Delphastus pusillus (LeConte), an indigenous coccinellid predator of whiteflies, including sweetpotato whitefly, Bemisia tabaci (Gennadius), feeds on all stages of whiteflies. In laboratory tests, fourth-instar and adult female D. pusillus exhibited a marked tendency to avoid fourth-instar B. tabaci parasitized by the aphelinid endoparasitoids Encarsia tmnsvena (Timberlake) and Eretmacerus sp. nr. calif amicus Howard in favor of unparasitized whiteflies. The age of the parasitoid within the whitefly influenced the extent of the avoidance. Whiteflies with first-instar parasitoids were not avoided, hut those containing third instars and pupal parasitoids were significantly avoided. The presumed causes of the avoidance include parasitism-induced hardening of the whitefly cuticle and introduction of air into the whitefly around maturing parasitoids. D. pusillus and parasitoids tend to attack different stages of the whitefly. This attribute increases temporal separation, enhancing the options for the use of D. pusillus in pest management programs in conjunction with parasitoids.

“…This predator has previously been used to control the citrus whitefly, Dialeurodes citri (Ashmead) in Georgia (Timofeyeva and Nhuan 1979) and Corsica, France (Malausa et al 1988) as well as Turkey (Yigit 1992a;Uygun et al 1997;Yigit et al 2003). S. parcesetosum was first reported on B. tabaci in India (Kapadia and Puri 1992) and in 1994 it was found attacking D. citri and B. tabaci in Syria (Abboud and Ahmad 1998).…”

Serangium parcesetosum Sicard (Col., Coccinellidae) is considered one of the important predators of whiteflies. However, knowledge about its preferences for different prey stages, species and parasitized prey is still lacking in the literature. The present work investigated the preferences of S. parcesetosum for different stages of B. tabaci, different prey species and B. tabaci parasitized by Encarsia formosa Gahan (Hym., Aphelinidae) by prey consumption at different temperatures in the laboratory. Results showed that L 2 and L 4 predatory instars of S. parcesetosum preferred puparia to nymphs and eggs of Bemisia tabaci (Genn.) (Hom., Aleyrodidae). The mean daily prey consumption was 5.1-9.0, 4.5-6.2 and 3.6-4.3 by L 2 and 6.4-9.7, 5.5-8.5 and 2.5-7.5 by L 4 for puparia, nymphs and eggs, respectively. Adult females, however, indicated a significantly greater preference for both puparia and nymphs, consuming a daily mean of 6.4-7.5 puparia and 5.1-6.7 nymphs, but only 3.0-4.7 eggs. At 18 and 30°C, all S. parcesetosum stages tested significantly preferred B. tabaci and Trialeurodes vaporariorum Westwood (Hom., Aleyrodidae) over the other three prey species offered. At both temperatures, all predatory stages preferred B. tabaci to T. vaporariorum, the L 2 instar at 18°C, showing significantly more preference for B. tabaci than T. vaporariorum. In contrast, very few individuals were consumed from Aphis gossypii Glover (Hom., Aphididae), Frankliniella occidentalis (Pergande) (Thys., Thripidae) and Tetranychus urticae Koch (Acari, Tetranychidae). At 18°C, a daily mean of 7.5-8.0, 6.6-9.0 and 6.7-8.1 B. tabaci as well as 5.3-6.4, 5.4-7.8 and 5.6-6.3 T. vaporariorum was consumed by L 2, L 4 and adult females, respectively, while at 30°C, L 2 , L 4 and adult females consumed a mean of 9.3, 8.8-9.7 and 8.3-9.7 B. tabaci/day as well as 8.3-9.0, 7.8-9.1 and 5.5-8.4 T. vaporariorum/day, respectively. S. parcesetosum L 2 and L 4 instars as well as adult females and males at both studied temperatures showed a significant tendency to avoid B. tabaci puparia after 5 days of parasitism by E. formosa and preferred to feed on unparasitized whiteflies. At 18°C, the mean daily consumption was 8.7 and 0.2 (L 2 ), 11.1 and 0.6 (L 4 ), 12.1 and 1.0 ($$) as well as 10.5 and 0.2 (##), while at 30°C the means were 15.9 and 0.5 (L 2 ), 19.8 and 1.0 (L 4 ), 18.9 and 1.2 ($$) as well as 17.4 and 0.6 (##) from unparasitized and parasitized B. tabaci puparia, respectively.

“…(Patel et al 1996), and to feed on its eggs and puparia (Shah et al 1986). On citrus, S. parcesetosum has been used to control the whitefly Dialeurodes citri (Ashmead) in Georgia (Timofeyeva and Nhuan 1979), France (Malausa et al 1988) and Turkey (Yigit 1992a(Yigit , 1992bUygun et al 1997;Yigit et al 2003). Hibiscus, infested with Bemisia argentifolii Bellows and Perring, has increased the predator's longevity compared to cucumber, cantaloupe and tomato with the predator showing a greater preference for B. argentifolii on cantaloupe and cucumber than on poinsettia in the United States (Legaspi et al 1996).…”
