Abstract

This research was conducted at School of Sustainable Agriculture Reid laboratory in Universiti Malaysia Sabah, to evaluate the effect of insect attractant on pollination and fruit set of cucumber (Cucumis sativus L.). The objectives of this study were to evaluate the effectiveness of insect attractant in attracting pollinators and to examine the effect of the attractant on pollination and fruit set of cucumber. The experimental design was Completely Randomized Design. There were three treatments; plants sprayed with sugarcane juice at 10% concentration (vlv), jaggery solution at 10% concentration (w/v) and a control (no spray); each replicated five times. The attractants were sprayed at 7.00 am in the morning, five times and at two day intervals. Number of insect visit, percentage fruit set, individual fruit weight, length, circumference, fruit shape and seed numbers were measured. Data were then analyzed using One-way ANOVA. The results showed that, sugarcane juice at 10% concentration(v/v) significantly increased insect visit by 44±4.92 times, individual fruit weight (4.35±17.03 g), circumference (19.5±0.27 cm), seed number (181 seeds) and improved fruit shape (12% of defective fruits) compared to the control. Meanwhile, jaggery solution at 10% concentration (w/v) only increase insect visit by 37±2.86 times, seed number (123 seeds) and fruit shape (15% of defective fruits) with compared to the control. This study dearly demonstrated that the yield and quality of cucumber crops can be enhanced by using pollination attractant under conditions of low population of pollinators. A further investigation is required to make appropriate recommendations for an optimum concentration of the attractants and time of application.
