Diptilomiopus floridanus (Acari: Eriophyoidea: Diptilomiopidae): Its distribution, relative abundance with other eriophyoid species on dooryard, varietal block, and commercial citrus in Florida
Keywords:
Aceria sheldoni, Aculops pelekassi, Phyllocoptruta oleivora, EriophyidaeAbstract
We sampled 526 dooryard, 18 varietal block, and 784 commercial citrus trees in Florida between May 2009 and April 2014 for eriophyoid mites including: Diptilomiopus floridanus Craemer & Amrine, Aceria sheldoni (Ewing), Aculops pelekassi (Keifer), and Phyllocoptruta oleivora (Ashmead). A total of 1,423 D. floridanus were collected from dooryard citrus trees and one each from “Bearss’ lemon and sweet lime trees from the Florida Citrus Arboretum in Winter Haven. Diptilomiopus floridanus was collected from dooryard citrus in the following counties: Broward, Collier, Dade, Indian River, Lee, Martin, Palm Beach, Pinellas, Polk, Sarasota, and St. Lucie Counties. The mite was not observed in Charlotte, Hardee, Hendry, Highlands, Manatee, or Okeechobee Counties. Percentages of the different eriophyoid mites collected from dooryard citrus trees and varietal blocks were: A. pelekassi 3.2%, A. sheldoni 9.1%, D. floridanus 17.3%, and P. oleivora 84.2%. The six counties with the highest frequencies of D. floridanus on dooryard trees were: Collier 36%, Broward 25%, Indian River 25%, Palm Beach 25%, Martin 23%, and St Lucie 22%. In commercial citrus, A. sheldoni was collected less than 1%, A. pelekassi 4.0%, and P. oleivora 75.5% of the time. Diptilomiopus floridanus was not collected in commercial citrus orchards during this survey. Diptilomiopus floridanus had significantly greater frequencies of occurrence on lime and lemon compared to grapefruit, tangerine, tangelo, sweet orange, and pummelo trees. However, infestation rates on lime and lemon were not significantly different from those on sour orange trees.

Resumen
Se muestrearon 526 árboles de cítricos residenciales, 18 bloques varietales y 784 árboles de cítricos comerciales en la Florida entre el mayo del 2009 hasta el abril del 2014 para los ácaros eriofioides incluyendo Diptilomiopus floridanus Craemer & Amrine, Aceria sheldoni (Ewing), Aculops pelekassi (Keifer) y Phyllocoptruta oleivora. En total, 1.423 individuos de D. floridanus fueron recolectados de árboles de cítricos y 1 cada uno de árboles de limón Bearss y lima dulce del Arboreto de Cítricos de Florida en Winter Haven. Se recolectó Diptilomiopus floridanus en los siguientes condados: Broward, Collier, Dade, Indian River, Lee, Martin, Palm Beach, Pinellas, Polk, Sarasota y St. Lucie. El ácaro no se observó en los condados de Charlotte, Hardee, Hendry, Highlands, Manatee o Okeechobee. Las frecuencias de las especies de ácaros eriofioides recogidas de los árboles cítricos y bloques varietales fueron: A. pelekassi 3,2%, A. sheldoni 9,1%, D. floridanus 17,3% y P. oleivora 84,2%. Los 6 condados con las frecuencias más altas de D. floridanus en los árboles residenciales fueron: Collier 36%, Broward 25%, Indian River 25%, Palm Beach 25%, Martin 23% y St. Lucie 22%. En cítricos comerciales, se recogió A. sheldoni menos del 1%, A. pelekassi 4,0% y P. oleivora el 75,5% del tiempo. No se recolectó Diptilomiopus floridanus en los huertos comerciales de cítricos durante este sondeo. La frecuencia de la ocurrencia de Diptilomiopus floridanus fue significativamente mayor en lima y limón en comparación con toronja, mandarina, tangelo, naranja dulce y pummelo. Sin embargo, las frecuencias sobre la lima y el limón no fueron significativamente diferentes de las de los naranjos amargos.
