Abstract
The study aimed to determine the species of thrips infesting garlic (Batanes Red) in the Department of Agriculture–Batanes Experiment Station (DA-BES) in Ihubok 1, Basco; DA-BES Dibtung, Radiwan, Ivana; and in the Calderon Farm in Radiwan, Ivana, Batanes. Sampling was done in February 2020. A total of 950 adult female thrips were collected from all study sites. The majority of the thrips were collected from DA-BES Farm in Ihubok 1, Basco with 89.89%, followed by the Calderon Farm in Ridawan, Ivana with 5.16%, and DA-BES Farm in Dibtung, Ridawan, Ivana with 4.95%. Thrips were represented by two terebrantian species, namely: Thrips tabaci Lindeman (Thripidae) with 97.37%, Anaphothrips sudanensis Trybom (Thripidae) with 2.32%, and a tubuliferan species Haplothrips gowdeyi (Franklin) (Phlaeothripidae) with 0.31%. T. tabaci was the dominant species in all study sites. A. sudanensis was found in all the study sites but in low number, while H. gowdeyi was present in two DA-BES study sites but absent in the Calderon Farm. This is the first report of A. sudanensis and H. gowdeyi infesting garlic in the Philippines.
