Hall et al.: Citrus Rust Mite & the Negative Binomial 1 CITRUS RUST MITE (ACARI: ERIOPHYIDAE) COUNTS ON FRUIT AND THE NEGATIVE BINOMIAL DISTRIBUTION
Count data for the number of citrus rust mites per cm 2 on fruit across a 4-ha (10acre) area of orange trees followed the negative binomial probability distribution 79% of the time based on chi-square tests. A correlation of r = 0.993 was found between observed counts and counts projected based on the distribution. A common k of 0.149 was computed but generally appeared more suitable for mean d...

متن کاملEffects of reducing sample size on density estimates of citrus rust mite (Acari: Eriophyidae) on citrus fruit: simulated sampling.
The consequence of reducing sample size on the accuracy and precision of estimates of citrus rust mite, Phyllocoptruta oleivora (Ashmead), densities on oranges was investigated. The sample unit was a 1-cm2 surface area on fruit. Sampling plans consisting of 360, 300, 200, 160, 80, 48, 36, or 20 samples per 4 ha were evaluated through computer simulations by using real count data from 32 data se...
