Tóm tắt

Development time and fencudity of Bemisia tabaci (Gennadius) biotype B on soybean in Hanoi were determined at five constant temperatures ranging from 17 to 33°C. RH 80 percent. Results indicated that development time from egg to adult were longest at 17oC (62.3 + or - 0.48 days) and shorter when temperature increased (19.1 + or - 0.27 at 29°C and 18.4 + or - 0.34 at 33°C). Fencudity was highest at 25°C and 29°C and decreased at 33°C. Experimental findings show a 1/1.2 ratio of males to females of B. tabacibiotype B developing on soybean due to females have longer life and higher surviorship. Survivorship of eggs and pupa were different between host plants. Average mortality rate of eggs were highest on soybean (7.5 + or - 0.21 percent) and lowest on tomato (2.8 + or - 0.09 percent).
