Abstract

A study was carried out to assess the damage potential and control of fruit fly on tomato in the Horticulture Unit in Universiti Putra Malaysia Bintulu Campus. Traps were used for monitoring fruit fly population over the fruiting season. The peak fruit fly populations were trapped on the 12 week after planting (W AP). The species that were caught in the traps were Bactrocera carambolae, B. papayae and B. umbrosa. The plants were sprayed with 0.5% nC24. Horticulture Mineral Oil (HMO) and 0.09% malathion every week for five weeks to control fruit flies. During the fruiting season, three colour stages of fruits (immature green, breaker yellow and red) were picked for assessment for percentage infestation by B. latifron, B. papayae and B. carambolae. Field studies showed that sprays of malathion were more effective for the control of fruit flies infestation. Percentage fruit fly infestation in red fruits was significantly higher than green and breaker stage in the field experiment and there were no significant differences between growth stages of tomato in the laboratory experiment.
