Abstract

A laboratory study aimed to compare the rearing of Sycanus dichotomus Stal. (Hemiptera: Reduviidae), as predator to Metisa plana Walker (Lepidoptera: Psychidae) by using the larvae of Corcyra cephalonica Stainton (Lepidoptera: Pyralidae) and Tenebrio molitor Linnaeus (Coleoptera: Tenebrionidae)as alternative preys was conducted. The survivorship (%), hatchability and developmental time of the predator (five nympal stages) were recorded. The mean developmental time from first to fifth nymphal stages of predator fed with the larvae of C. cephalonica was 15.16, 12.09, 11.63, 14.25 and 18.53 days, respectively, whereas larvae T. molitor were 15.21, 12.34, 12.64, 14.84 and 21.89 days, respectively. The period of development taken from eggs to adult when fed on larvae of T. molitor (156.5 days) was significantly longer (t = 6.51; df = 87; p < 0.05) than fed on larvae C. cephalonica (122.8days). The percentage nymph of S. dichotomus which successfully developed to adult when fed on larvae T. molitor was higher (81%) than when fed on larvae of C. cephalonica (76%). The range of hatchability if fed on larvae T. molitor was between 46.6 and 77.6 eggs. This result showed that mass rearing of S. dichotomus was successful when fed on T. molitor as food. It is hoped that the results of this study can initiate further research on prey-predator relationship with regard to biocontrol programms in oil palm plantations.
