Utilization of Integrated Technology for Controlling Fruit Flies in Rose Apple, Guava and Jumbo Jujube in Ratchaburi Nakhon Pathomand Samut Sakhon Provinces

Abstract

Integrated technology for controlling fruit flies in rose apple, guava and jumbo jujube was aimed to produce fruits free from fruit fly infestation. The integrated technology used composed of plot clean up, branch thinning, fruit wrapping with plastic bag, fruit fly trapping and spraying with poison bait during pre-harvesting period, and moving and grading the fruits under fruit fly-proof conditions. This project was carried out in Ratchaburi, Nakhon Pathom and Samut Sakhon provinces from October 2012 to March 2015. Sixty growers with 262 rais of orchards and 50 growers with 226 rais of orchards were selected to participate in 2013/2014 and 2014/2015 respectively. Results showed that average number of fruit flies found in treated plot were consistently less than those found in untreated plot. Percentages of un-infested rose apple, guava and jumbo jujube selected under fruit fly-proof condition at packing house of Ratchaburi Agricultural Research and Development Center were 99.2, 98.6 and 99.7% in 2013/2014 and 100, 98.8 and 100% in 2014/2015 respectively. Percentages of un-infested rose apple and guava at Nakhon Pathom Agricultural Research and Development Center in 2013/2014 were 97.1 and 98.1% whereas in 2014/2015 were 98.8 and 100% respectively. Resulting from using integrated technology for controlling fruit flies in rose apple, import suspensions by China was lifted. Consequently, the export of rose apple was successfully increased.
