“…Developmental time on second nymphal instars of B. tabaci was 16 and 17 days on both crops for the male and the female, respectively. Similar results have been reported on various plant hosts (Burnett, 1949;Gameel, 1969;Sharaf and Batta, 1985;Gerling and Fried, 2000;Ardeh, 2004;Qui et al, 2004). In contrast, Greenberg et al (2002) reported more rapid development of E. mundus on B. tabaci (biotype ''B'') on cotton (Gossypium hirsutum L.) compared to bean ( Phaseolus vulgaris L.) at 25°C.…”

Eretmocerus mundus is native to the Mediterranean region where it is often observed to enter greenhouses to parasitize B. tabaci on fruiting vegetables and other host crops. Fecundity on tomato and pepper was evaluated by placing newly emerged pairs (n = 15) of E. mundus on leaf discs infested with second instar B. tabaci, the preferred stage, maintained at 25°C and changed daily until death of the female. All whitefly nymphs were observed for host feeding and inverted to count parasitoid eggs. Adult longevity was estimated at 7.3±0.8 d on tomato and 10.1±1.0 d on sweet pepper. Fecundity (number of hosts parasitized) was estimated 147.8±12.6 per female on tomato and 171.1±21.5 on pepper. Incidence of host feeding (number of hosts killed) was significantly greater on sweet pepper than on tomato, 15.6±1.9 vs. 10.4±1.3 nymphs per female, respectively. No significant differences were detected in the duration of life stages between sweet pepper and tomato. Preimaginal survivorship in clip cages was estimated at 69.5±11.9% on tomato and 76.6±10.5% on sweet pepper, with no statistical differences. Net reproductive rate (R o ) was estimated at 63.8±8.2 and 51.0±4.4 on tomato and sweet pepper respectively. Generation time (T) was significantly greater on sweet pepper (19.3±0.5) than on tomato (17.9±0.4), but the estimate of intrinsic rate of increase (r m ) was not statistically different at 0.216±0.005 and 0.219±0.004 respectively. These values are well above those reported for B. tabaci on any crop, indicating the potential of E. mundus to control this pest on solanaceous crops in the greenhouse.

Can. Ent. 98: 707-724 (1966) Studies on the biology of Encmsia pergandiella Howard, a solitary, arrhenotokous endoparasite, revealed that fertilized eggs, which give rise to females, are deposited in whitefly nymphs preferably in second, third or foureh instar, while unfertilized eggs, which give rise to males, are deposited in Encarsia larvae at whose expense they develop. The parasite adults were observed to feed on body fluids of whitefly nymphs. Both sexes have a pupal and three larval stages, and development from egg to adult at approximately 75" F. takes 15 days for the females and 13 to 14 days for the males. Mean longevity of ehe femaks at constant and fluctuating temperatures was studied. Actual mean fecundity at 75 * 4" F. was 48.5 eggs per female, all of which were deposited during the first 70% of her life, provided hosts were abundant. Field observations revealed that E. pergandiella was present throughout the year, reaching highest numbers in the spring and sumimer. The parasite does not have an obligatory period of dormancy for all of its individuals. E. pergandiella was not able to prevent whiteflies from causing heavy damage to plants. The reason may be in the discrepancy between the rate of increase of the whitefly and the parasite.lPart of the data contained in the paper were taken from a doctoral dissertation submitted to the
