Abstract

Ato Belen’s Farm is an integrated organic agricultural land situated in San Pablo City, Laguna, Philippines. The farmland produces high quality vegetables and fruit trees such as mango, pomelo, rambutan and lanzones. This study aimed to identify thrips associated with mango ‘Carabao’ and pomelo ‘Magallanes’, and to correlate population of thrips with temperature. Ten mango and 10 pomelo trees of different ages were randomly selected out of the 15 trees in the selected study site and were monitored twice a month for thrips infestation from November 2017 to March 2018. Thrips samples were collected from leaves and flowers of fruit trees by shaking and beating twigs with leaves and flowers on white illustration board. Representative specimens were cleared and mounted on slides using Canada balsam and examined under Nikon CiL research microscope. Findings of the study showed that Thrips hawaiiensis (Morgan) was the only species of thrips found infesting mango and pomelo in the selected site at Ato Belen’s nine-hectare orchard. Thrips hawaiiensis is an invasive, polyphagous species of thrips that was previously reported as pest of banana, mango and vegetables in the Philippines. Pomelo trees recorded the highest number of thrips and that there was a significant difference (p-value 0.01) in the mean number of thrips collected from mango and pomelo. The numbers of thrips were higher between the months of December to January, and in March (29 to 32oC). Moreover, there was a moderately high linear relationship between thrips population on fruit trees and temperature and this finding supports previous studies that development of different life stages of T. hawaiiensis had significant linear relationship with temperature. Surveillance of thrips on mango, pomelo and other fruit trees grown in the Ato Belen’s Farm is recommended. © Rushing Water Publishers Ltd. 2019.
