Abstract: Adult longevity, developmental time and juvenile mortality of Encarsia formosa Gahan (Hymenoptera: Aphelinidae) parasitizing the Poinsettia‐strain of Bemisia tabaci (Gennadius) (Homoptera: Aleyrodidae) on Poinsettia (Euphorbia pulcherrima Willd.) were investigated in laboratory experiments at three temperatures: 16 °C, 22 °C and 28 °C. Furthermore, the parasitoid's preference for different larval stages of the whitefly was determined at 24.5 °C. The lifespan of E. formosa decreased with temperature from one mo… Show more

“…The decreasing developmental time with increasing temperature from 25 days at 10°C to 11 days at 25°C was similar to the results with other parasitoids, as reported by Enkegaard (1993), for Encarsia formosa Gahan which decreased from 1 month at 16°C to 9 days at 28°C. (Ahmed, 1990) …”

“…However, there are several such studies on E. formosa parasitising B. tabaci (Bethke et al, 1991;Enkegaard, 1993;Xu et al, 2003). In these studies, the adult longevity of E. formosa is reported to be 4.8 d at 25.4°C (Bethke et al, 1991), 15.2 d at 22°C, 9.2 d at 28°C (Enkegaard, 1993), 17.7d at 25°C and 13.6 d at 30°C (Xu et al, 2003). In the present study, the longevity of E. bimaculata was 7.6 d at 23°C and 5.9 d at 29°C, which is shorter than that reported for E. formosa.…”

“…In the present study, the juvenile development time of E. formosa D at 20 (29.8) and 25°C (15.6) corresponds to those reported by Enkegaard (1993b) Mean daily parasitism by < 1 day old females and 3-day old females of Eretmocerus species and 5-day old females of Encarsia strains at different temperatures.
