Sitobion avenae, below or above an intervention threshold density(mIT) for management decision making. Based on field data from sampling the aphid populations on wheat during the 1988~1991 summers, the proportion of tillers with no more than T(tally threshold) aphids(pT) was related to mean aphid density(m)with an empirical model in the form of ln[ -ln (PT)] = a+bln(m)or the negative binomial distribution (NBD) model. Three mean intervention threshold(mIT) values(2, 6,and 10 aphids per tiller) with T values ranging from 0 to 25 were used to meet the needs for control of the aphid pest varying in density at the flowering,milky and mid-dough stages, respectively. The sampling plans were evaluated using operating characteristic(OC) and average sample number (ASN) functions computed using the empirical PT-m model or the NBD model. The robustness of the sampling plans improved with increasing T values. When empty tiller(T= 0)was used to classify sample units, the resulting sampling plans were not robust for all mIT values con- sidered. This indicated a high risk for use of conventional binomial sampling plans. Based on the OC and ASN functions,the sampling plans recommended for use were those developed with T values slightly higher than the intervention thresholds at the corresponding crop stages.Sampling stop lines for each mIT and T were provided along with a discussion of their applica-tion to aphid sampling and management decision making.
