Abstract

To establish the successive rearing of red-striped golden stink bug, Poecilocoris lewisi Distant, developmental characteristics, host plant and oviposition preference were investigated. Raw peanuts were supplied to the insect as a substitute food at 25$\pm$$1^{\circ}C$, 60$\pm$5% R.H. and under 16Lㆍ8D photo regimen. Total developmental period was 48 days: 8.2$\pm$0.4, 5.4$\pm$0.2, 8. $\pm$0.5, 6.4$\pm$0.4, 7.4$\pm$0.3 and 12.6$\pm$0.8 days for egg, first though fifth instar, respectively. The instar survival rate was 57.1% and the sex ratio was estimated to be 53 : 47 (male : female). Adult longevity was on the average 30.8 in male and 35.4 days in female, respectively. Egg of P. lewisi was globular ($\phi$1.8-1.9mm) with milky white in color The number of eggs oviposited per clutch was mostly 14. Pre-oviposition period was 25.8 days and mean frequencies of oviposition were 4.4. Female preferred to oviposit on the host plant when available, but oviposited on the artificial leaf successively when the host is not around. On the other hand P. lewisi preferred to suck the nectar of stem or fruit of Phellodendron amurense Ruprecht, Zanthoxylum schinifolium Siebold et zuccarini, Cornus officinalis Siebold et zuccarini and Cornus controversa Hemsley among the 18 plant species tested.
