In this study, it was aimed to determine some biological properties of B. angelicae on Aphis gossypii Glover (Hem.: Aphididae) which is an important pest in the citrus orchards. Totally 80±10 A. gossypii at the 2^nd and/or 3^rd nymphal stage were transferred with a help of brush on each cotton plants which was produced in the laboratory. Then, a couple of newly emerged parasitoids was released on A. gossypii for 24 hours. The cotton plants were kept in the same chamber the experiment were started and checked daily till end of the experiment. The development time, parasitization rate, and death ratio were determined by daily observation. The experiments were conducted at five constant temperatures (12, 17, 22, 27 and 32±1°C), 65% RH, 16 h (8-10 klux) daily artificial light in temperature cabinets. Although the mummies have been observed at 12°C, no adult was obtained, while no development was observed at 32°C. Development time of female individual from egg to adult took 34.7, 12.8 and 6.0 days at 17, 22 and 27°C, respectively. The mean longevity of female adult was determined as 6.4, 5.4 and 4.9 days, while 4.6, 4.9 and 4.4 days for male at 17, 22, and 27°C, correspondingly. The parasitization rates of B. angelicae on A. gossypii were assessed as 5.6% at 27˚C, 44.1% at 22˚C and 26.7% at 17˚C.
