Life History of Bemisia argentifolii (Homoptera: Aleyrodidae) on Hibiscus rosa-sinensis (Malvaceae)

Life tables and development of Bemisia argentifolii (Homoptera: Aleyrodidae) at different temperatures.

The life history of Bemisia argentifolii Bellows & Perring (Homoptera: Aleyrodidae) on tomato (Lycopersicum spp.) was studied based on the age-stage, two-sex life table at 15, 20, 25, 28, 30, and 35 degrees C. The intrinsic rate of increase (r) at these temperatures is -0.0176, 0.0667, 0.1469, 0.1611, 0.1745, and 0.0989 d(-1), respectively. The relationship among the gross reproductive rate (GR...

Distribution and Sampling of Bemisia argentifolii (Homoptera: Aleyrodidae) and Eretmocerus eremicus (Hymenoptera: Aphelinidae) on Cantaloupe Vines

Studies were conducted to examine the spatial distribution of immature Bemisia argentifolii Bellows & Perring and immature Eretmocerus eremicus Rose & Zolnerowich on cantaloupe vines and to develop efÞcient sampling plans. More B. argentifolii eggs were found on the 3rd leaf from the terminal of a cantaloupe vine than on any other leaf. The density of whiteßy nymphs peaked at leaf position 8, w...

Antagonism between Beauveria bassiana and imidacloprid when combined for Bemisia argentifolii (Homoptera: Aleyrodidae) control.

Imidacloprid and the entomopathogenic fungus Beauveria bassiana (Balsamo) Vuillemin are both used to control the whitefly Bemisia argentifolii Bellows & Perring. We tested whether the two control strategies acted additively, synergistically, or antagonistically when combined for whitefly control. We found antagonism in that B. bassiana inhibited the effectiveness of imidacloprid. When B. bassia...

Population Ecology of Whitefly, Bemisia tabaci, (Homoptera: Aleyrodidae) on Brinjal

Reproductive Biology and Search Behavior of Amitus bennetti (Hymenoptera: Platygasteridae), a Parasitoid of Bemisia argentifolii (Homoptera: Aleyrodidae)

Amitu8 bennetti Viggiani & Evans is a recently discovered parasitoid of whiteflies in the genus Bemisia, including the serious pests Bemisa tabaci (Gennadius) and Bemisia argentifolii Bellows & PelTing. The reproductive biology and the host searching behavior of A. bennetti was studied in the laboratory, using B, a'rgentifolii as a host. The developmental time for A. bennetti from egg to adult ...
